MichaelRubinstein_2014X-_看到不可见的运动，听到沉默的声音。酷？令人毛骨悚然？我们不能决定_
So over the past few centuries, microscopes have revolutionized our world. 过去的几个世纪,显微镜改变了世界。
microscopes:n.[光]显微镜(microscope的复数); revolutionized:adj.革命化的;被彻底改革的;v.彻底改革(revolutionize的过去式);
They revealed to us a tiny world of objects, life and structures that are too small for us to see with our naked eyes. 它揭示了肉眼难以看到的 物体,生命和结构的微观世界。
revealed:v.揭示;显示;露出;(reveal的过去分词和过去式) structures:n.结构; v.建造(structure的第三人称单数形式); naked:adj.裸体的;无装饰的;无证据的;直率的;
They are a tremendous contribution to science and technology . 它对科技进步做出了巨大的贡献。
tremendous:adj.极大的,巨大的;惊人的;极好的; contribution:n.捐款;捐资;定期缴款;贡献;促成作用;稿件; technology:n.技术;工艺;术语;
Today I'd like to introduce you to a new type of microscope, a microscope for changes. 今天我要向您介绍一类新型显微镜, 观察变化的显微镜。
It doesn't use optics like a regular microscope to make small objects bigger, but instead it uses a video camera and image processing to reveal to us the tiniest motions and color changes in objects and people, changes that are impossible for us to see with our naked eyes. 它不是通常所说的光学显微镜 可以放大微小物体, 它利用视频摄像机和图像处理 来揭示物体和人的微小的颜色和运动变化, 这些变化是光凭肉眼难以分辨的。
optics:n.[光]光学; video camera:n.摄像机; processing:v.加工;处理;审核;数据处理;v.列队行进;缓缓前进;(process的现在分词)
And it lets us look at our world in a completely new way. 它可以让我们以全新角度看世界。
So what do I mean by color changes? 我所说的颜色变化是什么意思呢？
Our skin, for example, changes its color very slightly when the blood flows under it. 举例来说,我们的皮肤,当血液流动时 皮肤表面的颜色有微弱变化。
slightly:adv.些微地,轻微地;纤细地;
That change is incredibly subtle , which is why, when you look at other people, when you look at the person sitting next to you, you don't see their skin or their face changing color. 变化十分微小, 小到当你观察坐在 你身边的人的时候, 你不能看到他脸上皮肤的颜色变化。
incredibly:adv.难以置信地;非常地; subtle:adj.微妙的;精细的;敏感的;狡猾的;稀薄的;
When we look at this video of Steve here, it appears to us like a static picture, but once we look at this video through our new, special microscope, suddenly we see a completely different image. 我们看看史蒂夫的这段视频,看上去好像是静态图片, 但是一旦我们通过我们新的、特别的显微镜看这段视频, 我们会看到完全不同的影像。
static:adj.静止的; n.[物]静电(干扰);
What you see here are small changes in the color of Steve's skin, magnified 100 times so that they become visible . 您在这里看到的是史蒂夫皮肤颜色微小变化 放大100倍之后的肉眼可见的效果。
magnified:v.放大;扩大;增强;夸大;夸张;(magnify的过去分词和过去式) visible:adj.明显的;看得见的;现有的;可得到的;n.可见物;进出口贸易中的有形项目;
We can actually see a human pulse . 我们可以明确的看到人体的脉搏。
pulse:n.脉冲;脉搏;脉率;强劲的音乐节拍;v.搏动;跳动;震动;洋溢着;
We can see how fast Steve's heart is beating, but we can also see the actual way that the blood flows in his face. 我们可以看到史蒂夫心脏跳动得多快, 我们还可以明确地看到血液是如何流经史蒂夫脸部的。
And we can do that not just to visualize the pulse, but also to actually recover our heart rates, and measure our heart rates. 我们不仅可以看到脉搏, 还可以推测心跳速率, 得到我们心跳速率。
visualize:vt.形象,形象化;想像,设想;vi.显现;
And we can do it with regular cameras and without touching the patients . 我们可以通过常用摄像机,不需碰触病人就可以实现。
patients:n.接受治疗者,病人;(patient的复数)
So here you see the pulse and heart rate we extracted from a neonatal baby from a video we took with a regular DSLR camera, and the heart rate measurement we get is as accurate as the one you'd get with a standard monitor in a hospital. 这里您可以看到我们提取的新生儿宝宝的脉搏和心跳速率 这是从常规数码单反相机视频中提取的, 我们测出的心率 和医院监测器测出的一样精确。
extracted:adj.萃取的;引出的;v.提取(extract的过去式及过去分词); neonatal:adj.新生的;初生的; measurement:n.测量;度量;长度; accurate:adj.精确的; standard:n.标准;水准;旗;度量衡标准;adj.标准的;合规格的;公认为优秀的;
And it doesn't even have to be a video we recorded. 而且我们的软件甚至不需要我们自己专门拍摄的视频。
We can do it essentially with other videos as well. 我们可以对其他视频作同样处理。
