Not only does God play dice, but... he sometimes throws them where they cannot be seen.
I had not expected 'A Brief History of Time' to be a best seller. It was my first popular book and aroused a great deal of interest. Initially, many people found it difficult to understand. I therefore decided to try to write a new version that would be easier to follow.
Theology is unnecessary.
We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.
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.
God not only plays dice, but also sometimes throws them where they cannot be seen.
My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.
All my adult life people have been helping me.
Wagner manages to convey emotion with music better than anyone, before or since.
In less than a hundred years, we have found a new way to think of ourselves. From sitting at the center of the universe, we now find ourselves orbiting an average-sized sun, which is just one of millions of stars in our own Milky Way galaxy.
One cannot really argue with a mathematical theorem.
I think those who have a terminal illness and are in great pain should have the right to choose to end their own life, and those that help them should be free from prosecution.
I believe everyone should have a broad picture of how the universe operates and our place in it. It is a basic human desire. And it also puts our worries in perspective.
We live in a bewildering world.
Our minds work in real time, which begins at the Big Bang and will end, if there is a Big Crunch - which seems unlikely, now, from the latest data showing accelerating expansion. Consciousness would come to an end at a singularity.
Theoretical physics is one of the few fields in which being disabled is no handicap - it is all in the mind.
I entered the health care debate in response to a statement in the United States press in summer 2009 which claimed the National Health Service in Great Britain would have killed me off, were I a British citizen. I felt compelled to make a statement to explain the error.
What I'd really like to control is not machines, but people.
As Irving Good realised in 1965, machines with superhuman intelligence could repeatedly improve their design even further, triggering what Vernor Vinge called a 'singularity.'
Because there is a law such as gravity, the universe can and will create itself from nothing.
Before we understand science, it is natural to believe that God created the universe.
Up until the 1920s, everyone thought the universe was essentially static and unchanging in time.
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.
Some forms of motor neuron disease are genetically linked, but I have no indication that my kind is. No other member of my family has had it. But I would be in favour of abortion if there was a high risk.
Science is not only a disciple of reason but, also, one of romance and passion.
It is not clear that intelligence has any long-term survival value.
There's no way to remove the observer - us - from our perceptions of the world.
My work and my family are very important to me.
As a child, I wanted to know how things worked and to control them. With a friend, I built a number of complicated models that I could control.
If I had a time machine, I'd visit Marilyn Monroe in her prime or drop in on Galileo as he turned his telescope to the heavens.
My discovery that black holes emit radiation raised serious problems of consistency with the rest of physics. I have now resolved these problems, but the answer turned out to be not what I expected.
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 in universal health care. And I am not afraid to say so.
My first popular book, 'A Brief History of Time,' aroused a great deal of interest, but many found it difficult to understand.
We are all now connected by the Internet, like neurons in a giant brain.
There is no heaven or afterlife for broken-down computers; that is a fairy story for people afraid of the dark.
