Almost everything that distinguishes the modern world from earlier centuries is attributable to science, which achieved its most spectacular triumphs in the seventeenth century.

Some day science may have the existence of mankind in power, and the human race can commit suicide by blowing up the world.

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.

The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.

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.

If you believe in science, like I do, you believe that there are certain laws that are always obeyed.

Poets say science takes away from the beauty of the stars – mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?

There is no conflict between the ideal of religion and the ideal of science, but science is opposed to theological dogmas because science is founded on fact. To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine.

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

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?

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.

Have we not come to such an impasse in the modern world that we must love our enemies – or else? The chain reaction of evil – hate begetting hate, wars producing more wars – must be broken, or else we shall be plunged into the dark abyss of annihilation.

Democracy is the art and science of running the circus from the monkey cage.

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

Before we understand science, it is natural to believe that God created the universe.

Science may have found a cure for most evils; but it has found no remedy for the worst of them all – the apathy of human beings.

In order for the United States to do the right things for the long term, it appears to be helpful for us to have the prospect of humiliation. Sputnik helped us fund good science – really good science: the semiconductor came out of it.

New discoveries in science will continue to create a thousand new frontiers for those who still would adventure.

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

I’m never going to go to Mars, but I’ve helped inspire, thank goodness, the people who built the rockets and sent our photographic equipment off to Mars.

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.

Men love to wonder, and that is the seed of science.

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

Whether one welcomes or deplores it, nothing is more surely and exactly characteristic of modern times than the irresistible invasion of the human world by technology. Mechanism invading like a tide all the places of the earth and all forms of social activity.

When I began in 1960, individuality wasn’t an accepted thing to look for; it was about species-specific behaviour. But animal behaviour is not hard science. There’s room for intuition.

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.

Aviation offered such fun as crossing the continent in planes large and small, trying the whirling rotors of an autogiro, making record flights. With these activities came opportunity to know women everywhere who shared my conviction that there is so much women can do in the modern world and should be permitted to do irrespective of their sex.

I feel like the thing we can do is celebrate people doing great work and create more cultural momentum and awareness that this is an important thing in the world. So when the next economic crisis hits and people are talking about where to cut from the budget, science isn’t the thing.

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.

Science never makes things that do not have to do with what we feel, by which I mean what we want and what we fear.

As soon as questions of will or decision or reason or choice of action arise, human science is at a loss.

Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe.

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.

The whole of science is nothing more than a refinement of everyday thinking.

The study and knowledge of the universe would somehow be lame and defective were no practical results to follow.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‚Eureka!‘ but ‚That’s funny…‘

Science and mindfulness complement each other in helping people to eat well and maintain their health and well-being.

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

The work of science is to substitute facts for appearances, and demonstrations for impressions.

The American doctor, in my opinion, possesses a combination of conservatism and that other quality which has put the United States in the forefront in almost every department of science – that is, an eagerness to know what it is really all about in order that he may not be the one left behind if there is something to it.

The capacity of the female mind for studies of the highest order cannot be doubted, having been sufficiently illustrated by its works of genius, of erudition, and of science.

The credit of advancing science has always been due to individuals and never to the age.

I have a big following among the biogeeks of this world. Nobody ever puts them in books.

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.

Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone.

Religion is something left over from the infancy of our intelligence, it will fade away as we adopt reason and science as our guidelines.

The pursuit of science leads only to the insoluble.

Cosmology is a rapidly advancing field.

Part of the reason that our politics seems so tough right now and facts and science and argument does not seem to be winning the day all the time is because we’re hardwired not to always think clearly when we’re scared. And the country’s scared.

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

If we do discover a complete theory, it should be in time understandable in broad principle by everyone. Then we shall all, philosophers, scientists, and just ordinary people be able to take part in the discussion of why we and the universe exist.

Fiction is not necessarily about what you know, it’s about how you feel. That is the truth about fiction, and the other truth is that all science is a tool, and we use our tools not to actualise what we know, but to implement how we feel.

My message to the Americans is the same as to everyone – that is to unite behind the science and to act on the science.

Science, as everyone knows, is responsible, moderate, unsentimental, and otherwise good.

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

The universe is governed by science. But science tells us that we can’t solve the equations, directly in the abstract.

There is nothing which can better deserve your patronage, than the promotion of science and literature. Knowledge is in every country the surest basis of public happiness.

He who possesses art and science has religion; he who does not possess them, needs religion.

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

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