"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。
It is not the voice that commands the story; it is the ear.
I'm not afraid to die, I'm afraid of not trying.
In a world filled with hate, we must still dare to hope. In a world filled with anger, we must still dare to comfort. In a world filled with despair, we must still dare to dream. In a world filled with distrust, we must still dare to believe.
预测未来的最好方法就是创造未来。
