• 2021-08-24黏液菌对无人驾驶汽车的启发智慧并不必通过一个大脑袋来体现We know you don’t need one big brain to act smart. 就拿蚂蚁举例吧Take ants, for example. 它们搭建错综复杂的洞穴 觅食 斗争They build intricate colonies; they farm; they wage war. 一只蚂蚁只有一个小脑袋Each ant has a tiny little brain. 但一群蚂蚁 能展现出非凡的集群智慧But together, they exhibit swarm intelligence. 即群体能以不同于群体个体的方式That means the group is smart in ways 展现出智慧that individual members are not. 你会在某些场景里见识You can see swarm intelligence at play 其他小脑袋生物的集群智慧in other tiny-brained creatures, 尤其是昆虫 比如蜜蜂especially other insects, like bees. 但奇怪的是But swarm intelligence also appears 集群智慧也会出现在in a much stranger place, 没有大脑的简单生物行为上within a single creature without any brain at all. 这些小东西能让我们更好地It’s a little blob that’s teaching us a lot 了解什么是智慧about what it means to be smart. 边缘科学 我们拜访了位于We took a trip to the swarm lab 美国新泽西州理工学院的集群实验室at the New Jersey Institute of Technology 以寻找答案to check it out. 研究黏液菌是一件……Studying slime mold is one of the…… 黏液菌可能是我研究过的最奇怪的生物之一it’s probably one of the weirdest organisms I’ve worked with. 我是西蒙·加尼尔My name is Simon Garnier. 我是一名助理教授I’m an assistant professor 供职于美国新泽西州理工学院at the New Jersey Institute of Technology. 西蒙负责集群实验室的运作Simon runs the swarm lab, 他在你可能认为发现不了智慧的生物身上which studies intelligence in places you might not 研究智慧expect to find it. 实验室的主要研究课题是The main research topic of the lab 尝试理解如何……is trying to understand how … 理解我们所说的分散系统是什么what we call decentralized systems, 在一个没有首领 设计者或负责人的系统中so system that don’t have a boss or an architect or someone in charge, 将如何实现自我管理how these systems are capable of self organizing 并通过这一自我管理and through this self-organization 找到解决问题的方法find solutions to problems. 西蒙研究的测试主体不太可能研究出结果And Simon has an unlikely test subject for his studies. 黏液菌是一种单细胞生物Slime mold is a unicelled organism, 它只是一个细胞so it’s a single cell, 但它又非常特别but it’s a very particular cell, 如果跟人们熟知的细胞作比较的话if you compare it to what people think cells are. 与通常只有一个细胞核的情况不同Instead of having one nucleus 黏液菌实际上有上百万it has actually millions of them 甚至数十亿个细胞核sometimes billions of them. 它是可以长得非常大的细胞It’s a cell that can grow over like very large sizes. 是世界上少有的I mean, one of the rare cells in the world 肉眼可见的细胞之一that you can actually see with your own eyes. 但研究如此独特的黏液菌But as unique as slime mold is to study, 也需要很多耐心it also takes a lot of patience. 黏液菌的移动速度很慢 每小时只移动1毫米It doesn’t move very fast, just a millimeter an hour. 对于研究动物行为的研究员而言For someone studying animal behavior, 最具有挫败感的事件之一就是it’s one of the most frustrating things 你不能直接观察行为发生过程that you can’t see the behavior directly. 只能耐心地等You have to wait. 除此之外 它的获取成本不高Other than that, it’s cheap. 味道也不好It doesn’t taste very good. 我不会建议人们去尝尝看I wouldn’t recommend people to eat that. 你尝过吗?You tried it? 我尝过I tried it. 它尝起来如何?What does it taste like? 它很像……你舔过地面吗?It’s more like, have you ever, like, licked the floor? 黏液菌尝起来像泥土Like, it tastes like dirt. 但黏液菌的奇特并不仅仅体现在But slime mold isn’t just weird because of 其尺寸或味道上its sizes or its taste. 也体现在让人吃惊的智慧上It also appears to be intelligent. 黏液菌并没有大脑或神经系统It doesn’t have a brain or a nervous system, 却能在硬件条件缺失的情况下but it can solve all kinds of complex problems 解决各种各样复杂的问题without any of that hardware. 随着黏液菌移动伸展As slime mold grows 所到之处能为之所接连it can keep track of where it’s been. 它可以解决觅食过程中的谜题It can solve mazes in search of food. 也可以通过训练It can even be trained to take risks 为获取巨大回报而不惜冒险in the name of a big payoff. 紧接着 是运输试验And then, there are the transit experiments. 大概十年前About a decade ago 札幌北海道大学的科学家们scientists at the Hokkaido University in Sapporo 产生了一个新奇的想法had a weird idea. 这些研究员们主要做的是What the researchers did, essentially, 给黏液菌一张地图is they gave slime mold a map 上面画着东京铁路系统of the Tokyo rail system, 每一个地铁站点实际上是and each of the station was actually a 为黏液菌设置的食物点food source for slime mold 随后任之在那片区域探索and then they let slime mold explore that area 正如我前面所说and as I said 当黏液菌在该环境中找到食物资源when slime mold find resources in the environment, 便会建立网状系统it’s gonna start building a network 将这些不同的食物点连接起来between these different resources. 几天后研究员们惊奇地发现What the researchers found a few days later 一个设计精美的铁路系统出现了was a pretty well-designed rail system 几乎临摹得与原地图分毫不差that closely mimicked the real-life map. 他们发现的是 黏液菌建立的网状联系What they found is actually built networks 与现实的铁路系统非常接近that are pretty close to up to now. 这样的网络联系建立成本不高They are very cheap to build, 与此同时but at the same time 如果建造网络过程中遇到了障碍物if there is a disruption in the network, 黏液菌总能绕过它they will be able to get around it. 黏液菌对障碍的应对方式That bit about being responsive to disruption 是我们建立运输网络时is something that our transit networks 可以借鉴学习的could learn a lot from. 我们有时需要超型计算机处理一些问题That’s a problem we need like, supercomputer to solve, 而这些生物and then this organism is just 本质上不过是一堆蛋白质和脂质的小东西essentially a bunch of proteins and lipids 却能在不借助任何外界力量的情况下and this thing is just capable of solving it naturally, 轻松地解决without any external help. 西蒙团队给我们提供帮助Simon’s team helped us to 重新进行另一个有名的运输试验recreate another famous transit experiment 这次用的是美国地图that uses a map of the United States. 并在其主要城市标记处放置食物By placing food sources on major US cities, 主要目的是让黏液菌we essentially asked the slime mold 建立一个洲际公路系统to build us an interstate highway system, 以寻求答案解释which begs the same question 很多人已提出的问题:that so much of this asks: 黏液菌到底是如何做到的?How is slime mold doing this? 答案西蒙还不太确定Simon’s not entirely sure. 但是他有一个想法but he has an idea. 现在Here in the lab, 我们正在探索的猜想之一是one of the hypotheses we are exploring 指挥黏液菌行动的大脑is that the brain of the slime mold, 实际上是它的膜if you want, is actually the membrane of the slime mold, 因为膜是黏液菌’cause the membrane is the part of the slime mold 既与外界环境接触that is both in contact with the environment, 获取外部信息with getting the outside information 又与自身生理机能相联系and in contact with the physiology of the organism, 获得内部信息的组成部分so getting the inside information 也就是说尽管没有大脑Meaning even without a brain, 一个孤立的黏液菌a single bead of slime mold 也能对环境做出反应can react to its surroundings 并将信息播散至整个细胞and disseminate the information throughout the cell. 西蒙认为这一决策能力Simon thinks this decision-making power 可能来自于may come from that ability to 整个系统同步信息的能力synchronize information throughout its system. 我们将培养基在西蒙的实验室We left our Petri dishes at Simon’s lab 放置三天 任其发展for three days to let it grow. 鉴于西蒙提到过黏液菌的味道And since he mentioned it 我们也得试试看we had to try the stuff. 干杯Cheers. 干杯Cheers. 尝起来像泥土It tastes like dust. 嗯 是的 还有点像青苔Mm, yeah, it’s like moss. 对Yeah. 它确实尝起来像青苔 是It tastes like moss. Yeah, 这让我想起以前it reminds me of when we used to put moss 过圣诞节时也会用到苔藓in our nativity for Christmas. 你当时吃了吗?Oh, and you were eating it? 不 我只尝了味道而不是嗅气味No, I’m tasting it instead of smelling it. 在离开前 我们还问了个重磅问题Before we left, we also asked the big question. 我们到底能从研究过程中学到什么?What exactly can we learn from all of this? Well, 首先 研究黏液菌first, studying slime mold is 像在了解距我们很远的过去like studying the very, very distant past. 生命源于单细胞生物Life was unicellular at the beginning 这也正是一个单细胞and that’s a unicellular organism. 通过观察这样的单细胞生物如何And so, by looking at how something like this 解决复杂问题is capable of solving complex problem, 我们或多或少接触到地球生物的智能起源we sort of get to the origin of intelligence on Earth. 其次 他认为那些运输实验And second, he thinks that those transit experiments 还不是对这一智慧最好的阐释aren’t just good metaphors. 未来某天In the future, 自动驾驶汽车将形成like self-driving cars is going to be 一个大的分散系统a big decentralized system 将会有数百万辆We’re going to have millions 自动驾驶汽车奔驰在路上of these self-driving cars on the road 并且每辆车的轮子上都有计算机and essentially they are all computers on wheels 轮子上的每个计算机都将and each of these computer on wheels is going to 根据实际情况实时做出决策try to make decision in real time 比如走哪条路 怎样避开其他车辆on which road to take, how to avoid this other car, 怎样确定最佳路线等how to find the best path. 简单说来 如果我们能梳理出一个运算法则Basically, if we can tease out the algorithm 而黏液菌正是依据这一法则做出决断的that slime mold uses to make decisions, 那么我们或许能够将之加以利用并从中受益we could use some of that math for ourselves. 如果自动驾驶汽车之间能够彼此交流If self-driving cars are capable of talking to each other, 弄清楚哪个路段正拥堵figuring out where traffic is clogged, 然后通过网络自动分配运行路线they can automatically redistribute themselves in the network 这样就能减轻拥堵路段承受的压力and decrease essentially the amount of pressure on particular road, 这样对所有人都好making it better for everyone. 几天后A few days later, 西蒙将实验结果发送至我们手中Simon sent us the results of the experiment. 黏液菌建造的地图不算完美The map isn’t perfect, 但是与耗资耗时巨大的参照公路网相比but it is comparable to a highway network 毫不逊色that took millions of dollars and years to create. 没错 这不过是一堆培养基里的粘液So yes, this is just a bunch of goo in a Petri dish, 但这些黏液却能让你质疑but it’s goo that can make you question 自己作为人类的复杂性your own complexity as a human. 问题是如果黏液菌没有所谓的智能So the question is, if slime mold is not, say, intelligence, 只利用基本的物理化学特性解决问题and it’s using only like basic physics and chemistry to solve this problem 那么well then 如果我们能像这布丁似的黏液菌一样if we are as good as a sack of puddings 我们真的聪明吗?like are we intelligence really? 或当审视黏液菌一类的事物时or do we need to sort of really find what intelligence means 我们是否需要重新理解智能的定义?when we look at something like slime mold? 嗨 大家好!Hey everyone! 你正在观看的是全新的You’re watching this on the brand new YouTube《边缘科学》频道Verge Science YouTube channel 整个科研团队一直致力于制作视频The whole science team has been working on this 我们都很激动and we’re really excited 视频将每周上新We’re putting out a video every week 请订阅我们的频道so please subscribe to this channel 下周记得回来查看更多视频and check back next week for more. 感谢收看Thanks.
  • 2021-08-24比尔·盖茨的读书方法我不会看一本明知自己不会看完的书I don’t let myself start a book that I’m not gonna finish. 比尔.盖茨怎么看书的 你知道当你在阅读的时候You know when you are reading, 你必须很专注 尤其是看纪实类作品You have to be careful that you really are concentrated, particularly for some non-fiction book. 你有在知识的殿堂里学到新知识吗Are you taking the new knowledge in sort of attaching to knowledge heaven. 对我而言 做笔记有助于我确保For me, taking notes helps make sure 自己有认真思考书中的内容that I’m really thinking hard about what’s in there. 如果我不同意书中的观点 有时我会花很长时间去琢磨If I disagree with the book, sometimes takes a long time to read the book. 因为我怕……Because I frighten so much in the matter of…… 这真的挺令人沮丧的It’s actually kind of frustrating. 哦 拜托 说点我同意的吧 那样我才读得下去呀Oh, please say something I agree with so I can get through at the end of this book. 有一本小说叫《无尽的玩笑》So there is just one that’s the fiction book called Infinite Jest. 开卷前我在犹豫这会不会是个不悦的开始So I’m trying to decide if I started unhappy, 因为我看过电影《旅程终点》Because I watched the movie, The End of the Tour. 我很喜欢I loved it. 大卫·福斯特·华莱士遇到了一位十分有趣David Foster Wallace comes across a super interesting, 思维开阔的人broad thinking person. 如果这本书只有大概两三百页If the book was like two or three hundred pages book. 我一定会去看There’s no doubt. 就像我看那部电影 十分投入As soon as I watched that movie, I dive in, 但是这本书太过冗长复杂but it’s quite long and complicated. 你懂的 一旦开始了我就想把它看完And you know, I don’t want to make an exception. 我的原则就是一看到底It’s my rule to get to the end. 不定期的 我会换新的书看Over time, I will make the switch. 当我坐着夜读时When I’m just sitting there at night reading. 通常是看杂志或者书 这是我的习惯Often a paper magazine or a book, I’m used to that. 有趣的是我还有一个书包呢That’s ridiculous cause I carry, I have, hold a bookbag 我带着它去旅行 它很大 也有些年月了That goes on my trips with me and it’s voluminous and antiquated. 如果你想看纸质书籍If you reading books like these, 你会想一次性读上一个小时You’d want to be sitting down for an hour at a time. 否则只是走马观花 一会就忘记看了什么Because otherwise just getting your mind around, ok, what was I reading? 看书不是一件5或10分钟就能完成的事There’s not the kind of thing you can do five minutes here, ten minutes there. 除非你看的是杂志和Youtube 这些都很短Magazine articles fit, are short, Youtube videos fit into those little slots. 所以 每晚我都会花一个多小时看书And so, you know, every night I’m reading a little over an hour. 这样我就能拿起最近读的书继续看下去And so I can take my current book and make some progress.

