襄阳手术治疗早泄的费用要花多少钱襄阳市第一人民医院下午几点上班襄阳哪家医院治疗睾丸炎好 Hey,Vsauce,Micheal here.And what if every single person on earth jumped at the exact same time?Could it cause an earthquake?Or would we not even be able to tell? Well,first things first,lets talk about the earths rotation.The earths spins since why we have night and day,and it spins quickly.At the equator,the earth is spinning at more than 1000 miles per hour.嘿 欢迎来到Vsauce 我是Michael。如果地球上的每一个人在同一时刻起跳,会发生什么?会引起一场地震吗?还是连我们自己都不知道?好,先说重要的,我们先来谈谈地球的自转。地球自转产生昼夜,并且速度还很快。在赤道 地球以1000英里/小时的速度转动。Now a spinning ice-skater can speed up by moving mass closer to the center.And the earth is no different.In fact,if you get down on the ground right now,and move your mass closer to earths center,technically,you will speed up earths rotation making this day shorter.Now,the change that you would make to the earths rotation is way smaller than we can even measure.But its calculatable and the impact can be quite impressive when you talk about redistributing more mass than just one person.眼下一个转动的溜冰者能将质量靠近质心以提高转速。而地球却没什么不同。实际上 如果你现在倒在地上,然后将你自己靠近地心,严格意义上来说,你会加速地球自转 从而把一天变短。此时,你对地球自转造成的变化远小于我们能够测量的精度。但这是可计算的,它的影响也是很可观的,当讨论重新分布远大于一个人的质量时。For instance,last year,the earthquake in Japan.redistributed so much of earths mass towards the earths center.that everyday,since than,has been 1.8 micro-seconds shorter.But that was a giant geological event.What can us humans do to the earth all on our own? I mean,there are more than 7 billion of us now.What if we all got together in one place and jumped? What would that even look like?例如,去年发生在日本的地震,将如此多的质量分布到距离地心更近的地方。以至于自从那时 地球自转比原来慢了1.8微妙。但那是一个巨大的地质现象。我们人类全凭自己,能对地球做什么呢?我的意思是,我们有70亿人口。如果我们全部聚集在一起,跳一跳会怎么样?那看起来会是什么样子?Interestingly,if you took the entire human population of earth,and had them all live in one place with the same density that people live in New York City.you could fit everyone all of us,into the state of Texas.But thats living,not standing around in the crowd which is how we would probably wanna do to jump.If every single person alive right now on earth stood shoulder to shoulder,you could fit all of us into the city of Los Angeles.It would be an incredible sight to be hold,A mere 500 square miles containing every single on earth.有趣的是,如果你将地球上的所有人聚集起来,让他们都以纽约城的人口密度住在一起,一个德克萨斯州大小的地方就可以容纳所有人类。但这是居住 不是一群人站在一起,那样我们才可能跳起来。如果每个活着的人现在肩并肩站着,一个洛杉矶大小的地方就能容纳所有人类。那将是一个令人难以置信的景象,一片只有500平方英里的土地,容纳地球上的每一个人。OK,so then we jump,what happens?Unfortunately,not much.I mean,we are all awesome people here on earth.But our collective mass compared to the mass of the entire earth,its like nothing.In fact,DOT PHYSICS calculating that if all of us were to get together in one location and all jump 30cm into the air at the exact same time,we would push the earth away from us a tiny amount.Earth would only move away from us about 1/100 of the width of a single Hydrogen atom.And heres another thing,because we are all jumping and then going back to where we started,earth is just going to move back to where it started.好, 然后我们起跳,会发生什么呢?不幸的是,似乎没啥。我的意思是,我们都是地球上令人敬畏的人类啊。但是我们大家的质量与地球的相比,就像是什么都没有。事实上,DOT PHYSICS 计算出如果我们所有人聚集在一起,同时向上跳30厘米,我们会将地球推力我们一丁点儿。地球只会大约远离我们百分之一氢原子的宽度。另外,因为我们全都起跳 然后回到原点,地球也会移动到原来的位置。So,our big jump wont be able to change earths position in space.But come on,7 billion people all jumping together.thats gotta be able to cause some sort of seismic activity,right? So lets say you have a lot of people altogether at one place,and you have them all jump on one,two,three.Did you feel that?Well,the B did this with 50,000 people and discovered that a kilometer and a half away,it only registered as a point six on the Richter scale,You would meet 7 million times more people than even live on earth right now to jump at once to recreate the earthquake that recently happend in Japan.So,even though we were all awesome,compared to the size of the earth,we are not much.所以我们这一跳不会在空间上改变地球的位置。但怎么会呢,70 亿人一起跳啊,一定会导致某种地震活动,对不对?所以比方说,你同时有很多人,然后你让他们都起跳 一,二,三。你能感受到吗?B找了五万人做这个实验,然后发现1.5公里之外,之测量到里氏0.6级的地震 你要有现在地球人口,七百万倍的人,同时起跳来重现最近发生在日本的地震。所以, 即使我们再厉害,比起地球的大小,我们也没有多少。