The initial configuration of the universe may have been chosen by God, or it may itself have been determined by the laws of science. In either case, it would seem that everything in the universe would then be determined by evolution according to the laws of science, so it is difficult to see how we can be masters of our fate.

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.

It is said that there's no such thing as a free lunch. But the universe is the ultimate free lunch.

We see the universe the way it is because we exist.

There are plenty of dead scientists I admire, but I can't think of any living ones. This is probably because it is only in retrospect that one can see who made the important contributions.

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

Quiet people have the loudest minds.