  • 2021-08-24量子计算机——人类科技的极限在人类历史的进程中,人类技术的发展源于我们对大脑,火以及尖锐物体的探究。For most of our history, human technology consisted of our brains, fire, and sharp sticks 当火和尖锐物逐渐演变成为发电站和核武器时While fire and sharp sticks became power plants and nuclear weapons 脑研究引发了科学技术(计算机技术)的革命The biggest upgrade has happened to our brains 从1960年(20世纪60年代)开始,电脑的计算能力一直呈指数级增长。Since the 1960’s, the power of our brain machines has kept growing exponentially 电脑正变得越来越小,同时计算能力变得越来越强allowing computers to get smaller and more powerful at the same time 但这个过程即将到达它的物理极限,But this process is about to meet its physical limits 电脑中基础电子元件的尺寸正在逼近一个原子的大小Computer parts are approaching the size of an atom 在了解这个现状引发的问题之前,我们需要弄清楚一些基础知识To understand why this is a problem, we have to clear up some basics 简而言之——KurzgesagtIn a Nutshell -By Kurzgesagt 电脑是由非常简单的零件组成的,A computer is made up of very simple components 做着很简单的事情doing very simple things 显示数据,处理数据,对计算机进行控制Representing data, the means of processing it, and control mechanisms 计算机芯片由不同的模块构成,这些模块由逻辑门电路构成,而逻辑门电路则由晶体管构成Computer chips contains modules which contains logic gates, which contains transistors 晶体管是计算机进行数据处理的最小单元A transistor is the simplest form of a data processor in computers 晶体管其实是个开关,可以关闭和开启,从而控制信息传输basically a switch that can either block, or open the way for information coming through 计算机中的信息是比特(位)构成的This information is made up of bits 可以设置成0或1的二进制数形式来表达Which can be set to either 0 or 1 计算机通过一些比特(位)的组合来储存和表达复杂的信息Combinations of several bits are used to represent more complex information 晶体管可以组合起来构成逻辑门电路,逻辑门电路的工作也非常简单Transistors are combined to create logic gates which still do very simple stuff 例如,如果所有的输入都是1,那与门会输出1,否则会输出0For example, an AND Gate sends an output of 1 if all of its inputs are 1 and a output of 0 otherwise 逻辑门电路可以组成计算机模块,对数据进行有意义的处理,比如把两个数字相加Combinations of logic gates finally form meaningful modules say for adding two numbers 一旦你可以做加法,那当然也可以做乘法Once you can add, you can also multiple 一旦你能做乘法,你基本上可以做任何事了and once you can multiple, you can basically do anything 实际上其中的基础运算要比一年级数学还简单Since all basic operations are literally simpler than first grade math 你可以把计算机想象成一组七岁的小孩在计算最简单的基础数学题You can imagine a computer as a group of 7 year old answering really basic math questions 足够多的计算机串联起来,就可以计算任何问题了A large enough bunch of them could compute anything 从天体物理学到塞尔达传说(游戏名)from astrophysics to zelda 然而,随着电子元件越来越小However, with parts getting tinier and tinier 量子物理学使事情非常棘手,Quantum physics are making things tricky 简单地说,晶体管是一个电子开关,In a nutshell, a transistor is just a electric switch 电流就是从一个地方运动到另外一个地方的电子,Electricity is electrons moving from one place to another 所以,晶体管可以阻断单向流动的电流。So, a switch is a passage that can block electrons from moving in one direction 如今,一个典型的晶体管仅有14纳米,Today, a typical scale for Transistors is 14 nanometers 这比一个HIV(艾滋病)病毒还要小8倍,Which is about 8 time less than a HIV virus’ diameter 比一个红细胞还要小500倍。and 500 times smaller than a red blood cells 当晶体管缩小到只有几个原子那么大的时候,As transistors are shrinking to the size of only a few atoms 电子可能会通过本应被阻隔的通道,Electrons may just transfer them to the other side of a blocked passage 这个过程称为量子隧道。viral process called Quantum Tunneling 在量子领域,物理现象和我们平常截然不同。In the quantum realm, physic works quite differently from the predictable way were used to 那么这种传统的电脑就不再有进步的可能了,and traditional computers just stop making sence 我们的技术进步正接近一个物理屏障,We are approaching a real physical barrier for our technological progress 为了解决这个问题,To solve this problem 科学家正试图通过建造量子计算机,scientist are trying to use these unusual quantum properties to their advantage 来使用这些神奇的量子特性。by building quantum computers 在普通电脑里,比特是信息的最小单位,In normal computers, bits are the smallest unit of information 而量子计算机的最小单位是量子比特(量子位),它也可以设置为两个值Quantum computers use Qubits which can also be set to one of two values 量子比特(量子位)可以是任意的两能级量子系统A qubit can be any two level quantum system 可以旋转产生磁场,也可以成为单光子such as a spin and a magnetic field or a single photon 0和1是系统可能存在的状态0 and 1 are the system’s possible states 它们就像光子的水平态和垂直偏振态一样like the photons horizontal or vertical polarization 在量子世界中,量子比特不一定只处于一种固定的状态In the quantum world, the qubit doesn’t have to be just one of those 它可以是任何两种状态It can be any proportions of both states at once 这就是所谓的量子叠加态This is called Superposition 但是,一旦你要对它进行确切的测量,比如我们让光子通过滤光器But as soon as you test its value say by sending the photon through a filter 那么它就必须要确定一个状态,到底是水平态还是垂直偏振态It has to decide to be either vertically or horizontally polarized 因此,当量子比特的状态没有被观测到的时候So as long as it’s unobserved 量子比特就可能处在一种0和1的叠加状态,并且你没法预测它到底是0还是1的状态The qubit is in a superposition of probabilities for 0 and 1 and you can’t predit which it’ll be 但是你一旦对它进行观测But the instant you measure it 叠加状态就会坍塌缩成其中一种特定的状态It collapses into on of the definit states 量子叠加态就是游戏规则的改变者superposition is a game changer 传统比特可以在同一时刻,在四种不同立体基阵下各拥有两种状态(不是8嘛@_@)For classical bits can be in one of two to the power of four different configurations at a time 有十六种可能的组合但你只能使用其中一个that’s 16 possible combinations at which you can use just one 而量子比特处于叠加态时,就可以同时处在十六种组合之中For qubits in superposition however, can be in all of those 16 combinations at once 每多出一个额外的量子比特,这个数就呈指数式增长This number grows exponentially with each extra qubit 20个量子比特就能存储相当于如今一百万比特的存储容量20 of them can already store a million values in parallel 彼此间的纠缠使量子比特拥有快速反应和能力的同时保持不确定性,A really wired and uninsured property qubits can have is Entanglement 也就是说每个量子比特都可以极快地从一个状态切换到另一个A close connection that makes each of the qubits react to a change in the other state instantaneously 无论它们相隔有多远no matter how far they are apart 这意味着当测量一个被纠缠的量子比特时,你可以直接调用它的同伴的属性This means when measuring just one entangled qubit, you can directly to use property of it’s partner’s 而不必专门去查看without having to look 操纵量子比特的想法也是别出心裁Qubit Manipulation is a mind bender as well 一个标准的逻辑门工作原理是接收一组简单的输入,产生某个确切的输出A normal logic gate gets a simple set of inputs and produce one definite output 一个量子门要输入旋转叠加态的概率A quantum gate manipulates an input of superposition rotates probabilities 并产生新的叠加态作为输出and produces another superposition as its output 所以量子计算机设定某些量子比特作为量子门,用来约束它们和操纵它们的(叠加态)概率So a quantum computer sets up some qubits, apply quantum gates to entangle them and manipulate probabilities 最终测量到的数据是崩塌的叠加态,能确切等于0和1then finally measures the outcome collapsing superposition to an actual seqence of 0s and 1s 这里的意思是你在启动机器的同时就得到的大量可能计算结果What this means is you get entire lot of calculations that are possible with your setup all done at the same time 最终你只能得到测量结果中的一个,它很可能正是你想要的Ultimately you can only measure one of the results and it’ll only probably be the one you want 所以你大概还要再测一次So you might have to double check and try again 但是如果巧妙的运用量子叠加态和量子纠缠效应But by cleverly exploiting superposition and entanglement 量子计算机就会比传统计算机的工作效率高无数倍this can be exponentially more efficient than would ever be possible on a normal computer 因此,就算量子计算机可能不会替代我们的家用电脑So, while quantum computers will not probably not replace our home computers 但在其他一些领域,它们同样有着巨大的优势in some areas, they are vastly superior 其中一个就是数据检索One of them is database seraching 为了在数据库查找东西,一个普通计算机不得不查看所有词条to find something in a database, a normal computer may have to test every single one of its entries 量子计算机算法却只需要存入时间的脚本Quantum computers algorithms need only the square root of that time 对于大数据来说,又完全不同了which for large databases, is a huge difference 量子计算机最出名的应用是破坏信息安全The most famous use of quantum computers is ruining IT sercity 现如今人们可以查看电子邮件和使用网银,都是依托了加密的安全系统的保护right now you are browsing email and banking data is being kept secure by an encryption safety system 这个系统给所有人公共密钥用来加密,但编码的信息只有你自己可以破译in which you give everyone a public key to encode messages only you can decode 问题是,公共密钥实际上可以被用来计算你的个人密钥The problem is that this public key can actually be used to calculate your secret private key 幸运的是,在普通电脑上做这种计算至少需要几年的时间来尝试和犯错Luckily, doing the necessary math on any normal computer would literally take years of try and error 而量子计算机由于拥有指数级增长的运算速度,呼吸之间就可以完成But a quantum computer with exponential speed-up could do it in a breath 另一个激动人心的新用途是模拟仿真Another really exciting new use is simulations 量子世界的模拟仿真对资源的要求非常高Simulations of the quantum world are very intense on resources 即使是计算模拟大型物体例如分钟子,也经常出错and even for bigger structures such as molecules they often lack accuracy 那么,为什么不用真实的量子来模拟量子物理现象呢?So why not simulate quantum physics with actual quantum physics 量子仿真技术可以透视蛋白质,从而引发机器变革Quantum simulations could provide new insights on proteins that might revolutionize medicine 现在我们不知道量子计算机,会成为专家的工具Right now we don’t know if quantum computers will be just a specallized tool 还是全人类社会的科技革命or a big revolution for humanity 我们不知道技术的极限在哪里,We have no idea where the limits of technology are 只有一个方法能找出来。and there’s only one way to find out 这个视频由澳大利亚科学院支持This video

  • 2021-08-24Facebook是如何偷取大家的浏览量的几天前,脸谱网骄傲地宣布他们刚刚达到了每天八百万播放量的成就A few days ago, Facebook proudly announced that they’d acheieved eight billion video views a day 这真是令人印象深刻,直到你知道,在2015年第一季度,That’s really impressive, until you learn that in the first quarter of 2015, 一千个Facebook上浏览最多的视频中有725个,被盗,累积170亿次观看。725 of the thousand most viewed videos on Facebook were stolen, amassing a total of 17 billion views. 网址和目录聚合器从youtube窃取了视频文件,去感染Facebook。Sites and content aggregators steals videos from YouTube to go viral on Facebook. 这些视频病毒因为Facebook在作弊。These videos go viral because Facebook is cheating. 他们操纵的算法使视频上传到他们的播放器适合YouTube链接。They rig their algorithm so that videos uploaded to their player are preferred to YouTube links 因为用户应被长时间留在网站上,所以Facebook可以向他们展示尽可能多的广告。Because users should be kept as long as possible on the site, so Facebook can show them as many ads as possible. 这毕竟是他们的商业模式。This is, after all, their business model. 但播放方面也存在欺骗But it also cheats when it comes to views 即使视频被静音,一次播放还是会在三秒后被计算在内A view is counted after three seconds, even if the video is muted 这意味着由于自动播放,如果你足够慢慢滚动你的进度条,你被计算为播放者。Which means that because of auto-play, if you scroll through your timeline slowly enough, you count as a viewer. 这意味着约定是可怕的That means engagement is terrible 相比于YouTube,Facebook的视频播放数几秒钟后急转直下,因为大多数数字并不是真实的Compared to YouTube views, Facebook views plummet after a few seconds, because most numbers are not real 但大数字令人印象深刻,所以Facebook继续作弊But large numbers are impressive, so Facebook keeps pretending 虽然强迫的病毒营销很奇怪,真正的问题是所谓的“抢劫”,偷盗视频While this forced virality is weird, the real problem is the so-called "Freebooting", the stealing of videos 因为Facebook倾向于它自己的观众,被偷来的视频会传播给比之前更多的用户Since Facebook prefers its own viewer, stolen videos reach way more people than the original. 最近这种事情越来越多Lately this has happened to us more and more often 最近的例子,两天内积累了320万播放和14万次分享The most recent example amassed 3.2 million views and 140 thousand shares in two days, 而我们原本的视频只有10万人播放,1000次分享While our own post reached just 100 thousand people and got shared 1000 times. 其他创作者受到的打击更大。Other creators are hit even harder. Smartereveryday的视频持续被盗,达到了1700万次观看Smartereveryday’s videos get stolen constantly, getting viewed up to 17 million times 但即使这样,与歌手吉布森的例子比也相形见绌,其偷盗的病毒视频在他的Facebook页面达到8600万次播放But even this is dwarfed by examples like Tyrese Gibson, a singer who steals viral videos like this one, with 86 million views on his Facebook page. 他也补充了购买他的音乐的链接。He adds a link to buy his music too. 在这方面他不是一个人He’s not alone in this, 一整组的人在偷盗别人的工作上,都有自己的在线业务A whole group of people have built their online presence around stealing other peoples’ work 这对独立创作者真的不利This is really bad for independent creators. 与流行的看法相反Contrary to popular belief 偷来的内容给创造者接近零曝光率Stolen content gives creators close to no exposure at all 只有小偷和Facebook获利。Only the thief and Facebook profit from this. 高质量的内容需要许多创造力、时间和爱。Quality content takes a lot of creativity, time, and love. 拿我们做例子,一个视频按理说确实需要数百小时制作In our case, a single video literally takes hundreds of hours to make 即使我们,有超过一百万用户,也依赖于广告和曝光。Even we, with more than a million subscribers, are dependent on the ads and exposure. 没有广告和慷慨的Patreons支持我们,我们没法制作视频Without ads, and the support of our generous Patreons, we could not make videos. 对于一个小创作者,一个病毒视频可能意味着职业和业余爱好之间的区别For a small creator, a viral video can mean the difference between a career and a hobby 在YouTube上这种偷窃并不是一个问题,因为他们从被盗起就提供主要保障保护内容,On YouTube this kind of theft is not a problem because they have major safeguards that protect content from being stolen, 虽然目前的ID系统远非完美,尤其是电影评论家和玩家Although the content ID system is far from perfect, especially for film critics and gamers. Facebook,另一方面,假装一切都很好,不断宣布一个又一个里程碑。Facebook, on the other hand, pretends everything is fine and constantly announces one milestone after the other. 但事情并不好。让我们看看去年Facebook公布的用户声明版权的流程:But things are not fine. Let’s look at the process of claming your copyright on Facebook in the last year: 1.从粉丝得到一个电子邮件或推,给你一个直接链接到你的视频的链接。1. Get an email or tweet from a fan that gives you a direct link to your video. 不可能在Facebook上搜索你的视频,你只能依靠运气发现你被偷的视频。It’s not possible to search for your videos on Facebook yourself, you depend on luck to find your stolen videos. 2.在谷歌上搜索“Facebook侵犯版权”,因为实际上这样更快2. Search for "Facebook copyright infringement" on Google, because it’s actually faster this way 3.填写一个长得烦人的表格3. Fill out an annoyingly long contact form. 4.看着你被偷的视频播放上升4. Watch the views on your stolen videos rise. 5.Facebook最终把视频删除5. Facebook finally pulls the video 视频已经很方便地得到了其应得的99%播放Conveniently, the video has already gained 99% of all the views it will ever get 小偷一点也不需要担心任何负面影响The thief doesn’t have to fear any negative consequences at all. 这就是成功的创作者经常要对付的事情This is what successful creators have to deal with constantly, 除了失去的曝光和金钱,他们只是感觉被侵犯了and on top of losing out in terms of exposure and money, it just feels like violation to be treated like that. 在最近的一份声明中,Facebook宣布,他们想要改变In a recent statement, Facebook announced that they want to change 但是很难认真对待他们,仍然需要一些日子等待偷来的病毒视频被撤下But it’s hard to take them seriously when it still takes days for a stolen viral video to be taken down 并且Facebook不分享从中获取的利润and Facebook does not share the profits made from it. 在这一点上,Facebook并不是创作者期待与之合作的伙伴At this point, Facebook is not a partner creators look forward to working with. 他们以偷来的内容和漠视原创内容创作者建立了视频帝国They’ve built their video empire on stolen content and disregard for original content creators. 这绝对是一个价值数十亿美元的公司完全无法接受的This is absolutely unacceptable for a corporation worth billions of dollars. Facebook已经测试各种货币化模型,将给予上传者部分广告收入Facebook is already testing various monetization models that will give uploaders a cut of the ad revenue 对当前的状态来说,这是令人不安的Which, with the current state of play, is troubling. 现在,这只被大型媒体公司测试,但作为创作者,我们不想觉得正在被要求或被巨头Facebook考虑Right now this is merely being tested with big media companies, but as creators, we don’t feel like we’re being asked or being taken into consideration by the giant that is Facebook. 作为一个观众,你能怎么帮忙?What can you, as a viewer, do to help here? 如果你发现FB偷盗的内容,在评论中发表原始内容链接If you spot stolen content of FB, make a comment linking to the original content. 警示最初的创造者,因为只有他们可以提交一份版权报告Alert the original creator, because only they can file a copyright report 分享这个视频或由Smartereveryday完成的视频Share this video or the one done by Smartereveryday 我们都想要同样的事情—基于创造力、社区和伟大的东西的免费互联网。We all want the same thing, the free internet that is based for creativity, community and great stuff 我们衷心希望Facebook将成为一个参与者,而不是这一目标的一个障碍We sincerely hope that Facebook will some become a parter, rather than an obstacle to this goal 想获取更深的信息,我们推荐Hank Green的这篇文章For more indepth information, we recommend this article by Hank Green 如果你想支持我们在全世界的在线视频上生存,或制作更多的视频And if you want to support us in our quest to survive in the world of online videos.

  • 2021-08-24阿西莫机器人可以踢足球了我现在已经来到了布鲁塞尔的本田科技研发中心将要见见这里最有名的代表I’ve come to Hondas Technical Centre in Brussels to meet one of its most famous representatives -虽然到现在我也不清楚它到底是谁– though I’m not quite sure who it is yet. 讲真 我将要见的不是人 而是机器人…Turns out, who I was about to meet wasn’t actually a human, but a robot… Honda’s 本田旗下有名的仿人机器人-阿西莫famous humanoid robot – Asimo. 阿西莫能和人类互动 所以如果你伸出手它就会和你握手Asmio has been designed to interact with humans. So if you reach out your hand it will shake -它手掌心的传感器能感觉到你的触摸同时头部的摄像头会记录你的移动it – sensors in its palm detect your touch while cameras in its head track your movements. 阿西莫的稳定化技术确保它能对你扰乱它平衡的行为做出回应Asimo’s stabilization technology enable it to react if you upset its balance. Moving 如果你推它 它会后退 如果你把它拉向你自己 它就会往前backwards mid shake if you push it or stepping in if you pull it towards you. 阿西莫这项最新的技能是经过近三十年的研发得出的成果This latest version of Asimo is the product of almost three decades of development. 这能追溯到1968年本田研发的第一个能行走的机器人It all started back in 1986 when Honda built a robot which could walk, all be it very slowly 虽然走得很慢很笨拙 到了1988年 这个机器人能够走得更像人类and clumsily. In 1988 it was developed to walk more like 到了1993年 机器人有了完整的躯体直到1996年本田的机器人才开始变得国际化a human and in 1993 a torso was added. By 1996 Honda’s robot had become intimidatingly 谢天谢地 在1997年 机器人被用于当宇航员之前 它被设计成了更小的尺寸large so in 1997 it was shrunken to a less threatening size, thankfully, before being 2000年 本田推出了最新型的代表着先进 进步 有里程碑意义的made autonomous. In 2000 Honda unveiled Asmio which stands for Advanced, Step, in Innovative, 可移动的机器人阿西莫 站立时130cm的高度-相当于成年人坐着的高度-Mobility. Standing 130cm tall – the same height as a seated adult – it’s the perfect size 是用于在家里帮忙的机器人的最佳高度for helping out around the home. 这些年阿西莫被不断地改善 现在已经灵活到可以做运动了Over the years Asimo has been constantly developed and it’s now mobile enough to play sports. 然而 任何运动之前都最好热一下身 机器人也一样However, it’s wise to warm up before any physical exercise, even for a robot, and as 并且阿西莫能够以6m/h的速度奔跑还能倒行和单足跳跃well as run at 6 miles an hour Asimo can walk backwards and hop. 它还会踢足球 那么现在是机器人大战人类之射门比赛It can also kick a ball. So time for a quick robot vs human penalty shootout. That’s 这对阿西莫来说小菜一碟但是阿西莫在擅长射门的同时还擅长守门吗?one nil to the autobots. But is Asimo as good at saving a shot as it is taking one? Clearly 很明显本田还没有把阿西莫训练成一个好的守门员Honda hasn’t trained Asimo to be goal keeper just yet… 踢足球是一项很容易渴的运动但我们有阿西莫 它能为我们提供一些饮料Football is thirsty work, thankfully, Asimo can get you some refreshments. With hands 有着一双有13个自由度的手阿西莫能执行一些非常精细的任务that have 13 degrees of freedom it’s able to perform delicate tasks such as opening 例如拧开瓶盖倒出饮料 这对人类来说轻而易举a bottle and pouring a drink . This may be unremarkable for a human but it’s an incredible 但对机器人来说却是值得惊呼的成就achievement for a Robot. 阿西莫总共有57个自由度 这使得阿西莫能够跳舞In total Asimo has 57 degrees of freedom and this allows it to dance – while its 52 volt 同时52伏的电池足够它跳上40分钟看起来这个机器人实际上比一些人还要灵活…battery can keep it going for 40 minutes. Looks like this robot actually has better moves than human. 总之 能做到这种程度就已经足够了… Anyway enough of that… 阿西莫很高兴和你见面 但现在我必须离开了Well Asimo it’s been nice to meet you, but I have to go now.Don’t forget to write, 别忘了给我发邮件或是任何其他与你的机器人有关的东西!email…Or whatever your robots do! 别忘了给我发邮件或是任何其他与你的机器人有关的东西!email… Or whatever it is you robots do!
