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
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 thin
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

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 th
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 begi
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
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
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

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
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 matt
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
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
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 frequenc
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
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