But dont get too discouraged,our collective jump will contain a lot of energy,THE STARIGHT DOPE calculated that even if only the people who lived in China got together and jumped,their jump would be equivalent of 500 tons of TNT.Of course,500 tons of TNT doesnt do much to an earth,that weights 6 Sextillion 588 Quintillion tons.To make yourself feel more powerful,pick a card.Ive got 10 of them here,lets say,you choose this one.Boom,congratulations,we have just decimated this deck of cards.但是别感到太沮丧,我们大家的跳跃会包含许多能量,THE STRAIGHT DOPE 计算出即使只有全中国的人聚在一起 然后起跳,它的能量相当于500号TNT爆炸时释放的能量。当然 500吨TNT对于地球来说算不上什么,地球重达6.588x10^21吨。为了让你变得更强大 挑一张卡。我这有10张卡 比如说 让你选这一张。砰 恭喜 我们刚刚从十张卡片里面抽走了一张。Why,well,because technically decimate does not mean obliterate completely.Deci,10,it means to take away one tenth of something.So the next time you take a quiz,and dont do so well on it,you only get 10%.Well,sure thats an F.But,by getting 10% of them right,you decimated that quiz.And since weve been talking about crowds,lets talk about Youtube crowds.Youtube audiences that if you count that you see the bottom of every ,And get some perspective on it,well began with Dunbars Number.Its an estimation of the maximum number of people we can have stable social relationships with at an given moment.为什么?因为严格意义上来说“decimate”不是完全抹杀的意思。“deci”10 它的意思是某物的十分之一。那么当你下次做小测验并且考砸了,你只拿到10分 当然 毫无疑问是个F.但是 因为你做对了10%所以你在10题中就对了1道。既然我们一直在讨论人群 来说说Yotube上的看客吧。Yotube看客们 如果你们能看到每个视频底下的信息 稍加观察的话,那么我们先从邓巴数开始说起吧。这是我们在某个时间内能够维系稳定社会关系的最大人数。And its based on the size of our Neocortex.These arent just acquaintances,these are people you have social contact with.A network where you know how everyone relates to everyone else.And the number is usually given to be somewhere between 100 and 230.Which means that when a Youtube receives more than 230 views from different people more people have seen that that you could ever realistically hope to know well at a given moment.If a has more than 100,000 views from different people,more people have seen that than you will ever meet in your life.它与我们大脑的新皮质有关。这些并非仅仅相识的人,而是你能与之进行社会交往的人。一个你对人与人之间关系了如指掌的网络。这个数字大约在100到230人之间。这也就意味着 当一个Youtube视频观看人数超过了230,观看视频的人数就比你希望能在一段时间内熟识的人数多了。如果一个视频被超过10万不同的人观看,那么观看视频的人数就比你一生中能够遇到的人多了。And by meet,I mean shake hands with,learn their name,talk to them for a bit.I mean think of it this way,you and me,we are only statistically expected to live around 28,470 days.So even if you are to meet someone,two three people everyday of your life including when you are a baby.you still wouldnt meet as many people as have seen that Youtube with 100,000 views.遇到,在这里指的是你们二者握手 互留姓名 二人间聊聊天。我的意思是 从这个方面思考 你我之间,统计意义上说我们的寿命只有大约28,470天。那么如果你要见某些人,即使每天遇到两三个人 把婴儿时期的那几年也算上,你遇见的人数还是超不过观看这段视频的那100,000名Youtube观众。Keep this in mind,even though you or even a large group of us can do much to change the earths location or rotation.we can affect it a little bit.Newtons Third Law guarantees this,if you weigh 150 pounds,the earth is pulling you down with a force of 150 pounds.But you are also pulling up on the earth with a force of 150 pounds.If you fall 3 meters,the earth is pulled you down 3 meters,but you have also exerted an equal and opposite force on the earth.Of course its a lot bigger.SO if you fall 3 meters,you pull the earth up about a billionth of the width of a proton.which aint bad.请记住,即使是你 或者是我们一大群人能够为改变地球的自转或位置做出许多事,我们能在极轻微程度上产生影响。牛顿第三定律向我们保 如果你的体重是150磅,那么地球就是对你施加一个向下的,大小为150牛的力。但是你也对地球施加一个向上的,大小为150牛的力。如果你下降3米 就是说地球把你向下拉3米,但你也对地球施加了一个大小相等,方向相反的力。当然这个看上去大多了。如果你下落3米 地球就被你拉上来了质子直径十亿分之一垢距离。似乎还不错。So the next time you move your body,the next time you jump,Felicia,think about this:you just affected the earth as much as it affected you.You got that kind of power,speed of power.You all should go check out GEEK amp; SUNDRY,Felicias new channel,its one of my new favorite names.And,as always,THANKS FOR WATCHING.那么,当你下次移动身体,Felicia 当你下次跳起来的时候,想想这件事:你对地球的作用和地球对你的作用相当。你的确有那种能力 那么大的功率。你也应该去瞧瞧GEEK amp; SUNDRY Felicia 的新频道,这是我现在最近爱上的频道之一。另外 还是和往常一样,谢谢观看。201503/364351栏目简介:《造物小百科How it’s made》介绍了许多东西的制作或者说发明方法,非常实用。其中的英语视频发音地道,内容浅显易懂,过程形象生动,是提高英语听力水平,积累英语知识和一些简单生活常识的好素材。201509/391976襄阳市铁路医院盆腔炎多少钱
