Top 1200 Theories Of Relativity Quotes & Sayings - Page 2

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

Relativity applies to physics, not ethics.

We lay down a fundamental principle of generalization by abstraction: The existence of analogies between central features of various theories implies the existence of a general theory which underlies the particular theories and unifies them with respect to those central features.

Theories of history used to be supernatural: the divine ruled time; the hand of God, a special providence, lay behind the fall of each sparrow. If the present differed from the past, it was usually worse: supernatural theories of history tend to involve decline, a fall from grace, the loss of God's favor, corruption.

Tell me it's never been done. Because the only real laws in this world-the only things we really know-are the two postulates of relativity, the three laws of Newton, the four laws of thermodynamics, and Maxwell's equation-no, scratch that, the only things we really know are Maxwell's equations, the three laws of Newton, the two postulates of relativity, and the periodic table. That's all we know that's true. All the rest are man's laws

Evolution has long been badly taught. In particular, students - and even professional biologists - acquire theories of evolution without any deep understanding of what problem these theories attempt to solve. They learn but little of the evolution of evolutionary theory.

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.

Before I married, I had three theories about raising children and no children. Now, I have three children and no theories.

It is ... a sign of the times-though our brothers of physics and chemistry may smile to hear me say so-that biology is now a science in which theories can be devised: theories which lead to predictions and predictions which sometimes turn out to be correct. These facts confirm me in a belief I hold most passionately-that biology is the heir of all the sciences.

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

Progress is achieved by exchanging our theories for new ones which go further than the old, until we find one based on a larger number of facts. ... Theories are only hypotheses, verified by more or less numerous facts. Those verified by the most facts are the best, but even then they are never final, never to be absolutely believed.

One of the greatest sources of problems in our society arises from people having loads of wrong theories in their heads - often theories that are critical of others - that they won't test by speaking to the relevant people about them. Instead, they talk behind people's backs, which leads to pervasive misinformation.

Human beings really think about relativity. That's part of what the brain does.

Newton's theory is not 'not right', it just does not cover all distances. Contrary to popular belief, theories in science are not proven wrong, they are just replaced by more complete and convenient theories. To sound provocative, even the geocentric theory was never "proven" wrong, it is just not as convenient as the heliocentric theory, since it requires endless epicycles.

The Church demonstrated the falsity and folly of Darwin's theories by showing that they contradicted the Mosaic account of creation, and now that the theories of Darwin having been fairly established, the Church says that the Mosaic account is true because it is in harmony with Darwin. Now, if it should turn out that Darwin was mistaken, what then?

People want to think of economics as a natural science, like physics, with the comforting reliability of simple-to-understand theories like F=MA. Unfortunately, it isn't. Economics is a social science, and the so-called theories are really social and moral constructs.

Since the mathematicians have invaded the theory of relativity I do not understand it myself any more.

I always found it satisfying that gravity was described by Einstein's geometric theory of general relativity.

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

The central Christian belief is that Christ's death has somehow put us right with God and given us a fresh start. Theories as to how it did this are another matter. A good many different theories have been held as to how it works; what all Christians are agreed on is that it does work.

The first step toward the management of disease was replacement of demon theories and humours theories by the germ theory. That very step, the beginning of hope, in itself dashed all hopes of magical solutions. It told workers that progress would be made stepwise, at great effort, and that a persistent, unremitting care would have to be paid to a discipline of cleanliness. So it is with software engineering today.

We cannot explain the phenomenon of gravitational lensing without general relativity, and this is where MOND spectacularly fails.

Even in relativity theory even though you can analyze space - time in terms of this four-dimensional geometrical structure one of the dimensions is different. And this shows up in the equations. It has a different sign - rather than plus it shows up as a negative minus. So even in relativity theory time is distinct from space in terms of the way in which these dimensions manifest themselves in the equations.

Art is very mysterious. I wonder if you can really do any damage to art. I think that when we're writing, something comes through or should come through, in spite of our theories. So theories are not really important.

Methodological naturalism gives advice to scientists about what they should include in their theories. There is a second type of methodological naturalism that gives advice to philosophers, which I call "methodological naturalismp." It says that the methods that philosophers should use in assessing philosophical theories are limited to the methods that scientists ought to use in assessing scientific theories.

Man is so intelligent that he feels impelled to invent theories to account for what happens in the world. Unfortunately, he is not quite intelligent enough, in most cases, to find correct explanations. So that when he acts on his theories, he behaves very often like a lunatic.

Yet the widespread planetary theories, advanced by Ptolemy and most other astronomers, although consistent with the numerical data, seemed likewise to present no small difficulty. For these theories were not adequate unless they also conceived certain equalizing circles, which made the planet appear to move at all times with uniform velocity neither on its deferent sphere nor about its own epicycle's center.

Theories without facts may be barren, but facts without theories are meaningless.

