Quotes & Sayings About Theory Of Relativity

The Relativity theory, the copernican upheaval, or any great scientific convulsion, leaves a new landscape. There is a period of stunned dreariness; then people begin, antlike, the building of a new human world. They soon forget the last disturbance. But from these shocks they derive a slightly augmented vocabulary, a new blind spot in their vision, a few new blepharospasms or tics, and perhaps a revised method of computing time. — Wyndham Lewis

Here the attention of the research workers is primarily directed to the problem of reconciling the claims of the special relativity theory with those of the quantum theory. The extraordinary advances made in this field by Dirac ... leave open the question whether it will be possible to satisfy the claims of the two theories without at the same time determining the Sommerfeld fine-structure constant. — Werner Heisenberg

I can accept the theory of relativity as little as I can accept the existence of atoms and other such dogmas. — Ernst Mach

I believe that I have really found the relationship between gravitation and electricity, assuming that the Miller experiments are based on a fundamental error. Otherwise, the whole relativity theory collapses like a house of cards. — Albert Einstein

General relativity is the cornerstone of cosmology and astrophysics. It has also provided the conceptual basis for string theory and other attempts to unify all the forces of nature in terms of geometrical structures. — Paul Davies

Which is to say that culture is not a reflex of political economy, but
that society is now a reflex of key shifts in music theory and practice ...
[Sampladelia is] the sound made by those early-twentieth-century discoveries
in particle physics and relativiity theory, the projection of the minds of
Einstein, Heisenbery, and Bohr, their fateful explorations of liquid time,
curving space, uncertainty fields and relativity theorems, into densely
configured and fully ambivalent android music tracks — Arthur Kroker

There was a young lady of Wight Who travelled much faster than light. She departed one day, In a relative way, And arrived on the previous night. The point is that the theory of relativity says that there is no unique measure of time that all observers will agree on. — Stephen Hawking

Since Einstein developed his theory of relativity, and Rutherford and Bohr revolutionised physics, our picture of the world has radically changed. — A. N. Wilson

String theory?[pause] It closed the conceptual gulp between relativity and quantum mechanics. It postulates that subatomic particles are not points, but strings, about one planck length long. The rate at which strings vibrate can generate the properties of all known particles. Huh? How did I know that? — Willie Garson

The action of the child inventing a new game with his playmates; Einstein formulating a theory of relativity; the housewife devising a new sauce for the meat, a young author writing his first novel; all of these are in terms of definition, Creative, and there is no attempt to set them in some order of more or less Creative. — Carl Rogers

Belief, like fear or love, is a force to be understood as we understand the theory of relativity and principals of uncertainty. Phenomena that determine the course of our lives. Yesterday, my life was headed in one direction. Today, it is headed in another. Yesterday, I believe I would never have done what I did today. These forces that often remake time and space, that can shape and alter who we
imagine ourselves to be, begin long before we are born and continue after we perish. Our lives and our choices, like quantum trajectories, are understood moment to moment. That each point of intersection, each encounter, suggest a new potential direction. Proposition, I have fallen in love with Luisa Rey. Is this possible? I just met her and yet, I feel like something important has happened to me. — David Mitchell

The ancient intuition that all matter, all "reality," is energy, that all phenomena, including time and space, are mere crystallizations of mind, is an idea with which few physicists have quarreled since the theory of relativity first called into question the separate identities of energy and matter. Today most scientists would agree with the ancient Hindus that nothing exists or is destroyed, things merely change shape or form; that matter is insubstantial in origin, a temporary aggregate of he pervasive energy that animates the electron. — Peter Matthiessen

In essence what relativity says is that space and time are not absolute but relative both to the observer and the thing being observed, and the faster one moves the more pronounced these effects will become. We can never accelerate ourselves to the speed of light, and the harder we try(the faster we go) the more distorted we become, relative to an outside observer. — Bill Bryson

