Top 1200 Quantum Theory Quotes & Sayings - Page 4

No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.

It is not enough for theory to describe and analyze, it must itself be an event in the universe it describes. In order to do this theory must partake of and become the acceleration of this logic. It must tear itself from all referents and take pride only in the future. Theory must operate on time at the cost of a deliberate distortion of present reality.

Some claim evolution is just a theory. As if it were merely an opinion. The theory of evolution, like the theory of gravity, is a scientific fact. Evolution really happened. Accepting our kinship with all life on Earth is not only solid science. In my view, it’s also a soaring spiritual experience.

The theory of mechanism design can be thought of as the 'engineering' side of economic theory.

If what we regard as real depends on our theory, how can we make reality the basis of our philosophy? But we cannot distinguish what is real about the universe without a theory. It makes no sense to ask if it corresponds to reality, because we do not know what reality is independent of a theory.

Well, it [evolution] is a theory, it is a scientific theory only, and it has in recent years been challenged in the world of science and is not yet believed in the scientific community to be as infallible as it once was believed. But if it was going to be taught in the schools, then I think that also the biblical theory of creation, which is not a theory but the biblical story of creation, should also be taught.

Theories are not rejected by cirsumstantial evidence: it takes a theory to beat a theory.

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.

Theory is the essence of facts. Without theory scientific knowledge would be only worthy of the madhouse.

Einstein's theory of General Relativity has a mathematical structure very similar to Yang-Mills theory.

Everything must be taken into account. If the fact will not fit the theory---let the theory go.

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.

To an intellectual who is adrift in politics, a theory is an aim; to a true politician his theory is a boundary

Socrates thought and so do I that the wisest theory about the gods is no theory at all.

String theory is not the only theory that can accommodate extra dimensions, but it certainly is the one that really demands and requires it.

The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory are vibrating the particles, vibrating the forces of nature into existence, those vibrations are sort of like musical notes. So string theory, if it's correct, would be playing out the score of the universe.

Theory and practice sometimes clash. And when that happens, theory loses. Every single time.

Quantum entanglement allows you to send information faster than light, which upset Einstein. But Einstein has the last laugh. The information you send on quantum entanglement is random, useless information. So Einsein still has the last laugh.

I have emphasized experiments more than theory. Of course, we need some theory when thinking of soft matter.

The first theory is that if we make the rich richer, somehow they will let a part of their prosperity trickle down to the rest of us. The second theory was the theory that if we make the average of mankind comfortable and secure, their prosperity will rise upward through the ranks.

If you can't think of an observation that could disprove a theory, that theory simply isn't scientific.

Criticism is concerned with evaluation. There may be evaluative principles implicit in this or that form of theory, but theory in and of itself is not prescriptive.

I suspect there could be life and intelligence out there in forms we can't conceive. Just as a chimpanzee can't understand quantum theory, it could be there as aspects of reality that are beyond the capacity of our brains They could be staring us in the face and we just Don't recognise them. The problem is that we-re looking for something very much like us, assuming that they at least have something like the same mathematics and technology.

There is the theory that all the living forms in the world have arisen from a single source which itself came from an inorganic form. This theory can be called the 'general theory of evolution,' and the evidence which supports this is not sufficiently strong to allow us to consider it as anything more than a working hypothesis.

Schrödinger's cat has a 50% quantum chance of coming out of the box alive and a 50% quantum chance of coming out dead. If you got in the box with it, the same would apply to you. So you really don't want to do that.

In these researches I followed the principles of the experimental method that we have established, i.e., that, in presence of a well-noted, new fact which contradicts a theory, instead of keeping the theory and abandoning the fact, I should keep and study the fact, and I hastened to give up the theory.

The theory of our modern technic shows that nothing is as practical as theory.

And, partly, I had found that theory-structure was a superpower in helping one get what one wanted. As I had early discovered in school wherein I had excelled without labor, guided by theory, while many others, without mastery of theory failed despite monstrous effort. Better theory I thought had always worked for me and, if now available could make me acquire capital and independence faster and better assist everything I loved.

I have always been slightly suspicious of the theory of evolution because of its ability to account for any property of living beings (the long neck of the giraffe, for example). I have therefore tried to see whether biological discoveries over the last thirty years or so fit in with Darwin's theory. I do not think that they do. To my mind, the theory does not stand up at all.

