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。

His relationship with Paul Roberson here at Princeton, Einstein would embrace him, not that he would agree with everything, was so tied to working people's and poor people's.

他就和普林斯顿的Paul，Roberson的关系很好，爱因斯坦会拥抱他，不是因为他认同每一件事，是紧紧与工人阶级和穷苦人民的心联系在一起的。
