"The truth is rarely pure and never simple."

你们的聪明才智必定会派上用场，因为你们将在一片充满奇迹的土地上行进。我们人类，尽管跬步前行，却终将令自己大吃一惊。我们能够想方设法制造清洁能源，也能够一个原子一个原子地组装微型机械，使之穿过细胞壁，然后修复细胞。这个月，有一个异常而不可避免的事情发生了——人类终于合成了生命。在未来几年，我们不仅会合成生命，还会按说明书驱动它们。我相信你们甚至会看到我们理解人类的大脑，儒勒·凡尔纳，马克·吐温，伽利略，牛顿——所有那些充满好奇之心的人都希望能够活到现在。作为文明人，我们会拥有如此之多的天赋，就像是坐在我面前的你们，每一个生命个体都拥有许多独特的天赋。

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.

世间万物有盛衰，人生安得常少年。

数学之美只会向更有耐心的追随者展现。

The beauty of mathematics only shows itself to more patient followers.

彼得·拉克斯

有人说，世上所有的东西都可以量化，唯有感情不行。其实，感情也是可以量化的，量化就是一本书的厚度。

刘震云

操作可以练，但意识是天赋加努力。

The whole art of teaching is only the art of awakening the natural curiosity of young minds for the purpose of satisfying it afterwards.

教学的全部艺术，不过是唤醒年轻人天生的好奇心，以便日后满足它。
