"Know this: I will not waste time with those who have made the calculation that it's better politics to kill this plan than to approve it."

But the beauty in this calculation is it shows that this concept of electron sharing in an unequal manner is sound and it gets you into the right ballpark.

但在这个计算过程中,真正漂亮的是对电子,非平均共价的考虑很完全,从而指引我们向一个正确的方向思考。

So, if we do this calculation for an electron, saying it moves at 10 to the 5 meters per second, then what we end up with for a wavelength is 7 times 10 to the -9 meters.

如果我们已知电子以，10的5次方每秒的速度运动，那么做一个计算,可以得知它的波长是,7乘以10的负9次方米。

This calculation wasn't done very frequently; that's just if you had one of the satisfactions of knowing how much money you were making.

这个运算并不经常用,除非你非得知道,自己会赚多少钱

But we know that just by this calculation, that we don't have equal sharing.

但是如果通过仅仅计算，我们得不到相同程度的电子共享。

Now as I say, I made this calculation some years ago It doesn't really matter how inaccurate it's going to be As we'll see it's very rough but it makes the point ? How many people are there?

现在就像我说的，我很多年前做了这个计算,到底它有多不精确其实无所谓,我们会看到,这个计算很粗糙,但却给出了一个说明,有多少人？

If I thought there was 2/3 probability they'd choose Left and 1/3 probability they'd choose Right, then I think it's twice as likely they're going to choose Left, and I could redo this calculation.

如果你觉得对手选左的可能性是2/3,而选右的可能性是1/3,即对手选左的可能性是右的2倍时,我们再重新计算一下

It's interesting that this person uses the word calculation; this person has the idea--this was-- 1600 was around the year when probability theory was invented.

He goes back and redoes the calculation, only in this case he says what I am going to do is I am going to redo the calculation for helium, but I am going to consider not just the mass of the electron but the reduced mass of the system.

他回去重新做了计算，仅在这种情况下他才会说说我将要,为氦重做计算，但我认为,不只是电子的质量,还有系统质量的减少量。

And if we do that calculation, what we find out is that the binding energy, in this case where we have no shielding, 72× is negative 8 . 7 2 times 10 to So, let's compare what we've just seen as our two extremes.

我们会发现结合，能在这个情况中，没有屏蔽，等于-8。,所以我们来对比一下,我们在两个极端的案例中看到了什么。

Also, what's the energy per photon of this red laser pointer, and then it's also worth trying a calculation dealing with intensity. So let's also try calculating the numbers of photons that would be emitted by this laser pointer, if, for example, we were to use it for 60 seconds and this were a one milliwatt laser.

同样，红色激光笔的,每个光子能量是多少，这也值得用处理强度的方法计算一下,让我们也计算一下,有多少光子会从这个激光笔射出，举个例子，如果我们使用它持续60秒,这里会有一毫瓦的激光。

So let's do a sample calculation now using this Rydberg formula, and we'll switch back to emission, and the reason that we'll do that is because it would be nice to actually approve what we just saw here and calculate the frequency of one of our lines in the wavelength of one of the lines we saw.

让我们用Rydberg公式,做一个例题，我们回到发射上,这么做是因为这样,可以用我们看到的波长,来验证我们计算的频率。
