The past, like the future, is indefinite and exists only as a spectrum of possibilities.
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 believe in universal health care. And I am not afraid to say so.
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...
As Irving Good realised in 1965, machines with superhuman intelligence could repeatedly improve their design even further, triggering what Vernor Vinge called a 'singularity.'
What place, then, for a creator?
Associates and collaborators were Roger Penrose,
I have found far greater enthusiasm for science in America than here in Britain. There is more enthusiasm for everything in America.
I have wanted to fly into space for many years, but never imagined it would really be feasible.
I believe in the possible. I believe, small though we are, insignificant though we may be, we can reach a full understanding of the universe. You were right when you said you felt small, looking up at...
Scientists have become the bearers of the torch of discovery in our quest for knowledge.
We lived in a tall, narrow Victorian house, which my parents had bought very cheaply during the war, when everyone thought London was going to be bombed flat. In fact, a V-2 rocket landed a few houses...
I used to think information was destroyed in black hole. This was my biggest blunder, or at least my biggest blunder in science.
I don't have much positive to say about motor neurone disease. But it taught me not to pity myself because others were worse off, and to get on with what I could still do.
A zero-gravity flight is a first step toward space travel.
Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.
Before 1915, space and time were thought of as a fixed arena in which events took place, but which was not affected by what happened in it. Space and time are now dynamic quantities... space and time...
I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.
Look up at the stars and not down at your feet. Try to make sense of what you see, and wonder about what makes the universe exist. Be curious.
