Thanks to my fortunate idea of introducing the relativity principle into physics, you (and others) now enormously overrate my scientific abilities, to the point where this makes me quite uncomfortable.
It is almost impossible to have a baseless snobbish opinion of the General Theory of Relativity.
I don't believe in bad. I believe in relativity. The only way we can know what we call good is if there's also something we call bad.
At some point we must realize that actively defending against radical Islamic teachings is not a matter of cultural relativity. It is a matter of universally recognized human rights.
Those instrumental goods which should serve to maintain the life and health of all human beings should be produced by the least possible labour of all.
God is subtle but he is not malicious.
The modern physicist is a quantum theorist on Monday, Wednesday, and Friday, and a student of gravitational relativity on Tuesday, Thursday, and Saturday. On Sunday, he is praying... that someone will find the reconciliation between the two views.
Some scientist needs to explain to spectators Einstein's relativity theory. Before his explanation, he says: 'I have to suffer a lot explaining something I don't understand myself.' This relates to my game: I didn't understand anything!
I'm a great believer in relativity when making movies. Relativity, in my mind, meaning "Light to dark, big to small, good to bad." You visually embrace these things to enhance transitions and instantly paint environments and moods.
We went to the moon using just Newton's laws of motion and gravity. Newtonian dynamics we call it. So then we find out, "Well, this works because there's certain regimes we've never tested it in." Had we done so, we would show that it didn't work: For example, at very high speeds, very high gravity, Newton's laws fail. They just fail. You need Einstein's laws of motion and gravity. Those would be his special theory of relativity and general theory of relativity. Now you invoke those and it works.
For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.
Formerly, people thought that if matter disappeared from the universe, space and time would remain. Relativity declares that space and time would disappear with matter.
It is ironic that Einsteins most creative work, the general theory of relativity, should boil down to conceptualizing space as a medium when his original premise [in special relativity] was that no such medium existed[..].
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.
The prime lesson the social sciences can learn from the natural sciences is just this: that it is necessary to press on to find the positive conditions under which desired events take place, and that these can be just as scientifically investigated as can instances of negative correlation. This problem is beyond relativity.
Fractals, the theory of relativity, the genome: these are magnificently beautiful constructs.
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.
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.
When the solution is simple, God is answering.
Common sense is nothing more than a deposit of prejudices laid down by the mind before you reach eighteen.
The best everyday example of relativity, the finest symptom of human intelligence, is humor. (...) Design without humor is not human. The word 'beautiful' does not mean anything. Only coherence counts. An object, design or not, is primarily an object that meets the parameters of human intelligence, which reconciles opposites. The lack of humor is the definition of vulgarity.
In my relativity theory I set up a clock at every point in space, but in reality I find it difficult to provide even one clock in my room.
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.
Since Einstein developed his theory of relativity, and Rutherford and Bohr revolutionised physics, our picture of the world has radically changed.
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.
What lead me more or less directly to the special theory of relativity was the conviction that the electromotive force acting on a body in motion in a magnetic field was nothing else but an electric field.
In the context of general relativity, space almost is a substance. It can bend and twist and stretch, and probably the best way to think about space is to just kind of imagine a big piece of rubber that you can pull and twist and bend.
Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.
Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists.
Small is the number of them that see with their own eyes and feel with their own hearts.
You teach me baseball and I'll teach you relativity...No we must not. You will learn about relativity faster than I learn baseball.
One cannot help but be in awe when [one] contemplates the mysteries of eternity, of life, of the marvelous structure of reality.
The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity.
I like relativity and quantum theories because I don't understand them and they make me feel as if space shifted about like a swan that can't settle, refusing to sit still and be measured; and as if the atom were an impulsive thing always changing its mind.
Evidence in support of general relativity came quickly. Astronomers had long known that Mercury’s orbital motion around the sun deviated slightly from what Newton’s mathematics predicted. In 1915, Einstein used his new equations to recalculate Mercury’s trajectory and was able to explain the discrepancy, a realization he later described to his colleague Adrian Fokker as so thrilling that for some hours it gave him heart palpitations.
I am enough of an artist to draw freely upon my imagination.
Whoever undertakes to set himself up as a judge of Truth and Knowledge is shipwrecked by the laughter of the gods.
[Mystery] is the fundamental emotion that stands at the cradle of true art and true science.
At present every coachman and every waiter argues about whether or not the relativity theory is correct.
There is no dualism in the world of light. The conventions of relativity say that time slows down as one approaches the speed of light, but if one tries to imagine the point of view of a thing made of light, one must realize that what is never mentioned is that if one moves at the speed of light there is no time whatsoever... One exists in eternity, one has become eternal... One is then apart from the moving image; one exists in the completion of eternity.
Only a life lived for others is a life worthwhile.
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.
Our task must be to free ourselves by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty.
It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing - a somewhat unfamiliar conception for the average mind. Furthermore, the equation E = mc², in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa.
If I were not a physicist, I would probably be a musician. I often think in music. I live my daydreams in music. I see my life in terms of music.
The vanity of existence is revealed in the whole form existence assumes: in the infiniteness of time and space contrasted with the finiteness of the individual in both; in the fleeting present as the sole form in which actuality exists; in the contingency and relativity of all things; in continual becoming without being; in continual desire without satisfaction; in the continual frustration of striving of which life consists. . . Time is that by virtue of which everything becomes nothingness in our hands and loses all real value.
Common sense is the collection of prejudices acquired by age eighteen.
Gravitational waves will bring us exquisitely accurate maps of black holes - maps of their space-time. Those maps will make it crystal clear whether or not what were dealing with are black holes as described by general relativity.
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.
