Its second function is cosmological. It's explaining cosmic phenomena: the land, the sky, the heavenly bodies and so on, and their origins.

第二个是宇宙学方面的，它解释了宇宙现象：,大地，天空，天体等等及它们的起源。

See you Friday. We'll finish on calorimetry and thermochemistry and then we'll start in on one of the really most difficult topics that we'll deal with all semester, which is a second law and our special function that

好，我们周五见,我们会讲完量热法,和热化学的内容，然后我们会开始,讲这个学期最难的话题之一,第二定律以及我们

Similarly, with the second hydrogen atom, we've got the nucleus in the middle, and the 1 s b wave function around it.

类似的，在第二个氢原子里面，我们在中间有原子核，周围有1sb波函数。

And the reason that we now on the second line have the equal sign is because this function GetString has what's called a return value.

我们之所以,在第二行代码GetString前面加上等号,是因为这个函数会带回一个,返回值。

Think of this as a function that takes two techs arguments, the first of which is univs and the second of which is techs. And this is just a different syntax for writing that function call.

想下有两个参数的函数,第一个是univs第二个是,这就是对于函数调用的,不同语法的书写规则。

Mathematically complete problem is that you can find the function x of t by saying that the second derivative of the function is equal to -k over m times the function.

这个数学问题就是,你可以求出函数 x,只要令函数的二阶导数,等于 -k 除以 m 再乘以函数

And when we describe this in terms of talking about chemistry terminology, we would call the first one the 1 s, and 1 is in parentheses because we're talking about the first electron there, and we would multiply it by the wave function for the second one, which is also 1 s, but now we are talking about that second electron.

当我们用化学术语来,描述它的时候，我们称第一个为“1s“,括号中的1是因为我们,在谈论第一个电子,而且我们会用它的波函数，乘以第二个,第二个也是“1s“,但是我们现在谈论的是,第二个电子。

In other words, your job is to guess a function whose second derivative is a, and this is called integration, which is the opposite of differentiation, and integration is just guessing.

换言之,你的任务是要猜出一个二阶导数为a的函数,这就是积分,和微分恰恰相反,积分就是猜