essentially:adv.本质上;本来;
So I just took a short clip from " Batman Begins" here just to show Christian Bale's pulse. 这是我截取《蝙蝠侠:侠影之谜》（Batman Begins）的一小段片断 显示演员克里斯蒂安·贝尔（Christian Bale）的脉搏。
clip:v.剪辑;修剪;削减;固定;n.夹;夹子;速度;钳; Batman:n.勤务兵;传令兵;蝙蝠侠;
(Laughter) （笑声）
And you know, presumably he's wearing makeup , the lighting here is kind of challenging, but still, just from the video, we're able to extract his pulse and show it quite well. 你知道,他应该是化了妆了, 灯光也是挑战, 但是我们同样从这段视频中提取到了他的脉搏 演示效果不错。
presumably:adv.大概;推测起来;可假定; makeup:n.化妆品;组成;补充;补考;
So how do we do all that? 我们是如何做到的呢？
We basically analyze the changes in the light that are recorded at every pixel in the video over time, and then we crank up those changes. 首先我们分析了录像中每个像素 的光线随时间发生的变化, 我们放大这些变化。
basically:adv.主要地,基本上; analyze:v.对…进行分析,分解(等于analyse); pixel:n.象素;图像的基本单位;表示显示在萤幕上的一点; crank:n.曲柄;奇想;adj.易怒的;vt.装曲柄;
We make them bigger so that we can see them. 经过放大使我们肉眼可以看见这些变化。
The tricky part is that those signals, those changes that we're after, are extremely subtle, so we have to be very careful when you try to separate them from noise that always exists in videos. 棘手的部分是,那些信号, 那些我们要放大的信号十分微小, 所以我们必须把它们和视频中存在的噪音 区分出来。
tricky:adj.难办的;难对付的;狡猾的;诡计多端的; extremely:adv.非常,极其;极端地;
So we use some clever image processing techniques to get a very accurate measurement of the color at each pixel in the video, and then the way the color changes over time, and then we amplify those changes. 所以我们应用了一些聪明的影像处理技巧 精确的测量每个像素中的颜色, 然后得出颜色随时间的变化, 再然后我们放大这些变化。
techniques:n.技巧;技艺;工艺;技术;(technique的复数) amplify:vt.放大,扩大;增强;详述;vi.详述;
We make them bigger to create those types of enhanced videos, or magnified videos, that actually show us those changes. 我们可以放大这些变化,增强视频、或放大视频, 这样就可以演示出变化。
enhanced:adj.加强的;增大的;v.提高;加强(enhance的过去分词);
But it turns out we can do that not just to show tiny changes in color, but also tiny motions, and that's because the light that gets recorded in our cameras 事实上,我们不仅可以展示颜色的细小变化, 同样也可以展示微小的运动, 这是因为我们的摄像机
will change not only if the color of the object changes, but also if the object moves. 不仅记录物体的颜色变化, 同样也记录了物体的运动。
So this is my daughter when she was about two months old. 这是我女儿,那时她才两个月大。
It's a video I recorded about three years ago. 这是我三年前拍的。
And as new parents, we all want to make sure our babies are healthy, that they're breathing, that they're alive, of course. 作为初为人父母,我们要确保孩子的健康, 当然是,确保呼吸,确保活着。
So I too got one of those baby monitors so that I could see my daughter when she was asleep. 所以我也买了个婴儿监控器 这也我可以在她睡着时看到她。
And this is pretty much what you'll see with a standard baby monitor. 这是标准婴儿监控器所看到的。
You can see the baby's sleeping, but there's not too much information there. 您可以看到孩子睡着了,但没有其他信息了。
There's not too much we can see. 我们看不到更多东西。
Wouldn't it be better, or more informative , or more useful, if instead we could look at the view like this. 可不可以更好点儿,有更多信息,更有用, 就像这样。
informative:adj.教育性的,有益的;情报的;见闻广博的;
So here I took the motions and I magnified them 30 times, and then I could clearly see that my daughter was indeed alive and breathing. 这里我放大了运动30倍, 这样我就可以真切地看到我女儿还活着,在呼吸。
(Laughter) （笑声）
Here is a side-by-side comparison . 这是效果对比。
side-by-side:adj.并肩的;并行的; comparison:n.比较;对比;相比;
So again, in the source video, in the original video, there's not too much we can see, but once we magnify the motions, the breathing becomes much more visible. 同样,在原始视频上, 我们看不到什么, 但是一旦我放大了运动,呼吸变得肉眼可见了 。
source:n.来源;水源;原始资料; original:n.原件;原作;原物;原型;adj.原始的;最初的;独创的;新颖的; magnify:vt.放大;赞美;夸大;vi.放大;有放大能力;