Generally the theories we believe we call facts, and the facts we disbelieve we call theories.

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

The menstruation taboo is ancient, and there are so many theories about it. For some, it is fear of blood, and for some, period blood is toxic. If you read the theories about menstruation, you might even laugh.

I noticed affixed to a laboratory door the following words: "Les théories passent. Le Grenouille reste. [The theories pass. The frog remains.] &mdashJean Rostand, Carnets d'un biologiste." There is a risk that in the less severe discipline of criticism the result may turn out to be different; the theories will remain but the frog may disappear.

Relativity teaches us the connection between the different descriptions of one and the same reality.

Theory is a dirty word in some managerial quarters. That is rather curious, because all of us, managers especially, can no more get along without theories than libraries can get along without catalogs and for the same reason: theories help us make sense of incoming information.

It is our hope, that men in proportion as they grow more enlightened, will learn to hold their theories and their creeds more loosely, and will none the less, nay, rather all the more be devoted to the supreme end of practical righteousness to which all theories and creeds must be kept subservient.

It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing...

To show the relativity of what's good taste and what's not is something I like to play with.

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

Relativity must replace absolutism in the realm of morals as well as in the spheres of physics and biology.

The field equations and the whole history of general relativity have been complicated.

History has got a lot to do with unique circumstances under certain particular cases and grand theories will always find counter cases. I don't think that people whose expertise lies in one thing should try to make grand theories about something (a) where it's very hard to get the evidence to prove that you're right and (b) where it's much too easy to make up stories that seem right.

[John Wheeler] rejuvenated general relativity; he made it an experimental subject and took it away from the mathematicians

I now want to tell three stories about advances in twentieth-century physics. A curious fact emerges in these tales: time and again physicists have been guided by their sense of beauty not only in developing new theories but even in judging the validity of physical theories once they are developed. Simplicity is part of what I mean by beauty, but it is a simplicity of ideas, not simplicity of a mechanical sort that can be measured by counting equations or symbols.

Facts quite often, I fear to confess, like lawyers, put me to sleep at noon. Not theories, however. Theories are invigorating and tonic. Give me an ounce of fact and I will produce you a ton of theory by tea this afternoon. That is, after all, my job.

Propose theories which can be criticized. Think about possible decisive falsifying experiments-crucial experiments. But do not give up your theories too easily-not, at any rate, before you have critically examined your criticism.

Theories by women about women have only recently begun to appear in print. Theories by men about women are abundant.

There are many examples of old, incorrect theories that stubbornly persisted, sustained only by the prestige of foolish but well-connected scientists... Many of these theories have been killed off only when some decisive experiment exposed their incorrectness... Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest.

I learned Einstein's theory of relativity when I was still in school. I simply got interested.

The rhythm of relations of color and size makes the absolute appear in the relativity of time and space.

The method of science depends on our attempts to describe the world with simple theories: theories that are complex may become untestable, even if they happen to be true. Science may be described as the art of systematic over-simplification-the art of discerning what we may with advantage omit.

In this business, if you don`t have the capacity to step back and have some sort of relativity about things, you're screwed.

In 1905 Albert discovered Relativity, in 1906 he invented Rock and Roll.

Relativity is a purely scientific matter and has nothing to do with religion.

A theory not only explains the world we see, it lets us imagine other worlds, and, even more significantly, lets us act to create those worlds. Developing everyday theories, like scientific theories, has allowed human beings to change the world.

Now to the term 'relativity theory.' I admit that it is unfortunate, and has given occasion to philosophical misunderstandings.

Facts do not speak for themselves. They speak for or against competing theories. Facts divorced from theories or visions are mere isolated curiosities.

For the theory-practice iteration to work, the scientist must be, as it were, mentally ambidextrous; fascinated equally on the one hand by possible meanings, theories, and tentative models to be induced from data and the practical reality of the real world, and on the other with the factual implications deducible from tentative theories, models and hypotheses.

Let's develop theories, patiently and honestly thinking them out, in order to promptly act against them – acting and justifying our actions with new theories that condemn them. Let's cut a path in life and then go immediately against that path. Let's adopt all the poses and gestures of something we aren't and don't even wish to be, and don't even wish to taken for being.

Managers are already voracious consumers of theory. Every time they make a decision or take action, it's based on some theory that leads them to believe that action will lead to the right result. The problem is, most managers aren't aware of the theories they're using, and they often use the wrong theories for the situation.

Biochemists and biologists who adhere blindly to the Darwinism theory search for results that will be in agreement with their theories and consequently orient their research in a given direction, whether it be in the field of ecology, ethology, sociology, demography (dynamics of populations), genetics (so-called evolutionary genetics), or paleontology. This intrusion of theories has unfortunate results: it deprives observations and experiments of their objectivity, makes them biased, and, moreover, creates false problems.
