A good mathematician should be both rigorous and imaginative.
Maybe if we knew whatother people were thinking, we'd know that no one's ordinary. And we all deservea standing ovation at least once in our lives.
大多数人的问题在于他们用希望、恐惧或愿望思考,而不是用头脑。
我唯一能做的就是诚实地面对我的不确定性。
《与邵元冲的谈话》(1919年5月20日)
在济贫院这个只有穷人和无家可归的人待的地方,死亡毕竟是一件非常平常的事。
