SDcamps•演辩营全国英语演讲与辩论赛
And we actually, in this case, I'm sorry to say, it happened — it was serendipitous. 实际上在这件事情上，我很遗憾地说，我们找到了，是偶然间发现的。 Because I got a phone call from our chief chemist and he said, 我接到我们的一位首席化学家打来电话，他说， look, I've just found this such a beautiful reaction, that even if this compound doesn't smell of coumari...
Here's how shape works in normal receptors. 这里展示的是形状是如何对通常的感受器起作用的。 You have a molecule coming in, it gets into the protein, which is schematic here, 一个分子进来，进到蛋白质里，图中所示意的就是蛋白质， and it causes this thing to switch, to turn, to move in some way by binding in certain parts. 通过合并某些部分，它让这个东西转变、旋转向某个方向移...
So I went searching when I started in this game to convince myself that there was any degree of plausibility to this whole crazy story. 在这个游戏的最初，我就开始寻找说服我自己，这个理论有一定的合理性，这整个故事有点疯狂。 I went searching for a type of molecule, any molecule, that would have that vibration and that — the obvious prediction was that it should absolutel...
And this brings me to my modest proposal. I think that bad PowerPoint presentations are a serious threat to the global economy. 下面我就谈谈我的小小建议。我认为，用幻灯片做的那些糟糕的报告是全球经济的严重威胁。 Now it does depend on how you measure it, of course, but one estimate has put the drain at 250 million dollars per day. 当然，这要取决于你如何衡量这件事，但是一种估算...
Now, while the smell wafts over you, let me tell you the history of an idea. 现在，趁着香味还萦绕在你们周围，我来为你们介绍一个想法形成的过程。 Everything that you're smelling in here is made up of atoms that come from what I call the Upper East Side of the periodic table — a nice, safe neighborhood. 现在你所闻到的都是由这样一些原子组成的，他们来自被我称为元素周期...
And…but…but…we have to go a little beyond that. 我们需要进一步深入。 Now let me explain why vibrational theory has some sort of interest in it. 现在我来解释为什么震动理论有一定的道理。 These molecules, as you saw in the beginning, the building blocks had springs connecting them to each other. 这些分子正如你们开始时看到的是基本组成，它们之间有弹簧连接着。 In...
And every single part of this mechanism is actually plausible in biology. 实际上，这个机制的每一个步骤在生物领域中都是可行的。 In other words, I've taken off-the-shelf components, and I've made a spectroscope. 换句话讲，我用现成的部件做成了一个分光镜。 What's nice about this idea, if you have a philosophical bent of mind, is that then it tells you that the nose, ...
Now, the idea is not as crazy as it sounds. 其实，这个想法并不像听起来那么恐怖。 I started a contest four years ago called Dance Your Ph.D. Instead of explaining their research with words, scientists have to explain it with dance. 四年前，我创办了一场比赛，叫“舞动博士”。科学家不能用语言来解释他们的研究，而必须用舞蹈来解释。 Now surprisingly, it seems to work. Dance really ca...
OK, great, we smell vibrations. How? All right? 好吧，我们闻到的是震动。怎么闻到呢？ Now when people ask this kind of question, they neglect something, which is that physicists are really clever, unlike biologists. 当人们问这个问题的时候，他们忽略了一些事情，物理学家都是很聪明的，不像生物学家。 And the two of them…this is a joke. I'm a biologist, OK? So it's a ...
Now, coumarin is a very common thing, a material, in fragrance which is derived from a bean that comes from South America. 香豆素是香水中一个十分平常的原料，从来自南美的豆子中提炼出来的。 And it is the classic synthetic aroma chemical, OK? 是一种经典的合成香料。 It's the molecule that has made men's fragrances smell the way they do since 1881, to be exact. 是男性香水...
The fragrance that you will smell, you will never be able to smell this way again. 一会你们将闻到一款香水，它会带给你们绝无仅有的体验。 It's a fragrance called Beyond Paradise, which you can find in any store in the nation. 这款香水叫做“霓采天堂”，在全国各大商场都能买到。 Except here it's been split up in parts by Estée Lauder and by the perfumer who did it, Calice B...
Now if you use the right kind of atoms and you get them cold enough, something truly bizarre happens. 如果使用正确的原子，并让其足够冷却，奇迹就会发生。 It's no longer a solid, a liquid or a gas. It enters a new state of matter called a superfluid. 这些原子不再属于固体、液体或气体。这些原子进入一种新的物质状态，叫做超流体。 The atoms lose their individual identity, and t...
This smells of cut grass. Now, this is the skeleton of the molecule. 它闻起来就像割下来青草。这就是分子的骨架。 If you dress it up with atoms, hydrogen atoms — that's what it looks like when you have it on your computer — but actually it's sort of more like this, 如果再给它配上其他原子，比如说氢原子，在电脑上模拟看上去是这样，但实际上看上去是这样的， in t...
Good afternoon. 下午好。 As you're all aware, we face difficult economic times. I come to you with a modest proposal for easing the financial burden. 众所周知，我们正处经济困难时期。今天我带来了一个小小的建议可以消除财政负担。 This idea came to me while talking to a physicist friend of mine at MIT. 这个想法来自我和麻省理工学院一个朋友的谈话，他是物理学家。 He was struggl...
However, I managed to get a hold of a Borane eventually, and here is the beast. 无论如何，我最终得到了一些硼烷，这就是那个“怪物”。 And it really does have the same — if you calculate, if you measure the vibrational frequencies, they are the same as S-H. 结果和我预期的一样–如果你计算，如果你计算振动频率，它的和S-H的一样。 Now, does it smell of sulfur? 现在，来看看...
I shall now, therefore, humbly propose my own thoughts, which I hope will not be liable to the least objection. 所以，今天我谨提出我的观点，希望不会遭到反对。 Once we eliminate public funding for the artists, let's put them back to work by using them instead of PowerPoint. 一旦我们消除对艺术家的资金支持，他们可以重返工作岗位让他们取代幻灯片。 As a test case, I propose we...
OK? Now, we're dealing with people who only want results, and this is the commercial world. 今天，我们在和只在乎结果的人们打交道，这是一个商业的世界。 And they tell us that even if we do it by astrology, they're happy, OK? 他们告诉我们即便我们是用占星术得到的结果，他们也高兴。 We're not actually doing it by astrology. 但是我们并没有利用占星术。 But for the last t...
