In my school, the brightest boys did math and physics, the less bright did physics and chemistry, and the least bright did biology. I wanted to do math and physics, but my father made me do chemistry because he thought there would be no jobs for mathematicians.

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.

Not only does God play dice, but... he sometimes throws them where they cannot be seen.

We are all now connected by the Internet, like neurons in a giant brain.

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

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.

Stephen Hawking

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

My advice to other disabled people would be, concentrate on things your disability doesn't prevent you doing well, and don't regret the things it interferes with. Don't be disabled in spirit as well as physically.

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.

Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks.

Stephen Hawking

We are in danger of destroying ourselves by our greed and stupidity. We cannot remain looking inwards at ourselves on a small and increasingly polluted and overcrowded planet.

When one's expectations are reduced to zero, one really appreciates everything one does have.

Life would be tragic if it weren't funny.

The past, like the future, is indefinite and exists only as a spectrum of possibilities.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code.

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

Stephen Hawking

Science Knowledge Very

Nothing cannot exist forever.

Stephen Hawking

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.

Stephen Hawking

Someone told me that each equation I included in the book would halve the sales.

Stephen Hawking

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.

Stephen Hawking

God not only plays dice, He also sometimes throws the dice where they cannot be seen.

Stephen Hawking

Stem cell research is the key to developing cures for degenerative conditions like Parkinson's and motor neuron disease from which I and many others suffer. The fact that the cells may come from embryos is not an objection, because the embryos are going to die anyway.

Stephen Hawking

If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.

Stephen Hawking

To confine our attention to terrestrial matters would be to limit the human spirit.

Stephen Hawking

I am just a child who has never grown up. I still keep asking these 'how' and 'why' questions. Occasionally, I find an answer.

Stephen Hawking

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.

Stephen Hawking

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.

Stephen Hawking

I wouldn't be here today if it were not for the NHS. I have received a large amount of high-quality treatment without which I would not have survived.

Stephen Hawking

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

Stephen Hawking

There could be shadow galaxies, shadow stars, and even shadow people.

Stephen Hawking

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

Stephen Hawking

People who boast about their I.Q. are losers.

Stephen Hawking

We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.

Stephen Hawking

While physics and mathematics may tell us how the universe began, they are not much use in predicting human behavior because there are far too many equations to solve. I'm no better than anyone else at understanding what makes people tick, particularly women.

Stephen Hawking

In my school, the brightest boys did math and physics, the less bright did physics and chemistry, and the least bright did biology. I wanted to do math and physics, but my father made me do chemistry because he thought there would be no jobs for mathematicians.

Stephen Hawking

I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off. Theoretically, it could be re-created on a neural network, but that would be very difficult, as it would require all one's memories.

Stephen Hawking

I don't think the human race will survive the next thousand years, unless we spread into space.

Stephen Hawking

Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global nuclear war, a genetically engineered virus or other dangers we have not yet thought of.

Stephen Hawking

Because there is a law such as gravity, the universe can and will create itself from nothing.

Stephen Hawking

A few years ago, the city council of Monza, Italy, barred pet owners from keeping goldfish in curved bowls... saying that it is cruel to keep a fish in a bowl with curved sides because, gazing out, the fish would have a distorted view of reality. But how do we know we have the true, undistorted picture of reality?

Stephen Hawking

Keeping an active mind has been vital to my survival, as has been maintaining a sense of humor.

Stephen Hawking

We are all different. There is no such thing as a standard or run-of-the-mill human being, but we share the same human spirit.

Stephen Hawking

There is no unique picture of reality.

Stephen Hawking

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

Stephen Hawking

Women. They are a complete mystery.

No one undertakes research in physics with the intention of winning a prize. It is the joy of discovering something no one knew before.
