我们弦论教授的表达能力真的非常令人迷惑……比如今天讲课的时候,有同学问他某个 Chevally-Eilenberg complex 上面的 differential 表达式是怎么 dictate 出来的,他嗯嗯啊啊了半天,不知道在嘟囔些啥。我看不下去了,举手接话说:"By respecting the Lie algebra representation and antisymmetry from Wedge products, as well as requiring Q to be a nilpotent, we should probably obtain a unique expression in terms of the basis of our complex." 教授双手合十充满感激地看着我说:“Yes, exactly, that's perfect, thank you!” 把我给整不会了,心想这种来自 typical physicist 的 sloppy 发言为什么会得到如此盛赞,他在组织语言方面是否过于无助了……
@QuantumBubbleTea 好厉害啊!!!!!
