I don't regret anything I've done.
我不后悔我做的任何事情。
Nature has evolved incredible mechanisms for sensing the world - we're just starting to decode them.
Be realistic, demand the impossible!
The present state of the system of nature is evidently a consequence of what it was in the preceding moment, and if we conceive of an intelligence which at a given instant comprehends all the relations of the entities of this universe, it could state the respective positions, motions, and general effects of all these entities at any time in the past or future.
I'm not a role model, I'm a role player.
I must learn to be content with being happier than I deserve.