If my theory of relativity is proven successful, Germany will claim me as a German and France will declare me a citizen of the world. Should my theory prove untrue, France will say that I am a German, and Germany will declare that I am a Jew. — Albert Einstein

The 4D style, or cosmic comics and relativistic humor, is based on Einstein's theory of relativity which I came up with 20 years ago. 4D works use the idea of the fourth dimension, time, playing on such surrealistic and amazing subjects as motion relativity, space curvature and time dilation. — Javad Alizadeh

I have read various articles on the fourth dimension, the relativity theory of Einstein, and other psychological speculation on the constitution of the universe; and after reading them I feel as Senator Brandegee felt after a celebrated dinner in Washington. "I feel," he said, "as if I had been wandering with Alice in Wonderland and had tea with the Mad Hatter." — Charles Lane Poor

I think, you know, the thing everybody really wants to know anyway is not what the theory of relativity is, but I think what we all really want to know anyways, is whether we're loved or not. — Rich Mullins

The special theory of relativity owes its origins to Maxwell's equations of the electromagnetic field. — Albert Einstein

My opinion about Miller's experiments is the following ... Should the positive result be confirmed, then the special theory of relativity and with it the general theory of relativity, in its current form, would be invalid. Experimentum summus judex. Only the equivalence of inertia and gravitation would remain, however, they would have to lead to a significantly different theory. — Albert Einstein

In the one real, time-drenched universe, everything has a particular history precisely because it is finite, and not part of an infinite array. Moreover, the cosmological use of the infinite serves to mask the failure of a physical theory taken beyond the boundaries of its proper domain of application. The most notable instance is the inference in contemporary cosmology of an infinite initial singularity from the field equations of general relativity. Finally, the admission of the mathematical infinite into natural science effaces the difference, which we emphasize, between nature and mathematics. Nature works in time, with which mathematics has trouble. Mathematics offers, among other things, the infinite, which nature abhors. — Lee Smolin

Every reflection today, whether nihilist or positivist, gives birth, sometimes without knowing it, to
standards that science itself confirms. The quantum theory, relativity, the uncertainty of interrelationships,
define a world that has no definable reality except on the scale of average
greatness, which is our own. The ideologies which guide our world were born in the time of absolute
scientific discoveries. Our real knowledge, on the other hand, only justifies a system of thought based on
relative discoveries. "Intelligence," says Lazare Bickel, "is our faculty for not developing what we think
to the very end, so that we can still believe in reality." Approximative thought is the only creator of
reality. — Albert Camus

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. — Max Planck

The chemist Peter Atkins correctly observed, "Natural selection was a revolution and a stepping-stone to fame; so was relativity, and so was quantum theory. The sheer thrill of discovery is the spur to greater effort. All young scientists aspire to revolution." The same can't be said for theologians (Martin Luther is a rare exception), who either bear their heresies in silence or aspire only to trivial reinterpretations of church doctrine. — Jerry A. Coyne

I count Maxwell and Einstein, Eddington and Dirac, among "real" mathematicians. The great modern achievements of applied mathematics have been in relativity and quantum mechanics, and these subjects are at present at any rate, almost as "useless" as the theory of numbers. — G.H. Hardy

Combining quantum entanglement with wormholes yields mind boggling results about black holes. But I don't trust them until we have a theory of everything which can combine quantum effects with general relativity. i.e. we need to have a full blown string theory resolve this sticky question. — Michio Kaku

Human rights are an aspect of natural law, a consequence of the way the universe works, as solid and as real as photons or the concept of pi. The idea of self- ownership is the equivalent of Pythagoras' theorem, of evolution by natural selection, of general relativity, and of quantum theory. Before humankind discovered any of these, it suffered, to varying degrees, in misery and ignorance. — L. Neil Smith

Some years ago I read a book that brought Einstein's theory of relativity down to an eighth grade level. This convinced me that any subject can be made easy. In other words, always beware of anyone who tells you a topic is above you or better left to experts. This person may, for some reason, be trying to shut you out. You CAN understand almost anything. — Richard J. Maybury

