"There is no substitute for books in the life of a child."
There is no exquisite beauty… without some strangeness in the proportion.
"Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding."
预测未来的最好方法就是去发明它。
世界是美丽的,但它有一种叫做人类的疾病。
The world is full of broken stories, waiting to be mended.
