(Speaking) Mikhail Khodorkovsky, the imprisoned Kremlin critic and former head of the Yukos Oil Company, in a recent op-ed column, said Russia's demand for skills in fundamental and applied sciences is declining in light of the appetite for raw materials and corruption.

You'll see light coming out, but it's, of course, going to be bulk light -- you're not going to be able to tell the individual wavelengths.

你会看到有光出来，但当然这些光是混在一起的,你不能看到每个单色光。

I think it's understandable that Milton would call the power of light "offspring of Heav'n first-born."

我认为弥尔顿,称光明的力量,是上帝最初的产物“

He's also decided to give up leadership in Light up the World Foundation to start a company in India that will develop a more energy-efficient and cheaper lighting system that he hopes will bring even more light to the world's poor.

What does it feel like to be the machine while it's looking at-- while it's got its little light sensors pointed at--the red ball?

当机器以电子眼,对着那个红色的球,它会有什么样的感觉

There's also a part of the payoffs that's analogous to forcing me to drink Bud Light or forcing the forcing the Pepsi drinkers to drink Coca-Cola.

还有一部分类似于,强迫我喝百威淡啤酒或者,强迫喜欢喝百事的人去喝可口可乐

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, for example, here we're showing rubidium and potassium and sodium plotted where we're plotting the frequency -- that's the frequency of that light that's coming into the metal versus the kinetic energy of the electron that's ejected from the surface of the metal.

让大家看来都是可以理解的事情,就是把不同金属的观测结果,画到一张图里面来，例如这里,我们展示的是钠，钾,铷的频率-这是照射金属的光的频率,和金属表面出射电子动能的关系。

It's now exactly that power from which Milton has been excluded by virtue of his blindness -- light: "Hail holy Light, offspring of Heav'n first-born, / Or of th' Eternal Coeternal beam May I express thee unblam'd?"

而是弥尔顿已经被失明剥夺的一种力量,圣光，你是上帝最初的产物，永恒的光束,我是否可以向你表达我无限的敬意“

I move out of the room toward the bathroom, planning to brush my teeth. As I enter the bathroom, it's much more light, I look in the mirror and-- here's where things get really weird--I don't see anything.

我离开卧室走向浴室,要去刷牙,当我走进浴室时,光线明亮了些,我看着镜子,从这里情节就诡异了,我什么也没看到

So you know that x-rays are higher frequency than UV light, for example, that means it's also higher energy than UV light, and if you think back to our photoelectric effect experiments, do you remember what type of light we were usually using for those? Does anyone remember?

你们知道，X，射线的频率比紫外光高，这意味着，它的能量也比紫外光要高，那么，请大家回想一下我们的光电效应实验，大家还记得当时我们用的是什么光源吗？,有人记得吗？
