"The world is full of signs and wonders, but we walk past them every day without seeing."

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.

自我只是它在成为过程中的东西。

The safest course is to do nothing against one's conscience.With this secret， we can enjoy life and have no fear from death.

To write a life is to assemble a mosaic where some pieces are inevitably missing.

创作的过程和最终的作品一样重要。
