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.
The motor of our ingenuity is the question ‘Does it have to be like this?’, from which arise political reforms, scientific developments, improved relationships, better books.
The key to great acting is not to pretend, but to become.
