We must develop as quickly as possible technologies that make possible a direct connection between brain and computer, so that artificial brains contribute to human intelligence rather than opposing it.

I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.

Intelligence is the ability to adapt to change.

I'm never any good in the morning. It is only after four in the afternoon that I get going.

I was born on January 8, 1942, exactly three hundred years after the death of Galileo. I estimate, however, that about two hundred thousand other babies were also born that day. I don't know whether any of them was later interested in astronomy.

I'm not afraid of death, but I'm in no hurry to die. I have so much I want to do first.

Before I lost my voice, it was slurred, so only those close to me could understand, but with the computer voice, I found I could give popular lectures. I enjoy communicating science. It is important that the public understands basic science, if they are not to leave vital decisions to others.

I believe there are no questions that science can't answer about a physical universe.

If you believe in science, like I do, you believe that there are certain laws that are always obeyed.

Before we understand science, it is natural to believe that God created the universe.

I have found far greater enthusiasm for science in America than here in Britain. There is more enthusiasm for everything in America.

Science is increasingly answering questions that used to be the province of religion.

Science can lift people out of poverty and cure disease. That, in turn, will reduce civil unrest.

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

Throughout history, people have studied pure science from a desire to understand the universe rather than practical applications for commercial gain. But their discoveries later turned out to have great practical benefits.

In the past, there was active discrimination against women in science. That has now gone, and although there are residual effects, these are not enough to account for the small numbers of women, particularly in mathematics and physics.

I believe the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws.

God may exist, but science can explain the universe without the need for a creator.
