Torrey says it was no small feat composing shots of the ruins without any tourists in the frame, but even more difficult was chasing the ever-changing angles of natural light.

If these bonds were all completely of equal distance apart, whether is was a lone pair or bonding electrons, 5° the angles would be 109 . 5 degrees.
如果不管它是孤对，还是成键，它们等距分开的话，键角是109。
-
You know when you add 2 polar forms, you add the radii together, you don't add the angles together, you need to do it in Cartesian form.
表示形式的不同理解，返回给你了不同的值，这也就带来了一系列的问题，第二个问题是。
-
We have two lone pairs, so if we thought about what the bonds were everywhere, 5° it would be 109 . 5, but it's bent because we're only looking at the bonds, we're not counting the Lewis structures in naming our geometry, but they do affect the angles.
我们有两个孤对，所以如果我们考虑它会成怎样的键时，应该成109。,但它是折线型，因为我们只考虑成键，在几何形状里不考虑Lewis结构，但它会影响角度。

That's brilliant he made all of these incredible shots, and angles, and the dissolves in the structure of it.
他能够做出这些难以置信的,镜头，角度和解构,这是很高明的。
-
I'm going to give you the data set of the scattering angles of the atoms.
我会把,这些原子散射角的数据发给你。
-
No matter where you specify your electron is in terms of those two angles, it doesn't matter the angular part of your wave function is going to be the same.
不论你将，这两个角度,取成什么值，波函数的角向部分,都是，相同的。
-
How far you are away from the nucleus in terms of a radius, they don't depend at all on those two angles, theta they're independent of theta phi and they're independent of phi.
只和离核子的距离，也就是半径有关，它们和,另外两个角度无关，它们不决定于,也不决定于。
-
A tiny fraction of the incident alpha particles were deflected through large angles.
极小部分的入射的阿尔法粒子,发生大角度的偏转。
-
Majority of alphas transmitted, that means, when I use the term transmitted that means passing through in the direction that they were originally traveling, transmitted and some deflected through small angles.
阿尔法粒子大部分穿过去了，当我用穿透这个词,是说按照原来的方向,穿透过去,包括有些小角度的偏离的穿透。
-
We call that a node, r and a node, more specifically, is any value of either r, the radius, or the two angles for 0 which the wave function, and that also means the wave function 0 squared or the probability density, is going to be equal to zero.
节点就是指对，于任何半径，或者，两个角度,波函数等于，这也意味着波函数的平方或者概率密度,等于，我们可以看到在1s轨道里。
-
So if, in fact, we want to describe a wave function, we know that we need to describe it in terms of all three quantum numbers, and also as a function of our three positional factors, which are r, the radius, phi plus the two angles, theta and phi.
实际上，我们想描述波函数，我们知道我们需要,用这三个量子数来描述它，同样，波函数还是,三个位置变量的函数，它们是r半径，还有两个角度theta和。
