The study of mathematics is like air or gravity – it’s everywhere, even if you don’t see it.

You can't go back home to your family, back home to your childhood, back home to romantic love, back home to a young man's dreams of glory and of fame, back home to exile, to escape to Europe and some foreign land, back home to lyricism, to singing just for singing's sake, back home to aestheticism, to one's youthful idea of 'art' and beauty, back home to the ivory tower, back home to places in the country, to the cottage in Bermuda, away from all the strife and conflict of the world, back home to the father you have lost and have been looking for, back home to someone who can help you, save you, ease the burden for you, back home to the old forms and systems of things which once seemed everlasting but which are changing all the time—back home to the escapes of Time and Memory.

嫉妒在今日是一种禁忌话题，但这个社会上最普遍的感受，便是嫉妒。嫉妒来自生而平等的精神。

The only thing that can make you happy is your own smile.
