一个好的数学问题的定义是它产生的数学,而不是问题本身。
The definition of a good mathematical problem is the mathematics it generates rather than the problem itself.
You do not need to leave your room. Remain sitting at your table and listen. Do not even listen, simply wait. Do not even wait, be quite still and solitary. The world will freely offer itself to you to be unmasked, it has no choice, it will roll in ecstasy at your feet.
注意你的思想,因为它们将变成言辞;注意你的言辞,因为它们将变成行动;注意你的行动,因为它们将变成习惯;注意你的习惯,因为它们将变成性格;注意你的性格,因为它们将决定你的命运。 我们想的是什么,就会成为什么样的人。
Beauty is about the experience.