  • 2021-08-24戒网瘾就靠它了大家好 这里是Lew 给大家带来最新一期的视频What’s up guys, Lew here back with another video. 今天要介绍的产品有点奇怪Today I got a weird one. 说实话我现在有点紧张And I’m a little bit nervous, to be honest. 在我面前的这个盒子里放着一个叫做Pavlok的东西Inside here is something called Pavlok. 据我所知 这是一个高科技产品 其实我也不太清楚It’s a piece of tech – this is what I know – like, what I know is actually pretty vague. 这个东西是用来帮你戒除坏习惯的It’s a piece of tech that helps you break bad habits. 真是个好东西!Gotta love those. 这个产品的官网提供了一个戒烟的案例The case study on their site is about someone quitting smoking, 但还有一个人 我觉得是该公司的创始人 but there’s also another guy – I think it’s the founder of the company 他用这个产品来戒除自己吃炸玉米片上瘾的毛病who he used this tech to quit eating tortilla chips. 那么这东西有什么用呢?把它戴在你的手腕上What does it do? It sends a shock to your body. 一旦你又犯了坏毛病的话 这个装置就会电击你的身体Every time you do the bad habit, like a real shock, you wear it on your wrist. 亚里士多德曾说过:“每天反复做的事情造就了我们“We are what we repeatedly do. 然后你会发现 卓越不是一种行为 而是一种习惯”Excellence, then, is not an act, but a habit.”–Aristotle 为Pavlok充好电 把它戴在手腕上 保持全天佩戴 长按闪电标志Charge Pavlok, place it on your wrist, wear throughout the day, pressing firmly on the lightning Pavlok就会发出触感反馈 然后把它和你的坏毛病以及欲念配对bolt will release Pavloks stimulus. Pair the stimulus with your bad habit or craving. 那么在贪吃玉米片的案例中So in the case of the tortilla chips, 你每吃一片都会电击自己一次 这样一来 电了自己很多次后you shock yourself enough times, every time you eat one, 你再看到玉米片时 就会想到之前的电击and you start to think of the shock when you see tortilla chips. 于是你再也不想让他们进入你的生活了 这就是Pavlok的原理And you don’t even wanna let them in your life anymore. That’s the idea here. Alright. 减少欲念 – 披萨 冰淇淋 – 我爱死披萨了!Reduce cravings – pizza, ice-cream – Love pizza! 甜甜圈 一看到就会想吃的好东西 然后 “滋”的一声Doughnuts. You see the doughnut, you want the doughnut. Zap! 因为你肯定会按下按钮来触发电击 所以最好对自己诚实一点Cause you gotta press the button, you gotta do the shock. So you gotta be honest with yourself still. 这就是电击手环 闪电标志在前面 看起来像块表Here’s the bracelet. Lightning bolt on the front, it’s kinda like a watch. 我猜 这个就是电击装置 天啊 我已经开始觉得疼了This, I guess, is the unit. Oh man, I can feel the pain already. 看起来像个小金属块It’s like a metal brick. 再来是一根微型USB线 我觉得是在这儿充电And, a little micro-USB cable. I guess charges this guy up here. [笑声]我说这东西电得是有多疼 居然值得卖给你[Laughter]I mean how much of a shock can it be, they’re selling it to you. 天啦 接下来可不好玩了Oh man, it’s not gonna be fun. 好的 假设我正犯了坏毛病 比如抽烟So lets say ok, alright, I’m doing the habit – I’m smoking the cigarette, 或者 贪吃了个甜甜圈 冰淇淋什么的 再比如说我又赖床了or, I’m eating the chip, or icecream, doughnuts, I’m not waking up on time. 感觉自己像个噩梦 是全人类的灾难了I’m a nightmare, I’m a disaster of a human being. 然后在犯毛病时按下这个 And then I just press this, when I get that – Whew. 来真的吗?Should I do it? 我真要按吗?Do I press down? 毫无感觉Nothing. 这东西肯定得先充电 对吧?It must. Need to be charged. Right? 看看它闪烁着的诡异红光 真吓人Look at those creepy red lights. Hey? Just creepy. 好的 在它充电期间 我得赶快搜一下它的应用程序So I’m gonna go ahead and search for the app real quick while it’s charging. Pavlok …有了Pavlok. 实际上你正在做的 从某种程度上来说 是去入侵自己的大脑Essentially what you’re doing, is your are kinda hacking your mind in a sense. 但实际上…简单点说 你就是戴了一个人类版本的电击狗项圈But you are – lets not get it twisted – you’re wearing the human equivalent of a dog shock collar 声音警告 振动 电击Beep, vibrate, zap. 你可以在这儿调整它们的强度You can adjust the power of these things, here. 来看看用这东西 我是能得到好东西 还是不好的东西(笑声)Lets see if I get something positive or negative out of this. [Laughter] 实际上就是被电一下的事儿Just something about getting shocked. You know? 好吓人!No fun! 我是要点一下屏幕吗?What do I tap it? 轻触以连接手机 配对成功Tap to connect. Pair. 好了 然后呢?能快点电我一下吗?Ok, so, so what? Can I do a zap real quick? (长叹)[Loud sigh] 哎哟!Oh! 可恶!Damn! (嘟囔)[Unintelligible] 这可一点儿都不好受It’s not a good feeling. 为什么受伤的总是我?Why am I being such a whip? 再来一次Here we go again. (尖叫声)[Screams] 这东西一定有用 我已经觉得自己被狠狠教训一顿了 我再也不想…That would train me. I’m feeling trained already.I don’t even wanna 天啊 简直疯了 刚才的强度是百分之五十Man that is crazy, that’s uh, 50 percent 才百分之五十就这么疼?That’s 50 percent. (紧张地叹气)[Nervous sigh] 那要是百分之百的强度呢?100 percent? 来看看这个强度调节器What about my ticker? 噢Ugh. 我们慢慢来 这次先升到百分之七十 然后再到百分之百Let me go up slowly. I’ll go to 70, and then I’ll go to 100. 哎哟!Oooh! 这可不像蚊子嗡嗡 这简直是狮子吼It’s not a little buzz, it a (Loud sound). 这次来百分之百的Let’s go to 100. 哎哟喂!Oooh! (笑声)[Laughter] 这电击可不是盖的 但问题是你还是需要些自制力That shock is no joke, the problem is you still need some self-control. 你得有足够的意志力 告诉自己: “一旦心生邪念 就立马按下按钮”You need to be in charge enough to say, “when you get the craving hit the button.” 这个轻触按钮是干嘛的 长按闪电符号What is this tapping thing. Press firmly on the lightning bolt. 哎哟!Bamn! 我觉得 要是你真心想用电击来约束自己But I can see, like, if you truly wanted to get committed to attach your craving to that shock, 而且你的意志又足够坚定 那么你肯定能改过自新and you got willpower to do it. You might be able to rewire yourself. 把遥控给你的另一半 然后用蓝牙把它连在家庭网络里Give the remote to your spouse. Connect it on Bluetooth around the house. 当你拿出一根烟You pick up that cigarette. (电击声)[Shock sound] 哇!Woah!

  • 2021-08-24控制沸水的气泡是的,水的沸腾So, boiling of water is an 非常有意义incredibly useful process. 它能让我们有效地移出It allows us to move a lot of 许多热量 并且heat very effectively and you 你经常能在不同行业看到它often see it in many different industries 事实上世界大多数地区的 In fact most of the 电力来自于worlds electricity comes from 采用蒸汽循环方式的发电厂power plants that run some sort 但是水沸腾的方式of steam cycle. But the way in 基本上which water boils is basically 由气泡的形成来控制controlled by the formation of 我们永远无法these bubbles. And we’ve never 很好的控制had great control of how these 这些气泡的产生bubbles are generated. 但现在我们正在尝试And what we’ve been trying to do 这么做,去改变is in fact change is 沸腾的过程 在某种程度上boiling process in a way 如此做法 使得系统的有效性such that we can maximize the 达到最大化efficiency of the system or 还能提高热传递性能improve the heat transfer performance. 所以我们现在使用这些表面活性剂分子So what we can do here is use these surfactant 就本质而言molecules which are commonly 他们通常也被称作洗涤剂known as detergents, essentially. 现在 我们在这儿要做的就是And what we do here is by 应用一个电场applying an electric field we 我们就可以促使这些表面活性剂分子can allow these surfactant 吸附在表面上molecules to absorb to the surface. 同时在这个过程中 And in this process 有这些分子在表面of having these molecules on the surface, 你就可以开始这个you can initiate 煮沸的过程 并且有气泡产生 the boiling process and have bubbles form. 现在当你 And now when you 改变电场的两极now change the polarity of the 或是在某种程度上减少电场的时候field or reduce the field in a way, 事实上 之后就能促使then you can in fact allow 这些表面活性分子these surfactant molecules to 离开表面move away from the surface 并关闭气泡and turn off the bubble 生成过程generation process. 从根本上来讲我们从未Fundamentally we’ve never 认真思考过really thought about boiling 用这种方法使其沸腾 这是一个在某种程度上in this way, where it is sort of 可控制过程的地方a controllable process. The 类似的 我爱使用的是analogy I like to use is the 电阻 基本上沸腾electrical resistor. Boiling is 就像电阻一样basically like an electrical 它是从不resistance that resistance never 改变的 不管怎样我们changes. However what we’ve 所做的事情 从某种程度上来说仅仅是done is we’ve kind of created a 创造出了一个晶体管 一个我们transistor in a way where we 能在动态中改变热敏电阻can change the thermal 的地方 是的resistance on the fly.

We can control the 我们能控制温度steam output. We can control the 而且或许我们现在temperature.

  • 2021-08-24特斯拉创始人——埃隆·马斯克的故事您正在收看的是冷流科技You are watching ColdFusion TV. 冷流科技[Music playing] 大家好 欢迎再次收看ColdFusion视频栏目Hi, welcome to another ColdFusion video. 那么 我敢肯定如果你订阅了这个频道So I’m sure if you have been subscribed to this cannel, 你肯定听说过不少有关埃隆 • 马斯克的事you’ve had heared a lot of Elon Musk. 他就是突然从天而降He is the guy who seems to just arrived from another planet 让整个世界措手不及to casually disrupt the world 改变了众多产业游戏规则的男人one industry at a time. 很多人将其视为Many see him as one of the great industral minds 21世纪伟大工业家之一of the 21th centry. 工程师之王The engineers’ engineer. 就算你没听说过此人 那很有可能Even if you haven’t heared of him, chances are 你也已经见识过他的影响力了you still see his influence. 知道电影《钢铁侠》吧?You know that movie “Iron Man”? 事实上As it turns out 马斯克为好莱坞创造出托尼 • 斯塔克Musk provided a large amount of inspiration 提供了不少灵感for the Hollywood character, Tony Stark. 实际上 《钢铁侠》第二部的很多场面In fact, parts of “Iron Man” 2 是在SpaceX公司取的景were actually filmed inside and outside the SpaceX 而这家公司正是埃隆 • 马斯克的私人火箭公司Elon Musk’s privite rocket company. 马斯克甚至在电影里亲自出镜Musk even made a camera in the film. 你可能还听说过特斯拉公司的Model S型轿车You may have also heared of the Tesla Model S. 这个全电动车项目It’s a fully eletric car project 由马斯克主导spearheaded by Musk 被美国国家高速公路安全管理局给予5.4分的高分 满分才5分and was awarded 5.4 out of 5 from the national highway safty administration. 这是有史以来 该机构给予机动车的最高评分The highest rating ever given to an automobile. 而在此之前 他还与人共同创造了一种支付系统This all comes after co-founding a payment system 你可能有所耳闻:that you may have heared of: PayPalPayPal. 巧的是Coinsidentally, PayPal就是那家曾经Paypal was the very same company that used to 雇佣了几位Youtube创始人的公司 employ the founders of Youtube. 那么问题来了 埃隆 • 马斯克究竟何许人也?So, who is Elon Musk really? 他凭什么成就了这一切How did he achieve all these things 背后又有怎样的故事?and what’s the story behind him? 我们将通过本片一探究竟In this video, we will find out. 咱们废话少说Let’s get straight into it. 早年生活The Early Days 埃隆 • 马斯克于1971年出生在南非Elon Musk was born in South Africa in 1971. 母亲曾做过模特 父亲是个工程师His mother was a model and his father was an engineer. 他是三个孩子中的老大 提前一年进入小学He was the oldest of three kids and started primary school a year early. 孩提时代的埃隆有点不合群As a kid, Elon was a bit of a outsider 喜好读书 但常因为聪明遭到欺负and love to read but got picked on for being smart. 不像弟弟妹妹Unlike his brother and sister, 埃隆的社交生活并不丰富Elon didn’t have a great social life 但他并不介意 而是将时间花在看漫画书上but didn’t mind spending time reading comics instead. 除了有点不合群Dispite being an outsider, 人们很早就看出来 他是个天资聪慧的孩子It was clear early on, that he was a smart kid. 他的弟弟 金波 • 马斯克His brother, Kimbal Musk. 金波: 埃隆十岁那年 参加了IBM的测试When Elon was ten years old, he got tested by IBM. 结果是他获得了IBM有史以来And he was found have one of the highest aptitudes 编程方面的最高分之一they have ever seen for computer programming. 大概在个阶段 他对编程产生了兴趣Around this time he had an interest in programming 想通过课程学习and wanted to take some classes 但他已经远远超过了教他的老师but he was way ahead of his teacher. 有趣的是 这与我们在Interestingly, this is the same trend ColdFusion视频《脸书有多大》中马克 • 扎克伯格that we saw with Mark Zuckerberg in the ColdFusion episode: 的发展轨迹颇有相似之处“How big is Facebook?” 1993年 他12岁At age 12 in 1993 马斯克自学编程Musk just taught himself computer programming 创造出一款名为 《Blastar》 的游戏and created a video game called “Blastar” 后来以500美元出售which he sold for $ 500. 上下求索Finding His Way 1989年 17岁的马斯克In 1989, a 17 year-old Musk 从南非搬到加拿大moved from South Africa to Canada. 最终 他前往美利坚合众国And eventually he would move to America 赴宾大学习and attend college at the University of Pennsylvania. 毕业后 马斯克前往加州After graguating, Musk moved to California 在斯坦福大学攻读物理学硕士and began graduate studies in physics at Stanford University. 他感兴趣的领域是太空探索His main interset is space exploration. 但实际情况是 在这段时间But the thing was, right at this time 世界正经历着变革the world was going through revolutionary shift. 互联网浪潮即将达到顶点The internet boom was reaching full swing. 仅仅两天后 埃隆离开斯坦福 投身互联网After just 2 days, Elon would leave Stanford and take advantage of the boom. 这个决定改变了他的人生轨迹This decision would alter the course of his life 也极大地改变了世界and ultimately, change the world. 崭露头角The Beginning 从斯坦福退学后After dropping out of grad school 马斯克很快成立了他的第一家公司Musk quickly established his first company, Zip 2Zip 2. 该公司提供在线报纸Which provided on line newspapers 还有地图和企业名录with maps and business directories. 他于1999年将公司出售给康柏He sold the company in 1999 to Compaq 售价3亿7百万美元for $307 million. 埃隆个人从中获得2千2百万美元Elon himself neted $22 million out of the sale. 虽然Zip 2 给报业带来了革命Although Zip 2 revolutionalized newspapers. 埃隆对它没能在世界舞台上 起到关键作用深感沮丧Elon was frastrated that it wasn’t a game changer on the world stage. 几个月后 马斯克推出了另一个项目In a matter of months, Musk was on to the next project. 1999年 他创立了X.comIn 1999, he founded X.com 这家在线支付公司最终成为Paypalan online payment company that eventualy became Paypal. 它被Ebay斥资15亿美元收购It was acquired by Ebay for $1.5 billion in stock 其中1.8亿进了马斯克的口袋of which $180 million was given to Musk. Paypal从根本上改变了人们之间Paypal foundamently changed the way people transfer money 转账的途径to one another. 同时也改变了买卖的方法And also, how they brought and sold things. 在某些情况下 那时For some context, at that time 人们邮寄支票的做法还很普遍it was still commen for people to mail checks to each other 这个过程缓慢又痛苦a very slow and ached process 完成一笔交易要花费几周时间taking weeks to complete a single transaction. 马斯克已经改变了金融业Musk has changed the financial industry 但现在 他想要改变全人类的发展道路but now he wanted to change the course of humanity itself. 2002年 他创立了太空开发技术公司In 2002, he founded Space Exploration Technologies 又称为SpaceXotherwise known as SpaceX SpaceX这家公司 专门从事研发 制造SpaceX is a company that creats and manufactures 以火箭技术为主的载具vehicles primarily rocket technology. 目标? 降低空间飞行成本The aim? To reduce the cost of space flight 以将人类的生存半径拓展至地球以外in hopes of expending human life beyond earth. 推进这个雄心勃勃的计划需要大笔资金支持Doing such ambitious project required a great deal of money. 一开始 马斯克发现很难为SpaceX募集资金Musk initially found it impossible to get funding for SpaceX. 因为很多投资人将其视为无底洞which many investers saw as a pipe drain. 马斯克颠覆了商业领域的传统Going against traditional business practices 将自己的所有积蓄投入公司Musk channeled all his money into the company to 好使其成为现实make it a reality. 皇天不负有心人And a reality it became. 目前 SpaceX拥有与美国航空航天局签署的16亿美元合约SpaceX currently has a $1.6 billion contract with NASA 内容是将补给和人员运往国际空间站to resupply and eventualy ferry people to the international space station. 马斯克成功地将到达国际空间站的成本Musk has reduced the cost of reaching the international space station 降低了80%by over 80%. 如果你想了解更多关于SpaceX的信息If you want to know more about SpaceX Coldfusion也有相关视频there’s already a ColdFusion video on it. 之后请查询内容标签So check out the discription afterwards. 在SpaceX公司之后 马斯克又于2004年成立了特斯拉After SpaceX, in 2004, Musk help found Tesla. 特斯拉Roadster 是该公司第一款车型The first Tesla car, the Tesla Roadster 也是第一辆was the first electric vehicle 改变了人们对电动轿车陈旧看法的车型to break the public’s conceptual model of a electric car. 之后又出现了Model S轿车After this came the model S 其中最快的一款可以在2.8秒内从0加速到70迈of which the fastest models can do 0-70 mph in 2.8 seconds. 当然 如果你想了解更多关于特斯拉的情况Of course, if you want to know more about Tesla Motors 我也有视频可供观看I’ve gotta a video on that as well 所以请查阅内容标签so you can check the discription. 2013年 埃隆公布了他最新的奋斗目标In 2013, Elon introduced his latest endeavor. 超级高铁The Hyperloop. 这是一种在理论上It’s a form of transpotation that theoretically 能在半小时内把乘客从三藩市运送至洛杉矶的交通工具could send people from San Francisco to Los Angeles in half an hour 通过密封管道得以实现by the way of pressurized tubes. 这当然不是全新的想法Of course it’s not a new idea 但马斯克组织了一场设计该交通系统的竞赛 But Musk has overseen a competition to build the transport system 以推动类似技术的进步to advance the technology. 同样的 我也已经制作了有关视频Once again, I’ve already done a video on this 你们可以自行观看so you can check the discription. 埃隆还是SolarCity公司背后的Elon is also one of the major driving forces 主要推手之一behind SolarCity, 该公司由他的一名表亲成立a company found by one of his cousins. 在特斯拉公司的指导下 他近期收购了SolarCity公司Under the guides of Tesla, he recently bid to buy the company. 马斯克还推出一款壁挂式充电电池组PowerwallMusk also released a Powerwall 这个简单的设备可以不依赖公共电网满足家庭用电需要a simple battery pact designed to power the home off the grid. 你也能找到关于该产品的视频A video on the Powerwall is in the discription. 虽然最近取得了一系列巨大成就Despite his enormous recent sucsess 他也并非一帆风顺it hasn’t all been smooth sailing. 他的两家旗舰公司Both his flagship companies SpaceX和特斯拉SpaceX and Tesla Motors 曾经距失败仅一步之遥came alarmingly close to failing. 特斯拉的第一款电动车 RoadsterTesla’s first electric car, the Roadster 目前面临着一系列问题faced a ongoing string of problems 同时该公司在2008年金融危机时and the company sufered financial woes 遭遇了严重的财政困境during the 08 crash.

