Stephen Hawking

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.

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

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

Science is beautiful when it makes simple explanations of phenomena or connections between different observations. Examples include the double helix in biology and the fundamental equations of physics.

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

Sometimes I wonder if I'm as famous for my wheelchair and disabilities as I am for my discoveries.

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

I believe things cannot make themselves impossible.

There is no heaven or afterlife for broken-down computers that is a fairy story for people afraid of the dark.

Computers double their performance every month.

There is a real danger that computers will develop intelligence and take over. We urgently need to develop direct connections to the brain so that computers can add to human intelligence rather than be in opposition.

I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.

I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers that is a fairy story for people afraid of the dark.

I have wanted to fly into space for many years, but never imagined it would really be feasible.

Perhaps one day I will go into space.

Time can behave like another direction in space under extreme conditions.

A zero-gravity flight is a first step toward space travel.

I think the human race doesn't have a future if it doesn't go into space.
