the winner is the person whose number is closest to 2/3 times the average The winner will win $5 minus the difference in pennies between her choice and that two-thirds of the average."
所选数字最接近2/3倍平均数人是赢家,赢家的奖金是5美元减去,所选数和平均数三分之二之差的百分数
All right, so I did this not at all purposely, but this can point out for you that you need to make sure that the number of electrons that you have in your molecular orbital does match up with the total number that you have in your atomic orbitals.
我并不是故意这么做的,但这告诉我们必须要保证,分子轨道里的电子数,和原子轨道里的,总电子数能对上。
R And we abbreviate that by calling it r, l by two quantum numbers, and an l as a function of little r, radius.

All right. I tried it on 2, I surely didn't expect a precise and exact answer to that but I got something, and if you square this, you'll find the answer kept pretty darn close to 2.
好,我试试求2的平方根,我当然不希望得到一个完全准确的答案了,但是我得到了一个近似值,试试将这个数平方一下,你会发现结果和2相当接近。
Knowing that, I'm going to say, OK, how many pigs are there, well that's just how we're, however many I had total, minus that amount, and then I can see, how many legs does that give, and then I can check, that the number of legs that I would get for that solution, is it even equal to the number of legs I started with, ah! Interesting. A return.
它将给我返回头的总数,知道了这些之后我可以说好了,有多少猪呢,无论有多少组鸡的数目,我只要用总数减去那个值,之后我就可以知道一共有多少条腿,然后再把这个值和题目中的腿数相比较,看它是否等于一开始的腿数,啊!真有趣,有一个返回值。
And again, if I just run this, just to show that it's going to do the right thing, it says enter base, I'm obnoxious, it says oops, wasn't a float, so we'll be nice about it and I enter a height, and it prints out what I expected. I just concatenated those strings together, by the way, at the end.
我再来运行下看是不是做对了,提示输入底,噢,它提示说不是浮点数,我很高兴,然后我输入一个,浮点数作为高度显示结果和我预期的相同,顺便说一句,我只是在最后把这些字符串连接起来了。
