But not many black musicians were known for writing or performing classical music.

Also, when we're looking at the Schrodinger equation, it allows us to explain a stable hydrogen atom, which is something that classical mechanics did not allow us to do.
当我们看一个薛定谔方程的时候，它给出一个稳定的氢原子,这是在经典力学中做不到的。
-
Classical, maybe a little more than that, but not all that many. Here's-- I don't know, we should do a survey sometime.
古典音乐,也许稍多一点,但没有多少,大概,我不清楚,也许应该找时间做个调查
-
And when we say bigger, remember this is not a classical description we're talking about.
当我们这里说大，记住我们说的不是经典的描述。
-
For us, we can start not so all the way back at Classical Greece, but with Alexander the Great, and the beginning of Hellenization; that is, the Grecization of the eastern part of the Ancient Mediterranean.
我们不必追溯到古典希腊时期，而从亚历山大大帝及希腊化初始讲起;,就是古代地中海东部地区的希腊化。
-
And as if this were not enough, near the very end of his life, he returned to his classical studies translating all of Homer's Iliad and Odyssey.
这好像还不够，在他晚年的时候，他又回到了对经典的研究,翻译了荷马的《伊利亚特》和《奥德赛》
-
It is also interesting to notice who does not colonize at this early period and the answer is all the most famous cities of Greece in the Classical Period.
另一个有意思的问题是,谁在早期并不殖民,答案是,古希腊时期的所有名城
-
I think engineers have a role to play in that, but it's not sort of classical Biomedical Engineering in the way that developing an artificial heart is where you can see that.
我认为工程师们,在其中扮演了重要角色,但它又不像传统生物医学工程那样,去研究人造心脏之类,实实在在的东西
-
This almost certainly is not the right story but again, just as in phobias, some ideas of classical conditioning may play some role in determining what we like and what we don't like sexually.
这个解释肯定是错的,但是，与在恐惧症中的作用相同，经典条件作用,或许对我们在性活动方面的喜恶,起着一定的决定作用。
-
So, what he did was kind of impose a quantum mechanical model, not a full one, just the idea that those energy levels were quantized on to the classical picture of an atom that has a discreet orbit.
还不是完整的,只是这些能级，是量子化的概念，作用到原子有分立轨道的经典原子模型上,当他做了一些计算后,他得到有个半径,他算出来。
-
And when we talk about size, I'm again just going to say the stipulation we're not talking about an absolute classical concept here, but in general we're going to picture it being much further away from the nucleus as we move up in terms of n.
当我们说到尺寸时，我们只是说――,经典的绝对的概念，而是它大约,离原子核有多远。
-
But once we got to the atomic size scale, what happens is we need to be taking into account the fact that matter has these wave-like properties, and we'll learn more about that later, but essentially classical mechanics does not take that into account at all.
但一到到了原子尺度量级，我们必须考虑到物质,这时候有波动性质,关于这点我们今后将会学到更多,但本质上经典力学并,没有考虑这个性质。
-
And the reason that quantum mechanics is going to work where classical mechanics fails is that classical mechanics did not take into account the fact that matter has both wave-like and particle-like properties, and light has both wave-like and particle-like properties.
上发生的行为,量子力学得以成功,而经典力学却失败的原因,是因为经典力学,不能包容物质的，波动性和粒子性,和光的波动性和粒子性。
-
The classical hoplite formation then was not the long lived military institution of scholarly tradition, but merely one phase in a history of almost four centuries of slow change towards ever denser and more cohesive heavy infantry formations."
这种方阵的形成,并不是经过长期传承的传统军事制度,只是步兵阵型演变的一个阶段,战阵逐渐向更加紧密坚固的步兵阵型转化,而这个变化持续了约有四个世纪"
-
And we talked about this before--that classical music, probably eighty-five percent of it, does not involve a text, and that's a whole different ballgame because then you have to communicate meaning in a completely different sort of way.
我们之前也说过，古典音乐，大约百分之八十五，都没有歌词，所以这就让这两者产生了本质的区别,听众必须用完全不同的方法理解音乐的内涵。
-
So, for example, when people, and we'll talk about this next class, were looking at different characteristics spectra of different atoms, what they were seeing is that it appeared to be these very discreet lines that were allowed or not allowed for the different atoms to emit, but they had no way to explain this using classical physics.
举个例子，当大家看到,不同原子的特征光谱时,他们看到的是一些分离的线,那可以使不同的原子,发射或不发射出去，但是这些无法用经典物理来解释。
-
We all know that there is this thing in music called "Beat" and to the extent that popular music is more interesting and that you-- everybody likes it and will go dance to it is because it's really foregrounding beat and rhythm in an important way that classical music does not.
我们都知道在音乐中有种概念称作,拍,这也就是为什么流行音乐,从某种意义上说会那么好听,大家都会喜欢,并且愿意随之起舞,就是因为它把拍和节奏,摆在显要位置,而古典音乐就不是这样
-
I want to make you a richer person, a broader person, by instilling you with an unending deep and abiding understanding of classical music, so that's part of this, and not just here for Yale but for your life after Yale.
我希望你们成为更有内涵的人,心胸更加宽广的人,通过循循善诱,让你们体会到古典音乐的博大精深,这是一点,并不只在耶鲁大学,还有你以后的人生道路
-
So if you get the CD set, not only do you get a wonderful beginning library of classical music but in effect you get a lifetime service contract with it.
所以一旦你买了整套CD,你不仅可以拥有一个古典乐图书馆,而且还可以享受终身服务
-
So think about what that means, we're, of course, not talking about this in classical terms, so what it means if we have an electron in the 2 p orbital, it's more likely, the probability is that will be closer to the nucleus than it would be if it were in the 2 s orbital.
想想这意味着什么，我们不是从经典的角度考虑，这意味着如果我们有个电子在2p轨道上，它更有可能比在2s轨道上,更加靠近原子核。
