These proton rivers are a natural energy source that many  scientists believe billions of years ago, powered the first transition from  regular chemistry to living biochemistry.

这些质子流是一种天然能源， 许多科家认为， 数十，正是这种能源驱动了从普反应向生命生物的首次转变。

And I think you have heard about it probably when you took chemistry with Ms. Pittard, because you should have learned this in first semester, maybe second semester, general chemistry.

我想你可能在跟Pittard女士的时候听说过这个，因为这应该是你们在第一期，也许是第二期的普课上习的内容。

The combination of fusion and fission makes a really powerful bomb Nuclear weapons are so destructive because messing with subatomic particles can unleash a lot more energy then just breaking chemical bonds like typical explosives do.

聚变和裂变的结合造就了一颗威力巨大的炸弹。核武器之所以具有极大的破坏力，是因为操纵亚原子粒子可以释放出比普炸药仅仅断裂键更多的能量。

So, and this is something we talk about in gen chem a lot is you'll learn these basics of chemistry, but there's a lot of gray areas or things that we maybe don't know, or you can't say a hundred percent.

所以， 这是我们一般在普课上会讨论的内容， 你会到一些基础知识，但有很多灰色地带或者是我们可能不知道的事情，或者你不能说百分之百确定的事情。