Should a priest reject relativity because it contains no authoritative exposition on the doctrine of the Trinity? Once you realize that the Bible does not purport to be a textbook of science, the old controversy between religion and science vanishes ... The doctrine of the Trinity is much more abstruse than anything in relativity or quantum mechanics; but, being necessary for salvation, the doctrine is stated in the Bible. If the theory of relativity had also been necessary for salvation, it would have been revealed to Saint Paul or to Moses. — Georges Lemaitre

The star S0-2 orbits around Sgr A* every 16 years and will go through its closest approach in 2018. That's an opportunity to test Einstein's General Relativity theory through very precise measurements of this star's short period orbit. — Andrea M. Ghez

The Great Pyramid of Giza was designed in agreement with the Theory of General Relativity. — Ibrahim Ibrahim

His new idea was published that month in what became yet another seminal Einstein paper, "Cosmological Considerations in the General Theory of Relativity."9 On the surface, it did indeed seem to be based on a crazy notion: space has no borders because gravity bends it back on itself. Einstein — Walter Isaacson

I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art. This is best seen in the theoretical aspects of Physical Science. The mathematical theorist builds up on certain assumptions and according to well understood logical rules, step by step, a stately edifice, while his imaginative power brings out clearly the hidden relations between its parts. A well constructed theory is in some respects undoubtedly an artistic production. A fine example is the famous Kinetic Theory of Maxwell ... The theory of relativity by Einstein, quite apart from any question of its validity, cannot but be regarded as a magnificent work of art. — Ernest Rutherford

The rotating armatures of every generator and motor in this age of electricity are steadily proclaiming the truth of the relativity theory to all who have ears to hear. — Leigh Page

The difficulty involved in the proper and adequate means of describing changes in continuous deformable bodies is the method of differential equations ... They express mathematically the physical concept of contiguous action.
Einstein's Theory of Relativity — Max Born

Whether it is a falling man or an orbiting satellite, the effect of inertia is to create an apparent upward force that depends on the mass of the object. It is the same force we feel when riding in a car that goes around a tight curve. This inertial effect is equal and opposite to gravity and therefore cancels the pull of gravity. In physicist language, the "gravitational mass" and "inertial mass" are equal. This is not a tautology, as Ambrose Bierce thought, but a recognition that the pull of gravity is proportional to the inertia of the object being pulled. Einstein called this the "Principle of Equivalence", and it became the basis for his new theory of gravity that he called the general theory of relativity. — Rodney A. Brooks

When we encounter unexpected obstacles in finding out something which we wish to know, there are two possible courses to take. It may be that the right course is to treat the obstacle as a spur to further efforts; but there is a second possibility - that we have been trying to find something which does not exist. You will remember that that was how the relativity theory accounted for the apparent concealment of our velocity through the aether. — Arthur Stanley Eddington

By far the most important consequence of the conceptual revolution brought about in physics by relativity and quantum theory lies not in such details as that meter sticks shorten when they move or that simultaneous position and momentum have no meaning, but in the insight that we had not been using our minds properly and that it is important to find out how to do so. — Percy Williams Bridgman

The revolution which began with the creation of quantum theory and relativity theory can only be finished with their unification into a single theory that can give us a single, comprehensive picture of nature. — Lee Smolin

No one must think that Newton's great creation can be overthrown in any real sense by this [Theory of Relativity] or by any other theory. His clear and wide ideas will for ever retain their significance as the foundation on which our modern conceptions of physics have been built. — Albert Einstein

However we select from nature a complex [of phenomena] using the criterion of simplicity, in no case will its theoretical treatment turn out to be forever appropriate (sufficient) ... I do not doubt that the day will come when [general relativity], too, will have to yield to another one, for reasons which at present we do not yet surmise. I believe that this process of deepening theory has no limits. — Albert Einstein

