[John Wheeler] rejuvenated general relativity; he made it an experimental subject and took it away from the mathematicians
Quantum field theory, which was born just fifty years ago from the marriage of quantum mechanics with relativity, is a beautiful but not very robust child.
How are you going to teach virtue if you teach the relativity of all ethical ideas? Virtue, if it implies anything at all, implies an ethical absolute. A person whose idea of what is proper varies from day to day can be admired for his broadmindedness, but not for his virtue.
No, I don't understand my husband's theory of relativity, but I know my husband and I know he can be trusted.
In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.
There are periods in life when you get caught up in the whole field of relativity and lose your moorings with the absolute.
To the philosophers of India, however, Relativity is no new discovery, just as the concept of light years is no matter for astonishment to people used to thinking of time in millions of kalpas, (A kalpa is about 4,320,000 years). The fact that the wise men of India have not been concerned with technological applications of this knowledge arises from the circumstance that technology is but one of innumerable ways of applying it.
Since the mathematicians have invaded the theory of relativity I do not understand it myself any more.
Relativity must replace absolutism in the realm of morals as well as in the spheres of physics and biology.
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.
When you sit with a nice girl for two hours, it seems like two minutes; when you sit on a hot stove for two minutes, it seems like two hours. That's relativity.
Have you ever heard of the theory of relativity?" Artemis blinked. "Is this a joke? I have traveled through time, Doctor. I think I know a little something about relativity.
Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity.
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.
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.
If you use language that divides people and makes people who agree with you really stoked and people who disagree with you disengaged then you're preaching to a choir, and you've lost any kind of relativity across the spectrum. So it's important to be subtle and understand that there's a lot more you can learn.
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.
When I meet God, I am going to ask him two questions: Why relativity ? And why turbulence ? I really believe he will have an answer for the first.
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."
The supposed astronomical proofs of the theory [of relativity], as cited and claimed by Einstein, do not exist. He is a confusionist. The Einstein theory is a fallacy. The theory that ether does not exist, and that gravity is not a force but a property of space can only be described as a crazy vagary, a disgrace to our age.
A first grader should understand that her or his culture isn't a rational invention; that there are thousands of other cultures and they all work pretty well; that all cultures function on faith rather than truth; that there are lots of alternatives to our own society...Cultural relativity is defensible, attractive. It's a source of hope. It means we don't have to continue this way if we don't like it.
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.
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
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.
Let me tell you about Australia. It's really, really, really, far from wherever you live on Earth. You fly and you fly and you fly. Then relativity takes over and you get younger and younger. And when you land, you're a gleam in your father's eye.
