我从et++中学到，一个成熟的框架总是明显地包含了很多重复出现的设计模式，可以让你得到更多的东西，像扩展性，解耦性，和最终的优雅性。

As I reflected on ET + +, it became apparent that a mature framework contains recurring design structures that give you properties like extensibility, decoupling, and last but not least, elegance.

《病女孩》这本书不仅唤起我对Donna的回忆，也让我开始瞭解她身边的人﹝包括我自己在内﹞很可能影响了她做出停药这个重大的决定。

“Sick Girl” brought back memories of Donna. But it also allowed me to begin to understand how those around her, myself included, might have contributed to her fateful decision.

I have yet to show you the solution to a wave function for the hydrogen atom, so let me do that here, and then we'll build back up to probability densities, and it turns out that if we're talking about any wave function, we can actually break it up into two components, which are called the radial wave function and angular wave function.

我还没有给你们看过,氢原子波函数的解，让我现在给你们看一下，然后再来说,概率密度，实际上,对于任何一个波函数来说，我们可以把它,分解为两部分，分别叫做径向波函数,和角向波函数。