It is worth noting that a wrong folkoric definition of an Inertial Frame in the Popular Science literature (even in text books) reads that 'it is a frame in uniform motion'. We know very well by now that the idea of motion requires a frame of reference, so that such a definition of an Inertial Frame has no meaning whatsoever, confusing the reader because it tacitly reaffirms the idea of absolute motion
when the goal of every didactic exposition of Relativity Theory should be precisely the opposite. — Felix Alba-Juez

The Theory of Relativity makes nobody angry because it doesn't contradict any of our cherished beliefs. Most people don't care an iota whether space and time are absolute or relative. If you think it is possible to bend space and time, well be my guest. ...In contrast, Darwin has deprived us of our souls. If you really understand the Theory of Evolution, you understand that there is no soul. This is a terrifying thought, not only to devote Christians and Muslims, but also to many secular people who don't hold any clear religious dogma, but nevertheless, want to believe that each human possess an eternal, individual essence that remains unchanged throughout life and can survive even death intact. — Yuval Noah Harari

When I was doing Professor Albert Einstein's bust he had many a jibe at the Nazi professors, one hundred of whom had condemned his theory of relativity in a book. 'Were I wrong,' he said, 'one professor would have been enough. — Jacob Epstein

The difference between Lorentz's Transformation in Lorentz's theory and Lorentz's Transformation in Einstein's Special Relativity is not mathematical but ontological and epistemological and, being so, it was to be expected the emergence of historians, scientists, and philosophers that, not having understood in depth the philosophical content and transcendence of the theory, would minimize Einstein's contribution. — Felix Alba-Juez

Fractals, the theory of relativity, the genome: these are magnificently beautiful constructs. — Adam Savage

Einstein was arguing against quantum theory just as irrationally as his opponents had argued against relativity theory. Einstein remained adamant (he remained adamant to the end of his life where quantum theory was concerned). — Richard Rhodes

When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter. — Albert Einstein

One day you have Einstein, puzzling over the theory of relativity, the next you've got the Manhattan Project and a big hole in the ground. — Justin Cronin

I sometimes ask myself how it came about that I was the one to develop the theory of relativity. The reason, I think, is that a normal adult never stops to think about problems of space and time. These are things which he has thought about as a child. Bu t my intellectual development was retarded,as a result of which I began to wonder about space and time only when I had already grown up. — Albert Einstein

No one has yet discovered any warlike purpose to be served by the theory of numbers or relativity, and it seems unlikely that anyone will do so for many years. — G.H. Hardy

General theory of relativity and quantum mechanics. They are the great intellectual achievements of the first half of this century. — Stephen Hawking

Why should anyone raise an eyebrow because a latter-day Einstein's wife expects her husband to put aside that lifeless theory of relativity and help her with the work that is supposed to be the essence of life itself: diaper the baby and don't forge to rinse the soiled diaper in the toilet paper before putting it in the diaper pail, and then wax the kitchen floor. — Betty Friedan

It is almost impossible to have a baseless snobbish opinion of the General Theory of Relativity. — Michael Moorcock

Relativity theory forced the abandonment, in principle, of absolute space and absolute time. — Marshall McLuhan

The theory of relativity doesn't amount to a hill of beans when there's a bonfire in your shorts. — Lois Greiman

Einstein, like myself, found Bern pleasant but boring. And so I wonder: If the Swiss were more interesting, might he never have daydreamed as much as he did? Might he never have developed the Special Theory of Relativity? In other words, is there something to be said for boredom? — Eric Weiner

More philosophically-minded critics regarded Einstein's argument for relativity as little more than a logical bait-and-switch ploy: [T]he supposition of most expounders of the Special Theory, that Einstein has proved the relativity of simultaneity in general - or that his 'simultaneity' is something more than a logical artefact - must manifestly be given up. — Arthur Oncken Lovejoy

