What's the point of this? Again, now that I can think about things recursively, I can similarly break things down into simpler versions of the same problem. It could be one version.

这些的意思是什么呢？再一次我想说,我既然能够以递归的方式思考了,那么我就可以简单地把问题,转化为更简单的同类问题。

As long as it's reversible, you know what the efficiency has to be, and in principle, you could break it down into a bunch of steps that you could formulate as isothermal and adiabatic.

只要这个循环过程是可逆的，你们知道效率是多少，从理论上说，可以将总过程,分解成一系列绝热,和等温的小过程。

The word "carbohydrate," as you might imagine, if you ever thought to break it down means the combination of carbon and water.

碳水化合物这个词,如你所想,如果你把它进行拆分的话,就是碳和水的结合物

Formaldehyde cross-links proteins, so, if you treated this virus with Formaldehyde, even it was able to enter a cell, it couldn't break down anymore.

甲醛使蛋白质发生交联反应,因此,如果你对病毒使用了甲醛,即使它可以侵入细胞,它也不能够再进行分解

What does that mean? Well, it means that, you know, there's maybe, let's say, that in the next 24 hours it will break down.

这意味着什么 好的,这意味着,就是说,有可能,这个原子会在未来的二十四小时内分裂

Well, break it down into pieces. Suppose x is positive. Does it terminate? Sure. All right?

好，分开来讨论，假设x是整数,程序会终结么？肯定会的对不对？

Now, according to quantum mechanics under the standard interpretation, that's all there is to say about it. You have an atom like that, 80 percent chance in the next 24 hours it will break down.

按照量子力学的正统理论,也就是说,在未来二十四小时内,这个原子有百分之八十的概率会分裂