Today the theory of evolution is about as much open to doubt as the theory that the earth goes round the sun.

New knowledge has led to the recognition in the theory of evolution of more than a hypothesis. It is indeed remarkable that this theory has been progressively accepted by researchers, following a series of discoveries in various fields of knowledge. The convergence, neither sought nor fabricated, of the results of work that was conducted independently is in itself a significant argument in favor of this theory.

Men follow their sentiments and their self-interest, but it pleases them to imagine that they follow reason. And so they look for, and always find, some theory which, a posteriori, makes their actions appear to be logical. If that theory could be demolished scientifically, the only result would be that another theory would be substituted for the first one, and for the same purpose.

Those who promote the politically correct theory are favored with billions from government grants and neo-Marxist environmentalist largesse, and official recognition and award. Faked and tampered data and evidence has arisen in favor of the politically correct theory. Is not man-caused, catastrophic global warming now the only theory allowed to be taught in the West?

Our best theory of describing space at a fundamental level is probably string theory.

You believe in the God who plays dice, and I in complete law and order in a world that objectively exists, and which I, in a wildly speculative way, am trying to capture. ... Even the great initial success of the quantum theory does not make me believe in the fundamental dice-game, although I am well aware that our younger colleagues interpret this as a consequence of senility. No doubt the day will come when we will see whose instinctive attitude was the correct one.

If everything is made up of little particles and all the little particles follow quantum mechanics, then shouldn't everything just follow quantum mechanics?

To an intellectual who is adrift in politics, a theory is an aim; to a true politician his theory is a boundary.

Evolution is a fact. It is the best explanation of what is known from observations. It's a theory as powerful as the theory of gravity.

For decades, my research was driven by outstanding problems in macroeconomics: mainly growth theory and employment theory.

Whether or not you can observe a thing depends upon the theory you use. It is the theory which decides what can be observed.

The basic theory in twistor theory is not to add extra dimensions.

"Interactive Decision Theory" would perhaps be a more descriptive name for the discipline usually called Game Theory.

You've heard me talk about the quantum realm in Ant-Man which was certainly designed for that movie and for that story to take the notion of somebody who has the ability to shrink to another level we've never seen before, but as we were doing that, and studying it and talking to the science advisors who are always more than willing to spend an afternoon with us and talk about these amazing things - the quantum realm is another dimension.

Bohm's interpretation of quantum physics indicated that at the subquantum level, the level in which the quantum potential operated, location ceased to exist. All points in space became equal to all other points in space, and it was meaningless to speak of anything as being separate from anything else. Physicists call this property 'nonlocality.'

From the point of view of logic, my report on 'Exclusion principle and quantum mechanics' has no conclusion. I believe that it will only be possible to write the conclusion if a theory will be established which will determine the value of the fine structure constant and will thus explain the atomistic structure of electricity, which is such an essential quality of all atomic sources of electric fields actually occurring in nature.

A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.

No theory changes what it is a theory about; man remains what he has always been.

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.

Democracy, the deceitful theory that the Jew would insinuate - namely, that theory that all men are created equal.

The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.

Economists can never be free of from difficulties unless they will distinguish between a theory and the application of a theory.

Falsifiability for a theory is great, but a theory can still be respectable even if it is not falsifiable, as long as it is verifiable.

The electron is a theory. But the theory is so good we can almost consider them real.

To understand the theory which underlies all things is not sufficient. Theory is but the preparation for practice.

There can be no theory of any account unless it corroborate with the theory of the earth.

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.

Experience by itself teaches nothing... Without theory, experience has no meaning. Without theory, one has no questions to ask. Hence, without theory, there is no learning.

The theory of evolution, like the theory of gravity, is a scientific fact.

As an artist, there's a sweet, jump-starting quality to [marijuana] for me. I've often felt telepathic and receptive to inexplicable messages my whole life. I can stave those off when I'm not high. When I'm high - well, they come in and there's less of a veil, so to speak. So if ever I need some clarity, or a quantum leap in my own consciousness, or a quantum leap in terms of writing something or getting an answer, it's a quick way for me to get it.

When I was in high school, I was really into string theory and superstring theory and read 'Scientific American.' It's fascinating.
