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.
Stephen Hawking
Intelligence is the ability to adapt to change.
Stephen Hawking
People won’t have time for you if you are always angry or complaining.
Stephen Hawking
We are all now connected by the Internet, like neurons in a giant brain.
Stephen Hawking
However difficult life may seem, there is always something you can do and succeed at.
Stephen Hawking
The past, like the future, is indefinite and exists only as a spectrum of possibilities.
Stephen Hawking
Scientists have become the bearers of the torch of discovery in our quest for knowledge.
Stephen Hawking
Science is not only a disciple of reason but, also, one of romance and passion.
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
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.

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
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
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.
Stephen Hawking
Life would be tragic if it weren’t funny.
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
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
As scientists, we step on the shoulders of science, building on the work that has come before us – aiming to inspire a new generation of young scientists to continue once we are gone.
Stephen Hawking
I believe things cannot make themselves impossible.
Stephen Hawking
Although September 11 was horrible, it didn’t threaten the survival of the human race, like nuclear weapons do.
Stephen Hawking
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.
Stephen Hawking
Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.
Stephen Hawking
Work gives you meaning and purpose and life is empty without it.
Stephen Hawking
There is no unique picture of reality.
Stephen Hawking
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.
Stephen Hawking
If aliens visit us, the outcome would be much as when Columbus landed in America, which didn’t turn out well for the Native Americans.
Stephen Hawking
Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill.
Stephen Hawking
I’m an atheist.
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 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
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.
Stephen Hawking
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
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.
Stephen Hawking
I was never top of the class at school, but my classmates must have seen potential in me, because my nickname was ‘Einstein.’
Stephen Hawking
It is generally recognised that women are better than men at languages, personal relations and multi-tasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics.
Stephen Hawking
If I had to choose a superhero to be, I would pick Superman. He’s everything that I’m not.
Stephen Hawking
There could be shadow galaxies, shadow stars, and even shadow people.
Stephen Hawking
Not only does God play dice, but… he sometimes throws them where they cannot be seen.
Stephen Hawking
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.
Stephen Hawking
Only black holes of very low mass would emit a significant amount of radiation.
Stephen Hawking
The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C – not much good for defrosting the pizza, let alone cooking it.
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
To my mathematical brain, the numbers alone make thinking about aliens perfectly rational. The real challenge is to work out what aliens might actually be like.
Stephen Hawking
I hope I have helped to raise the profile of science and to show that physics is not a mystery but can be understood by ordinary people.
Stephen Hawking
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.
Stephen Hawking
We should seek the greatest value of our action.
Stephen Hawking
I don’t have much positive to say about motor neuron disease, but it taught me not to pity myself because others were worse off, and to get on with what I still could do. I’m happier now than before I developed the condition.
Stephen Hawking
One can’t predict the weather more than a few days in advance.
Stephen Hawking
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.
Stephen Hawking
Up until the 1920s, everyone thought the universe was essentially static and unchanging in time.
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
There is no physical law precluding particles from being organised in ways that perform even more advanced computations than the arrangements of particles in human brains.
Stephen Hawking
We live in a bewildering world.
