Quotes by Physicists - Page 3

I would not think that philosophy and reason themselves will be man's guide in the foreseeable future; however, they will remain the most beautiful sanctuary they have always been for the select few.

Albert Einstein

Underneath his sweetness and gentleness was the heat of a volcano. [Michael Faraday] was a man of excitable and fiery nature; but through high self-discipline he had converted the fire into a central glow and motive power of life, instead of permitting it to waste itself in useless passion.

John Tyndall

I made this [letter] very long, because I did not have the leisure to make it shorter.

Blaise Pascal

... though he [Michael Faraday] took no cities, he captivated all hearts.

John Tyndall

If your experiment needs a statistician, you need a better experiment.

Ernest Rutherford

Imagination is the highest form of research.

Albert Einstein

Physicists love this number not just because it is dimensionless, but also because it is a combination of three fundamental constants of nature. Why do these constants come together to make the particular number 1/137.036 and not some other number?

John Archibald Wheeler

If you want people to think well of you do not speak well of yourself.

Blaise Pascal

If you can't explain it to a six year old, you don't understand it yourself.

Albert Einstein

The strength of the Constitution lies entirely in the determination of each citizen to defend it. Only if every single citizen feels duty bound to do his share in this defense are the constitutional rights secure.

Albert Einstein

I think nature's imagination Is so much greater than man's, she's never going to let us relax

Richard Feynman

The steam engine has done much more for science than science has done for the steam engine.

William Thomson

Personally I think there is no doubt that sub-atomic energy is available all around us, and that one day man will release and control its almost infinite power. We cannot prevent him from doing so and can only hope that he will not use it exclusively in blowing up his next door neighbour. (1936)

Francis William Aston

my first recommendation to people in charge of science education is, more money for public libraries and museums. Public libraries and museums ought to be as common as schools.

Freeman Dyson

This crippling of individuals I consider the worst evil of capitalism. Our whole educational system suffers from this evil. An exaggerated competitive attitude is inculcated into the student, who is trained to worship acquisitive success as a preparation for his future career.

Albert Einstein

There's a kind of saying that you don't understand its meaning, 'I don't believe it. It's too crazy. I'm not going to accept it.'… You'll have to accept it. It's the way nature works. If you want to know how nature works, we looked at it, carefully. Looking at it, that's the way it looks. You don't like it? Go somewhere else, to another universe where the rules are simpler, philosophically more pleasing, more psychologically easy. I can't help it, okay? If I'm going to tell you honestly what the world looks like to the human beings who have struggled as hard as they can to understand it, I can only tell you what it looks like.

Richard Feynman

There are only certain intervals of time when life of any sort is possible in an expanding universe and we can practise astronomy only during that habitable time interval in cosmic history.

John D. Barrow

It is not clear that intelligence has any long-term survival value.

Stephen Hawking

The Pharisees had an ethic of avoidance, and Jesus had an ethic of involvement.

Mark Buchanan

The air around you is filled with floating atoms, sliding down the Earth's spacetime curve. Atoms first assembled in the cores of long-dead stars. Atoms within you, everywhere, disintegrating in radioactive decays. Beneath your feet, the floor - whose electrons refuse to let yours pass, thus making you able to stand and walk and run. Earth, your planet, a lump of matter made out of the three quantum fields known to mankind, held together by gravity, the so-called fourth force (even though it isn't a force), floating within and through spacetime.

Christophe Galfard

Once you can accept the universe as matter expanding into nothing that is something, wearing stripes with plaid comes easy.

Albert Einstein

There are three sources of belief: reason, custom, inspiration.

Blaise Pascal

Author wonders whether God's proclamation of His natural mastery when appearing to Job might be about restoring a sense of wonder to world-weary man as much as humbling him.

Mark Buchanan

Einstein's paper on the photoelectric effect was the work for which he ultimately won the Nobel Prize. It was published in 1905, and Einstein has another paper in the very same journal where it appeared - his other paper was the one that formulated the special theory of relativity. That's what it was like to be Einstein in 1905; you publish a groundbreaking paper that helps lay the foundation of quantum mechanics, and for which you later win the Nobel Prize, but it's only the second most important paper that you publish in that issue of the journal.

