Quotes by Physicists - Page 21

In fact, for a period stretching over seven hundred years, the international language of science was Arabic. For this was the language of the Qur'an, the holy book of Islam, and thus the official language of the vast Islamic Empire that, by the early eighth century CE, stretched from India to Spain.
Jim Al-Khalili
Gandhi, the greatest political genius of our time, has pointed the way. He was shown of what sacrifices people are capable once they have found the right way. His work for the liberation of India is a living testimony to the fact that a will governed by firm conviction is stronger than a seemingly invincible material power.
Albert Einstein
To say that science is logical is like saying that a painting is paint.
Leon Cooper
A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible.
Freeman Dyson
Do not imagine that mathematics is hard and crabbed, and repulsive to common sense. It is merely the etherealization of common sense.
William Thomson
According to inflation, the more than 100 billion galaxies, sparkling throughout space like heavenly diamonds, are nothing but quantum mechanics writ large across the sky. To me, this realization is one of the greatest wonders of the modern scientific age.
Brian Greene
We have a closed circle of consistency here: the laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it.
Roger Penrose
Universe consists of frozen light.
David Bohm
Politics is for the moment and equation is for eternity.
Albert Einstein
The whole [scientific] process resembles biological evolution. A problem is like an ecological niche, and a theory is like a gene or a species which is being tested for viability in that niche.
David Deutsch
For me, I think the greatest achievements of science is to allow humanity to realize that our world is comprehensible. Through science, rational thinking, we can understand how the universe works.
Jim Al-Khalili
It’s hard to build models of inflation that don't lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously.
Alan Guth
The steam engine has done much more for science than science has done for the steam engine.
William Thomson
If and when all the laws governing physical phenomena are finally discovered, and all the empirical constants occurring in these laws are finally expressed through the four independent basic constants, we will be able to say that physical science has reached its end, that no excitement is left in further explorations, and that all that remains to a physicist is either tedious work on minor details or the self-educational study and adoration of the magnificence of the completed system. At that stage physical science will enter from the epoch of Columbus and Magellan into the epoch of the National Geographic Magazine!
George Gamow
How came the bodies of animals to be contrived with so much art, and for what ends were their several parts?Was the eye contrived without skill in Opticks, and the ear without knowledge of sounds?...and these things being rightly dispatch’d, does it not appear from phænomena that there is a Being incorporeal, living, intelligent...?
Isaac Newton
Blind metaphysical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things which we find suited to different times and places could arise from nothing but the ideas and will of a Being, necessarily existing.
Isaac Newton
The human race is just a chemical scum on a moderate-sized planet, orbiting around a very average star in the outer suburb of one among a hundred billion galaxies. We are so insignificant that I can't believe the whole universe exists for our benefit. That would be like saying that you would disappear if I closed my eyes.
Stephen Hawking
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
If we are seeking to serve the God of truth then we should really welcome truth from whatever source it comes. We shouldn’t fear the truth. Some of it will be from science, obviously, but by no means all of it. It will sometimes by perplexing, how this bit of truth relates to that bit of truth; we know that within science itself often enough and we find it outside of science as well. The crucial thing is to be honest.
John Polkinghorne
If you thought you were trying to find out more about it because you're gonna get an answer to some deep philosophical question...you may be wrong! It may be that you can't get an answer to that particular question by finding out more about the character of nature. But my interest in science is to simply find out about the world.
Richard Feynman
We have been led to imagine all sorts of things infinitely more marvelous than the imagining of poets and dreamers of the past. It shows that the imagination of nature is far, far greater than the imagination of man. For instance, how much more remarkable it is for us all to be stuck-half of us upside down-by a mysterious attraction, to a spinning ball that has been swinging in space for billions of years, than to be carried on the back of an elephant supported on a tortoise swimming in a bottomless sea.
Richard Feynman
[Doubt] is not a new idea; this is the idea of the age of reason. This is the philosophy that guided the men who made the democracy that we live under. The idea that no one really knew how to run a government led to the idea that we should arrange a system by which new ideas could be developed, tried out, and tossed out if necessary, with more new ideas bought in - a trial-and-error system. This method was a result of the fact that science was already showing itself to be a successful venture at the end of the eighteenth century. Even then it was clear to socially minded people that the openness of possibilities was an opportunity, and that doubt and discussion were essential to progress into the unknown. If we want to solve a problem that we have never solved before, we must leave the door to the unknown ajar...doubt is not to be feared, but welcomed and discussed.
