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.

Writing is a way of exorcising the demons that haunt us.

The challenge of creating efficient and selective catalysts keeps me motivated every day.

Don't be afraid of failure, be afraid that you don't even dare to try.

有些鸟是注定不会被关在笼子里，因为它们的每一片羽毛都闪耀着自由的光辉。
