人类的选择在于自由和幸福之间,而对于大多数人来说,幸福更好。
The choice for mankind lies between freedom and happiness and for the great bulk of mankind, happiness is better.
It's not about being the best, it's about being better than you were yesterday.
Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding.
I like things that are simple and easy to understand.
The computer is just a tool. The pencil is also a tool. It's about how you use it.
