This paper discusses how the Planck formula for black-body radiation can be simplified as Rayleigh-Jeans Law under the condition of low frequency. When the frequency of radiation gets higher, the Planck formula for black-body radiation can be abridged to Wien formula.
本文讨论普朗克黑体辐射公式在低频时可简化为瑞利—金斯公式;在辐射频率较高时,可简化为维恩公式;并且可以推出维恩位移公式。

You can see that many scientists are good at playing music: Einstein played the violin, and German physicist Max Planck was talented in playing the piano.
你可以看到很多科学家都擅长演奏音乐:爱因斯坦会拉小提琴,德国物理学家马克斯·普朗克在弹钢琴方面很有天赋。
"Essentially, I could not agree more with the authors," said Svante Paabo, a biologist and director of the Max Planck Institute for Evolutionary Anthropology in Germany.
“从本质上说,我非常同意作者的观点。”德国马克斯·普朗克进化人类学研究所的生物学家兼主任斯温特·帕波说。

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。
