My father was a research scientist in tropical medicine, so I always assumed I would be a scientist, too. I felt that medicine was too vague and inexact, so I chose physics. Stephen Hawking

This required abandoning the idea that there is a universal quantity called time that all clocks measure. Instead, everyone would have his own personal time. The clocks of two people would agree if they were at rest with respect to each other but not if they were moving. This has been confirmed by a number of experiments, including one in which an extremely accurate timepiece was flown around the world and then compared with one that had stayed in place. If you wanted to live longer, you could keep flying to the east so the speed of the plane added to the earth Stephen Hawking

I have experimental evidence that time travel is not possible. Stephen Hawking

We believe human begins have existed for only a small fraction of cosmic history, because human race has been improving so rapidly in knowledge and technology that if people had been around for millions of years, the human race would be much further along in it's mastery. Stephen Hawking

As those who have seen Jurassic Park will know, this means a tiny disturbance in one place, can cause a major change in another. A butterfly flapping its wings can cause rain in Central Park, New York. The trouble is, it is not repeatable. The next time the butterfly flaps its wings, a host of other things will be different, which will also influence the weather. That is why weather forecasts are so unreliable. Stephen Hawking

Disability need not be an obstacle to success. Stephen Hawking
Download Wallpaper:

A theory is a good theory if it satisfies two requirements: it must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations. Stephen Hawking
Download Wallpaper:

But a machine that was powerful enough to accelerate particles to the grand unification energy would have to be as big as the Solar System - and would be unlikely to be funded in the present economic climate. Stephen Hawking
Download Wallpaper:

If I knew what was going to happen in ten years I would do it now. I just follow my nose. Stephen Hawking
Download Wallpaper:

One can't prove that God doesn't exist, but science makes God unnecessary. The laws of physics can explain the universe without the need for a creator. Stephen Hawking
Download Wallpaper:

You may see a cup of tea fall off a table and break into pieces on the floor... But you will never see the cup gather itself back together and jump back on the table. The increase of disorder, or entropy, is what distinguishes the past from the future, giving a direction to time. Stephen Hawking

[Question: Do you feel that scientists correct themselves as often as they should?] More often than politicians, but not as often as they should. Stephen Hawking
Download Wallpaper:

All the evidence shows that God was actually quite a gambler, and the universe is a great casino, where dice are thrown, and roulette wheels spin on every occasion. Over a large number of bets, the odds even out and we can make predictions; that's why casino owners are so rich. But over a very small number of rolls of the dice, the uncertainty principle is very important. Stephen Hawking

So great a contribution to physics was Two New Sciences that scholars have long maintained that the book anticipated Isaac Newton's laws of motion. Stephen Hawking
Download Wallpaper:

What is important is that we have the ability to create. Stephen Hawking
Download Wallpaper:

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. But our genetic code still carries the selfish and aggressive instincts that were of survival advantage in the past. It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million. Our only chance of long term survival, is not to remain inward looking on planet Earth, but to spread out into space. Stephen Hawking

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory. Stephen Hawking
Download Wallpaper:

So Einstein was wrong when he said, God does not play dice. Consideration of black holes suggests, not only that God does play dice, but that he sometimes confuses us by throwing them where they can't be seen. Stephen Hawking
Download Wallpaper:

I used to think that information was destroyed in black holes. But the AdS/CFT correspondence led me to change my mind. This was my biggest blunder, or at least my biggest blunder in science. Stephen Hawking
Download Wallpaper:

Maybe that is our mistake: maybe there are no particle positions and velocities, but only waves. It is just that we try to fit the waves to our preconceived ideas of positions and velocities.The resulting mismatch is the cause of the apparent unpredictability. Stephen Hawking
Download Wallpaper:

To show this diagram properly, I would really need a four dimensional screen. However, because of government cuts, we could manage to provide only a two dimensional screen. Stephen Hawking
Download Wallpaper:

If what we regard as real depends on our theory, how can we make reality the basis of our philosophy? ...But we cannot distinguish what is real about the universe without a theory...it makes no sense to ask if it corresponds to reality, because we do not know what reality is independent of a theory. Stephen Hawking

Ever since the dawn of civilization, people have not been content to see events as unconnected and inexplicable. They have craved an understanding of the underlying order in the world. Today we still yearn to know why we are here and where we came from. Humanity's deepest desire for knowledge is justification enough for our continuing quest. And our goal is nothing less than a complete description of the universe we live in. Stephen Hawking

A model is a good model if first it interprets a wide range of observations in terms of a simple and elegant model, and second if the model makes definite predictions that can be tested, and possibly falsified, by observation. Stephen Hawking

Chaos, when left alone, tends to multiply. Stephen Hawking
Download Wallpaper:

In A Brief History Of Time I used the word "God" like Einstein did as a shorthand for the laws of physics. However, this is not what most people mean by God, so I have decided not to use the term. The laws of physics can explain the universe without the need for a God. Stephen Hawking

One does not have to appeal to God to set the initial conditions for the creation of the universe, but if one does He would have to act through the laws of physics. Stephen Hawking
Download Wallpaper:

If the total energy of the universe must always remain zero, and it costs energy to create a body, how can a whole universe be created from nothing? Stephen Hawking
Download Wallpaper:

Not to take this web of dualities as a sign we are on the right track would be a bit like believing that God put fossils into the rocks in order to mislead Darwin about the evolution of life. Stephen Hawking

But how do we know we have the true, undistorted picture of reality? Stephen Hawking

It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years. Stephen Hawking

I can't say that my disability has helped my work, but it has allowed me to concentrate on research without having to lecture or sit on boring committees. Stephen Hawking
Download Wallpaper:

The missing link in cosmology is the nature of dark matter and dark energy. Stephen Hawking

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing? Stephen Hawking
Download Wallpaper:

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin. Stephen Hawking