And what can we learn from him? 咱们来看看Let’s take a look. 如何选择职业What You Chose to Do in Life 不论你从事什么工作Whatever area that you get into 即便你是行业里的顶尖高手given that even if you are the best of the best 也难免会失败there’s always a chance of failure. 所以 我觉得选你所爱的工作才重要So, I think is important that you really like whatever you are doing. 呃 如果你不喜欢En, if you don’t like it 生命太短暂了 不值得浪费life is too short. 如果你喜欢你的工作If you like what you are doing 即便没在工作的时候 你也会时刻想着you think about it even when you are not working. 这是你自然会全身心投入的事业it’s something that your mind is drawn into. 呃 如果你不喜欢自己的工作En, and if you don’t like it 一切都是空谈 个人看法you just really can’t make it work, I think. 个人潜能Personal Potential 不用非得有大学文凭There’s no need even to have a colledge degree 如果是从名牌大学毕业If somebody graduates from a great university that maybe 只是证明他们that may be an indication that they 有成就事业的可能will be capable of great things 但也不一定but it’s not necessarily the case. 你知道 看看You know, if you look at, er, 举几个例子吧say, people like 比尔 • 盖茨 拉里 • 埃里森 斯蒂文 • 乔布斯Bill Gates, Larry Ellison, Steven Jobs 他们都没能从大学毕业these guys didn’t graduate from college 但如果你有机会雇佣他们but if you had a chance to hire them 当然 这肯定是个好主意of course, that would be a good idea. 努力工作Hard Work 你得超级努力地去工作You need to work super hard 超级努力是什么意思呢?So what does super hard mean? 我和我弟弟开办第一家公司的时候Well, when my brother and I were starting our first company. 我们没有公寓 只是Instead of getting an apartment, we just 租了一间小办公室 睡在沙发上rented a small office and we slept on the couch. 去基督教青年会洗澡and we showered at the YMCA 我们努力工作 我们只有and we were so hard that we had just 一台电脑 所以只能白天运行网站one computer, so the website was up during the day 晚上我来编程and I was coding at night. 一周七天 天天如是Seven days a week, all the time. 只要还醒着就努力工作So work hard like every waking hour. 这就是我要说的That’s the thing I would say. 痛苦经历Hardships 那段时间真的很痛苦It was terrible time. 嗯…Um… 倒霉事都聚到一起了Yeah, everything was going wrong at once. 开始是三次火箭发射失败Three rocket failures in a row at the beginning and 然后又是特斯拉财年即将结束Tesla financing round is falling apart 一切濒临崩溃all fall aparts. SolarCity运行遇到困难…The SolarCity was having difficulties… 离婚…getting divorced… 想想都害怕It’s really terrible. 是的 在2008年底Yeah, at the end of 2008 第四次发射成功the 4th launch worked. 嗯 那真是Um, which is 我们当时就那么多钱了that was all the money we have 多一分也没有了there is nothing more. 第二天早上And then the next morning 美国航空航天局打来电话说我们赢得了订单NASA called and said that we won this 价值15亿美元$1.5 billion. 采访者:就在第二天?马斯克:是的 就在第二天–interviewer: the next morning?–Musk: Yeah, the next morning. 我记得是个周二或者周三的晚上I think it was the Tuesday night or a Wednesday night 正是我们结束特斯拉财年的时候was the, um, was when we closed the financing round for Tesla. 是圣诞节前夜晚上6点And it was at 6 p.m Christmas eve. 最后一天的最后一刻 我们活下来了The last hour of the last day when it was possible. 本来圣诞夜之后的几个小时或者几天内We would have gone bankrupt a few hours after 我们可能就破产了or a few days after Christmas eve. 呃 如果那次没搞定我们就只能关门大吉Er, if it went wrong then we are closed. …以及放弃…and Giving Up 当遇到三次连续发射失败的时候When you had that 3rd failure in a row. 你想过 我要放弃吗?Did you think: I need to pack this in? 从来没有Never. 为什么?Why not? 我从不放弃I don’t ever give up. 我的意思是 除非我死了I mean, I’d have to be 或者完全丧失行动能力了 否则决不放弃dead or completely incapacitated. 重要的是 成功不需要你有多牛BSo essentially, you don’t need to be great to be something. 永不言弃 选你所爱 努力工作Never give up, love what you do and work hard. 我完全同意This seems to check out with me 因为如果你看过我的 “有多大” 系列影片because if you’ve watched my How Big series, 你就知道很多那些开创了you’ll know that a lot of the guys that 世界上最大公司的人们started some of the world’s biggest companies today 都有同样的品质all possess these characteristics. 所以 现在你了解了成功的知识So now that you have some knowledge of key to success. 师傅领进门 修行在个人The choice of how you apply it is up to you. 这就是埃隆 • 马斯克的故事So that’s the story of Elon Musk 讲了讲他现在的工作a bit of what he’s doing today and 以及他成功的秘诀some of the trades that make him successful. 当你回顾的时候When you think about it 会觉得有趣的是 所有这些成就it’s pretty cool that all these achievements were done 都是一个在学校时总被欺负by the kid who used to be bullied in school 而且没有多少社交生活的孩子办到的and didn’t have much of a social life. 这就是咸鱼翻身吧Sometimes the underdog really does come out on top. 感谢你的耐心观看Thanks for watching the whole way through this video. 请订阅我们的频道Feel free to subscribe to this channel. 有空就点个赞Give this video a thumbs up 在留言中分享你的看法and leave your comment sharing your thoughts. 这里是Dagogo 你正在收看的是冷流科技This is Dagogo, you have been watching ColdFusion TV. 下次见了And I’ll see you again soon for the next video. 感谢你们的收看 享受生活 祝好运Thanks guys, enjoy yourselves and have a good one.

  • 2021-08-24迪士尼到底有多大?你正在收看的是冷流科技You are watching ColdFusion TV 冷流科技[Music playing] 大家好 欢迎再次收看ColdFusion视频栏目Hi, welcome to another ColdFusion video 当提到华特迪士尼的时候你会想到什么呢?What comes to your mind when I say Walt Disney? 有些人可能会想到一些经典的动画片Some of you might think of classic cartoons 或者一些现代的电影佳作and modern-day movie master pieces 还有些人可能会想到主题公园或是一家大众媒体传播公司Others, a grant theme park or a mass media holding company 当然 还可能有人只会想到这是一个人的名字and others, still… a man 所有这些想法都是正确的All of these are accurate 但是 在华特迪士尼公司这个名字后面到底有什么传奇故事but what’s the story behind the Walt Disney Company 并且迄今这家公司到底有多大呢?and how big are they today? 众所周知 它是由 华特·迪士尼 一位矮小的天才As we all know, it started with a man named Walt Disney 一手创立的a short genius 但是他一生的经历but the details of his life 以及使得他与众不同的地方and the aspects that made him different from others 都没有详细的记载are hazy to most 华特·迪士尼是一位很有野心的创作者Walt Disney was an ambitious innovator 他从不言弃he seemed to never give up 当然 他也有另外的一面He also had another side 那就是 他是个完美主义者he was a perfectionist 他对他自己及同事的要求都十分严苛who was particularly stern to those he worked with 在这个视频中 我们将会全面的了解华特In this video, we’ll learn all about Walt 以及他创立的公司and the company he created 一家从创立至今一直走在时代前沿的公司which is still relevant “a better part of the century” later on 让我们一探究竟吧Let’s begin 序言Prelude 1901年在芝加哥出生Born in Chicago in 1901 华特在当时是家里5个孩子中Walt was a pretty regular kid of the day 普通的一个and one of five children 在小学期间 他表现出了在绘画上过人的天赋During primary school, he expressed an interest in drawing 并且能够通过描摹and would practice sketching 他爸爸报纸封面上的画练习写生by copying the front-page of his dad’s newspaper 一段时间以后 华特的爸爸让他上了绘画课After a while, Walt’s dad got the boy some drawing lessons 随后在高中期间他便开始为学校里的报社画画and he would subsequently draw for his high school paper 但事实上But the thing was 那时并没有人觉得他会是伟大的画家nobody thought of him as a particularly great artist 在17岁的时候At age 17 华特决定向一些杂志社投稿 希望他的画能得到出版Walt decided to send some of his drawings to magazines for publication 但是 遭到了一致拒绝but they were all rejected 接下来的几年里 碰壁再坚持再碰壁…在华特的生活里轮流交替着Rejection and persistence would be altering familiar to Walt over the next few years 在1919年 华特终于在In 1919, Walt finally got a job 普雷斯曼鲁宾的广告公司得到了一份工作at the Pesmen-Rubin Commercial Art Studio 但一年之后就被解雇了but was laid off a year later 在经历了和一位前同事创建自己的美术工作室失败以后After failed to attempt at starting an animation studio of his own with an ex co-worker 华特最后在堪萨斯市广告公司得到了一份工作Walt landed another job at the Kansas City Film Company 在这里 华特第一次了解到卡通片This is where Walt was first introduced to animated cartoons 他也因此看到了一个更为广阔的新世界His eyes were opened to a new world 而1920年刚好正是无声动画短片The 1920s was when animation really started taking off 开始衰弱的时期in the former silent short comedy sketches 华特看清了局势并产生了灵感Walt saw what was going on around him and took inspiration 他借来了有关动画制作的书籍和一个摄影机He borrowed book on animation and a camera 然后便开始在自家房子后面的小屋里and began to start shooting his own cartoons 制作他自己的动画片in a shed behind his house 在创作期间During his work in the shed 华特偶然发现了一种比他工作的堪萨斯市广告公司Disney came across a superior animation technique to the one 所使用的更先进的动画制作技术that was used at the Kansas Art Company where he worked 他试着劝说他的老板采用这种新的制作方式但没有成功After failing to persuade his boss to use the better animation method 然后他就接着独自制作Disney continued to work on his own cartoons by himself 随后便产生了《小欢乐》这部动画片and we call these cartoons “Laugh-O-Grams” 接着在华特20岁没多久时 他便创立了人生中第一家动画公司“Laugh-O-Grams” would end up in the name of Walt’s first animation studio 并命名为欢笑动画公司which he created shortly after at the age of 20 大部分的人对于自己的头一次创业都很谨慎Most people would be conservative with their first business venture 但华特却恰好相反but Walt was passionate 他花光了所有的钱去聘请动画家一起He went out and spent all of his investment money 制作他的名为《爱丽丝在卡通国》的新作on hiring animators for a film called “Alice’s Wonderland” 这部作品是基于《爱丽丝漫游仙境》改编的based on the 1865 novel “Alice’s Adventures in Wonderland” 并且也是华特天才的创作代表作之一This project was one of the first instances of Walt’s creative genius — his way 那时 传统的动画片You see, old experimental films of the day 都是以现实场景为背景 再结合会动的手绘人物combined live action backgrounds with an animated character on top 而华特的《爱丽丝在卡通国》却刚好反过来Walt reversed this for Alice’s Wonderland 他把现实中的人物置于卡通的背景里putting the live action character within an animated world 不幸的是 他宏伟的计划还没有完全实施Unfortunately, Walt’s grand plan didn’t catch 在制作的中途公司便破产了and half way through production in 1923, the studio went into bankruptcy 但华特仍旧没有放弃自己的梦想but Disney still knew where his passion lay 他想要成为一名大师He wanted to be an artist 他卖了他的摄影机 去了好莱坞 当时的动漫产业中心He sold his camera, and went to Hollywood, the center of the cartoon industry at that time 华特在成功后也感慨道在年轻的时候经历几次失败也是很重要Walt would later stated that it is important to have a failure when you are young 在好莱坞的时候While in Hollywood 这个满怀期待的年轻小伙子请求过很多动画制作公司订购他的动画the starry-eyed young man asked old big studios to take him on 但他们都说“不”They all said “No” 但华特最终还是幸运的Walt finally got lucky 当他成功地把只制作了一半的《爱丽丝在卡通国》的版权when he managed to sell a half-finished version of “Alice’s Wonderland” 卖给一个纽约电影分销商时to a New York film distributor 他幸运地得到了一份制作两季短片的合同landing a contract for two seasons 为了做好这些短片To make the short episodes of the Alice’s films 华特和他的哥哥Walt teamed up with his brother, Roy 当时正好住在好莱坞的罗伊一起who was live in Hollywood at that time 创立了华特迪士尼公司and formed the Walt Disney Company 到了1927年 华特开始厌倦了爱丽丝系列动画By 1927, Disney had gotten sick of the Alice’s series 并想要制作一些纯粹的动画片and wanted to make some purely animated pieces 因此 他便创作了一系列关于一只名为His first project was a series of short films “奥斯华”的兔子的动画短片about a rabbit called “Oswald” 出乎意料的是 奥斯华系列短片马上就被环球公司订购并发行Surprisingly, the Oswald episodes got distributed by Universal 并且还在各大戏剧院表演and made us way into major theaters 到了1928年 本是该签一份新合同的时候In 1928, when it came time to renew the contract of “Oswald the Rabbit” 而此时环球公司却拒绝签约并声称要自己制作这部短片Universal refused and decided to produce the character themselves 其实 这种现象当时在圈内十分常见This was actually a common practice at that time 因为发行商们一般都拥有动漫人物的发行版权as the distributors owned the completely rights to the characters 迪士尼 又一次 不幸跌入低谷Disney, once again, was left out in the cold 但他并没有放弃But instead of calling a quit 他决定再创作一个全新的角色he decided that he needed a new character 在和一些亲友归家的火车上On the train home with some of his family members 华特一路苦思冥想he was brainstorming “我觉得它应该是一只老鼠 就叫莫蒂默”“I think it’ll be a mouse, and I’ll call him Mortimer,” he stated 华特的母亲却强烈建议这只老鼠的名字应该叫Walt’s mother strongly recommended that the name of the character “米奇”should be “Mickey” 米老鼠Mickey Mouse 华特竭力的为这个新角色寻找发行商Walt still struggled to find a distributor for this new character 并且他深知他的动漫制作方法需要革新了and he knew that he needed to do something revolutionary here 于是 他便引进了一种全新的He capitalized on a brand new technology 用于电影制作并没有多久的新技术——that had just be in cooperated into the film industry — 声音Sound 华特明白 要想成功 他必须做到最好Walt knew that he had to do a better than anyone else’s to succeed 而接下来要说到的就是华特是如何做到的and here’s how Walt did it “过去 我们通常都是拍完再配音”“… that we used to put the sound on afterwards” “在…在拍摄期间你是无法为影片加上声音的 也就是我们现在说的配音”“and… and those days you couldn’t do what we called ‘dubbing’ today” “因为 拍摄的时候经常有很多不可避免的噪音”“where you could make a lot of cracks” “当时的配音技术并没有现在这么科学精准…现在配音的时候你还可以离开配音室”“It wasn’t yet the science… that the… that you can get away with so” “我们那个时候所有的声音必须同时录制”“We used to have to do everything at one time” “期间动画片也要同步播放”“and we used to have to run the cartoon” “必须保证人物是有声的效果”“We’d have the fellows with the sound effects” “人要同步配音”“we had the people with voices” “背景的管弦乐也要同步演奏”“we had the orchestra going, and everybody had to synchronized” 回到1928年那个年代 这简直就是有革命性意义的动画片Back in 1928, this was revolutionary 人们那时还并不能理解People wouldn’t have been able to comprehend 一个动画人物吹口哨 唱歌that an animated character could whistle, sing 竟有相对应的声音同步播放and have corresponding sounds on film 迪士尼便是这个有声动漫行列的先行者Disney had just pioneered fully synchronized sound for cartoons 很多人把这看成迪士尼成名的起点Many held this as the start of the Disney we know today [米奇吹口哨声][Mickey’s whistling] 其实在迪士尼之前 观众看过有声的动画片Audiences had seen cartoons with sound before 但却没有看过如此同步 如此天衣无缝的有声动画片but never synchronized, yet not as perfectly as this 他们都爱上了这样的动漫They were blown away 有声的米奇也因此红遍全球Mickey and synchronized sound had made world famous 在这次革新之后After this revolutionary innovation 迪士尼并没有停止向动画制作添加新元素的探索Disney can’t push in the boundaries of animation 到了1934年And when 1934 came around 他和他的团队一起着手制作制片以来最为艰巨的新片he and his team got to work on the biggest animation project ever undertaken 全世界第一部全彩的动画片 斥资150万美元The fisrt full-color, feature-animated film, costing $1.5 million 名为“白雪公主”It was called “Snow White” 继“白雪公主”之后 佳作一部接着一部After “Snow White”, came many meticulously animative master pieces 像“木偶奇遇记” “幻想曲” 和 “小鹿斑比”like “Pinocchio”, “Fantasia”, and “Bambi” 除了这些影片 迪士尼还开始涉足其他领域Despite all of these, Disney wasn’t going to stop at just film 到了1950年In the 1950s 他把注意力转移到了和之前完全不一样的事物上He would focus his attention on something completely different — 那就是 主题公园Theme parks 以前 主题公园只是孩子们的天堂Traditionally, amusing parks were only for children 而陪同的父母却无事可做leaving tag-long parents with nothing to do 华特便设想了这样一个地方Disney envisioned a place 在这里 大人和小孩可以一起冒险玩耍where both children and parents could share fun experiences together 这个地方就是 迪尼斯乐园This place was Disneyland 这座乐园在1955年7月17日开放and was opened on July 17th of 1955 在接下来的几十年里Over the next few decades 迪尼斯在很多领域开辟新天地 如拍摄电影 动画片 电视连续剧Disney would break new ground in many areas as film, animation, TV 甚至是科研and even technology 在1959年 迪士尼也作为先锋开创了360视频In 1959, Disney would also pioneer 360 video 这项技术 后来被叫做环幕视频The technique, then called circle-vision 360 它使用九个摄像机 以期构建一个360º的视觉效果use 9 cameras to stitch together a 360 video 这样 九个相机共同为一个剧院工作for 9 screens and a custom theater 在1963年 迪士尼公司创造了独有的机器人In 1963, Disneyland featured electro-mechanical robots 这是人类创造的第一个如此类人的机器人This was the first time people had ever seen such life-like technology 起初 一些参观者甚至认为这就是真人演员Some early visitors thought the robots were actually actors 在那时 这个野心勃勃的公司创造的步伐没有一刻停歇By this stage, the creative direcrion of the company was unstoppable [音乐][Music] 到了今天Present Day 他的公司成立了92年后的今天Ninty-two years after his founding 迪士尼仍是大众传媒主力军Disney is a massive media power house 毫无疑问 它很大It’s absolutely huge 但今天 我们要探究出它到底有多大but of course, we are here to find out exactly how big 先从实际规模的大小来看Let’s start with the physical size 位于 佛罗里达 奥兰多的迪士尼主题公园 占地43平方英里Disney World, located at Orlando, Florida, covers 43 square miles 大约有两个曼哈顿这么大That’s about twice the size of Manhattan 或者说和旧金山差不多大or roughly the size of San Francisco 艾波卡特 那个代表着“明天实践原型社区”EPCOT, which stands for “Experimental Prototype Community of Tomorrow” 的主题公园是四个迪士尼世界的主题公园中最大的一个is the biggest to the four theme parks in Disney World 那是源自沃尔特的设想that was actually envisioned by Walt 是一个未来的宜居城市to be a livable futuristic city 最近 迪士尼也在中国建立了一个迪士尼乐园Recently, Disney also opened a Disneyland in China 这也是迪士尼在国外投资最大手笔的一次making it their largest foreign investment ever 媒体所有权Media Ownership 从传媒方面看 迪士尼旗下有很多有名的传媒公司In term of media, here’s a selection of some well-known companies owned by Disney 这里有:沃尔特 迪士尼电影公司 迪斯尼自然 迪斯尼动画We have: Walt Disney Pictures, Disneynature, DisneyToon Studios 出品了《星球大战》的卢卡斯电影公司 Lucasfilm, which brought us Star Wars of course 也在2012年被迪斯尼以40.6亿美元的价格收购and was purchased by Disney in 2012 for $4.06 billion 还有皮克斯动画And then Pixar Animation 那个由卢卡斯动画图形部门独立而成的动画公司which actually grew out of Lucasfilm’s Graphics Department in 1979 也在2006年被迪斯尼收购and was bought by Disney in 2006 在2009年以四十亿收购的Marvel动画Marvel Studios, bought in 2009 for $4 billion 试金石影片 发行了如《修女也疯狂》Touchstone Pictures, which gave us movies like “Sister Act” 《谁害死了兔子罗杰》 《死亡诗社》之类的影片“Who Framed Roger Rabbit”, and the “Dead Poets Society” 还有好莱坞RecordsWe also have Hollywood Records 也被称为“ABC”的美国广播公司American Broadcast Company, otherwise known as “abc” 还有ESPN A&EWe have ESPN, A&E 生命 历史频道Lifetime, the History Channel 和多渠道网络制造室YouTubeand the YouTube multi-channel network — Maker Studios 迪斯尼也入股副媒体Disney also partly owns Vice Media 与二十一世纪福克斯公司合作in collaboration with 21st Century Fox 现在我想问你们一个问题So I’m just gonna ask some of your guys a quick question 你以前知道这些传媒公司都是迪士尼旗下的么?Did you know that Disney owned all of those media companies? 我只知道一部分 但并不知道全部I knew that they owned some of those, but not that much 而且我觉得有些难以置信 一个公司旗下竟然能够有这么多著名的分公司and I think that it’s a little unnerving that one company can own so much 但 迪士尼就是这么强大but I guess it is what it is 接下来 让我们着眼于迪士尼的财务方面Next let’s take a look at the financials 去年 迪士尼共挣了524.6亿美元Last year, Disney made $52.46 billion in revenue 其中净收入为83.8亿美元with a net income of $8.38 billion 目前 迪士尼身价为880亿美元and currently owns $88 billion in assets 共拥有180,000位员工The number of employees, 180,000 如果在净收入方面作比较For comparison on the net income front 微软是122亿美元左右Microsoft comes in about $12.2 billion Alphabet是163亿左右Alphabet comes in at $16.3 billion ExxonMobil是220亿美元ExxonMobil, $22 billion 苹果是534亿美元and Apple, $53.4 billion 好了 视频接近尾声了 在彻底结束之前All right, so near the end of the video, but before we finish off

