A mathematician is a person who can find analogies between theorems; a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.
数学家是能在定理之间找到类比的人;更好的数学家是能在证明之间看到类比的人;而最好的数学家是能注意到理论之间类比的人。
宽容大量容一切之物,站稳立场做人;踏实的地方站立,稳当之处着手。
当下总是不稳定的地方,而过去是我们自以为知道身在何处的地方。
