A Quote by G. H. Hardy

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
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.
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.
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.
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.
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.
I heard that in relativity theory, space and time are the same thing. Einstein discovered this when he kept showing up three miles late for his meetings.
The indispensability argument says (roughly) that if you have ample reason to accept an empirical scientific theory that makes indispensable use of mathematics, and that theory entails that numbers exist, then you have ample reason to accept that numbers exist. The argument affirms the antecedent of this conditional, and concludes that you have ample reason to believe that numbers exist. What is striking about this argument is that it seems to show that the empirical reasons that suffice for accepting a scientific theory also suffice for accepting a metaphysical claim.
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.
For thirty years I have leaned toward the theory of Reincarnation. It seems a most reasonable philosophy and explains many things. No, I have no desire to know what, or who I was once; or what, or who, I shall be in the ages to come. This belief in immortality makes present living the more attractive. It gives you all the time there is. You will always be able to finish what you start. There is no fever or strain in such an outlook. We are here in life for one purpose: to get experience. We are all getting it, and we shall all use it somewhere.
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.
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.
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.
General relativity is in the old Newtonian framework where you predict what will happen, not the probability of what will happen. And putting together the probabilities of quantum mechanics with the certainty of general relativity, that's been the big challenge and that's why we have been excited about string theory, as it's one of the only approaches that can put it together.
For many years, I have lived uncomfortably with the belief that most planning and architectural design suffers for lack of real and basic purpose. The ultimate purpose, it seems to me, must be the improvement of mankind.
Since the mathematicians have invaded the theory of relativity I do not understand it myself any more.
A logical theory may be tested by its capacity for dealing with puzzles, and it is a wholesome plan, in thinking about logic, to stock the mind with as many puzzles as possible, since these serve much the same purpose as is served by experiments in physical science.
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.