  • 2021-08-24世界上最大的飞行器Airlander10您正在收看的是冷流科技You are watching ColdFusion TV. 冷流科技[Music playing] 大家好 欢迎再次收看ColdFusion视频栏目Hi! Welcome to another ColdFusion video. 航空业在创新上进入了迟滞阶段Aviation has gone through a bit of innovative dull page 这是从2003年 协和式超音速客机告别蓝天开始的ever since the Concorde left our skies in 2003. 13年过去了 情况有所好转Now after 13 years, things maybe moving again. 比如 几周前For example, a few weeks ago 一艘名为 “阳光动力号” 的太阳能驱动飞机a solar powered plane, named Solar Impulse, 刚刚完成环球飞行just finished its flight around the globe. 刚刚完成环球飞行just finished its flight around the globe. 另外 目前我们还在拭目以待 电动轻型飞行器的批量生产in addition, we’re currently seeing the introduction of mass produced electric light aircraft 制造商包括斯洛文尼亚的蝙蝠飞机公司等等from manufacturers such as Pipistrel in Slovenija. 但本期节目将重点关注的是But in this video, we’re gonna focus a bit 航空创新领域的一个奇葩on the strange side of new aviation innovation. 这是世界上最大的飞行器This is the world’s largest aircraft 几天前刚刚进行了首航测试and it just embarked on its maiden test flight a few days ago. 这款飞行器被命名为 “天空登陆者10”The aircraft, called the Airlander 10 是由飞机 直升机和飞艇组成的 “四不像”happens to be part plane, part helicopter and part airship. 且听我慢慢道来Let’s learn a little more. 这款飞行器的概念诞生于2010年The concept was born in 2010 when 彼时 美国军方与英国一家 “混合航空器有限公司”签约the US militry contracted a British company called Hybird Aero Vehicles 制造一种可用于to make an aircraft that could be used 长时监视和情报搜集的航空器for long endurance surveillance and intelligence. 经过几年研发 原计划于2013年被取消After a few years of development, the plan was canceled in 2013 原因是美国军方无法继续负担其开销because the US militry couldn’t afford it any more. “混合航空器有限公司” 简称 “HAV”Hybird Aero Vehicles or HAV for short, 从美国军方手上回购了该项目bought back the craft from the US military 如今由英国政府and now has funding from the UK government 和欧盟资助其后续研发and the EU for further development. 稍微进行调整后 “天空登陆者 10” 便诞生了After a bit of tinkering, the Airlander 10 was born. 能见到如此憨态可掬的飞行器 可不是件容易的事It’s not everyday that you come across a cuddly flying machine. 但这个肯定假不了But this is difinately one. 这个位置软软的 摸一摸就吱吱作响It’s a little bit soft here and squeaky. 但可别被着蠢萌的外表迷惑。 这里面其实有But don’t be fooled. There’s actually 超过3万立方米的氦气over 30,000 cube meters of Helium inside here 也就是说 里面的氦气约等于1百万支that’s roughly equivalent to a million party balloons 派对气球up here~ 表面很硬It’s very rigid 其实里面并没有什么结构and this doesn’t actually have a structure. 表面坚硬的原因 是这里面充满了气体It’s reasonably rigid, because of all the gas inside. 它是台…漂亮的机器It is one…beautiful machine. 好了 那么有什么不同寻常的地方吗?Alright, so what’s the big deal? 基本上 它只是个看起来像屁股的大号软式飞艇Essentially, it’s just a big blimp that looks like a ass. 恩 不完全正确Well, yes and no. “天空登陆者 10” 实际上还是蛮酷的The Airlander10 is actually kind of cool. 因为它使用了一种新技术Because it’s using the new technology 这种新技术是可行的in a way that functions. 斯蒂芬 • 麦格里南Stephen McGlennan HAV公司首席执行官who is the CEO of HAV, 他的公司制造了”天空登陆者10″ the company that makes the airlander10 以下引用他的解释:explains, quote: “把它想象成真正巨大的直升飞机“Think of really giant helicopter “天空登陆者10” 能做到的The Airlander10 can do the same things 和直升机差不多that a helicopter can do. 也就是说That’s to say 提供人员和货物的空中运输provide the air transportation for people and goods 而不需要跑道without the need for a runway. 但我们的产品能装得更多 飞得更远But this thing can take more over longer distances 而且成本更低 污染更少and it’s cheaper and greener, too. 这是我大腐国的伟大发明It’s a great British invention. 它是一种混合飞行器It’s a combination of an aircraft 有固定翼飞机的部件that has parts of nomal fixed wing plane, 也有直升机和飞艇的部分”it’s got helicopter, it’s got airship.” 引用完毕unquote. 那么 这玩意如何升空飞行?So how does it get in the air and move around? 它拥有4台V8柴油发动机The ship has 4 V8 engines, 为控制方向的旋翼推进器供能that power fans for directional control. 但谈到严格意义上的升空和悬浮But when we talk about strickly lift and staying afloat. 才是亮点Things get interesting. 它主要通过两种方式保持浮空状态There’s actually 2 ways that stay afloat. 氦气置换空气时提供了60%的升力60% of the lift comes from using helium to displace air. 这是软式飞艇的方式Like any classic blimp. 另40%的升力则来自飞行器的固有形状But the other 40% of the lift inherently comes from the aircraft’s shape. 换句话说 就是它奇怪的设计了Hence, the odd design. “天空登陆者10” 在空中飞行时The body of the Airlander 10 其机体就像是巨型翼面一样actually acts like a giant airfoil as it moves through the air. 翼面又是什么?So what’s an airfoil? 翼面是机翼的横截面An airfoil is the vital cross-sectional shape of wings 它提供升力 使飞机能在空中飞行that provide lift and allow planes to fly. 其工作原理如下Here’s how it works. 翼面将空气分成2股气流The shape splits air into 2 streams. 上翼面气流比下翼面气流流速高The top stream moves fast than the bottom stream 在物理学中 快速流动的空气产生的压力较少and in physics, fast flying air generally exerts less pressure. 这意味着机翼上方的空气This means the air on the top of the wing 产生的向下的压力 要低于机翼下方的空气exerts less downward pressure than the upward pressure coming 所产生的向上的压力from the air flying under the wing. 这导致了完全向上的力 也就是升力This causes a net upward force, otherwise known as lift. 因此 “天空登陆者 10” 机体采用这种形状So integrating this shape into the body of the Airlander 10 为其在空中飞行提供了大量升力gives it a lot of lift as it moves through the air. 好了 本期节目即将结束Alright, so almost at the end of the video. 咱们看看几项数据Let’s take a quick look at a couple of stats. 这玩意有多大?So how big is this thing? 长92米 或302英尺It is 92 meters long or 302 ft in length. 巡航速度148千米每小时 或92英里每小时Has a cruising speed of 148 km/hr or 92 miles/hr. 每次可在空中停留5天And it can stay 5 days at a time in the air. 结论就是 这是一项很酷的新技术So in conclusion, it is a cool new technology. 但其成本达到3千5百万美元But at a cost of 35 million dollars 我不知道是否有什么商业用途I’m not sure if there’s any real commercial use that 能保证合理的利润回报could make a reasonable return on profit. 有消息称 该飞行器的第一种型号可运送10吨货物That being said, this first version can carry up to 10 tons of cargo. 下一种型号则能运送50吨And the next model is said to be able to carry 50 tons. 但这样的价格 我觉得还是太贵了But at that price, I think it’s too much. 但不可否认 这是种很酷的概念But it’s still a cool concept none the less. 而且能时不时看到创新 总是好的And it’s good to see some innovation every once in a while. 你们大伙有啥想法? 请在评论区留言What do you guys think? Let me know in the comments. 好了 本期节目到此结束 感谢您的收看Alright, guys. That’s the end of the video. Thanks for watching. 我手头还有别的活 所以就先制作了本期的短视频I thought I’ll just release a quick video while I’m working on some other staff 敬请期待which you will see soon. 如果喜欢我们的视频 请点赞之Don’t forget to give this video thumbs up if you like it 如果需要这个频道也可以果断订阅and subscribe if you need this channel. 我是大哥哥 您收看的是冷流节目This has been Dagogo and you have been watching ColdFusion. 再见了!下次节目见Cheers guys!

  • 2021-08-24索尼Playstation的故事你正在收看的是冷流科技You are watching coldFusion TV. 冷流科技[Music playing] 大家好 欢迎再次收看coldFusion视频栏目Hi, welcome to another coldFusion video. 索尼的PlayStation可谓是人见人爱Who can dislike Sony’s PlayStation? 正是这样一台小小的机器 带给了我们无数个欢乐的日日夜夜It was a machine that brought us countless hours of fun and was ahead of its time, 更是凭着开创了3D主机游戏时代 而成为了一款具有划时代意义的产品by ushering in the 3D era of console gaming. 那你可知道PS主机的起源和其背后的故事吗?But where did the PlayStation come from and what’s the story behind it. 本期视频 冷流科技将第一次围绕索尼公司做介绍For the first time on coldFusion, this episode will be centered around Sony. 现在 就让我们一起走进PS不为人知的种种Let’s take look at the story. 久多良木健 这位索尼的工程师 被称为PS之父The PlayStation all start with one man, Ken Kutaragi, a Sony engineer. 健最开始踏入电子游戏领域是在1988年Ken first became interested in working in video games in 1988. 当时他在看见自己的女儿用FC玩游戏之后 (FC: 俗称红白机 日本任天堂公司出品的一款家用游戏机)After seeing his daughter play games on Nintendo’s entertainment system console. 便灵感迸发地联系了任天堂公司希望为即将推出的SFC研制CD驱动器 (SFC: 第二代FC 一般称为超任) Full of inspiration, Ken approached the Nintendo to create a CD-ROM drive for the upcoming Super Nintendo system. 这款新驱动器被称为超级光碟驱动器The new drive was to be called the super disk. 任天堂同意了健的提议 并与1990年和索尼一同建立了一个研发团队Nintendo agreed and Ken brought together a research and development team within Sony in 1990. 在次年的CES上 索尼推出了兼容任天堂游戏的超级光碟主机 (CES: 国际消费类电子产品展)The following year at CES, Sony would show off the Nintendo compatible super disk, 也就我们现在所称的PS主机now codnamed the PlayStation. 这是一款多媒体娱乐主机It was a multi-media powerhouse 不仅能兼容任天堂的游戏capable of not only play Nintendo games, 还能播放音频和视频CD 读取数据CDbut also audio CDs, data CDs and video CDs, 这在1991年无疑是一个大新闻a pretty big deal for 1991. 不幸的是 索尼还未意识到 风暴即将降临Unfortunately for Sony, disaster was around the corner. 仅在主机发布一天后任天堂就发布了一份令人大吃一惊的声明Just one day later, Nintendo was surprised everyone with an announcement. 该声明中称 任天堂将中止与索尼在CD驱动器制造方面的一切合作They announced that they would break their partnership with Sony in making the super disk, 并转而与研究同一技术的飞利浦合作and partner with Philips instead to work towards the same technology. 任天堂此举彻底激怒了时任索尼总裁的大贺典雄This made the president of Sony, Norio Ohga, furious. 更加不幸的是健Even more unfortunately for Ken, 索尼公司的其他员工other employees within Sony 对于公司进入电子游戏领域大为不满thought that the idea of entering the video game industry 这些闲言碎语还传到了健的耳朵里was a bad idea and they let him know about it. 1992年 索尼内部召开了一个会议 讨论PS的未来In 1992, a meeting was held within Sony to discuss the future of the PlayStation. 会议的结论是决定停止PS项目的运营The concept was very close to being scrapped, 但健仍不死心 他三番向典雄进言 提醒他任天堂是如何让索尼全世界面前蒙羞的but Ken reminded Norio of how Nintendo had dishonored the company while the world was watching. 典雄最终同意继续PS项目的运营Norio then agreed with let the PlayStation project continue. 然而索尼公司老一代的高层们仍然对索尼进入电子游戏产业颇有微词However, the older generation of Sony executives was still very unhappy about Sony entering the video game industry. 这迫使健和他新成立的团队离开了索尼的核心层并转而在索尼音乐部门工作 This force Ken and his newly formed team to leave Sony’s main headquarters, and continue work at Sony music headquarters. 面对新项目的走向问题 索尼面临着抉择With groundwork for the new projects orderd, Sony had a choice to make. 新的PS主机究竟是要专注于2D画面 还是3D画面呢Should this console focus on 2D graphics or 3D polygons graphics? 正当整个团队还在为这一困境踌躇不前时 一股新的游戏风潮席卷了全日本的街机市场While the team were contemplating this dilemma, a new gaming phenomena was taking over Japanese arcades. 那是一款由世嘉出品的3D游戏 VF战士It was Virtua Fighter, a 3D polygons game by Sega. 在不久之后的1993年The Sony team now had their answer. 索尼终于做出了他们的选择Not long after this in 1993, 索尼成立了SCE 该公司独立于索尼音乐的业务(SCE: 索尼电脑娱乐公司)Sony computer entertainment would be formed out of the CEO of Sony music, 久多良木健任SCE经理and Ken Kutaragi himself. 索尼音乐部的介入反倒使PS项目因祸得福The involvement of Sony music was actually blessing in disguise 这得益于索尼音乐内大量的市场营销人才as the marketing creative talent and manufacturing of the disks, 而且 光碟的制造仅在公司内部即可完成 这省下了大量的时间和金钱could be done in-house, saving both time and money. 次年在东京的一家酒店里 索尼展示了一些技术性的游戏小样The following year in a Tokyo hotel, Sony would showcase some technical demos. 这些在酒店展会里展示的小样 已经足够吸引到那些敏锐的开发商了The technical demo showed in the hotel session, were good enough to open the floodgates for keen developers. 艺电和南梦宫这样的大牌现在也开始对PS产生了兴趣Being players like Electric Arts and Namco were now interested. 那么PS是凭什么吊起了开发商们的胃口呢?So what caused all of this interest? PS拥有优秀的3D画面 但最重要的还是它强大的CD读取机能The PlayStation had solid 3D graphics and most importantly CD capabilities, 这一机能也是它超越现在市面上卡带式游戏机的主要原因which are a major step above present-day cartridges. 1994年12月 PS主机在日本的销量开始小幅度下滑In December of 1994, the PlayStation was light loose in Japan. 它的主要竞争对手是世嘉土星主机Its main competition was the Sega Saturn. 以前从来没有哪一款游戏Never been in a game that allows you to fly. 能让玩家在流畅的实时演算3D画面内自由翱翔Fluent and free in real time 3D. 从来没有Never not anywhere. 特别是在其他的主机系统上But especially not on that other system. 这仅仅是因为 那些主机都只有一个处理器Simply because with only one processor. 仅凭一个处理器无法支撑这样庞大的计算量It doesn’t have the power to do it. 和我一起自由翱翔吧Fly with me. Fly. 未来 现在就来You’re not ready. 世嘉SEGA. 起初两款主机的销量都不错Sells for both console started off strong, 但世嘉土星最终被证明是一款失败之作but despite this the Sega Saturn ultimately proved to be a failure. 主要的原因是 PS不仅卖得更便宜 开发商还更容易为它开发游戏The main reasons being that is the PlayStation sold so cheaper and also much easier to develop for. 这意味着它比世嘉土星有更多的游戏Meaning many more games than the Sega Saturn. PS在1995年于全球上市 人气暴涨A PlayStation worldwide release would occur in 1995 and popularity soared. PS是史上第一个销量突破一亿大关的主机The PlayStation would be the first console to cross 100 million sales, 同时也成为了20世纪九十年代标志性的消费类产品and would going to become an iconic consumer product of the 1990s. PS劲头正盛 其地位就算是64位的任天堂主机也无法撼动Not even a Nintendo 64 could dampen the success of a Sony machine. PS系列的成功很大一部分要归功于它聪明地推出了PS2The PlayStation success are the cleverly titled PlayStation 2 PS2可能是史上最畅销的家用机would be the best selling home console of all time, 全球一共卖出1.55亿套selling 155 million units. 随着时间的推移 相信PS3和PS4也都将成为爆款As time went on, the PlayStation 3 and 4 would both be Smash Hitz, 索尼正以王者的姿态席卷客厅娱乐市场solidfying Sony as a leader in living room entertainment. 这样看来 被任天堂拒绝反倒成为了索尼最好的机遇Being rejected by Nintendo turned out to be the greatest things that happened to Sony. 好的 在本期视频圆满结束之前Alright, so before we wrap up the video, 我们还为屏幕前所有的好奇宝宝们做了一个盘点for all you knowledge seekers out there, 让我们一起来看看初代PS主机的五大有趣事实let’s take a look at five fun facts about the original PlayStation. 第五NUMBER 5 你可曾思考过方块圆圈三角叉号所代表的含义吗Have you ever wondered what the square triangle O and X actually mean? 我们来看看Well, let’s take a look. 三角形代表玩家的视角The triangle represent the pleyers point of view. 方块键象征着一张纸 以及游戏内的文件The square represents a piece of paper for many days and ingame documents. 圆圈代表“是” 叉号代表“否”The O means ‘YES’ and the X means ‘NO’ 最有趣的是 美版主机上的圈叉键是反的But funny enough in western markets this was reversed. 第四NUMBER 4 索尼自主开发的第一个游戏是The first Sony major developed game 汽车大奖赛was Motor Tune Grand Prix 这款游戏由索尼旗下的一个小团队Polly’s开发by a small team called Polly’s. 这个小团队最后成为了鼎鼎大名的Polyphony DigitalAll these will go on to become Polyphony Digital, 也就是GT赛车系列游戏的开发者the creator of the Legendary Grand Turismo series. 第三NUMBER 3 在1994年 南梦宫开发出了一块名为system 11的测试板 用于模拟PS1In 1994, Namco developed a test board called System 11 to simulate the PlayStation 1 during development. 第一个使用该主板的运行的游戏The first major title to use this board 是一款格斗游戏的测试版was a test program for fighting game, 这款游戏被用来测试3D角色建模上的纹理表现情况to experiment with textures on 3D characters. 这个测试版的游戏最后成为了史上最传奇的游戏系列之一This experiment would eventually turn into one of the most lengendary games of all time, 铁拳系列 PS核心作品之一Tekken, a key PlayStation hip. 第二NUMBER 2 PS平台上最畅销的游戏是GT赛车 共卖出1000万套The best selling game on the PlayStation was Gran Turismo shifting over 10 million units. 紧随其后的是最终幻想7This is following by Final Fantasy 7, 生化危机Resident Evil, 铁拳3Tekken 3, 古墓丽影Tomb Raider, 以及袋狼大冒险and Crash Bandicoot. 第一NUMBER 1 那么久多良木健又去哪儿了呢?So what about Ken Kutaragi? 现在他是一家网络服务公司的Today he serves as the president and CEO 总裁和CEOof an internet service company 这家公司的名字是Cyber AI 娱乐有限公司called Cyber AI Entertainment Inc.. 去年 健获得了一项终生成就奖Last year, Ken receive a lifetime-achievement award 在2014年的世界游戏开发者大会上at the 2014 Game Developor Conference. 非常高兴还能看到他奋战在一线Nice to see he is still on stuff. 干的不错 健!Good on you Ken! 最棒的是尽管人们讨厌过健的想法It’s pretty cool that even though people hated Ken’s idea, 尽管他曾被其他公司所背叛and another company betrayed him. 但他仍然没有放弃 最终在现代电子游戏史上留下了浓墨重彩的一笔He still stuck with it, forever changing the course of gaming history. 总之 以上只是为大家介绍科技史的沧海一粟Anyway, that was just a bit of technology history for you. 我希望大家喜欢这个视频I hope you liked this video, and if you did, 如果你喜欢 请为我们点赞并订阅我们的频道give it a thumbs up and subscribe if you need it. 欢迎在评论区和我们一同分享你珍爱的PS记忆Feel free to leave a comment of your favorite PlayStation memory. 我是Bean Dagogo 这里是冷流科技This is Bean Dagogo, you’ve been cold Fusion. 我们下期再见And I’ll see you again soon for the next video. 冷流科技coldFusion 换个姿势看科技 感谢观看It’s new thinking.
