When we did the spring, we had this theory of Hooke's Law that told us something, and we built a simulation, or built some tools around that theory.
当我们写弹簧程序的时候,我们有胡克定律来告诉我们原理，然后我们建立了一个仿真模型，或者说是在这个理论基础上建立了一些工具。

It's a critique of the idea of anything that has a center, one which is at the same time an enabling causal principle.
它是在评论任何事物都有一个中心的想法，与此同时存在一个任意的原理。

So, if you look in chapter one, you will find these definitions for different atomic groupings starting down here with the elements and moving through up through complex matter.
如果你们读第一章，你们会发现不同的原子组的定义,从底下开始有一些基本原理,往上还有复杂的物质。

Problems like the artificial heart are still unsolved, there's still room for innovation, still room to learn from what hasn't worked before, to learn from science, and to design something better.
人工心脏技术中存在的问题还没有解决,还有创新发展的空间,仍有从未涉足的领域来研究,通过对科学原理的学以致用,去设计出更好的产品

Pauli So, here, Pauli came out on top, we say, and he's known for the Pauli exclusion principle, which tells us that no two electrons in the same atom can have the same four quantum numbers.
在这里是，他因为Pauli不相容原理而出名，这个原理是说同一个原子中的两个电子,不能有相同的第四量子数。

Pauli How about Pauli, like the Pauli exclusion principle?
有多少人听说过，就是Pauli不相容原理的Pauli？

So we have two electrons in our bonding orbital, but because we use the same rules to fill up molecular orbitals as we do atomic orbitals, so the Pauli exclusion principle tells us we can't have more than two electrons per orbital, so we have to go up to our anti-bonding orbital here.
所以在成键轨道上有两个电子，但因为我们用了和原子轨道时,用的相同的规则，所以Pauli不相容原理告诉我们,一个轨道上不能有两个以上的电子，所以我们需要填充到反键轨道上去。

That's why molecular biology, one of the reasons why it's turned out to be such a powerful tool, because if you can think creatively you can find all different ways to using these very simple principles to recombine molecules, to make unique new DNA sequences.
这就是分子生物学,如此有用的原因之一,因为如果你有创造力,你可以用各种方法,运用这些简单的原理来重组分子,创造独特的DNA新序列