Richard Feynman
Science is my territory, but science fiction is the landscape of my dreams.
Freeman Dyson
Those distinct substances, which concretes generally either afford, or are made up of, may, without very much inconvenience, be called the elements or principles of them.
Robert Boyle
Give me the positions and velocities of all the particles in the universe, and I will predict the future.
Marquis Pierre Simon de Laplace
It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but five billion years to make man!
George Gamow
The essential fact which emerges ... is that the three smallest and most active reservoirs ( of carbon in the global carbon cycle), the atmosphere, the plants and the soil, are all of roughly the same size. This means that large human disturbance of any one of these reservoirs will have large effects on all three. We cannot hope either to understand or to manage the carbon in the atmosphere unless we understand and manage the trees and the soil too.
Freeman Dyson
A synthesis embracing both rational understanding and the mystical experience of unity is the mythos, spoken or unspoken, or our present day and age.
Wolfgang Pauli
The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy.
Steven Weinberg
Now I am become death, the destroyer of worlds. (quoting the Bhagavad-Gita after witnessing the first Nuclear explosion.)
J. Robert Oppenheimer
When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarely, in your thoughts advanced to the stage of science.
William Thomson
I have not yet lost a feeling of wonder, and of delight, that this delicate motion should reside in all the things around us, revealing itself only to him who looks for it. I remember, in the winter of our first experiments, just seven years ago, looking on snow with new eyes. There the snow lay around my doorstep — great heaps of protons quietly precessing in the earth's magnetic field. To see the world for a moment as something rich and strange is the private reward of many a discovery.
Edward M. Purcell
The people who actually make the advances in theoretical physics don't think in these categories that the philosophers and the historians of science subsequently invent for them
Stephen Hawking
Outside our consciousness there lies the cold and alien world of actual things. Between the two stretches the narrow borderland of the senses. No communication between the two worlds is possible excepting across the narrow strip. For a proper understanding of ourselves and of the world, it is of the highest importance that this borderland should be thoroughly explored.”Heinrich Hertz’ Keynote Address at the Imperial Palace, Berlin, August, 1891
Heinrich Hertz
[Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So I hope you can accept nature as She is - absurd.
Richard Feynman
I'm comfortable with the unknown -- that's the point of science. There are places out there, billions of places out there, that we know nothing about. And the fact that we know nothing about them excites me, and I want to go out and find out about them.And that's what science is.So I think if you’re not comfortable with the unknown, then it’s difficult to be a scientist… I don’t need an answer. I don’t need answers to everything. I want to have answers to find.
Brian Cox
I don't believe that math and nature respond to democracy. Just because very clever people have rejected the role of the infinite, their collective opinions, however weighty, won't persuade mother nature to alter her ways. Nature is never wrong.
Janna Levin
...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance.
Brian Greene
It is of great advantage to the student of any subject to read the original memoirs on that subject, for science is always most completely assimilated when it is in the nascent state...
James Clerk Maxwell
Try and penetrate with our limited means the secrets of nature and you will find that, behind all the descernible laws and connections, there remains something subtle, intangible and inexplicable. Veneration for this force beyond anything that we can comprehend is my religion. To that extent I am, in fact, religious.
Albert Einstein
If your experiment needs a statistician, you need a better experiment.
Ernest Rutherford
The world keeps happening, in accordance with its rules; it's up to us to make sense of it and give it value.
Sean Carroll
The successful development of science requires a proper balance to be maintained between the method of building up from observations and the method of deducing by pure reasoning from speculative assumptions.