  • 2021-08-24超回路列车冷流科技[Music playing] 大家好 欢迎再次收看ColdFusion视频栏目Hi, welcome to another ColdFusion video. 本期节目介绍的是 超回路列车In this video, we’ll take a look at the Hyperloop: 这是种全新的运输方式The brand new method of transport 由企业家及百万富翁埃隆·马斯克提出brought forth by the entreperneur and billionaire Elon Musk. 咱们闲话少说So let’s get straight into it. 首先 它到底是什么?First of all, what is it? 大体上来说 这是第五种运输方式Well, in broad terms, it’s the fifth mode of transport. 截至目前 我们使用过So far, throughout history, we’ve been using 火车…trains… 汽车…cars… 飞机…planes… 船只…boats… 技术上来说 还有火箭and technically rockets. 但我从没坐过 而你也不大可能坐过But I haven’t been in one and you probably haven’t neither. 所以可以忽略不计So that doesn’t really count. 超回路列车将成为第五种运输方式The Hyperloop is going to be the fifth form of transport. 且听我细细道来So going to some more spcific details, 超回路列车是一种高速运输系统the Hyperloop is a high speed transport system 乘客坐在密封的胶囊状列车里in which passengers sit in a pressurised capsule 列车由空气垫托起that rise on a cushion of air. 胶囊列车在密封的 接近真空的环境中运行The capsule operates in a sealed near-vaccum environment. 推进系统将从几个方案中选出The propulsion system is still to be chosen from a number of options. 其中两项是磁悬浮和空气压力2 of which are magnetic levitation or air pressure 后者与空气球台原理类似similar to that of an air hocky table. 采访者:“设计蓝图太复杂了”Interviewer: “The blue prints are pretty complicated.” 埃隆·马斯克:“嗯 蓝图总是有点复杂Elon Musk: ” Well, blue prints are always kind of complicated 我的意思是 对 有数学公式什么的and I mean, yes there is math 哈哈 可真没那么难的”haha, but it’s really not that hard.” 采访者:“听起来还是很复杂啊 埃隆”Interviewer: ” It still sounds pretty complicated, Elon.” 埃隆:“就像是在空气球桌里放个管子Elon: ” It’s like a tube within an air hocky table. 管子里压力较低…it’s just a low presure tube… 里面放进胶囊列车…with a pod in it… 其下部是空气轴承和空气滑板…that runs on air bearings and air skis… 使用…嗯…前部的空气压缩机推进with… um… an air compressor on the front. 空气压缩机吸入列车前部高压空气that’s taking the high pressure air above upon the nose… 然后通过空气滑板排出and pumping it through the air skis. 那真的…That’s really… 我指天发誓 没那么难I swear it’s not that hard. 呵呵…”haha…” 预计该系统平均行进速度The system is proposed to travel at an average speed 为900千米/时 最高达到1220千米/时at 900 km/h and at the top speed of 1220km/h. 埃隆真的没时间做这个Elon really doesn’t have that much time to do this one. 他在忙着造火箭 电动车和供居家使用的电池He’s too busy building rockets, electric cars and betteries to power homes. 所以 他公开了这个点子 然后以竞争的方式So he’s given away this idea and outsourced it 进行外包in the form of competetion. 为争夺该项目 已经成立了几个公司Several companies have formed to take on the project 老式团队 跨学科团队和学生主导团队甚至and even some old style, interdisciplinary, student-led teams 一起合作来推进超回路技术发展are working together to advance the Hyperloop technology. 这些放在后面讲But more on this later. 那么 埃隆·马斯克为什么想做这些?So why does Elon Musk want to do all this? 意义何在?What’s the point? 埃隆:“其实 我想通过超回路列车达到的是Elon: “What I really intend to do with the hyperloop 激发人们对新型运输方式的兴趣was really to spur interest in new forms of transportation. 嗯…我认为 我开始认为Um… and I think, I’m starting to think 这事能成this is really gonna happen. 所以…是的…”So… yeah…” (掌声与欢呼声)[Claps and cheers] “我的意思是 公众和全世界都想要新事物 这再清楚不过“I mean, it’s clear that the public and the world want something new 我觉得在坐的诸位就能办到and I think you guys are gonna bring it to them. 那么 恭喜了!”So, congratulations!” 好了 那他是怎么想到这个主意的?OK, so how does the idea come about? 时间回到2012年Well, back in 2012 埃隆在美国加州圣莫妮卡参加科技博客《潘多日报》的活动Elon was at a PandoDaily event in Santa Monica, California. 在那 他向世界宣布了自己正在考虑There, he announced to the world that he was thinking of 推出第五种运输方式的想法a fifth mode of transport. 下面是现场视频This is that moment. 埃隆:“我想 也许我可以先申请专利 然后Elon: “I think maybe I should patent it and then 将专利开源 提供给任何offer to open source the patent to anyone that can 有实力 能干成的人be credible case that they could actually do it. 嗯… 我们还在讨论Um… since we’re debating it. 但这将是第五种运输方式But it would be for a fifth mode of transports. 我还给它起了名字 叫超回路列车”I have a name for it. It’s Hyperloop.” —采访者: 超回路列车?—埃隆: 正是– interviewer: The hyperloop?- Elon: hyperloop, yeah. 在另一次采访中 埃隆提到Elon states in another interview that 他在一次机场线堵车的过程中提出了雏形概念this initial concept came to him when he was stuck in airline traffic 那次堵车使他参会迟到了一小时which caused him to be one hour late for a meeting. 这些都很有趣So that’s still well and good 但是 咱们看看该系统的优点 以及其可能存在的问题but let’s be aware of some advantages and possible problems with the system. 首先 优点First, the advantages. 理论上 胶囊列车不会坠毁Theoratically, the pods can’t crash. 建造成本也要低很多It’s also much cheaper to build 造价仅相当于计划中加州高铁的十分之一it’s about 1/10 the cost of the proposed California high speed railway system. 也就是说 票价可能只要25美元This means that tickets could cost as little as 25 dollars. 速度也快很多It’s also a lot faster. 基本上 从洛杉矶市中心到旧金山市中心只要30分钟You can basically get from downtown LA to downtown San Francisco in 30 minutes. 从阿姆斯特丹到巴黎也就这么长时间and it would take about the same time to get from Amsterdam to Paris. 小贴士 如果距离比这远些的话Just as a side note, for distances longer than that 其实使用超音速客机会更划算it’s actually more economically viable to use a supersonic jet. 由于使用了太阳能 超回路列车节能性能超强It’s also extremely energy-efficient due to solar power utilization. 事实上 作为封闭的系统 超回路列车能够产生的电能In fact, the hyperloop could generate more power 比消耗的电能要多than it consumes as a closed system. 埃隆:“…因为在这个系统里 你产生的能源要多于消耗的Elon: ” …Because you generate more power than you consume in the system. 嗯… 还有储存电能的方法um… and has a way to store the power 所以这个系统可以一天二十四小时 一周七天地连续运行so that it would run 24\7… 嗯…而不使用电池”um… without using batteries.” 所以 技术上讲 整个系统其实像一部发电机So technically, the whole thing actually acts as a power generator. 好的 下面咱们看看可能出现的问题Ok, so let’s move on to some possible problems. 以下是对超回路列车提出的一些质疑Here’s some thoughts from the critics of hyperloop. 有人认为 乘坐超回路列车的体验会十分惊悚They say that the experience could be frighting 因为乘客们将被置于一个促狭 封闭无窗的胶囊中because passengers would be in a narrow, sealed, windowless capsule 胶囊又处于封闭的隧道里inside a sealed tunnel. 而且 极快的加速和嘈杂的振动 可能导致Also, the fast acceleration and noisy vaberation could cause 晕动病motion sickness. 还有关于装备保障方面的问题 尤其是如何处理There are also legistical questions regarding how to best deal with 设备故障 安全事故和紧急撤离等等equipment mulfunctions, accidents and emergency evacuations. 最后 成本可能高于预期Finally, the cost maybe high than anticipated. 埃隆曾说过 他意识到了这些挑战Elon has stated that he reallizes these challenges 但他相信那些着手处理问题的人 对他们的技术和创新抱有信心but has strong faith in the skills and innovation of those working on the problem. 除此以外 未来在设计上可能也要改进In addition to this, designs could also change in the future for the better. 好的 为了好玩Ok, so just for fun 咱们用拓展的眼光 审视超回路列车的概念let’s take a wide perspective on the concept of the hyperloop. 你可能会很惊讶 类似的想法You maybe surprised to reallize that such an idea is 其实200多年前就有了over 200 years old. 1812年 英国机械工程师 发明家乔治·梅德赫斯特In 1812, British mechanical engineer and inventor George Medhurst 写了一本书 书中详细阐述了他关于在密封管道内 通过空气推进wrote a book detailing his idea of transporting passengers and 运送人员和货物的想法goods through air-tight tubes using air propulsion. 第一个成功投入使用的超回路列车类系统The frist real working application of hyperloop-style transport system 是水晶宫气动铁路was the Crystal Palace pneumatic railway. 1864年 该系统在伦敦三座隧道中运行This operated 3 tunnels in London in 1864 and 由蒸汽机驱动的大型风扇提供动力use large fans that were powered by a steam engine. 关闭之前 该线路事实上成功运行了一年之久The line actually operated successfully for a year before it was close down. 好的 再回到现在Alright, so back to the present day. 咱们看看超回路列车目前有什么进展Let’s look at some current progress of the hyperloop. 现在 人们在内华达州修建了轨道So right now, tracks are being built in Nevada 使工程师得以对系统进行测试 并改进设计方案allowing engineers to test systems and refine their designs. 目前已有三家公司进入融资阶段 以运行超回路列车3 companies have already begun funding rounds to operate the hyperloop. 包括:超回路列车运输技术有限公司They are: Hyperloop Transportation Technologies, Inc. 美国太空探索技术公司SpaceX 超回路列车技术公司and Hyperloop Technologies. 超回路列车运输技术有限公司和超回路列车技术公司Hyperloop Technologies and Hyperloop Transportation Technologies, Inc. 已经与包括中国在内的十国政府进行了洽谈 以在其国内主要主要城市have been talking to 10 governments including China to build hyperloops 搭建超回路列车in their major cities. 还有一些独立公司也进行了模拟和测试There’ve also been other simulations and test done by independent companies. 目的是更好地了解超回路列车的概念Just to see how the concept would be. 比如 有公司使用MATLAB软件和Simlink设计模块集成进行测试For example, MATLAB run a test with Simlink to see 以检验超回路列车在设计中的加州线路表现如何how the hyperloop would perform on the proposed California route. 在此模拟测试中 上方显示的是速度In the simulation, we have speed at the top 乘客舒适度由重力数值测量passenger comfort measured in G force 高度数值在底部and elevation at the bottem. 我们需要关注的是乘客舒适度这一指数Passenger comfort is what we need to keep an eye on here. 说明一下 重力大体上是Just for clarification, G force is basically the measure of 由于运动中方向改变 导致对身体产生拉力的感觉pull on a body due to a change in direction when in motion. 以下仅供参考: 一辆轿车以50千米/时的速度For reference, a car turning a wide corner 通过23米长有弧度的转角with radians of 23 meters at about 50km/h 大概产生0.8个重力pulls about 0.8 Gs. 如你所见As you can see 超回路列车模拟中的乘客舒适度the passenger comfort in the simulation of the hyperloop 基本保持在0.5个重力的范围内stays mostly within the 0.5 region 这是空气垫起到的缓冲作用due to some natural dampening by the air cushion. 所以 这个体验可能很舒服So it actually seems like this idea could be pretty comfortable. 没准跟坐车感觉差不多Maybe no less comfortable than a car in fact. 这当然是从数学上和理论上来说的Mathematically and theoretically speaking anyway, of course. 好了 本期节目接近尾声Alright, so almost at the end of the video. 但还有一点But just one last bit. 咱们再看看超回路列车胶囊车厢竞赛Let’s take a look at the Hyperloop pod competition. 咱们神侃这档 不少学生和非学生团队A number of student and none-student teams are 正在参加超回路列车胶囊车厢竞赛paticipating in a Hyperloop pod competition right now as we speak. 2015年6月Back in June, 2015 美国太空探索技术公司宣布 将资助超回路列车胶囊车厢设计竞赛SpaceX announced that they would sponser a Hyperloop pod design competition. 一个月后Just one month later 超过700个团队提交了申请more than 700 teams have submited applications. 2016年1月In January of 2016 超过120个学生工程师团队被挑选出来 提交最终的设计方案more than 120 student egineering teams were selected to submite final design pacages. 2016年中旬In mid 2016 其中至少22支队伍将在加州的测试轨道上at least 22 of them will build hardware to compete 建造硬件设施 以参加竞赛on a test track in California. 我真的认为 这是年轻工程师I really think this is an amasing opportunity for young engineers 发明家和设计师的绝佳机会 他们可以开动脑筋inventors and designers to really get their minds working 以己之力 改变历史on something that could change history. 真是激动人心It’s encouraging to see. 看起来 超回路列车这种概念The Hyperloop seems to be a concept that could 可能为中距旅行带来革命性变化revolutionize medium distance travel. 但更重要的是 把点子 设计及人才But further more, the actual concept of outsourcing 进行外包和公开流动的概念and openly floating ideas, designs and talents 是基础设施领域内is an amazing new way to innovate and do business 的一种颠覆性的创新和商业模式within the infrastructure sector. 与该领域现状的剧烈偏离也令人振奋The violent shift-away from the status quo is also really exciting. 以后 我们要对该领域紧密关注We just have to watch this space closely in the future. 好吧 本期节目到此结束 感谢收看Anyway, that’s the end of the

  • 2021-08-24通用电气公司有多大?您正在收看的是冷流科技You are watching ColdFusion TV 冷流科技[Music playing] 大家好 欢迎再次收看ColdFusion视频栏目Hi,welcome to another ColdFusion video. 通用电气General Electric 是全球最大 最具盛名的多元综合性大企业之一one of the largest and well- known multinational conglomerates 其产业涉及医药 航空from medicine and aviation 能源及厨房电器等多个方面to energy and kitchen appliances 可以说it’s safe to say that 他们将企业做的很大they do a fair bit 但是这个公司是怎么起步的呢but how did the company begin and 它到底有多大呢just how big is it 它背后经历了怎样的故事and what about the deeper story GE有没有一些公开的秘密are there any other lesson- known secrets 是我们应该知道的呢?that we should know about General Electric 让我们开始吧let’s begin 序幕Prelude “说实话 你必须了解通用电气美妙的组合 不然你都不知道自己错过了什么“and honestly you don’t know what you’ve been missing until you get this wonderful GE combination 我们确实we did 拥有带有独立门的冷冻部分we did it have this separate freezing section with a separate door 及其所拥有的独立冷冻系统”and freezing system on its own” General ElectricGeneral Electric 或称GEor GE 是托马斯·爱迪生于1889年所建立的was founded by Thomas Edison in 1889 当时他所建立的大公司涉及到多方面的发展when he emerged many businesses into just one corporation 这些都是在摩根·大通和he did this with the help of J.P.Morgan 安东尼·德雷克赛尔的帮助下实现的and Anthony Drexel 众所周知as we all know 爱迪生发明了很多东西Edison did a lot of great things 但仅仅用了几项措施but by at least a few measures 爱迪生并不是一个好人Edison wasn’t a nice guy 1880年 他欺骗了尼古拉·特斯拉he cheated Nikola Tesla in the 1880s 并试图通过极端的方式and sought to destroy Tesla’s progress 破坏特斯拉所取得的成就by many desperate means 包括电死当地的宠物including the electrocution of local pets 但这一切都出现在他采取这种方式之后but that’s all coming up on this channel a bit later 这是下一期的内容and is a story for another day 如果你想观看 请自己订阅subscribe if you want to see that 无论如何anyway 虽然爱迪生犯了错误despite Edison’s misbehavior 但在1886年in the 1886 在新一期的GE was one of the first twelve companies 道克琼斯指数榜单上listed on the newly formed 美国通用电气公司成为十二大公司之一Dow Jones Industrial Average 一百二十年之后after a hundred and twenty years GE是原十二个公司中they’re the only one of the twelve original companies 唯一还在榜单上的公司still listed on the index 1900年年初in the early 1900s GE是第一个the company was one of the first 进入语音广播这个新行业的公司之一to enter the new business a voice radio broadcasting 除此之外还有美国无线电公司out of which came Radio Corporation America 或称RCAor RCA 它是20世纪规模较大的公司a massive company of the 20th century “今天晚上电视里播放的没我们想看的“nothing we want to watch on TV tonight 但是我们依旧用RCA视频光盘播放器but we’re still going to watch something great 和视频光盘with our RCA video disc player 观看一些优秀的节目and video discs 仅仅需要一个开关just with the switch 我们就能看到一部好电影we’re watching a great movie 您正在RCA视频播放器上and you’re watching us 收看我们的节目video disc on RCA 而同时also around this time GE也是第一个引进电烤箱GE was the company that would introduce the first electric toasters 轻便电炉and hot plates 以及家庭烹饪变革的公司and many revolution for home cooking 公司成立三十周年时in the thirties 出现了经济危机the company was responded to the great depression 公司便引进GE消费金融by introducing GE consumer finance 因此 消费者可以so customers could pay for the new appliances 分期付款over time 人们认为 1930年到1940年之间it was the nineteen thirties and forties GE才真正开始创新 如发明了日光灯that’s thought GE actually innovations like the fluorescent lamp 和第一台商业用途的导航仪and the first autopilot for commercial applications 有趣的是interestingly enough 1950年 GE成为世界上第一个拥有电脑的公司in the 1950s GE was the first business in the world to own a computer 拥有着除美国政府之外的and there were the largest user of computers 最多的电脑用户outside of the US government 在那之后after this GE开始生产自己的电脑主机GE started manufacturing their own mainframe computers 甚至自己的操作系统and even their own operating system 到1996年 除了IBM和Honeywell公司之外alongside companies like IBM and Honeywell GE是八大电脑公司之一GE was exactly one of the major eight computer companies of the 1960s 然而这样的时代在1970年就结束了this era came to end in the 1970s GE公司把他们的计算机部门卖给了Honeywell公司when they sold their computer division to Honeywell 整个20世纪throughout the 20th century GE发展了多方面的领域GE expanded to many fields 其中就有能源方面one of which was energy 2002年and in 2002 安然公司倒闭后 GE公司从安然公司获得了风能的股份the company acquired wind power assets from Enron when they went to bankrupt 事实证明as it turns out 安然公司的风能在当时是美国唯一幸存的大型风力涡轮机制造商Enron wind was the only surviving US manufacturer of large wind turbines at the time 从20世纪末到by the end of the 20th century 21世纪初and the start of the 21th century GE成为全球的商业巨头GE was a true global giant 并家喻户晓and a household name 今天Present day 今天today 就收入方面来说General Electric is now ranked No.24 in the fortune 500 GE在财富500强中排名第24位in terms of revenue 我们来看一下它的实际规模let’s take a look at some aspects of its actual size GE拥有305,000名员工 工资总计1460亿General Electric has three hundred and five thousand employees with the revenue of a hundred forty six 身价超过六千五百亿billion and over six hundred and fifty billion dollars worth of assets 超过瑞典和挪威的that’s more than the GDP of Sweden 国内生产总值or Norway 也是or 新加坡国内生产总值的两倍two times the GDP of Singapore 在福布斯全球最有价值的商标榜单中排行第九the company is also listed as No.9 on the Forbes world’s most valuable brand list 好吧 这一切都很好ok, so that’s all very nice 但是他们所有的钱是怎么赚来的呢?but how do they make all their money? 