It matters if you don't just give up.
It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.
Working with my father [] is a great thrill - he has the amazing ability to hold enormous amounts of information in his head.
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.
I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.
The question is: is the way the universe began chosen by God for reasons we can't understand, or was it determined by a law of science? I believe the second. If you like, you can call the laws of science 'God', but it wouldn't be a personal God that you could meet, and ask questions.
Inspiring quotes and messsages
One might think this means that imaginary numbers are just a mathematical game having nothing to do with the real world. From the viewpoint of positivist philosophy, however, one cannot determine what is real. All one can do is find which mathematical models describe the universe we live in. It turns out that a mathematical model involving imaginary time predicts not only effects we have already observed but also effects we have not been able to measure yet nevertheless believe in for other reasons. So what is real and what is imaginary? Is the distinction just in our minds?
Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space.
Or in other words, why does disorder increase in the same direction of time as that in which the universe expands?
The human failing I would most like to correct is aggression,
I think that it's important for scientists to explain their work, particularly in cosmology. This now answers many questions once asked of religion.
We could call order by the name of God, but it would be an impersonal God. There's not much personal about the laws of physics.
My expectations were reduced to zero when I was 21. Everything since then has been a bonus.
The victim should have the right to end his life, if he wants. But I think it would be a great mistake. However bad life may seem, there is always something you can do, and succeed at. While there's life, there is hope.
If we can avoid disaster for the next two centuries, our species should be safe as we spread into space. If we are the only intellegent beings in the galaxy we should make sure we survive and continue. . . . Our only chance of long-term survival is not to remain inward looking on planet Earth but to spread out into space. We have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space.
Think of our DNA. In the last million years, our DNA hasn't changed at all. It's really much the same as it was in the jungle, a million, two millions years ago. But in the last 200 years, our destructive capacities have increased many, many millions of times over. Why don't we see intelligent signals from outer space? Because in all likelihood, once the civilization reaches the point our civilization has reached, it destroys itself.
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.
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.
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.
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.
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.
When i try more inspiring quote
What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary.
Time and space are finite in extent, but they don't have any boundary or edge. They would be like the surface of the earth, but with two more dimensions.

Keeping an active mind has been vital to my survival, as has been maintaining a sense of humor.
Intelligence is the ability to adapt to change.
Science is not only a disciple of reason but, also, one of romance and passion.
People won't have time for you if you are always angry or complaining.
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.
I was never top of the class at school, but my classmates must have seen potential in me, because my nickname was 'Einstein.'
It was Einstein's dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein's day hadn't made enough progress in understanding the forces of nature for that to be a realistic goal.
So long as the universe had a beginning, we could suppose it had a creator. But if the universe is really completely self-contained, having no boundary or edge, it would have neither beginning nor end: it would simply be. What place, then, for a creator?
Single day is enough inspiring quotes
There is no heaven or afterlife for broken-down computers; that is a fairy story for people afraid of the dark.
'The Simpsons' appearances were great fun. But I don't take them too seriously. I think 'The Simpsons' have treated my disability responsibly.
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.
Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a 'crank.'
We are the product of quantum fluctuations in the very early universe.
You have to pay for what you do
The universe is not indifferent to our existence - it depends on it.
There's no way to remove the observer - us - from our perceptions of the world.
The Paralympic Games is about transforming our perception of the world.
Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe?
I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves.
I am in touch with a company that hopes to replicate my voice. However, they are not replicating my original voice - if they did that, I would sound like a man in his 20s, which would be very strange! They are actually trying to replicate the synthesizer that sits on my wheelchair.
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.
I have found far greater enthusiasm for science in America than here in Britain. There is more enthusiasm for everything in America.
We won't know for a few years.
Science makes god unnecessary.
The increase of disorder or entropy is what distinguishes the past from the future, giving a direction to time.
Please join me in applauding the ESA - European Space Agency's historic efforts with the Rosetta Mission and landing a spacecraft on rotating comet. It may seem like a work of fiction, but it is very real, very impressive, and will help us to further uncover the mysteries surrounding the formation of the solar system. They made a beautiful short film using an imaginary landscape to illustrate today's historic feat.
The idea of 10 dimensions might sound exciting, but they would cause real problems if you forget where you parked your car.
It is impossible to imagine a four-dimensional space. I personally find it hard enough to visualize a three-dimensional space!
[Asked what he thinks about most during the day] Women. They are a complete mystery.
I like physics, but I love cartoons.
Matter of profile dignity quotes
We don't let animals suffer, so why humans?
The universe does not behave according to our pre-conceived ideas. It continues to surprise us.
Remember to 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. And however difficult life may seem, there is always something you can do and succeed at. It matters that you don't just give up.
We find ourselves in a bewildering world. We want to make sense of what we see around us and to ask: What is the nature of the universe? What is our place in it and where did it and we come from? Why is it the way it is?
Now, radical forward thinking is offering hope for the future: Replacement body parts to order. A team of scientists in California believe that if you can design them on a computer, you should be able to print them out.
When I get to heaven I'm gonna find the guy in charge of the weather and kick his rear.
At times, I get very lonely because people are afraid to talk to me or don't wait for me to write a response. I'm shy and tongue-tied at times. I find it difficult to talk to people who I don't know.
We explore because we are human.
I think computer viruses should count as life,
It matters that you don't just give up,
Religion believes in miracles, but these aren't compatible with science.
I'm the archetype of a disabled genius, or should I say a physically challenged genius, to be politically correct. At least I'm obviously physically challenged. Whether I'm a genius is more open to doubt.
Someone told me that each equation I included in the book would halve the sales. I therefore resolved not to have any equations at all. In the end, however, I did put in one equation, Einstein's famous equation,. I hope that this will not scare off half of my potential readers.
Don't be disabled in spirit as well as physically.
The lesson of the book is that the universe is governed by the laws of science.
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.
Selish world emotional quote
When I was first diagnosed with ALS, I was given two years to live. Now 45 years later, I am doing pretty well.
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.