A falsifiable theory is one that makes a specific prediction about what results are supposed to occur under a set of experimental conditions, so that the theory might be falsified by performing the experiment and comparing predicted to actual results. A theory or explanation that cannot be falsified falls outside the domain of science. For example, Freudian psychoanalysis, which does not make specific experimental predictions, is able to revise its theory to match any observations, in order to avoid rejecting the theory altogether. By this reckoning, Freudianism is a pseudoscience, a theory that purports to be scientific but is in fact immune to falsification. In contrast, for example, Einstein's theory of relativity made predictions (like the bending of starlight around the sun) that were novel and specific, and provided opportunities to disprove the theory by direct experimental observation.
[The folly of scientism] — Austin L. Hughes

The media thinks that only the cutting edge of science, the very latest controversies, are worth reporting on. How often do you see headlines like 'General Relativity still governing planetary orbits' or 'Phlogiston theory remains false'? By the time anything is solid science, it is no longer a breaking headline. — Eliezer Yudkowsky

I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics. — Max Born

The current leading candidates for dark matter are particles predicted to exist from supersymmetric theories, extensions of current particle physics that include a new symmetry of Nature. The reader may recognize the "super" in supersymmetry from superstring theory, a candidate theory for unifying general relativity and quantum mechanics. As of the winter of 2014, no evidence for supersymmetry had been found, despite decades of intense search and the enthusiastic support of many physicists. At this point, it is unclear and somewhat doubtful that supersymmetry is realized in Nature. — Marcelo Gleiser

More careful reflection teaches us, however, that the special theory of relativity does not compel us to deny ether...To deny the ether is ultimately to assume that empty space has no physical qualities whatever. — Albert Einstein

I believe that the Big-Bang Theory and the Evolution Theory, as well as Einstein's Special Relativity Theory which does not allow for the existence of faster-than-light (superluminal) phenomena, all have flaws in them and must be replaced by new theories that can give Mankind a more concise view of our Universe. But the fact is exceptional discoveries and theories that challenge official science have been ignored by the Establishment for decades. — Takaaki Musha

I'm not sure why I enjoy debunking. Part of it surely is amusement over the follies of true believers, and [it is] partly because attacking bogus science is a painless way to learn good science. You have to know something about relativity theory, for example, to know where opponents of Einstein go wrong ... Another reason for debunking is that bad science contributes to the steady dumbing down of our nation. Crude beliefs get transmitted to political leaders and the result is considerable damage to society. — Martin Gardner

The importance of C.F. Gauss for the development of modern physical theory and especially for the mathematical fundament of the theory of relativity is overwhelming indeed; also his achievement of the system of absolute measurement in the field of electromagnetism. In my opinion it is impossible to achieve a coherent objective picture of the world on the basis of concepts which are taken more or less from inner psychological experience. — Albert Einstein

Despite the earnest belief of most of his fans, Einstein did not win his Nobel Prize for the theory of relativity, special or general. He won for explaining a strange effect in quantum mechanics, the photoelectric effect. His solution provided the first real evidence that quantum mechanics wasn't a crude stopgap for justifying anomalous experiments, but actually corresponds to reality. And the fact that Einstein came up with it is ironic for two reasons. One, as he got older and crustier, Einstein came to distrust quantum mechanics. Its statistical and deeply probabilistic nature sounded too much like gambling to him, and it prompted him to object that "God does not play dice with the universe." He was wrong, and it's too bad that most people have never heard the rejoinder by Niels Bohr: "Einstein! Stop telling God what to do. — Sam Kean

Doesn't the theory of relativity concern literature too? In our world there is no longer any room for the privileged observer, as there is none for the observer of the universe - we are all within. — Nina Berberova

The theory of relativity worked out by Mr. Einstein, which is in the domain of natural science, I believe can also be applied to the political field. Both democracy and human rights are relative concepts - and not absolute and general. — Jiang Zemin

