Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding.
数学不是关于数字、方程、计算或算法的:它是关于理解的。
伟大的科学需要聪明的头脑和谦逊的心。
成功不在于你赚了多少钱,而在于你对人们生活的影响。
I never think about the future. It comes soon enough.
I think the most important thing is to be honest and truthful with what you say and what you do.
