Well, you'll know when it crashes, that doesn't help you very much, but you can't always tell whether something's stuck in an infinite loop or whether it's simply taking a long time to compute.
好,你将学到它在什么时候会崩溃,这对你帮助并不大,但是你不能辨别出到底是在一个循环中,有什么东西卡住了呢,还是程序需要很长的时间来计算一个结果呢。
So we know we always want to have our systems in as low an energy as possible, so it makes sense that a bond would happen any time we got a lower energy when we combine two atoms, versus when we keep them separate.
我们知道我们总是希望使我们的系统,处于能量尽可能低的状态,因此就应该有化学键产生,一旦我们合并两个原子之后体系的能量变得更低,相较于分开时。
And I've always wanted to be in the army, but South African army is not as, not that great, you know, so.

Synthesis always occurs in one direction and that makes sense to you now because you know there's a directionality and the chemistry is different going one way than the other and this DNA polymerase only works on the chemistry going in one direction.
NA复制过程是单向的,现在你们该明白原因了,因为DNA单链有方向性,DNA在两个方向上化学性质不同,DNA聚合酶,只在一个方向上起作用
So, in general what we see, and this is always true if we're comparing the same atom, and in general, if we're comparing different types of molecules, but we know that a single bond is always weaker than a double bond, which is weaker than a triple bond.
通常我们会看到,这对比较相同原子来说总是正确的,通常,如果我们要比较不同种类的分子,但我们知道单键,总是要比双键弱,双键总是要比三键弱。
We know that binding energy is always negative, ionization energy is always positive.
我们知道结合能,总是负的,电离能总是正的。
