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。

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。
-
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。

OK, so tiny fraction, tiny fraction of alphas, tiny fraction of incident alphas, tiny fraction of incident alphas deflected through large angles.
这一小部分，极少的阿尔法粒子，极小部分的入射阿尔法粒子，小部分的入射阿尔法粒子,以大角度偏转。
-
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。
-
So that a half circle, instead of calling it 180 degrees, And a quarter circle, instead of 90, It's good to know certain famous angles.
半圆,不说它是180°,四分之一圆,不叫90°,知道一些常用的角度很有必要

To answer the question what is Biomedical Engineering, we're going to spend time on that today and we'll spend time on Thursday, and I want to approach it from a couple of different angles.
我在今天和周四课上,来回答,生物医学工程是什么,我会从一系列不同的角度来带你们入门

Thomas Sowell in the Housing Boom and Bust In just one year, 27% home prices fell by 27% in San Digo, 28% 28% in Los Angles 31% and 31 % in San Francisco.
您在书中说,仅仅一年间，：，“,房价下降了%,在圣地亚哥，在洛杉矶，房价下跌了,在旧金山，下降了。
-
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。
-
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。
-
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。
-
And, moreover, they are at right angles to one another that we've learned.
更多的是，根据我们所学的知识,它们都是和另外一个互成直角。
-
So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.
如果我们考虑碳原子的形状，它是平面三角形，键角是，因为我们有这三个杂化轨道。
-
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。
-
So, deflected through small angles.
所以是小角度的偏转。
-
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。
-
On what else do you use theta for, if not angles?
如果不用angles的话，你会用些什么词去描述角度呢？
-
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。