Paul A.M. Dirac
Something else gets under your skin, keeps you working days and nights at the sacrifice of your sleeping and eating and attention to your family and friends, something beyond the love of puzzle solving. And that other force is the anticipation of understanding something about the world that no one has ever understood before you.Einstein wrote that when he first realized that gravity was equivalent to acceleration -- an idea that would underlie his new theory of gravity -- it was the "happiest thought of my life." On projects of far smaller weight, I have experienced that pleasure of discovering something new. It is an exquisite sensation, a feeling of power, a rush of the blood, a sense of living forever. To be the first vessel to hold this new thing.All of the scientists I've known have at least one more quality in common: they do what they do because they love it, and because they cannot imagine doing anything else. In a sense, this is the real reason a scientist does science. Because the scientist must. Such a compulsion is both blessing and burden. A blessing because the creative life, in any endeavor, is a gift filled with beauty and not given to everyone, a burden because the call is unrelenting and can drown out the rest of life.This mixed blessing and burden must be why the astrophysicist Chandrasekhar continued working until his mid-80's, why a visitor to Einstein's apartment in Bern found the young physicist rocking his infant with one hand while doing mathematical calculations with the other. This mixed blessing and burden must have been the "sweet hell" that Walt Whitman referred to when he realized at a young age that he was destined to be a poet. "Never more," he wrote, "shall I escape.
Alan Lightman
Scientists, therefore, are responsible for their research, not only intellectually but also morally. This responsibility has become an important issue in many of today's sciences, but especially so in physics, in which the results of quantum mechanics and relativity theory have opened up two very different paths for physicists to pursue. They may lead us - to put it in extreme terms - to the Buddha or to the Bomb, and it is up to each of us to decide which path to take.
Fritjof Capra
All that was required to measure the planet was a man with a stick and a brain. In other words, couple an intellect with some experimental apparatus and almost anything seems achievable.
Simon Singh
Understanding requires insight. Insight must be anchored.
Brian Greene
In 1963, when I assigned the name "quark" to the fundamental constituents of the nucleon, I had the sound first, without the spelling, which could have been "kwork." Then, in one of my occasional perusals of Finnegans Wake, by James Joyce, I came across the word "quark" in the phrase "Three quarks for Muster Mark." Since "quark" (meaning, for one thing, the cry of a gull) was clearly intended to rhyme with "Mark," as well as "bark" and other such words, I had to find an excuse to pronounce it as "kwork." But the book represents the dreams of a publican named Humphrey Chimpden Earwicker. Words in the text are typically drawn from several sources at once, like the "portmanteau words" in Through the Looking Glass. From time to time, phrases occur in the book that are partially determined by calls for drinks at the bar. I argued, therefore, that perhaps one of the multiple sources of the cry "Three quarks for Muster Mark" might be "Three quarts for Mister Mark," in which case the pronunciation "kwork" would not be totally unjustified. In any case, the number three fitted perfectly the way quarks occur in nature.
Murray Gell-Mann
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.
Stephen Hawking
Whenever we proceed from the known into the unknown we may hope to understand, but we may have to learn at the same time a new meaning of the word 'understanding.
Werner Heisenberg
I have no responsibility to live up to what others expect of me. That's their mistake, not my failing.
Richard Feynman
An experiment is a question which science poses to Nature and a measurement is the recording of Nature's answer.
Max Planck
I have been in my bed for five weeks, oppressed with weakness and other infirmities from which my age, seventy four years, permits me not to hope release. Added to this (proh dolor! [O misery!]) the sight of my right eye — that eye whose labors (dare I say it) have had such glorious results — is for ever lost. That of the left, which was and is imperfect, is rendered null by continual weeping.
Galileo Galilei
It was quite the most incredible event that has ever happened to me in my life. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hi
Ernest Rutherford
One of the great achievements of science has been, if not to make it impossible for intelligent people to be religious, then at least to make it possible for them not to be religious. We should not retreat from this accomplishment.
Steven Weinberg
New scientific ideas never spring from a communal body, however organized, but rather from the head of an individually inspired researcher who struggles with his problems in lonely thought and unites all his thought on one single point which is his whole world for the moment.
Max Planck
Names and attributes must be accommodated to the essence of things, and not the essence to the names, since things come first and names afterwards.
Galileo Galilei
It is our task, both in science and in society at large, to prove the conventional wisdom wrong and to make our unpredictable dreams come true
Freeman Dyson
Today the network of relationships linking the human race to itself and to the rest of the biosphere is so complex that all aspects affect all others to an extraordinary degree. Someone should be studying the whole system, however crudely that has to be done, because no gluing together of partial studies of a complex nonlinear system can give a good idea of the behavior of the whole.
Murray Gell-Mann
The assumption of an absolute determinism is the essential foundation of every scientific enquiry.
Max Planck