Sean Carroll

I noticed that the [drawing] teacher didn't tell people much... Instead, he tried to inspire us to experiment with new approaches. I thought of how we teach physics: We have so many techniques - so many mathematical methods - that we never stop telling the students how to do things. On the other hand, the drawing teacher is afraid to tell you anything. If your lines are very heavy, the teacher can't say, "Your lines are too heavy." because *some* artist has figured out a way of making great pictures using heavy lines. The teacher doesn't want to push you in some particular direction. So the drawing teacher has this problem of communicating how to draw by osmosis and not by instruction, while the physics teacher has the problem of always teaching techniques, rather than the spirit, of how to go about solving physical problems.

Richard Feynman

A true genius admits that he/she knows nothing.

Albert Einstein

Thank you very Much, I enjoyed myself

Richard Feynman

For instance, the scientific article may say, 'The radioactive phosphorus content of the cerebrum of the rat decreases to one- half in a period of two weeks.' Now what does that mean?It means that phosphorus that is in the brain of a rat—and also in mine, and yours—is not the same phosphorus as it was two weeks ago. It means the atoms that are in the brain are being replaced: the ones that were there before have gone away.So what is this mind of ours: what are these atoms with consciousness? Last week's potatoes! They now can remember what was going on in my mind a year ago—a mind which has long ago been replaced. To note that the thing I call my individuality is only a pattern or dance, that is what it means when one discovers how long it takes for the atoms of the brain to be replaced by other atoms. The atoms come into my brain, dance a dance, and then go out—there are always new atoms, but always doing the same dance, remembering what the dance was yesterday.

Richard Feynman

It is this mythical, or rather symbolic, content of the religious traditions which is likely to come into conflict with science. This occurs whenever this religious stock of ideas contains dogmatically fixed statements on subjects which belong in the domain of science.

Albert Einstein

One might be led to question whether the scientists acted wisely in presenting the statesmen of the world with this appalling problem. Actually there was no choice. Once basic knowledge is acquired, any attempt at preventing its fruition would be as futile as hoping to stop the earth from revolving around the sun.

Enrico Fermi

The evolution of the human race will not be accomplished in the ten thousand years of tame animals, but in the million years of wild animals, because man is, and always will be, a wild animal.

Charles Galton Darwin

It seems to me that the idea of a personal God is an anthropological concept which I cannot take seriously. I also cannot imagine some will or goal outside the human sphere... Science has been charged with undermining morality, but the charge is unjust. A man's ethical behavior should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.

Albert Einstein

Gravitation is not responsible for people falling in love.

Albert Einstein

When we stand, we do so not only for ourselves, but also for countless others who have similar stories but may never have an opportunity to be witnessed.

William Keepin

I rate enthusiasm even above professional skill.

Sir Edward Appleton

The religious geniuses of all ages have been distinguished by this kind of religious feeling, which knows no dogma and no God conceived in man's image; so that there can be no church whose central teachings are based on it. Hence it is precisely among the heretics of every age that we find men who were filled with this highest kind of religious feeling and were in many cases regarded by their contemporaries as atheists, sometimes also as saints. Looked at in this light, men like Democritus, Francis of Assisi, and Spinoza are closely akin to one another.

Albert Einstein

Life isn't worth living, unless it is lived for someone else.

Albert Einstein

I believe in the possible. I believe, small though we are, insignificant though we may be, we can reach a full understanding of the universe. You were right when you said you felt small, looking up at all that up there. We are very, very small, but we are profoundly capable of very, very big things.

Stephen Hawking

An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.

Francis Crick

One increasingly hears rumors of a reconciliation between science and religion. In major news magazines as well as at academic conferences, the claim is made that that belief in the success of science in describing the workings of the world is no longer thought to be in conflict with faith in God. I would like to argue against this trend, in favor of a more old-fashioned point of view that is still more characteristic of most scientists, who tend to disbelieve in any religious component to the workings of the universe.

Sean Carroll

The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain.

