世界不是由思想或想象力运行的，而是由意见运行的。

Sun don't shine forever.

时光飞逝，应珍惜每一刻。

能源转型不仅仅是化石燃料向可再生能源的转变，更是使整个能源系统更加可持续。

Your smarts will come in handy because you will travel in a land of marvels. We humans -- plodding as we are -- will astonish ourselves. We'll invent ways to generate clean energy and a lot of it. Atom by atom， we'll assemble tiny machines that will enter cell walls and make repairs. This month comes the extraordinary but also inevitable news that we've synthesized life. In the coming years， we'll not only synthesize it， but we'll engineer it to specifications. I believe you'll even see us understand the human brain. Jules Verne， Mark Twain， Galileo， Newton -- all the curious from the ages would have wanted to be alive most of all right now. As a civilization， we will have so many gifts， just as you as individuals have so many individual gifts as you sit before me.

Fame is not the goal. The goal is the art.

柏拉图是我的朋友，亚里士多德是我的朋友，但我最伟大的朋友是真理。
