Top 1200 Theory And Practice Quotes & Sayings - Page 3

I don't think about a theory of everything when I do my research. And even if we knew the ultimate underlying theory, how are you going to explain the fact that we're sitting here? Solving string theory won't tell us how humanity was born.

I practice a lot. I practice in the winter when it's cold in Connecticut - a lot. I practice in my bedroom on the carpet - a lot. For all the practice I do, I should be a better golfer than I am.

It is easy to obtain confirmations, or verifications, for nearly every theory-if we look for confirmations. Confirmations should count only if they are the result of risky predictions... A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice. Every genuine test of a theory is an attempt to falsify it, or refute it.

Atheism is a natural and inseparable part of Marxism, of the theory and practice of scientific socialism. Our program necessarily includes the propaganda of atheism.

Forms of government are forged mainly in the fire of practice, not in the vacuum of theory. They respond to national character and to national realities.

Indeed, this epistemological theory of the relation between theory and experiment differs sharply from the epistemological theory of naive falsificationism.

My point is that the alienation of theory and practice, intellectual and manual labor, is a real issue, but it's the outcome of social domination; it's sort of a mistake to blame it on the subjects of that domination.

How do you best move toward mastery? To put it simply, you practice diligently, but you practice primarily for the sake of the practice itself.

We come finally, however, to the relation of the ideal theory to real world, or "real" probability. If he is consistent a man of the mathematical school washes his hands of applications. To someone who wants them he would say that the ideal system runs parallel to the usual theory: "If this is what you want, try it: it is not my business to justify application of the system; that can only be done by philosophizing; I am a mathematician". In practice he is apt to say: "try this; if it works that will justify it".

Practice, practice, practice. Practice until you get a guitar welt on your chest...if it makes you feel good, don't stop until you see the blood from your fingers. Then you'll know you're on to something!

The standard theory may survive as a part of the ultimate theory, or it may turn out to be fundamentally wrong. In either case, it will have been an important way-station, and the next theory will have to be better.

In theory, and I think in practice, I am immune to the strain of Ebola that I was infected with. But there are five different strains of Ebola.

Has not the experience of two centuries shown that gradualism in theory is perpetuity in practice? Is there an instance, in the history of the world, where slaves have been educated for freedom by their task-masters?

When we meet a fact which contradicts a prevailing theory, we must accept the fact and abandon the theory, even when the theory is supported by great names and generally accepted.

The theory of chaos and theory of fractals are separate, but have very strong intersections. That is one part of chaos theory is geometrically expressed by fractal shapes.

As my colleague, the physical chemist Peter Atkins, puts it, we must be equally agnostic about the theory that there is a teapot in orbrit around the planet Pluto. We can't disprove it. But that doesn't mean the theory that there is a teapot is on level terms with the theory that there isn't.

I had two passions when I was a child. First was to learn about Einstein's theory and help to complete his dream of a unified theory of everything. That's my day job. I work in something called string theory. I'm one of the founders of the subject. We hope to complete Einstein's dream of a theory of everything.

There are two theories. There's one theory that Barack Obama wants to destroy the country and create a socialistic country. There is that theory, and I've read a lot. This isn't necessarily my theory. I personally think they're incompetent.

One important idea is that science is a means whereby learning is achieved, not by mere theoretical speculation on the one hand, nor by the undirected accumulation of practical facts on the other, but rather by a motivated iteration between theory and practice.

The theory of Zen is non-competition. But that is not really true at all. People who practice Zen are very competitive. They are competing against emptiness.

Every opportunity to practice is a gift to the developing reader. Practice, practice, practice, in every form and medium!

Always think about practice... theory is not the endpoint of work, it is the work along the way to work.

Theory is worth but little, unless it can explain its own phenomena, and it must effect this without contradicting itself; therefore, the facts are sometimes assimilated to the theory, rather than the theory to the facts.

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory.

Practice, practice, practice in speaking before an audience will tend to remove all fear of audiences, just as practice in swimming will lead to confidence and facility in the water. You must learn to speak by speaking.

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.

In the Cold War, a lot of Soviet actions could be explained as extensions of Czarist imperial ambitions, but that didn't stop us from studying Marxism in theory and Communism in practice to better understand that adversary.

I think it laughable, frankly, that the physics community comes up with a theory for everything. There isn't one theory for everything. There is not one explanation. We may eventually have several theories that can tie things together nicely but there is not a single theory of everything.

What makes knowledge automatic is what gets you to Carnegie Hall - practice, practice, practice.

Evolution ... is really two theories, the vague theory and the precise theory. The vague theory has been abundantly proved.... The precise theory has never been proved at all. However, like relativity, it is accepted on faith.... On getting down to actual details, difficulties begin.

If I can't practice, I can't practice. It is as simple as that. I ain't about that at all. It's easy to sum it up if you're just talking about practice. We're sitting here, and I'm supposed to be the franchise player, and we're talking about practice. I mean listen, we're sitting here talking about practice, not a game, not a game, not a game, but we're talking about practice. Not the game that I go out there and die for and play every game like it's my last, but we're talking about practice man. How silly is that?

The theory of natural selection is the centerpiece of The Origin of Species and of evolutionary theory. It is this theory that accounts for the adaptations of organisms, those innumerable features that so wonderfully equip them for survival and reproduction; it is this theory that accounts for the divergence of species from common ancestors and thus for the endless diversity of life. Natural selection is a simple concept, but it is perhaps the most important idea in biology.