What makes the theory of relativity so acceptable to physicists in spite of its going against the principle of simplicity is its great mathematical beauty. This is a quality which cannot be defined, any more than beauty in art can be defined, but which people who study mathematics usually have no difficulty in appreciating. — Paul Dirac

Early-twentieth-century abstraction is art's version of Einstein's Theory of Relativity. It's the idea that changed everything everywhere: quickly, decisively, for good. — Jerry Saltz

Einstein, my upset stomach hates your theory [of General Relativity] - it almost hates you yourself! How am I to' provide for my students? What am I to answer to the philosophers?!! — Paul Ehrenfest

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

I believe my theory of relativity to be true. But it will only be proved for certain in 1981, when I am dead. — Albert Einstein

Asked in 1919 whether it was true that only three people in the world understood the theory of general relativity, [Eddington] allegedly replied: 'Who's the third? — Arthur Stanley Eddington

During the 1919 solar eclipse, people go out to measure the positions of the stars and they find exactly what Einstein predicted. Einstein gets a telegram saying this, and somebody asked him, Professor Einstein, what would you have said if the observations didn't agree with what your prediction of general relativity said should be happening? And Einstein said, "I'd be sorry for the dear lord; the theory is correct." What he meant by that is the math is just so elegant, so beautiful, so powerful, that almost seemingly it can't possibly be wrong. — Rivka Galchen

Well, it has done terrifying things. Religious ideas are inflammatory in a way that I find difficult to understand. There are very few wars over the theory of relativity. Very few heated arguments, for that matter. Whereas, in Northern Ireland, they are killing one another over religion. — Quentin Crisp

The theory of relativity and quantum mechanics argue that you can twist time and space, that something can appear out of nothing, and that a cat can be both alive and dead at the same time. This makes a mockery of our common sense, yet nobody seeks to protect innocent schoolchildren from these scandalous ideas. Why? The theory of relativity makes nobody angry, because it doesn't contradict any of our cherished beliefs. Most people don't care an iota whether space and time are absolute or relative. If you think it is possible to bend space and time, well, be my guest. Go ahead and bend them. What do I care? In contrast, Darwin has deprived us of our souls — Yuval Noah Harari

In my personal experience I have hardly come to know the wretchedness of mankind better than as a result of the general theory of relativity and everything connected to it. But it doesn't bother me. — Albert Einstein

Yet, emotionally I could not bring myself to accept either his presence, or his reality. My problem was not a religious problem. God could certainly create as many variations of intelligent humans as he wanted. Presumably God put humans here on this earth, and all non-humans on some other far-away planet orbiting some other far-away star. My problem was a scientific problem. For the Tall White guard to be standing there in the hot sun, for real, would mean that everything I had been taught about Einstein and the Theory of Relativity was simply incorrect. — Charles James Hall

Now, from special relativity we know that energy and mass are two sides of the same coin: Greater energy means greater mass, and vice versa. Thus, according to string theory, the mass of an elementary particle is determined by the energy of the vibrational pattern of its internal string. Heavier particles have internal strings that vibrate more energetically, while lighter particles have internal strings that vibrate less energetically. — Brian Greene

The last I knew you were going to a party. just a few friends at the McEvoys' you told me. The science club, you told me. What happened? You got into a fight about the theory of relativity? Did creationists crash the party and start a rumble? — Tami Hoag

Naively, special relativity would therefore tell us that those particles should be able to travel forwards and backwards in time as well. But so far as we know, neither particles nor anything else we are aware of can actually travel backwards in time. What happens instead is that oppositely charged antiparticles replace the reverse-time-traveling particles. Antiparticles reproduce the effects the reverse-time-traveling particles would have so that even without them, quantum field theory's predictions are compatible with special relativity. — Lisa Randall

As Sommerfeld said in his famous text "Spectral Lines and Atomic Constitution," on which a generation of physicists learned the subject, "In the fine structure constant e is the representative of the electron theory, h the appropriate representative of the quantum theory, c comes from relativity and characterizes it in contrast to classical theory. — Emilio Segre

