In a world that is in chaos politically, socially and environmentally, how can the human race sustain another 100 years? - Stephen Hawking

I think that when we die we return to dust. But there’s a sense in which we live on, in our influence, and in our genes that we pass on to our children. We have this one life to appreciate the grand design of the universe, and for that I am extremely grateful.

Quiet people have the loudest minds.

I have noticed that even those who assert that everything is predestined and that we can change nothing about it still look both ways before they cross the street.
