物理的笑话,请解读
One day in class, Richard Feynman was talking about angular momentum. He descr
ibed rotation matrices and mentioned that they did not commute. He said that S
ir William Hamilton discovered noncommutivity one night when he was taking a w
alk in his garden with Lady Hamilton. As they sat down on a bench, there was a
moment of passion. It was then that he discovered that AB did not equal BA.
英语意思我懂

一天,教师费曼正在讲解角动量.他正在描述他们不能交换.他这样描述“交换”的含义：一个先生和一个女士在公园里的事使这个先生明白了什么是不能交换,当他和他心上人边走边聊,当他们想坐在一个长凳上休息时,他们抑制不住,突然来了激情,在长凳上的动作证明了他们是不能交换的~
这是我自己想的,貌似未成年人读不懂,但是费曼就是这种讲课风格,可以看看下面的网页,介绍了费曼的基本情况.
没看懂
这不是物理吧.大概是讲矩阵的交换律不成立的发现.
得找个翻译来
一天，费曼在课堂上讲角动量。他讲到了角动量的矩阵表示法，并提到角动量之间不可对易。他说，是哈密顿发现了不可对易关系。一天，当哈密顿和他夫人在公园散步后，他们在长凳上休息，激情过后，他才发现了AB不等于BA。
物理？？
我只会英语，不会物理！
就是左乘和右乘不一样，
A乘以B不等于B乘以A