Relativity was a highly technical new theory that gave new meanings to familiar concepts and even to the nature of the theory itself. The general public looked upon relativity as indicative of the seemingly incomprehensible modern era, educated scientists despaired of ever understanding what Einstein had done, and political ideologues used the new theory to exploit public fears and anxieties-all of which opened a rift between science and the broader culture that continues to expand today. — David C. Cassidy

Never be ashamed of madness, instead be ashamed of people that are ashamed of madness. Without a little bit of insanity, we would have never had the Theory of Relativity, electricity, airplanes, cars or your beloved iPhone. Madness got you that. — Shannon L. Alder

While Einstein's theory of relativity may one day put Earth on the intergalactic map, it will always run a distant second to the Lord's Prayer, whose harnessing of energies in their proper, life-giving direction surpasses even the discovery of fire.[2] — Brian Zahnd

One looks forward to the day when the General Theory of Relativity and the Principia will outsell the Kama Sutra in back-street bookshops. — J.G. Ballard

Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things. — Brian Greene

I get paid to do what I love. If you understand physics, the foundation of the atomic theory and relativity, you understand how the future is going to unfold. You understand what things are not possible. You understand why things work. I get paid to do what I love the most, and that is to work on the Unified Field Theory and to see the future. — Michio Kaku

In Einstein's theory of relativity the observer is a man who sets out in quest of truth armed with a measuring-rod. In quantum theory he sets out with a sieve. — Arthur Eddington

It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system. — Talcott Parsons

Upon hearing via Littlewood an exposition on the theory of relativity: To think I have spent my life on absolute muck. — Bertrand Russell

Since the mathematicians have grabbed hold of the theory of relativity, I myself no longer understand it. — Walter Isaacson

Now Einstein was a very clever man, with us all his philosophies he shared, He gave us the theory of relativity, which is E equals M C squared. — Richard Digance

Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out. — Stephen Hawking

The facts of physics do not oblige us to accept one philosophy rather than the other...the laws of physics in any one reference frame account for all physical phenomena, including the observations of moving observers. And it is often simplest to work in a single frame, rather than to hurry after each moving object in turn...You can pretend that whatever inertial frame you have chosen is the ether of the 19th century physicists, and in that frame you can confidently apply the ideas of the FitzGerald contraction....It is a great pity that students don't understand this. Very often they are led to believe that Einstein somehow swept away all that went before. This is not true. Much of what went before survived the theory of relativity, with the added freedom that you can choose any inertial frame of reference in which to apply all those ideas. — John S. Bell

Time is described only in terms of change in the network of relationships that describes space. This means that it is absurd in general relativity to speak of a universe in which nothing happens. Time is nothing but a measure of change-it has no other meaning. Neither space nor time has any existence outside the system of evolving relationships that comprises the universe. Physicists refer to this feature of general relativity as background independence. By this we mean that there is no fixed background, or stage, that remains fixed for all time. In contrast, a theory such as Newtonian mechanics or electromagmetism is background dependent because it assumes that there exists a fixed, unchanging background that provides the ultimate answer to all questions about where and when. — Lee Smolin

If one could see an infinite distance, they would observe the back of their head. That is Einstein's theory in a nut-shell. — R. Alan Woods

A successful unification of quantum theory and relativity would necessarily be a theory of the universe as a whole. It would tell us, as Aristotle and Newton did before, what space and time are, what the cosmos is, what things are made of, and what kind of laws those things obey. Such a theory will bring about a radical shift - a revolution - in our understanding of what nature is. It must also have wide repercussions, and will likely bring about, or contribute to, a shift in our understanding of ourselves and our relationship to the rest of the universe. — Lee Smolin

One of the most exciting things about dark energy is that it seems to live at the very nexus of two of our most successful theories of physics: quantum mechanics, which explains the physics of the small, and Einstein's Theory of General Relativity, which explains the physics of the large, including gravity. — Adam Riess
