A mathematician is a person who can find analogies between theorems; a better mathematician is one who can see analogies between theories and the best mathematician can notice analogies between analogies.
数学家是能在定理间找到类比的人;更好的数学家能在理论间看到类比;而最优秀的数学家能注意到类比之间的类比。
译文:学习不以广博为贵,贵在学得正确,说话不以漂亮动听为贵,贵在表达得当。赏析:读书求学要走正道,要有正确的学习观,不能学习旁门左道。和别人交往,说话不一定要动听,一定要正确表达,不要出口伤人。
我们生活在一个人们根据他们最坏的行为而不是最好的行为来评判的世界。
