在数学中,提出问题的艺术必须比解决问题更有价值。
In mathematics, the art of proposing a question must be held of higher value than solving it.
There are no mistakes in art, only unexpected discoveries.
The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny...'
The best way to predict the future is to invent it.
富贵不能使我的思想迷乱,贫贱不能使我改变志向,威武不能使我节操屈服,这样的人才称得上大丈夫。
