And this is Erwin Schrodinger, and this is the equation that he put forth where we have hat psi being equal to e psi.
这就是埃尔文？薛定谔，在这个方程中,他提出,所以，让我们来解释一下。
-
This is E equals zero. N equals infinity.
这是第N个能级，能量为。

London, already by the late sixteenth century, one-sixth of all the people, I think this is E.A. Wrigley who pointed this out a long time ago--one-sixth of all the people in England went to London frequently, because London was absolutely gigantic as a city.
伦敦,早在十六世纪后期,六分之一的人口,我想是E.A莱格力很久以前给出的这个数据,他指出,当时有六分之一的英国人,会经常去伦敦,因为伦敦当时是个巨型城市
-
And we can simplify this expression as saying negative e squared over 4 pi, epsilon nought r squared. Epsilon nought is a constant, it's something you might see in physics as well.
也会遇到它,在这里，你可以就把它,理解为一个转换系数,我们需要做的。
-
So I'm thinking e'oh, is this good plumbing for the video Internet?
所以我在想，额哦，这是对网路视频好的渠道么？
-
All right, so there we are, but is this, from D to E, a half step?
好了,明白了,但这里,从D到E,是个半音级吗
-
Now, just to repeat, again I know I've got some math phobics in the audience, let me just slow down a second, all I'm doing here is I'm saying look at this equation of the pink line, look at this equation of the blue line, X is when they cross, i.e., they are equal to each other.
我再重复一遍,我知道你们之中有些人数学不怎么好,我放慢一点说,我是这么解的,看这条粉线的方程,还有这条蓝线的方程,X是二者的交点,也就是说这点两个方程相等
-
I know some of you come from Europe and other parts of the world where the ground floor is rez-de-chauss?e or some silly thing like this 1 and you push a button on the elevator to one and you go up to the first floor.
我知道你们中间有些人来自欧洲,或者世界其他地方，你们那里的一楼,和地面齐平，或者像这样可笑的事情,比如你要按下电梯的按钮,然后才能上到真正的1楼。

In other words, if the rise in instability is greater than the fall in stability, delta E this is a positive delta E.
换而言之，如果不稳定性的增加,大于稳定性的降低，将会有一个正的。
-
08 This is 4.19. You get the E of the HF is equal to 608.
这是4。19，HF的E是。
-
This e term here is the energy, or in our case when we talk about an electron in a hydrogen atom, for example, the binding energy of that electron to the nucleus.
这里的“E“是指能量，或者在我们谈论一个,氢原子的电子时，举例来说，是电子对于原子核的结合能。
-
This is the e beam.
这是电子束。
-
So we have the operationon the wave function in terms of r, theta, and phi and remember this e is just our binding energy for the electron, and we get back out this wave function.
我们用r，θ，φ来表示,将算符作用于波函数,而且记住e仅仅是电子结合能，然后后面加上波函数。
-
What we've written is a whole step, so we've got to indicate that this is just a half step away in that fashion, D to E-flat.
而这里写的是一个全音级,所以我们要在这里标出,从D到降E只有半音级
-
This is Z times e in the center.
原子中心的电荷为e的Z倍。
-
e This is just base e, natural logarithm.
减去EXP自然对数中的。
-
And what we say when we talk about the delta energy is I E 2 that this is going to be equal to i e 2, or the second ionization energy, or we could say the negative of the binding energy of a 2 s electron in b plus.
那么我们说,Δ，E，应该等于，或者说第二电离能，也就是正一价硼中，2，s，电子的,束缚能的负值。
-
That's what this is called by Jan Steen, S-T-E-E-N.
简·施特恩就是这么说的 简S-T-E-E-N
-
And what he could show was that it could be expressed, this is a picture from his 1994 science paper, in that e coli, and it is going to fluoresce green.
他证明了它可以被表达，这是1994年science文章里的一张图，在这大肠杆菌里，它有绿色的萤光。
-
So, this is the E attractive.
所以这就是E引力。
-
This is Pieter Claesz, C-L-A-E-S-Z, probably mispronounced.
这是彼得·格莱兹的作品,C-L-A-E-S-Z,我可能发音不准确

eastern daylight time to my office to my e-mail address So, this is an example: lazy college professors never produced officially educated graduates to dramatically help executives trim yearly losses.
用电子邮件发给我或者发到我办公室也可以,这是一个例子：,一些懒的教授从来没有,正式的培养研究生,帮助主管们减少亏损。
-
I know the energy in this first pair would equal -e^2 That is just going to equal minus e squared over 4 pi epsilon zero r naught.
我们明白第一对的能量将会等于,等于,/4πε0，R圈。