好吧 我来告诉你们well I’ll tell you 但在我们了解之前but before we get to that 我会告诉你们一些事情I’m gonna ask you something 你认为什么是GE公司最大的赚钱能手呢what do you think is GE’s biggest money maker 傻瓜都知道that’s no- brainer 是能源是吗?it’s energy right? 好吧well 并不是no 我们来看看最近三年GE的收入图表let’s take a look at this three- year chart of GE’s revenue 你可以看到as you can see 他们的收入中最大的一部分其实来自于金融their largest segment is actually finance 占了31%at 31% 从个人信用卡到能源相关金融服务this is anything from personal lines in credit cards 这就是所有的内容to energy related financial services 有趣的是an interesting fact 在资金市场中within the capital markets 就市场占有率而言in terms of market share 他们几乎是摩根大通公司they’re about half that of JPMorgan chase 美国银行bank of America 和花旗集团的一半or Citigroup 这很重要and that is significant 因为自1990年because those three banks are actually the result 这三所银行就成为of a merge of 28 banks 28所银行的合体since 1990 因此 我们所不能用小成就来衡量GE所取得的进步so there’s no small feat to measure up to GE的第二大部分便是the next big segment for General Electric 能源和水资源is power and water 占18%at 18% 这其中包括煤气 风能this includes gas wind 蒸汽涡轮机and steam turbines 核反应堆nuclear reactors 太阳能solar power 发电机and generators 第三大部分占14%next up at fourteen percent 是航空制造方面的is aviation 比如航空系统和服务so these are things like aviation services and systems 商业和军事引擎and commercial and military engines 第四大部分是占12%the next segment at 12% 是健康医疗中心is health care 即磁共振波谱this is MRS CT扫描仪 CT scanners X射线 外科手术和分子机器X- rays and surgical and molecular imagine machines GE在医疗装备业市场上占了39%GE takes out about 39% of the medical equipment industry in terms of market share 那么石油和煤气呢?so what about oil and gas? 令人惊奇的是surprisingly 石油和煤气the oil and gas sector only 仅仅占makes up GE收入10% of GE’s 的10%income 因此 除了上述所有so aside from all of this GE也生产其他产品 比如冰箱GE also makes some other things such as refrigerators 冷藏器freezes 电热炉具和煤气灶electric and gas ranges 炉灶面 洗碗机 烘干机cooktops dish washers dryers 微波炉 都是由这种想法衍生而来的microwaves any get the idea 不好的一面the dark side 我们要转变一下画风so we’re going to change things a little bit here 事实证明as it turns out GE并不是一直都这么成功it’s not all roles for GE 在它的发展历史中 确实有这么一段时间there were certain times in their history that 它们并不被看作是创新的黄金案例之一they were not seen as one of the golden case of innovation 问题在于GE公司的活动细节the problems lie within the details of GE’s activities that 并不是很方便地被展示出来或者被公布到网上aren’t conveniently displayed or listed on their website 曾经有一段时间there was actually a time 世界人民联合起来抵抗GE公司when the people of the world came together and rallied against General Electric 我们来看一下当时的情况let’s see the story 核武器:GE与人民nuclear weapons:GE VS The people 那一年是1984年the year is 1984 美国GE公司比其他大公司多生产了两套核武器系统and in the US GE produced more parts two more major nuclear weapon systems than any other corporation 同时他们还将核武器推广到政府they also promoted nuclear weapons to the government 当时很少有人记得总统few people actually remember the existing tie between the president at the time 与GE的公司的关系and General Electric 要知道you see 罗纳德·里根在成为总统之前其实是Ronald Reagan was actually a spokesman for General Electric GE公司的官方发言人before he became president “对于GE公司来说“for General Electric 这就是罗纳德·里根here is Ronald Reagan 要告诉他们的bringing 道理:a General Electric 进步是最重要的产品”progress is our most important product” 克勒·路易利埃如是说Kelle Louaillier 他建立了“企业问责”国际组织founded a group called Corporate Accountability International 专门阻止GE公司生产核武器for the sole reason of stopping GE from producing nuclear weapons 1984年that the same year in 1984 克勒的团队组织了一次国际基层运动Kelle’s group organized an international grassroots campaign 包括讲述GE公司背后的真相的including a 40 nationwide film 40部国产电影explaining the truth behind GE’s corporate image “GE公司“General Electric is in this 从事核武器的生产business of building weapons 是为了获取利润而不是因为爱国 也不是为了国家for profit not for patriotism not for the country not for the flag 只是为了赚取利润”but for profit 这场战役包括联合抵制GE公司的产品the campaign also included a boycott of all General Electric products 这项活动the kickoff of the project 有一个良好的开端got off to a strong start 但是接下来呢?but would it work 1989年in 1989 抵制活动开始后的三年three years into the boycott 全面战役后的五年and five years into the overall campaign GE公司花费了GE spent 比原来四倍还多的价钱在品牌广告上 以保护其four times more on brand advertising to defend its brand image that 在过去的四年里建立的品牌形象in the past four years combined 战争the fight 开始了was on 到1990年by 1990 美国有四百万人联合抵制GE公司four million people in the United States aligned were boycotted GE 而且战役活动已经扩散到加拿大and campaign activities have actually spread across Canada 以及西欧地区and into West Europe 一些规模大的零售商店用别的公司所生产的灯泡取代major retail stores replace GE light bulbs GE公司所生产的灯泡with those made by other companies 1993年四月in the April of 1993 抵制活动进行了七年后after seven- year boycotting 人们最终战胜了the people had finally won GE公司General Electric 使其停止了核武器的生产 completed its move out of the nuclear weapons business GE公司称这是一个商业决定stating that it was a business decision 这次抵制活动使得GE公司仅仅在医疗装备的销售上the boycott has cost GE over 50 million dollars 就损失了五千万美元in lost medical equipment sales alone 1984年战役开始的时候when the campaign began in 1984 五万个核弹头不断发出警告 美国50 thousand nuclear warheads were on constant alert and the US was building 每天要制造五个核炸弹five nuclear bombs per day 战役快结束的时候at the close of the campaign GE公司再也没有投入生产核炸弹no more nuclear bombs were in production by General Electric 但这还不是全部but that’s not all GE公司陷入更深的危机之中the dark side for GE goes deeper still 情况变得更糟糕了 尤其是对于美国人and it gets worse especially for Americans 1986年in 1986 GE收购了美国广播公司GE purchased NBC 仅仅在1989年这一年之间during just one year in 1989 GE公司在与海湾战争后停止使用的系统相关的General Electric had received close to two billion dollars in military contracts 军事合同上就赚了二十亿related to systems that end up being used in the Gulf War 当然and of course GE公司一位神秘的人在用武器帮助美国政府GE unknown stranger was helping the US government with weapons 美国投入广岛和the bombs dropped on Nagasaki 长崎的导弹and Hiroshima 在GE的帮助下were researched 也得到研究and developed 和发展with the help of GE 因此so 事实证明as it turned out NBC的母公司在海湾战争时期NBC’s parent company 就设计designed 制造manufactured 每个重要的核武器系统and supplied parts for every major weapon system 并为其提供零件during the Gulf War 其中包括战斧this includes the Tomahawk 巡航导弹cruise missiles 以及隐形轰炸机系统and systems for the stealth bomber 和B-52型轰炸机and B-52 bomber 因此实际上so in reality 金融奖励制度是错误的the financial incentives were driving the wrong way 当NBC的记者和财务顾问when correspondent and paid consultant of NBC television 对需要GE生产的装备的美国武器praised the performance of US weapons 大加赞赏时that were commanding the equipment made by GE 这个大公司the corporation that 就需要支付他们的工资了paid their salaries 1991年 在海湾战争的催化下in the heat of the Gulf War in 1991 退休的将军和商船队队长成为战争时期NBC节目的常客retired generals and admirals became regulars on NBC shows during the war time 他们越是向人们灌输战争的必要性the more they told people war with needed 人民对战争的抵制就越少the less resistance the public had towards war 当然 这对于GE来说就意味着以合同的形式this of course meant more money for GE 赚取更多的钱in the form of contracts 而其中的一部分钱a share of which 便到了那些上将的口袋中ended up back in the pockets of those same generals 这样的事依旧持续着this kind of thing continued 13年后13 years later 也就是2004年in 2004 GE公司在军费开支中仍占有大量的股份the company still had a big stake in military spending meaning 这意味着NBC报道阿富汗战争that NBC is reporting of the Afghanistan war 动力并不纯may have also been tainted 那么这一切为什么会发生呢so why do all of this 好吧well 一只导弹价值一百万with a single missile costing over 1 million dollars to make 在战争中有成千上万个导弹发射and with tens of thousands of missiles being fired in a conflict 你就能想到这场战争带来的利润有多大you can only image how profitable war can be 这真是糟糕透了it really sucks that this happened 但是尽管如此 这一历史篇章终究以积极的结尾收场but this chapter does end on a positive night though 2013年 GE公司将NBC出售给了康卡斯特in 2013 General Electric sold NBC to Comcast 这当然是一个完美的结果which of course still is an ideal 同时也使GE从利益冲突中but it’s still a relief 解脱出来from that conflict of interest 我也很高兴那些结论and I’m glad that no longer exists 再也不会存在conclusions 那么 我们能做些什么so what can we make of all this 好吧 我们自己了解到GE是一个大公司well we’ve learned that General Electric is a huge company 其发展涉及到多方面的领域and has its hands in many fields 但令人喜忧参半的是but it’s a bit of a mixed bag GE曾做了很多令人不可置信的事GE has done some incredible things in the history 在多方面的领域都有创新and have innovated in many fields 但是他们的黑历史but the dark parts of their past 不能被忽略can’t be ignored 但是为了but to end this 以另一种方式收场on the plus side 尽管还有美国政府最大的国防承包商之一的存在even though there’s still one of the US government’s biggest defense contractors 他们也不会在制造武器了they no longer build weapons 在这个领域内 他们所做的就只是生产制造引擎and it’s mainly just engine manufacturing that they do in that field 好了 这段视频马上就要结束了so I guess that runs out the video 感谢您的观看thanks for watching guys 如果你喜欢它 不要忘记点个赞don’t

  • 2021-08-24【三星NOTE7电池爆炸门】对三星意味着什么您正在欢迎收看的是冷流科技You are watching ColdfusTion TV. 冷流科技[Music playing] 大家好 欢迎再次观看ColdFusion视频栏目Hi, welcome to another ColdFusion video. 在这次节目中我将要和大家聊一些关于三星Note 7的事So in this video I’m just gonna be talking to you a bit about the Note 7 以及最近它的电池爆炸门and the recent exploding battery debacle. 在这之前 Note7被看作是一款精良之作The Note 7 was supposed to be a story of refinement. 历经一年的研发实验和调试The moment when years of experimentation, trail and error 这一刻这款集完美尺寸性能和外观之大成的大屏直板手机面市seems converge on the perfect size function and form for large screen phone tablet. 三星火力全开只为让这款产品在市场热卖Samsung’s marketing campaign engine was faring also on this only have the product 却因为电池问题被投诉they were selling burns to flames when they were charging due to the batterie effect 随着iPhone7的发布 ,恰恰此时With the iPhone 7 release, just around the corner, 三星陷入了困境,情况不能再糟了this couldn’t have come for a worse time for Samsung Mobile. 接连的爆炸不是因为手机充电线 The exploding phones weren’t due to the faulty charging cables, 而是电池设备本身it was the faulty devices themselves. 一位来自澳大利亚珀斯的男士就因为自己的Note7爆炸 One man from Perth Australia had his Note 7 explode, 毁掉了酒店的床单和地板charring his hotel room bed sheets and carpets. 酒店向他要叫近两千美元损失费 The hotel charged him almost 2 thousand dollars for damages 而三星公司同意支付赔偿and Samsung agreed to pay. 三星针对电池爆炸问题发表了一些声明 Samsung has issued some statements on the problem 同时发布了召回和暂停销售的通知as well as issuing a recall and temporary holding of sales 根据报告所说 三星公司设计了Note7的电池模组 According to reports, Samsung designed the Galaxy Note 7 battery cell 但生产却授权给了第三方公司but the production was delegated to third parties. 据称 其中一家电池生产商It’s claimed that one of these third-party manufacturers 负责生产电池模组中的四十个小部件has produced the battery present in 40 units. 技术细节还未公布 但或许电池生产商承担部分召回费用 The technical details haven’t been released yet but perhaps it’s fair 也是理所应当的事that the battery manufacturer takes on some of the cost of the recall 这笔费用不会便宜,我们稍后会说及此事and that’s not going to be cheap. We’ll talk about the cost later. 接下来的声明来自三星的发言人The following is a statement from a Samsung spokesperson. 声明称 从9月1日开始 三星服务中心登记的来自国内外投诉共有35起Quote:” As of Sept. 1, a total of 5 claims were registered with Samsung’s service centres at home and abroad. 1百万台里面只有24台受电池问题影响Only 24 units on a scale of 1 million were affected by the battery problem. 出于客户安全至上的考虑 我们已经决定停止Galaxy Note7出售By putting our top priority on customer safety, we’ve decided to halt sales of Galaxy Note 7 并且给所有用Note7的手机用户提供新机替换and offer new replacement handsets to all customers.” 声明表示 已经售出两百五十万台Galaxy Note7 In quote, it said that 2.5 million Galaxy Note 7 handsets 现在所有这些都要因为电池爆炸问题被召回as a part of this exploding battery fault. 那么 这对三星来说意味着什么呢?So, what does this mean for Samsung? 当被问到召回成本对公司的影响When asked about the recall’s financial impact on the company, 三星手机事业部负责人高东真说 这将是一个让人心碎的数字 并称Samsung’s Mobile chief, Codan Jin, said it would be a heartbreaking amount, and quote, 根据一些分析家估计 两百五十万台手机召回以及换新将花费三星至少十亿美元“The recall and phone replacement to 2.5 million Note owners is set to cost Samsung at least 1 billion dollars by some analysts’ estimates.” 尽管这个数字听起来很多 但对于三星 While this sounds like a lot, for Samsung, 这只占到公司2016年净利润的5%that only represents about 5% of the firm’s net income for 2016. 结果虽然不是三星想要的 但也不会是这家公司的末日Not ideal but not the end of the road for the company either. 然而 这次事件的代价不只是损失Note7 However, the cost is not only in lost infantry, 三星的市场价值和客户信心也将受到冲击their market value and consumer confidence would also take a hit. 投资者担心 在电池爆炸新闻后 三星股价可能会下降Investor concerns saw the share price drop in reaction to the news. 电池爆炸新闻第一次发布时三星还未回应 Samsung’s marketshare initially drop by 7 billion dollars 股票便一下子缩水70亿美元when the news was first announced before regaining some ground, 这种易变性被认为是当今投机市场极度焦躁的表现that being said this kind of volatility is expected as the speculative markets of today are extremely twitchy. 前面谈及的所有内容都未包含同行竞争这块Overall mentioned hasn’t included the competition. 即使没有耳机插孔 但苹果7传言有3G内存 和相比Note7Even would have no headphone jack and the iPhone 7 rumour 快25%的处理器以及更大的存储容量选择to have 3 gigabytes of ram and a 25% faster CPU as well as larger storage options 都将帮助苹果赢得三星丢失的潜在市场份额will take advantage of some of the lost potential Samsung sales. 这一切情况对苹果来说都是天赐良机The whole scenario could just be a blessing for Apple. 总而言之 即使是第三方生产商的过错 So in conclusion, even though this is a third-party manufacturer’s fault, Note7仍然是三星公司的手机it’s still a Samsung branded phone 三星公司在开售前的生产质量控制阶段 就应该做好所有的性能测试and they should have tested all of these during the quality control phase of production before actually selling the product. 正如问题早期突显的样子As highlighted earlier, 顾客信心受到了损害 而且我个人认为许多规避风险的顾客consumer confidence will be damaged. And I personally can’t imagine many risk-adverse type of individuals. 也不会再购买Galaxy Note7,即便电池缺陷已经解决Staying away from the Note 7 even when the problem has been fixed. 由于顾客牢记这次事件 三星在今年圣诞节的销量将会受到影响Depending on consumers’ memory, this could hurt Samsung while in Christmas sales. 总的来说 尽管类似的事件有发生在其它手机生产商All in all, although similar kind of things that happened to other phone manufacturers, 这是迄今为止三星手机遇到的最糟糕的一次事故 this is the worst thing yet to happened to Samsung Mobile 并将花费公司至少几个月来挽回and will take at least a few months for the dust to clear. 那么 这些就是我对Note7经历惨败的想法So, yeah, those are my thoughts on the Note 7 fiasco. 有朋友让我做一个调查分析,这就是了I’ve had a few people asked me to cover it so I just thought I’d give my thoughts. 感谢收看这个短片 如果有兴趣就订阅这个栏目吧Thanks for watching this quick video.

