Man is the measure of all things: of things which are, that they are, and of things which are not, that they are not.
人是万物的尺度:对于存在的事物,它们存在;对于不存在的事物,它们不存在。
眼睛同时看两样东西,就会看不明白;耳朵同时听两种声音,就会听不清楚。
I don’t care what you think unless it’s about me.
The real challenge is not in solving the equations, but in understanding what the solutions mean.
