So there was a good question in Wednesday's class about the de Broglie wavelength and if it can actually go to infinity.
在周三的课上有个关于德布罗意波波长的问题,非常好，就是它能不能到无穷大。

Vallombrosa literally means "shady valley," and I think it recalls Galileo's shady place, Valdarno, another valley.
瓦隆布罗萨字面上的意思是“成荫的村庄“,我认为这使人想起了伽利略阴暗的处所，另一个村子，瓦尔达诺。
-
If de Broglie is correct, we could then model the electron in its orbit not moving as a particle, but let's model it as a wave.
如果德布罗意是对的，那么我们可以在电子轨道中建立电子模型,不是像粒子一样运动，而是像波一样运动。

We even have a Hummus restaurant now in Ambrose.

My name is Dr. Paul Bloom.

-
So that would probably be de Broglie's answer for why, in fact, we're not observing the wavelength behavior of material on a day-to-day life.
所以那就可能是德布罗意关于,为什么我们无法再日常生活中,观测到物质的波动行为的答案。
-
So I mentioned, however, that in terms of de Broglie's work. T his was Nobel Prize worthy, absolutely, but it was also his PhD thesis.
然而，我提到的是德布罗意的工作，这个工作是绝对是,配得上诺贝尔奖的，而且它也是德布罗意的博士论文。
-
De Broglie has said electrons, under certain circumstances, can be modeled as behaving as though they are waves.
德·布罗意说过电子，在某种特殊的情况下，也可以运转，即使它们都只是波。
-
And what de Broglie said is well, if it's true that light, which has a wavelength can have momentum, then it must also be true that matter, which has momentum, also has a wavelength.
德布罗意说的是，如果光具有波长和动量是对的,那么物质具有动量和波长,也一定是对的。

-
This is fast. Look, de Broglie was 1924.
有点快，德布罗意在1924发表了自己的论文。

Einstein is only a theoretician and de Broglie is a theoretician, so one theoretician propping up another theoretician, this is a mutual admiration society.
爱因斯坦是个理论家,布罗意也是，因此一个理论家可以去认可另一位，这是个彼此仰慕的社会。
-
But let's just try maybe one of the basic questions they could ask, and they can say, all right, de Broglie, so you say that all matter, absolutely all matter has wave-like behavior.
让我们试一试他们,可能问到的一个基础问题，他们会说，好的，德布罗意，你说所有的物质，所有物质绝对会有波的特性。
-
This is the initial part of the simile that describes the leaves: "thick as Autumnal Leaves that strow the Brooks / in Vallombrosa, where th' Etrurian shades / high overarch't imbow'r."
这是描写落叶的比喻的开始部分：,“他们人数众多，稠密得像秋天的繁叶,/在瓦隆布罗萨，厄特鲁利亚的光辉逐渐暗淡“
-
So this validates de Broglie and it also validates the whole concept of wave-particle duality.
这就证实了德布罗意的观点,也证实了,波粒二象性的原理。
-
And so if you say de Broglie's name to many physicists, the tagline they associate with de Broglie is "matter waves" as distinct from light waves.
如果你向很多物理学家提及到德布罗意，他们觉得德布罗意中心思想就是,是物质波不同于光波。
-
What de Broglie is saying we can know the wavelength of any matter at all, as long as we know its mass and it's velocity.
通过德布罗意所说的,只要我们知道了,它的质量和速度，我们可以知道,任何物质的波长。
-
We are going to start with de Broglie.
从德布罗意开始。
-
It refers solely to trees, and Vallombrosa is the place "where th' Etrurian shades / high overarch't imbow'r."
这个比喻指的就是树木，地点是瓦隆布罗萨,“在瓦隆布罗萨，厄特鲁利亚的光辉逐渐暗淡“
-
But de Broglie has told us that the wavelength is related to the instant velocity through this formula.
但德布罗意曾说过,波长是和瞬时速度相联系的,通过这个公式。
-
One is that he's just re-arranged an equation here and gotten both his PhD thesis and a Nobel Prize, but I think the more representative way to think about this is the real revolutionary idea that he put forth, which is that matter can actually behave as a wave.
一个是德布罗意仅仅,重新排列了一个方程,而且完成了博士论文并获得诺贝尔奖，但是我认为更具有代表性的观点,是他提出了实在的革命性的观点，那就是物质会有波的性质。
-
What he did was took de Broglie motion of the electron as a wave and developed a wave equation for such matter waves.
他所做的就是,用电子的德布罗意运动,作为波并且对于那种物质波,给出波动方程。