And that's actually my eye, and again this video was taken right after my daughter was born, so you can see I wasn't getting too much sleep. (Laughter) 这实际上是我的眼睛, 同样,这段视频拍摄于我女儿出生不久之后, 所以你可以看到我睡得不多。（血丝）（笑声）
Even when a person is sitting still, there's a lot of information we can extract about their breathing patterns, small facial expressions . 即使当人在静止坐着, 我们也可以提取许多信息 如呼吸节律,面部表情微小变化。
facial:adj.面部的,表面的;脸的,面部用的;n.美容,美颜;脸部按摩; expressions:表达,表情(expression的复数)
Maybe we could use those motions to tell us something about our thoughts or our emotions . 也许这可以 告诉我们,我们的想法或情绪。
emotions:n.强烈的感情;激情;情感;(emotion的复数)
We can also magnify small mechanical movements, like vibrations in engines, that can help engineers detect and diagnose machinery problems, or see how our buildings and structures sway in the wind and react to forces. 我们同样也可以方法微小的机械运动, 如引擎的震动, 这可以帮助工程师诊断机械问题, 或者看到建筑或结构的随风摇动。

Those are all things that our society knows how to measure in various ways, but measuring those motions is one thing, and actually seeing those motions as they happen is a whole different thing. 我们知道这些变化可以通过其他方法测量, 但是测量是一回事, 肉眼看到的又是 另一回事。
And ever since we discovered this new technology, we made our code available online so that others could use and experiment with it. 自从我们开发者这项新技术, 我们便把代码放到了网上,这样其他人可以使用试验它。
It's very simple to use. 用起来很简单。
It can work on your own videos. 可以处理你自己拍的视频。
Our collaborators at Quanta Research even created this nice website where you can upload your videos and process them online, so even if you don't have any experience in computer science or programming, you can still very easily experiment with this new microscope. 我们的合作伙伴,量研科技(Quanta Research),甚至建了个网站 这里可以上传视频并在线处理, 这样即使你没有计算机科学或编程经验 也可以试验这种新型“显微镜”。

We just provided this new tool, a new way to look at the world, and then people find other interesting, new and creative ways of using it. 我们只是提供了新工具,一种看世界的新方法, 然后人们就找到其他有意思、新的创造性地方法使用这个工具。
provided:conj.假如; v.提供; (provide的过去分词和过去式) creative:adj.创造性的;
But we didn't stop there. 我们不满足于此。
This tool not only allows us to look at the world in a new way, it also redefines what we can do and pushes the limits of what we can do with our cameras. 这个工具不仅使我们有了看世界的新方法, 同样它还重新定义了 摄像机的功能限制。
redefines:v.重新定义(redefine的第三人称单数形式);
So as scientists, we started wondering, what other types of physical phenomena produce tiny motions that we could now use our cameras to measure? 作为科学家,我们开始思考, 其他物理现象造成的微小振动 现在我们可以用摄像机来测量？

Sound, as we all know, is basically changes in air pressure that travel through the air. 声音,我们知道 声音是一种压力波,依靠空气的压缩变化在空气中传播。
Those pressure waves hit objects and they create small vibrations in them, which is how we hear and how we record sound. 压力波碰到物体,就会引起物体本身的微小震动。 这就是我们听到了录音的原理。
But it turns out that sound also produces visual motions. 这样,声音也会造成物体的视觉运动。
Those are motions that are not visible to us but are visible to a camera with the right processing. 这些运动,肉眼难于分辨 但是通过处理摄像机却可见。

humming:v.哼(曲子);发嗡嗡声;活跃;繁忙;(hum的现在分词)
Again, if you stare at that video, there's not too much you'll be able to see, but once we magnify the motions 100 times, we can see all the motions and ripples in the neck that are involved in producing the sound. 如果您盯着视频看的话, 仅凭肉眼您是看不出什么端倪的, 但是当我把运动方法100倍后我们就可以看到颈部的运动和波纹 这是由于声音震动造成的。

Testing, testing, one two three.
Mary had a little lamb whose fleece was white as snow, and everywhere that Mary went, the lamb was sure to go.
MR: And now, 137 years later, we're able to get sound in pretty much similar quality but by just watching objects vibrate to sound with cameras, and we can even do that when the camera is 15 feet away from the object, behind soundproof glass. 迈克尔·鲁宾斯坦:137年过去了, 我们可以重构出同样质量的声音 却是通过观察摄像机拍摄的物体振动实现的, 我们甚至可以把摄像机 放到15英尺外隔音玻璃后边。