Nikola Tesla

Black holes are where God divided by zero.

Albert Einstein

I want a man who knows something about himself. And is appalled. And has to forgive himself to get along.

C.P. Snow

Strange is our situation here upon earth. Each of us comes for a short visit, not knowing why, yet sometimes seeming to a divine purpose. From the standpoint of daily life, however, there is one thing we do know: That we are here for the sake of other men —above all for those upon whose smile and well-being our own happiness depends, for the countless unknown souls with whose fate we are connected by a bond of sympathy. Many times a day, I realize how much my outer and inner life is built upon the labors of people, both living and dead, and how earnestly I must exert myself in order to give in return as much as I have received and am still receiving.

Albert Einstein

For the place God calls us into isn’t doubt free—how can any place where we walk by faith and not by sight be that? No, the holy wild is where we have driving and haunting doubts, God-hungry doubts that pull us to our knees, force us to the Word, make us wrestle all night and not let go until He blesses us. The holy wild throngs with true skeptics.

Mark Buchanan

When I see the blind and wretched state of men, when I survey the whole universe in its deadness, and man left to himself with no light, as though lost in this corner of the universe without knowing who put him there, what he has to do, or what will become of him when he dies, incapable of knowing anything, I am moved to terror, like a man transported in his sleep to some terrifying desert island, who wakes up quite lost, with no means of escape. Then I marvel that so wretched a state does not drive people to despair.

Blaise Pascal

The fundamental laws of the universe which correspond to the two fundamental theorems of the mechanical theory of heat.1. The energy of the universe is constant.2. The entropy of the universe tends to a maximum.

Rudolf Clausius

A person functioning exclusively in the Cartesian mode may be free from manifest symptoms but cannot be considered mentally healthy. Such individuals typically lead ego-centred, competitive, goal-oriented lives. Overpreoccupied with their past and their future, they tend to have a limited awarenessof the present and thus a limited ability to derive satisfaction from ordinary activities in everyday life. They concentrate on manipulating the external world and measure their living standard by the quantity of material possessions, while they become ever more alienated from their inner world and unable to appreciate the process of life. For people whose existence is dominated by this mode of experience no level of wealth, power, or fame will bring genuine satisfaction

Fritjof Capra

I have only made this letter longer because I have not had the time to make it sho

Blaise Pascal

He who is in love with himself has at least this advantage he won't encounter many rivals.

G. C. Lichtenberg

(On the energy radiated by the Sun)It's four hundred million million million million watts. That is a million times the power consumption of the United States every year, radiated in one second, and we worked that out by using some water, a thermometer, a tin, and an umbrella. And that's why I love physics.

Brian Cox

Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it.

Richard Feynman

The important thing in science is not so much to obtain new facts as to discover new ways of thinking about them

William Lawrence Bragg

Individual events. Events beyond law. Events so numerous and so uncoordinated that, flaunting their freedom from formula, they yet fabricate firm form.

John Archibald Wheeler

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.

Richard Feynman

The fact that no limits exist to the destructiveness of this weapon [the 'Super', i.e. the hydrogen bomb] makes its very existence and the knowledge of its construction a danger to humanity as a whole. It is necessarily an evil thing considered in any light. For these reasons, we believe it important for the President of the United States to tell the American public and the world what we think is wrong on fundamental ethical principles to initiate the development of such a weapon.

Enrico Fermi

When Einstein died, his greatest rival, Bohr, found for him words of moving admiration. When a few years later Bohr in turn died, someone took a photograph of the blackboard in his study. There’s a drawing on it. A drawing of the ‘light-filled box’ in Einstein’s thought experiment. To the very last, the desire to challenge oneself and understand more. And to the very last: doubt

Carlo Rovelli

Now I know what the atom looks like.

Ernest Rutherford

Continuity in everything is unpleasant.

Blaise Pascal

The Theory of Relativity confers an absolute meaning on a magnitude which in classical theory has only a relative significance: the velocity of light. The velocity of light is to the Theory of Relativity as the elementary quantum of action is to the Quantum Theory: it is its absolute core.