  • 2021-08-24诺基亚的沉浮part1您正在收看的是冷流科技You are watching ColdfusTion TV. 诺基亚——崛起与陨落Nokia – The Rise And Fall 序言(第一部分)Prelude(Part 1 of 3) 诺基亚NOKIA 是人们最为广泛认可的公司之一One of the most widely recognized, 和一些公司一样 都曾使地球的面貌焕然一新and on average,universally like companies ever to grace the face of this earth. 当我说出NOKIA这个名字时 你们可能第一时间会想到手机When i say the name of NOKIA,you may think of a phone. 但是你也可能会想一些更加抽象、更加深刻的东西But you may also think of something a bit more abstract and deeper than that. 它可能会让你想到那些更明朗的时代或者一些美好的记忆It may remind you a brighter times or fond memories. 我最开始用的手机就是诺基亚My very first phone was NOKIA. 我相信你们之中的大多数也一样And this may be the case of many of you guys. 诺基亚是一个运行从来没出过错的公司NOKIA was a company that could do no wrong 直到……当然 他们最终还是倒闭了Until..Of course,they eventually did. 那么这家公司背后的故事是怎么样的呢?So what’s the story behind this company? 为什么一个公司能如此成功And how could a company so successful? 具有如此大的影响力和开拓精神So influential and so pioneering, 而产生裂缝的原因便是它想要回归过去模式Split between the cracks,to become a show of what once was. 倒闭之前 诺基亚公司变成了微软公司的一个翻版Before eventually it evaporating into the shadow of Microsoft 从诺基亚这个例子我们能学到很多重要的东西The lessons learned from NOKIA could teach us something important. 让我们开始吧Let’s begin. 诺基亚公司的起源要追溯到1856年NOKIA’s history dated back to 1865 一个采矿工程师 Frederick IdestamOne mining engineer——Frederick Idestam 在芬兰南部建立了他的第一个木浆工厂set up his first wood pulp mill in southern Finland. 几年后 他又在 Nokianvirta河流沿岸开设了第二家木浆工厂A few years later,he opened the second mill on the banks of the Nokianvirta River. 而“诺基亚”这个名字正是来源于这条河流This river inspired him to name his company——NOKIA. 我觉得这挺有趣I think that’s kind of interesting.. 因为他不知道这个名字的由来有多么的宽泛Because he would have no idea how wide did he recognize this name would become. 很快 诺基亚就扩展到其他领域Soon NOKIA expanded into other industries 比如橡胶 电缆 轮胎 电视such as rubbers,cables,tires,TVs, 靴子等等boots and more. 因此 可以肯定的是 早期的诺基亚公司与我们现在所知道的是完全不同的So safe to say,that the early NOKIA was a completely different company to the one that we knew in love. 不介意的话 听我来讲述诺基亚是怎么变成我们现在所认识的一个公司的Without a mind,listen me what to when NOKIA became the NOKIA we actually know today. 我们从1960年讲起We pick up the story in 1960s. 那时候 一些伟大的事物引领着世界At this time,those great deal guiding the world. 社会 政治以及新的思维方式Social,political,and new ways of thinking. 我们在很多地方都取得了较快的发展We gained momentum in diverse places. 但是当这一切都被打破后 就会是一个不吉利的征兆But over shattering all of this,was something particularly ominous. 比如冷战The cold war. 1956年至1960年期间 矛盾还没到僵化的地步In the mid – to – late 1960s,the conflict wasn’t so icecold, 这时核战争也随时可能发生And nuclear war was actually a possibility. 共产主义超级大国苏联正在测试他们的导弹The communist superpower the USSR was testing their bombs. 而坚定的资本主义国家—美国And the steadfast capitalist USA, 也在测试他们的导弹was testing their bombs. 这两个大国之间的交涉越来越凶猛Both of these parties were texting with increasing ferocity. 两国之间的紧张关系令全世界感到紧张These tensions made the whole world nervous. 连极其中立的国家芬兰也感受到了这种紧张的氛围The tension to have felt even in the rather neutral country of Finland. 因此他们就采取行动And they were taking action. 做最坏的打算They were preparing for the worst. 芬兰政府欲将军事调查研究融入到无线电话通信中去The Finnish gorvornment wanted to millitary research into radio telephone communications. 为了帮助芬兰挖掘出可靠的军事通信所具有的潜能To help their country realize the full potential of reliable millitary communication. 一个名为“诺基亚”的小公司拿到了与芬兰政府的合同A little company called NOKIA got the contract. 从专业发展通信From the expertise developing communication, 到后来的民用无线电车电话网络later developed into a civilian radio car telephone network 这样的转变使得整个国家在七十年代风格大变that span the whole country by the style of 1970s. 以今天的标准来看 这种系统很落后 因为它需要轮番发言The system was very primitive by today’s standards because it actually have to take turns to speak. 但是诺基亚真正的繁荣实在1980年的时候But the real boom and started from NOKIA began in the 1980s. 那个时候大规模生产才开始出现When mass production took place. 诺基亚公司开始扩展到大规模生产的生产方法之中The company began to expand into mass production methods of manufacturing. 这种由人类添加的经济模式成本低 规模小 价格便宜The economy of scale men added features less cost and smaller size and cheaper price. 诺基亚公司开发将他们50%的产品都开发出来The company explored the 50% of their product, 并于1985年将其扩大到全球范围内and expanded globally by 1985. 最终这家芬兰公司与Tandy合作 给美国以沉重打击The Finnish company finally hit the big time. 获得巨大成功When they hit the USA by teaming up with Tandy. 在此期间 移动手机这个概念所带来的效果是不可置信的During this time,the concept of mobile phone was incredible. 你不需要为打一个电话而将钱投入机器中去You don’t have to slope money into machine to make a call. 你不用排队等电话You don’t have to wait in the payphone line. 你也不用在家等着别人的电缆再稍微伸长一点And you didn’t have to be at home,hoping the cable can stretch just that a little bit longer. “任何地点 任何时间”就是其宗旨‘Anywhere,anytime’ was the idea. 这样一来 很快便形成了大规模市场The vast of the market was soon realized 当时的销量预计会超过3000%When sells exceeded predictions by 3000% 只能说人们喜欢交谈It just saying that people like to talk. 而诺基亚刚好满足了这一要求And NOKIA may have been onto something here. 据说诺基亚在80年代末的成功的秘诀就是It said that the secret of NOKIA’s success in late 1980s, 拥有应对手机产业中不同市场的能力was the ability to tailor to different market in the mobile industry. 而同时又努力地发展多个产业While keeping the efforts going in various other industries. 1987年In 1987 诺基亚公司创造了“the mobiler cityman”NOKIA created ‘the mobiler cityman’. 这是首部能制作新闻头条的诺基亚手机It was the first NOKIA phone to make major news headlinds. 由于米切尔提出将垃圾粉碎著称俄罗斯方块式建筑Due to the fact that Mitchell garbage of 当时苏维埃的领导人the leader of the Soviet Union at the time. 被曝在新闻发布会上使用诺基亚手机was spoted using the phone during press comforters. “cityman”这个标志与那些渴望独立的人有着直接的关系The slogan for the city man was straight connection for those who need independent. 但是1988年到1989年期间诺基亚卖的并不是很顺利But it was’t all smooth sailing and in 1988 to 1989 此时诺基亚公司出现了危机NOKIA found herself in a crisis. 要知道 当时苏维埃政府已经倒塌了You see, at this time the Soviet Union collapsed. 欧洲经济出现很大的退步And there’s a major recession in Europe. 因此诺基亚对产品的多样性要求似乎在一夜之间就消失殆尽了So the deman from NOKIA’s diverse later product seemed to dry up over night. 由于这些原因 那些善变的管理人员和Because of these,those changing management and Jorma Ollila 前花旗银行家约玛·奥利拉A former citybank banker 于1992年接管了CA公司came to take over CA in 1992, 作为一名银行家 约玛·奥利拉设立了两个管理人员As a banker,Jorma Ollila think of two about management. 他做了一个能决定公司未来十五年发展羽翼的决定Here he made the one decision that would shape the company’s feather for the next decade and a half. 他决定切断公司所有额外的收益 将注意力集中在手机上He decided to shut off all the company ‘s extra proceeds and focus directly on mobiles. 这些都是在诺基亚的黄金时代—Ushering in NOKIA’S golden period—— 九十年代时期所盛传的the 1990s. 在这十年里 诺基亚真的超越了其他人This is the decade that NOKIA truely left everyone else in the dust. 成为历史上当之无愧的发展最快的产业Fill the undisputed champion of one of the fastest growing industries in history. 话虽这么说 但这是只是第一部分And with that being said,that’s only part 1 of the series. 感谢您的收看

  • 2021-08-24Li-Fi光照上网技术您正在收看的是冷流科技You are watching ColdFusion TV. 冷流科技[Music playing] 大家好 欢迎再次收看ColdFusion视频栏目Hi,welcome to another ColdFusion video. 自1992年澳大利亚射电天文学家Since WiFi’s accidental invention in 1992 约翰 • 奥沙利文博士通过探测爆发迷你黑洞by Australian radio-astronomer Dr John O’Sullivan 的失败试验偶然发明了WiFi之后through a failed experiment to detect exploding mini black holes. WiFi就对数字通讯产生了革命性的影响WiFi has revolutionized digital communication. 如果没有WiFi 我们现在的移动生活将是另一番光景Without it, our current mobile way of life would be some what different. 目前 WiFi承担了全球互联网流量的60%WiFi currently makes up 60% of global internet traffic. 即便如此 WiFi还是有很多短板With all of that being said, WiFi still has some issues. 其信号强弱不定It sketches at times with varying signal 安全性也存疑 因为你的信号and it’s not totally secure because your signal 能穿墙 可以轻易为他人获取could travel through walls and be easily picked up by someone else. 这都是因为WiFiThe reason for all of this is that WiFi 使用无线电波传输数据use its radio wave to transmit data. 那么 我们怎么才能改进这项技术 解决上述问题呢?So how do we improve this technology and solve these problems? 我们必须使用价格低廉…We must use something that’s cheap… 安全可靠…safe… 随手可得…plantiful… 传输速率更高的数据传输手段and more robust for data transfer. 答案是…The answer… 光light. 光是一种完美的介质 因为它实际上是Light is perfect because it’s actually just part of 电磁频谱的一部分 和无线电一样the electron magnetic spectrum just like radio waves. 但频率要高很多But at much higher frequency. 也就是说 携带能量的光波That is, the wave that carry the energy 传播速度比无线电波要快得多cycle at much faster rate the radio waves. 光波的带宽比无线电波宽一万倍以上Light also has a requency range 10,000 times greater than radio waves 最高达到790太赫兹going up to 790 THz 而无线电波最高只能达到300吉赫兹versus a maximum of 300GHz for radio waves. 以上所述 充分说明光波有能力All this means that light has the capacity to transmit 能比无线电波在更短时间里传输更多的数据vastly more pulse of data in much less time than radio waves. 将光波用于互联网数据传输介质的概念The concept of light being used as a medium to transfer internet data 被称作LiFihas been coined LiFi. 咱们听听LiFi的发明人 哈罗德·哈斯Let’s hear a bit more from Harald Haas, the founder of LiFi 在2011年一场TED讲座中的发言 那时这项技术才刚刚出现不久in a TED talk from 2011, right at the technology’s infancy. 哈斯: “…我们早就安装了灯泡。 也就是说 基本设施业已存在Haas: ” …light bulbs installed already. So we have the infrastructure there. 看看天花板 你能看见好多灯泡Look at the ceiling, you see all these light bulbs. 我们可以使用这些灯泡进行通讯吗?Can we use them for communications? 我们唯一要做的是 就是把And one thing we need to do is we have to replace 那些低效的白炽灯these inefficient incandescent light bulbs 荧光灯灯泡 换成新的LED(译注:发光二极管)技术 LED灯泡florescent lights, with this new technology of LED, LED light bulbs. LED是半导体 是一种电子器件An LED is a semiconductor. It’s an electronic device. 它有一种非常灵敏的特性And it has a very nice acute property. 其强度可以极高的速度进行调节Its intensity can be modulated at very high speeds 可以极高的速度开合and it can be switched off at very high speeds. 这也正是我们在这项技术中利用的最基本的特性“。And this is a fundamental basic property that we exploit with our technology. “ 该技术原理又是什么呢?So how does this all work? 哈斯: ”大家都知道遥控器有红外线LEDHaas: “You all know remote controls have an infrared LED 简单来说 就是当你打开LED灯泡basically you switch on the LED 如果灯泡关了也就关机了and if it’s off, you switch it off. 灯泡会发射简单低速的数据流 大概是10000到And it creates a simple, low-speed data stream in 10,000 bits per second 20000比特/秒。这可没法用来看油管的视频20,000 bits per second. Not usable for a YouTube video. 我们所做的是…What we have done is we have… 开发了这么一项技术 我们并不只传输developed a technology with which we transmit with our technology 单一的数据流 而是以更高的速度并行not only a single data stream, we transmit thousands of data streams 传输成千的数据流“。in parallel, at even higher speeds. “ 在演讲的其他部分In another part of the talk, 哈斯进行了一次相当酷炫的展示Haas does a pretty cool demonstration. 他给一盏台灯装上了价值约3美元的LED灯泡He fits a desk lamp with a normal LED bulb worth about 3 dollars. 通过软件编码控制灯泡以极高的速度闪烁A software code makes the bulb flicker at extremely speeds. 这些闪光 或者说脉冲 随即被接收器转化成信号This flickering or pulsing is then converted into a signal by receiver. 看看接下来发生了什么And then watch what happens next. 哈斯: ”我打开灯又会发生什么呢?”Haas: “So what happens when I switch on that light?” 哈斯:”正如你看到的 这是一盏灯 台灯Haas: “As you would expect, it’s a light, a desk lamp 摆上书 你就能阅读。它能照亮空间Put your book beneath it and you can read. It’s illuminating the space. 但同时 你能看见上面的视频But at the same time, you see this video coming up here. 这段高清视频 就是通过光线传播的And that’s a video, a high-definition video that is transmitted through that light beam. 各位肯定心里嘀咕。 你们想 呵呵You’re critical. You think, Ha, ha, ha. 这不过是自作聪明的学者搞的把戏This is a smart academic doing a little bit of tricks here. 但是下面我要这样…But let me do this… 【掌声】[Claps] 哈斯:“同样的 是这束光Haas: ” Once again, it is this light that transmits 用分立的数据流传输了这段视频this high-definition video in a split stream. 如果你看看这束光 它照常起到照明的作用And if you look at the light, it is illuminating as you would expect. 但各位的肉眼是觉察不到的You don’t notice with your human eye. 人眼发现不了这个灯泡强度上You don’t notice the subtle changes in the amplitude that we 的细微变化。 它依然起到照明的作用impress onto this light bulb. It’s serving the purpose of illumination 但同时 我们也有能力传数据but at the same time, we are able to transmit this data. 如你所见 天花板上的光线也照到这里的接收器了And you see, even light from the ceiling comes down here to the receiver. 但并不产生影响It can ignore that constant light 因为接收器只对细微变化起反应。”because all the receiver’s interested in are subtle changes. “ 哈罗德希望将这项技术整合到手机Harald hopes to integrate this receive technology into phones and 甚至手机摄像头上 这样它们可以even phone cameras so that they can send and receive 以光为媒介 收发高比特率的信息high bite rate information through and from light. 你可能在想 要接受数据You maybe wandering if the light has to be turned on the whole time 是不是需要一直开灯to receive data. 哈斯表示确实如此,但我们Haas says yes, but the thing is you can 可以把灯光调暗actually dim the light down 这样人眼不会发觉还有光线so the human eye can not detect that it’s on 但接收器还能工作but the receiver still can read it. 好了 听起来不错是吧OK, so that sounds great. 但现实生活中 这管用吗?But does it actually work in real life? 答案是肯定的The answer is yes. 在实验室环境下 研究人员将LiFi的速度提高到10GB/秒Research has reached speeds of 10GB/S in lab conditions. 作为对比 韩国有世界最快的网速For perspective, South Korea’s world record internet speeds 也只达到100MB/秒are only 100MB/S. LiFi在商业环境下也进行了成功的试验LiFi has also been successfully tested in a commercial contest. 在爱沙尼亚一间办公室进行的试验中There’s been trials in offices in Estonia that 信息传输速度据说达到了1GB/秒reporting transmission speed of 1GB/S. 依然比目前的平均WiFi速度快了100倍Still 100 times faster than current average WiFi speeds. 设想一下 你可以随便走进一个房间So imagine this, you can walk into any room 打开灯 然后同时就可以上网swich on the light and simultaneously, instantly have internet connection 速度比平时使用的WiFi快一百倍100 times faster than your regular WiFi. 还不止这些But it doesn’t stop there. 牛津大学的研究人员发布了有关Researchers of the Oxford University have published results of 可见光互联网速度达到223GB/秒的研究成果visible light internet at 223 GB/S. 以这样的速度 你可以在一秒内下载18部1.5GB大小的电影With those speeds, you can download 18 1.5GB movies in one second. 当然 服务器是否有能力But of course, whether or not the server 将文件传输给你would be able to serve those files to you 就得另当别论了it’s another story entirely. 但这依然是十分惊人的成就But still very impressive none the less. 结论是什么呢?So what’s the conclusion here? 廉价的光驱动互联网 或者是LiFi可能随处可见We could be seeing very cheap light powered internet or LiFi everywhere. 这也许意味着物联网也将成为现实This could easily lead to the interent things becoming reality 在这种条件下 所有电子设备都能互相通讯a situation where all electronic devices communicate with each other. 你的手机可以和电冰箱通讯from your mobile phone communicating with your fridge 桥梁上的传感器to sensors on a bridge 可以把结构损伤和潜在风险的警告告知土木工程师warning of structural damage and potential failure to civil engineers. 如果LiFi得以大规模应用If LiFi becomes widely available 我相信它能掀起一场技术革命I believe it would have turned the corner into a technological revolution 将世界变成一个普通用户可以轻松接入互联网that would lead to a world where the internet and 和进行信息传递的地方transfer of information is no longer an obstacle for the average user. 总之 这就是我想带给诸位So anyway, that was just the quick story 看官的简短故事I thought I’ll bring to you. 这是件新鲜事 因为就在视频录制的2天前It’s quite fresh, because the LiFi test in real life scenario LiFi才刚刚完成了第一次实测were only completed two days ago, at the time of this recording. 真是令人振奋啊So pretty exciting stuff. 感谢收看Thanks for watching. 喜欢的话请点赞Don’t forget to leave a thumbs up if you like it. 也可以留言和订阅Comment, subscribe if you need. 如果想了解更多的前沿技术发展If you want to know more stuff in cutting edge technology 请再看十秒 遵循屏幕上的指示hung around for the next 10 seconds and follow the prompts in screen. 安啦 小伙伴们! 我是大哥哥Cheers, guys!