Look up at the stars, not down at your feet.
You cannot understand the glories of the universe without believing there is some Supreme Power behind it.
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.
We think that life develops spontaneously on Earth, so it must be possible for life to develop on suitable planets elsewhere in the universe. But we don't know the probability that a planet develops life.
According to 'M' theory, ours is not the only universe. Instead, 'M' theory predicts that a great many universes were created out of nothing.
Philosophers have not kept up with modern developments in science. Particularly physics.
Exploration by real people inspires us.
There could be shadow galaxies, shadow stars, and even shadow people.
What was God doing before the divine creation?
I had not expected 'A Brief History of Time' to be a best seller.
There is nothing bigger or older than the universe.
Up until the 1920s, everyone thought the universe was essentially static and unchanging in time.
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.
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.
there is no prescribed route to follow to arrive at a new idea. You have to make the intuitive leap. But the difference is that once you've made the intuitive leap you have to justify it by filling in the intermediate steps. N my case, it often happens that I have an idea, but then I try to fill in the intermediate steps and find that they don't work, so I have to give it up.
I have experimental evidence that time travel is not possible.
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.
If you are lucky enough to find love, remember it is there and don't throw it away.
Science is beautiful when it makes simple explanations of phenomena or connections between different observations.
thus, in a sense, we are all doomed. even if we stay away from black holes
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.
Real science can be far stranger than science fiction and much more satisfying.
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
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.
Of course it is possible that UFO's really do contain aliens as many people believe, and the government is hushing it up
lesson of life quote
lesson of life quote
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.
Disability need not be an obstacle to success.

Not only does God play dice, but he sometimes throws them where they cannot be seen.
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.
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.
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.
Succeed in spite of management.
The fact that no one understands you doesn't mean you're an artist.
Do you ever wonder how much deeper the ocean would be without sponges?
I'd say I don't believe in God, but I'm afraid He might hear me.
When something is made idiot proof, they will just make better idiots.
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.
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.
If I knew what was going to happen in ten years I would do it now. I just follow my nose.
What is important is that we have the ability to create.
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.
Chaos, when left alone, tends to multiply.
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.
Many badly needed goals, like fusion and cancer cure, would be achieved much sooner if we invested more [in scientific education and research].
If I have questions about the universe on my mind when I go to bed, I can't turn off. I dream equations all night.
God is not to blame
God is not to blame
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.
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.
We are entering an increasingly dangerous period of our history. But I'm an optimist.
We shouldn't be surprised that conditions in the universe are suitable for life, but this is not evidence that the universe was designed to allow for life. We could call order by the name of God, but it would be an impersonal God. There's not much personal about the laws of physics.
In a world that is in chaos politically, socially and environmentally, how can the human race sustain another 100 years?
I think the next century will be the century of complexity.
I think it would be a disaster. The extraterrestrials would probably be far in advance of us. The history of advanced races meeting more primitive people on this planet is not very happy, and they were the same species. I think we should keep our heads low.
So next time someone complains that you have made a mistake, tell him that may be a good thing. Because without imperfection, neither you nor I would exist.
The intelligent beings in these regions should therefore not be surprised if they observe that their locality in the universe satisfies the conditions that are necessary for their existence. It is a bit like a rich person living in a wealthy neighborhood not seeing any poverty.
When one's expectations are reduced to zero, one really appreciates everything one does have
I have sold more books on physics than Madonna has on sex. [Hawking adopted this statement from a remark made to him by his former post-doc, Nathan Myhrvold.]
[Question: What do you think was the most important physics idea to emerge this year?] We won't know for a few years.
I am damned if I'm going to die before I have unraveled more of the universe
Someone told me that each equation I included in my book would halve the sales. I did put in one equation, Einstein's famous equation, E = MC squared. I hope that this will not scare off half of my potential readers.
