真正的喜悦精神、崇高感、超越人类的感觉，这是最高卓越的试金石，在数学中肯定能找到，就像在诗歌中一样。
The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry.
The spiritual life does not remove us from the world but leads us deeper into it.
Trust is built when actions align with words.
当天赋不努力时，努力会击败天赋。
当你看起来最轻松时，往往是你最担忧的时候。
