The other thing you want to do is find the part of the program that is most likely at fault.
你们要做的另外一件事就是找出,最可能出错的那一部分代码。
The reason is because the predominant force at this point is going to be the attraction that's being felt between the nuclei and the electrons in each of the atoms.
这是因为这时候最主要的力,是吸引力,它来自于,其中一个原子的电子与另外一个原子的原子核之间。
Moving a stack of size 3, again, if I want to go over there, I need to make sure I can put the spare one over here before I move the bottom one, I can't cover up any of the smaller ones with the larger one, but I can get it there.
移动上面的三个圆盘的话,我在移动最底下的圆盘之前,同样要确保剩下的,是在另外一个柱子上,因为我不能把大的圆盘,放在小的上面。
And the most religiously volatile part of the world tends to be the youngest.
另外,世界上在宗教方面最不稳定的部分,常常是青年人。
And, one other thing that I failed to point out, if you take a look at the energies associated with the outermost electrons, in this case, lithium, you see it's 0.5 megajoules per mole, and then what's the 6.26?
还有另外一点我忘记提到的是,如果你观察离最外层,的电子的能量,在这种情况,对于锂,你可以得到,它是每摩尔0。5兆焦,那么6。26是什么呢?
These would have been inscriptions either on pottery, which the earliest ones are,or on stone, but otherwise I'm sure there was writing on perishable material-wooden plaques, probably not yet paper, but these would have been destroyed.
有些是刻在陶器上的铭文,最早期的时候,是刻在石头上的,但另外,我能肯定,有些是写在易腐蚀的材质,比如木头,或者瓷片上的,当时应该还没有出现纸,但是这些都被毁坏了
So, I want to contrast that with another concept that seemed to be opposing ideas, and that is thinking about not how far away the most probable radius is, but thinking about how close an electron can get to the nucleus if it's actually in that orbital.
我要将它和另外一个,看起来相反的概念相比较,我们不是考虑,最可能半径离原子核有多远,而是考虑如果电子在那个轨道上,能多接近原子核。
We have one node here, and we can again define that most probable radius.
在这里有个一节点,另外我们可以定义最可能半径。
This is the strongest memory I have, and I remembered a) that I didn't learn them, and that was really bad because it kept coming up, but the other thing I remember is that I had no idea why they were important. I didn't really understand what any of these molecules were.
这就是我最深刻的记忆,我记得我并没有学好,这十分不好,因为之后它们总是不断出现,但另外的事情我记得,是我完全没有概念为什么。
The other thing that I want you to notice, is if you look at the most probable radius, for the 2 s orbital it's actually out further away from the nucleus than it is for the 2 p orbital.
另外一个你们要注意的地方就是,如果你们看它的最可能半径,2s轨道比2p轨道的,要更加远离原子核。
