Stephen Hawking

Work gives you meaning and purpose and life is empty without it.

Women. They are a complete mystery.

If we do discover a complete theory, it should be in time understandable in broad principle by everyone. Then we shall all, philosophers, scientists, and just ordinary people be able to take part in the discussion of why we and the universe exist.

People won't have time for you if you are always angry or complaining.

I used to think information was destroyed in black hole. This was my biggest blunder, or at least my biggest blunder in science.

The media need superheroes in science just as in every sphere of life, but there is really a continuous range of abilities with no clear dividing line.

Philosophers have not kept up with modern developments in science. Particularly physics.

Science predicts that many different kinds of universe will be spontaneously created out of nothing. It is a matter of chance which we are in.

The universe is governed by science. But science tells us that we can't solve the equations, directly in the abstract.

Science is not only a disciple of reason but, also, one of romance and passion.

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.

There are grounds for cautious optimism that we may now be near the end ofthe search for the ultimate laws of nature.

I enjoy all forms of music - pop, classical and opera.

It is generally recognised that women are better than men at languages, personal relations and multi-tasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics.

Scientists have become the bearers of the torch of discovery in our quest for knowledge.

It is not clear that intelligence has any long-term survival value.

Among physicists, I'm respected I hope.

The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.
