What I have learned from life is to make the most of what you have got.

If I have questions about the universe on my mind when I go to bed, I can't turn off. I dream equations all night.

So Einstein was wrong when he said, "God does not play dice." Consideration of black holes suggests, not only that God does play dice, but that he sometimes confuses us by throwing them where they can't be seen.

It often happens that I have an idea, but then I try to fill in the intermediate steps and find they don't work, so I have to give it up.

At times, I get very lonely because people are afraid to talk to me or don't wait for me to write a response. I'm shy and tongue-tied at times. I find it difficult to talk to people who I don't know.

Science can explain the universe without the need for a Creator.

I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off. Theoretically, it could be re-created on a neural network, but that would be very difficult, as it would require all one's memories.
