I think the human race has no future if it doesn't go into space.

There is no unique picture of reality.

We've created life in our own image.

For millions of years, mankind lived just like the animals. Then something happened which unleashed the power of our imagination. We learned to talk and we learned to listen.

Some people would claim that things like love, joy and beauty belong to a different category from science and can't be described in scientific terms, but I think they can now be explained by the theory of evolution.

Equations are just the boring part of mathematics. I attempt to see things in terms of geometry.

If I knew what was going to happen in ten years I would do it now. I just follow my nose.
