The fact that no one understands you doesn't mean you're an artist.

Disorder increases with time because we measure time in the direction in which disorder increases.

So next time someone complains that you have made a mistake, tell him that may be a good thing. Because without imperfection, neither you nor I would exist.

It would be very difficult to explain why the universe should have begun in just this way, except as the act of a God who intended to create beings like us.

The question is: is the way the universe began chosen by God for reasons we can't understand, or was it determined by a law of science? I believe the second. If you like, you can call the laws of science 'God', but it wouldn't be a personal God that you could meet, and ask questions.

I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.

To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.
