"So remember to look up at the stars and not down at your feet. Try to make sense of what you see and hold on to that childlike wonder about what makes the universe exist."
"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."

"Quiet people have the loudest minds."
"Intelligence is the ability to adapt to change."
"The thing about smart people is that they seem like crazy people to dumb people."
"It is my view that the simplest explanation is there is no God. No one created the universe and no one directs our fate. This leads me to a profound realization. There is probably no heaven, and no afterlife either. We have this one life to appreciate the grand design of the universe, and for that, I am extremely grateful."
"It is all right to make mistakes; nothing is perfect because with perfection, we would not exist."
