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.

心灵是驾驭现实的工具。

你或许无法改变现实，但你可以改变对现实的态度。

The only way to make sense out of change is to plunge into it, move with it, and join the dance.

遗忘就是背叛，铭记就是抵抗。

The problem of the modern age is the problem of the individual's self-preservation in the face of the overwhelming power of the social mechanism.
