The first amazing fact about gravitation is that the ratio of inertial mass to gravitational mass is constant wherever we have checked it. The second amazing thing about gravitation is how weak it is.

We’ve arranged a civilization in which most crucial elements profoundly depend on science and technology.

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.

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.

In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.

Science in the modern world has many uses; its chief use, however, is to provide long words to cover the errors of the rich.

It is a profound and necessary truth that the deep things in science are not found because they are useful; they were found because it was possible to find them.

Science is the captain, and practice the soldiers.

There is a single light of science, and to brighten it anywhere is to brighten it everywhere.

In order to arrive at knowledge of the motions of birds in the air, it is first necessary to acquire knowledge of the winds, which we will prove by the motions of water in itself, and this knowledge will be a step enabling us to arrive at the knowledge of beings that fly between the air and the wind.

I’ve always been amazed by Da Vinci, because he worked out science on his own. He would work by drawing things and writing down his ideas. Of course, he designed all sorts of flying machines way before you could actually build something like that.

The history of science shows that theories are perishable. With every new truth that is revealed we get a better understanding of Nature and our conceptions and views are modified.

No matter what engineering field you’re in, you learn the same basic science and mathematics. And then maybe you learn a little bit about how to apply it.

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.

Gravitation is, so far, not understandable in terms of other phenomena.

You have a row of dominoes set up; you knock over the first one, and what will happen to the last one is that it will go over very quickly.

We want to answer this classical question, who am I? So I think that most of our works are for art, or whatever we do, including science or religion, tried to answer that question.

Change is inevitable. Change is constant.

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

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

It vexes me when they would constrain science by the authority of the Scriptures, and yet do not consider themselves bound to answer reason and experiment.

The science of psychology has been far more successful on the negative than on the positive side… It has revealed to us much about man’s shortcomings, his illnesses, his sins, but little about his potentialities, his virtues, his achievable aspirations, or his psychological health.

Science sent the Hubble telescope out into space, so it could capture light and the absence thereof, from the very beginning of time. And the telescope really did that. So now we know that there was once absolutely nothing, such a perfect nothing that there wasn’t even nothing or once.

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.

Wisdom alone is the science of other sciences.

If you are in a spaceship that is traveling at the speed of light, and you turn on the headlights, does anything happen?

Creationists make it sound as though a ‚theory‘ is something you dreamt up after being drunk all night.

My preparation is about precision. It is a science.

Shun no toil to make yourself remarkable by some talent or other; yet do not devote yourself to one branch exclusively. Strive to get clear notions about all. Give up no science entirely; for science is but one.

By denying scientific principles, one may maintain any paradox.

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.

We should not teach children the sciences; but give them a taste for them.

Science arose from poetry… when times change the two can meet again on a higher level as friends.

Science has not yet taught us if madness is or is not the sublimity of the intelligence.

To every action there is always opposed an equal reaction.

I am a great fan of science, but I cannot do a quadratic equation.

I do not believe in God; his existence has been disproved by Science. But in the concentration camp, I learned to believe in men.

The situation in the sciences is this: A concept or an idea which cannot be measured or cannot be referred directly to experiment may or may not be useful. It need not exist in a theory.

Science never solves a problem without creating ten more.

Theoretical physics is one of the few fields in which being disabled is no handicap – it is all in the mind.

Before I lost my voice, it was slurred, so only those close to me could understand, but with the computer voice, I found I could give popular lectures. I enjoy communicating science. It is important that the public understands basic science, if they are not to leave vital decisions to others.

I am not enough of a mathematician to be able to judge either the well-foundedness or the limits of relativity in physics.

Nevertheless, it is even harder for the average ape to believe that he has descended from man.

Ever since Newton, we’ve done science by taking things apart to see how they work. What the computer enables us to do is to put things together to see how they work: we’re now synthesized rather than analysed. I find one of the most enthralling aspects of computers is limitless communication.

It is theoretically possible to warp spacetime itself, so you’re not actually moving faster than the speed of light, but it’s actually space that’s moving.

Science is not everything, but science is very beautiful.

I used to think information was destroyed in black hole. This was my biggest blunder, or at least my biggest blunder in science.

Gravitation is not responsible for people falling in love.

As a Humanist, I love science. I hate superstition, which could never have given us A-bombs.

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.

What goes up must come down.

Science is the father of knowledge, but opinion breeds ignorance.

Working out another system to replace Newton’s laws took a long time because phenomena at the atomic level were quite strange. One had to lose one’s common sense in order to perceive what was happening at the atomic level.

Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man’s struggle for good and evil seems inadequate.

The mineral world is a much more supple and mobile world than could be imagined by the science of the ancients. Vaguely analogous to the metamorphoses of living creatures, there occurs in the most solid rocks, as we now know, perpetual transformation of a mineral species.

Life is tragic. You are tiny and flawed and ignorant and weak, and everything else is huge, complex, and overwhelming.

It is a curious thing: man, the centre and creator of all science, is the only object which our science has not yet succeeded in including in a homogeneous representation of the universe. We know the history of his bones, but no ordered place has yet been found in nature for his reflective intelligence.

I’ve always been very one-sided about science, and when I was younger, I concentrated almost all my effort on it.

I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy.

Science can lift people out of poverty and cure disease. That, in turn, will reduce civil unrest.

Evolution was far more thrilling to me than the biblical account. Who would not rather be a rising ape than a falling angel? To my juvenile eyes, Darwin was proved true every day. It doesn’t take much to make us flip back into monkeys again.
