Cosmology is a rapidly advancing field.

What goes on inside a star is better understood than one might guess from the difficulty of having to look at a little dot of light through a telescope, because we can calculate what the atoms in the stars should do in most circumstances.

I grew up with the biologists. I know how they think.

Space has always fascinated me. As a young boy looking up at the stars, I found it impossible to resist thinking what was out there and if I ever would experience space first-hand.

There is neither spirit nor matter in the world. The stuff of the universe is spirit-matter. No other substance but this could have produced the human molecule.

It stands to the everlasting credit of science that by acting on the human mind it has overcome man’s insecurity before himself and before nature.

Facts are stubborn, but statistics are more pliable.

Millions of people were inspired by the Apollo Program. I was five years old when I watched Apollo 11 unfold on television, and without any doubt it was a big contributor to my passions for science, engineering, and exploration.

I was not an anthropology student prior to the war. I took it up as part of a personal readjustment following some bewildering experiences as an infantryman and later as a prisoner of war in Dresden, Germany. The science of the Study of Man has been extremely satisfactory from that personal standpoint.

My son likes to go see mines and electric plants, or the Large Hadron Collider, and we’ve had a chance to see a lot of interesting stuff.

Among physicists, I’m respected I hope.

Many badly needed goals, like fusion and cancer cure, would be achieved much sooner if we invested more.

If anyone offers conjectures about the truth of things from the mere possibility of hypotheses, I do not see by what stipulation anything certain can be determined in any science, since one or another set of hypotheses may always be devised which will appear to supply new difficulties.

God writes the Gospel not in the Bible alone, but also on trees, and in the flowers and clouds and stars.

The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth.

We are the product of quantum fluctuations in the very early universe.

It’s time for the human race to enter the solar system.

My first popular book, ‚A Brief History of Time,‘ aroused a great deal of interest, but many found it difficult to understand.

Today’s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.

Even sleepers are workers and collaborators in what goes on in the Universe.

We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.

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

In the material sciences these are and have been, and are most surely likely to continue to be heroic days.

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.

Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.

I am a little too absorbed by science to be able to philosophise much; but the more I look into myself, the more I find myself possessed by the conviction that it is only the science of Christ running through all things, that is to say true mystical science, that really matters. I let myself get caught up in the game when I geologise.

Politics is a science. You can demonstrate that you are right and that others are wrong.

I’m concerned that my technical skills have advanced to the point where I can get closer to what I’m aiming for, which is not such a good thing.

Quarks came in a number of varieties – in fact, at first, only three were needed to explain all the hundreds of particles and the different kinds of quarks – they are called u-type, d-type, s-type.

The clearest way into the Universe is through a forest wilderness.

I first had the idea of writing a popular book about the universe in 1982. My intention was partly to earn money to pay my daughter’s school fees.

Every living being is an engine geared to the wheelwork of the universe. Though seemingly affected only by its immediate surrounding, the sphere of external influence extends to infinite distance.

They say the universe is expanding. That should help with the traffic.

Our existence is beyond our explanation, whether we believe in God or we have religion or we’re atheist. Our existence is beyond our understanding. No one has an answer.

The universe may have a purpose, but nothing we know suggests that, if so, this purpose has any similarity to ours.

I’m an atheist, and the concept of god for me is all part of what I call ‚the last illusion.‘ The last illusion is someone knows what is going on. Nearly everyone has that illusion somewhere, and it manifests not only in the terms of the idea that there is a god but that it knows what’s going on but that the planets know what’s going on.

You and I are all as much continuous with the physical universe as a wave is continuous with the ocean.

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.

The greatest progress is in the sciences that study the simplest systems. So take, say, physics – greatest progress there. But one of the reasons is that the physicists have an advantage that no other branch of sciences has. If something gets too complicated, they hand it to someone else.

Science and fiction both begin with similar questions: What if? Why? How does it all work? But they focus on different areas of life on earth.

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.

For NASA, space is still a high priority.

Space is almost infinite. As a matter of fact, we think it is infinite.

When I was researching my book ‚The 33 Strategies of War‘, I studied Napoleon extensively and I found myself wanting to ask Napoleon questions about things he did, and if was I interpreting his actions correctly.

If that’s there, I believe that technology will probably step up to their part of it.

Love is an adventure and a conquest. It survives and develops, like the universe itself, only by perpetual discovery.

Science must have originated in the feeling that something was wrong.

It now appears that the way the universe began can indeed be determined, using imaginary time.

Science is what you know, philosophy is what you don’t know.

Time can behave like another direction in space under extreme conditions.

Even with cameras being very cheap, one thing that researchers noticed was that you look really bad in a videoconference image because the lighting is bad and you get shadows and things.

We have to build the capacity of our institutions, employees and workers. Our regulatory environment has not been encouraging to research, innovation and enterprise.

I got into science fiction by being interested in astronomy first.

We are the miracle of force and matter making itself over into imagination and will. Incredible. The Life Force experimenting with forms. You for one. Me for another. The Universe has shouted itself alive. We are one of the shouts.

The media need superheroes in science just as in every sphere of life, but there is really a continuous range of abilities with no clear dividing line.

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?

Science is magic that works.

Understanding science and pushing the boundaries of science is what makes me immensely satisfied.

I like to talk about lint and coasters, the expansion of the universe and maybe McDonald’s. I’m completely turned off by the idea of politics.

I’m astounded by people who want to ‚know‘ the universe when it’s hard enough to find your way around Chinatown.

A man will turn over half a library to make one book.
