The book is not an end in itself, it is a means of evocation.

眼界要开阔，就要游鉴名山大川；度量应宏大，须得熟读经史典籍。

数学中发现的快乐是无与伦比的。

the only thing we have to fear is fear itself.

People are afraid to pursue their most important dreams, because they feel that they don't deserve them, or that they'll be unable to achieve them. We, their hearts, become fearful just thinking of loved ones who go away forever, or of moments that could have been good but weren't, or of treasures that might have been found but were forever hidden in the sands.

我认为数学家更像艺术家，而不是科学家。
