最后这个是我们，都很熟悉的普朗克常数。

And finally we have Planck's constant here, which we're all familiar with.

有普朗克常数在第5个。

There is the Planck Constant, number five.

对形成普朗克常数的原因给出一种试探性的解释。

This paper attempts to explain Planck constant. It proposes the definition of charge group.

And the relationship that he put forth is that the momentum is equal to Planck's constant times nu divided by the speed of light, or it's often more useful for us to think about it in terms of wavelength.

爱因斯坦提出的关系式是,动量等于普朗克常数,乘以υ除以光速，或者用波长来表示,通常更容易让我们想明白。

We can make some substitutions here using some of the derivation on the previous board which will give us the Planck constant divided by 2 pi mass of the electron times the Bohr radius.

在这里我们也可以,用我以前在黑板上写过的一些词来取代它,得到的是普朗克常数除以2π电子质量,再乘以波尔半径。
