So with his optic glass, his telescope, Galileo was able to discern spots on the orb of the moon.
因此通过他的磁光玻璃,望远镜,伽利略能够分辨出月亮轨道上的斑点。
No one, until this time, had suggested that a system would be subjected to quantization except for light.
在他之前,还没有人提出过,除光系统外的量子化系统。
We've got wind, we've got a primeval chaotic, Watery mass or deep, and then surprise, There's just a word,"Let there be light."
我们有了气流,有了原始的混乱,狂放的水流,混沌,但奇怪的是,只有一句话,“要有光“
Just remembering that violet is the end that actually has the shortest wavelength, which means that it also has, of course the highest frequency.
就知道了,所以这应该,不是问题,记住紫色光,最后一个,它的波长最短,也就意味着它的频率最高。
Oedipa Maas in Crying of Lot 49 will sit up on a bluff overlooking San Narciso, and she'll look down at the pattern of light.
拍卖第四十九批》里的奥狄芭·马斯也会坐在悬崖上,俯看纳西索,看各式的光。
That's because it's here where the rigid polarities between light and dark and good and evil, all of these absolute oppositions, begin to collapse.
这是因为这里就是光与暗,善与恶之间严格的两极分化,及所有绝对的对比开始崩塌的地方。
A gig is 10 to the 9, so it does two operations in the length of time it takes light to get from one foot off the table down to the table. That's amazing.
因此光行进一英尺的,时间内电脑可以,进行两次基本运算,这太神奇了。
The moon says to him:] 'Oh, I've been scanning pond and hole And waterway hereabout For the body of one with a sunken soul Who has put his life-light out.
月亮对他说],哦,我一直在审视着池塘和地洞,还有在附近的排水沟,因为一个人的灵魂已沦陷,熄灭了他的生命之光。
The problem is, if your brokerage firm fails you could lose a lot; you could lose your cash account and your security account.
可问题是,一旦经纪公司破产,你可能损失惨重,赔光你现金账户和证券账户上所有的资金
In fact the number of photons headed to your your eyes from those 2 tiles is exactly the same, physically that is the same.
实际上这两张瓷片,投射进你眼睛的光量子是一样的,从物理学的角度上说是完全相同的。
He might be a scientist and know all sorts of things about how light works.
他可能是个科学家,通晓光的原理
Computers don't have so much the same kind of blinking lights.
计算机没有这么多种类的闪烁光信号。
He did it to bring more light, he did it to bring more air, he did it to free the flow for capital, money; that's why the department stores are on the boulevards.
他这么做是为了多点光,多点新鲜空气,他为了使资产的流动更为自由,这就是为什么百货商店都建在大道旁边
Like in popular music there's often a couple of verses and a chorus and a bridge and you can predict each different movement of the piece, and that's more regular than-- Couldn't say it better myself.
就像在流行音乐中有很多的曲段,副歌,和过渡乐节,这样你就可以预测到音乐的每一个变化,这样就比别的要规则-,光我一个人不好说太细。
Physicians over the years of having this instrument have learned how to be very sophisticated about looking at these pictures and diagnosing when something is wrong inside the chest, for example.
这些年来,使用这类设备的医生,已经熟练地掌握了,通过看这些X光片,来诊断,胸部疾病的方法
It is a glass tube. He wants to narrow the light so he puts a couple of slits here.
这是根玻璃管子,他想要减少光的发散,所以在这里开了几个口子。
So, let's look, Act II Scene II. You remember this, Romeo: "but soft, what light through yonder window breaks. It is the east, and Juliet is the sun."
让我们一起看,第二幕第二场,你们记得吧,罗密欧说,但是,温和的,那边窗子里,亮起来的是什么光,那就是东方,朱丽叶就是太阳“
So, what we would expect is that there is a relationship between intensity in kinetic energy because it was understood that however intense the light was, if you had a more intense light, it was a higher energy light beam.
光强和能量之间,应该有一定的关系,因为在我们的理解中,不管光强是多少,光的强度越大,光束能量越高。
Lolita, light of my life, fire of my loins. My sin, my soul.
我生命之光,我欲念之火,我的罪恶,我的灵魂。
One question that comes up is that maybe-- this is for the U.S. data-- and some people say, well, maybe, why are we looking at the U.S.?
这又产生了一个新问题,这是采用美国市场的数据得出的结果,有些人会问,为什么光研究美国市场呢
And I hope, as you are reading, you notice that chapter opening where once again Dean appears at the door when Sal shows up, and he's totally naked.I hope you noticed that. It's the third time that we see that so there is an eroticism between them.
我也希望,你们在阅读时注意到那一章,就是曾经萨尔去找迪安时,迪安又一次是光着身子,开的门,我希望你们注意到这一点,这是第三次,我们看到这一幕,所以他们对彼此有着性欲。
The next thing that they wanted to look at was the actual intensity of the light and see what the relationship of intensity to kinetic energy is.
下一而他们要研究的是光的强度,看一下光强和能量之间的,关系是怎样的,我们预期。
So, we'll take a little bit of a step back after we introduce quantum mechanics, and talk about light as a wave, and the characteristic of waves, and then light as a particle. And one example of this is in the photoelectric effect.
等我们介绍完量子力学后,我们要回过头来讨论下光,作为一种波和它的波动性特征,以及光作为一种粒子,其中的一个粒子就是光电效应。
That makes sense because we're losing energy, we're going to a level lower level, so we can give off that extra in the form of light. And we can actually write the equation for what we would expect the energy for the light to be.
这很合理,因为我们在损失能量,我们要到一个更低的能级去,我们要以光的形式给出额外的能量,我们可以写下光能量的方程。
So it turns out that we can, in fact, use the energy levels to predict, and we could if we wanted to do them for all of the different wavelengths of light that we observed, and also all the different wavelengths of light that can be detected, even if we can't observe them.
事实上我们可以用能级预测,而且如果我们想的话,我们可以,对所有观测到的光的波长预测,也可以对所有探测到的光预测,即使我们看不到它们。
If I consume it all this year, I will be starving.
如果我把今年的收入都花光了就会挨饿
So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.
重要的信息,如果我们看看,这些不同种类的光,微波,如果被分子吸收,它的频率和能量可以,使分子转动,这当然的,会产生热量,这就是你们微波炉的工作原理。
So, one thing they did, because it was so easy to measure kinetic energy of electrons, is plot the frequency of the light against the kinetic energy of the electron that's coming off here. And in your notes and on these slides here, just for your reference, I'm just pointing out what's going to be predicted from classical physics.
他们做的其中一件事,因为测量电子动能是很容易的,就是画出光的频率,和出射电子动能之间的关系,在讲义的这里,仅仅是,为了做个比较,我要指出,经典物理所给出的预测,这个不作为对你们的要求。
So that should mean that the energy that's transferred to the electron should be greater, but that's not what you saw at all, and what you saw is that if you kept the frequency constant there was absolutely no change in the kinetic energy of the electrons, no matter how high up you had the intensity of the light go.
所以这意味着转移到电子,上的能量也越大,但这并不是,我们观测到的现象,我们所看到的是,如果固定光的频率不变,不管光强如何变化,电子的动能没有任何变化。
And as you read Lolita, try to notice how much light imagery there is.
你们读Lolita的时候,要注意用的关于光的比喻。
