Top 1200 Scientific Theory Quotes & Sayings - Page 3

Nothing gives us greater pride than the importance of India's scientific and engineering colleges, or the army of Indian scientists at organizations such as Microsoft and NASA. Our temples are not the god-encrusted shrines of Varanasi, but Western scientific institutions like Caltech and MIT, and magazines like 'Nature' and 'Scientific American.

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.

I think that the theory of evolution is the most unscientific, faith-based, fundamentally brainless idea that ever had the misfortune to come out of a human mind. To compare it to true science is a joke. There is nothing even slightly scientific about it.

Scientific literacy is one of the underpinnings of everything I do. It's why I work with schools. It's why I teach at university. I do a lot of outreach to try and improve general scientific literacy, but the core of all scientific literacy is just literacy.

I tell personal stories associated with aspects of the theory, and I hope they are interesting and compelling. I don't feel you're going to change a grownup's mind in one reading. People have to be exposed to scientific ideas over and over again for years. It's also not a textbook.

I really don't like art where you need to know so much theory to understand. If the theory is removed, it doesn't do anything. That means that this work is an illustration of theory, and I don't believe in the power of the work itself.

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.

I think it's a theory... the theory of evolution and I don't accept it as a theory.

The scientific community says that if you even mention God as causes of anything scientific, you're gone.

It's a blessing in a scientific career - the almost daily thrill of scientific discovery.

Science ignores the spiritual realm because it is not amenable to scientific analysis. As importantly, the predictive success of Newtonian theory, emphasizing the primacy of a physical Universe, made the existence of spirit and God an extraneous hypothesis that offered no explanatory principles needed by science.

There is no scientific proof that only scientific proofs are good proofs; no way to prove by the scientific method that the scientific method is the only valid method.

Our acceptance of an ontology is, I think, similar in principle to our acceptance of a scientific theory, say a system of physics;we adopt, at least insofar as we are reasonable, the simplest conceptual scheme into which the disordered fragments of raw experience can be fitted and arranged.

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.

vivisection is not the same thing as scientific progress. There is such a thing as scientific progress. But this wholesale dedication of scientists to vivisection, which is the easy and cheap way, actually prevents them from scientific progress, for true progress is difficult and requires genius and imagination in its devoted workers.

There is a distinction, but no opposition, between theory and practice. Each to a certain extent supposes the other. Theory is dependent on practice; practice must have preceded theory.

The treatment of the indeterminacy principle as absolute and final can then be criticized as constituting an arbitrary restriction on scientific theories, since it does not follow from the quantum theory as such, but rather from the assumption of the unlimited validity of certain of its features, an assumption that can in no way ever be subjected to experimental proof.

When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.

Logic is the last scientific ingredient of Philosophy; its extraction leaves behind only a confusion of non-scientific, pseudo problems.

A hypothesis is empirical or scientific only if it can be tested by experience. A hypothesis or theory which cannot be, at least in principle, falsified by empirical observations and experiments does not belong to the realm of science.

Theory without practice is of little value, whereas practice is the proof of theory.Theory is the knowledge, practice the ability.

Only a scientific people can survive in a scientific future.

We should stop the non-scientific, pseudo-scientific, and anti-scientific nonsense emanating from the right wing, and start demanding immediate action to reduce global warming and prevent catastrophic climate change that may be on our horizon now. We must not let the [Bush] Administration distort science and rewrite and manipulate scientific reports in other areas. We must not let it turn the Environmental Protection Agency into the Environmental Pollution Agency.

scientific thought does not mean thought about scientific subjects with long names. There are no scientific subjects. The subject of science is the human universe; that is to say, everything that is, or has been, or may be related to man.

The whole [scientific] process resembles biological evolution. A problem is like an ecological niche, and a theory is like a gene or a species which is being tested for viability in that niche.

The aim of academic trade theory is to tell students, "Look at the model, not at how nations actually develop." So of all the branches of economic theory, trade theory is the most wrongheaded.

Evolution is a bankrupt speculative philosophy, not a scientific fact. Only a spiritually bankrupt society could ever believe it. Only atheists could accept this Satanic theory.

The need for general scientific understanding by the public has never been larger, and the penalty for scientific illiteracy never harsher. Lack of scientific fundamentals causes people to make foolish decisions about issues such as the toxicity of chemicals, the efficacy of medicines, the changes in the global climate.

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.

More than any other product of human scientific culture scientific knowledge is the collective property of all mankind.

The most important single thing about string theory is that it's a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That's big news.

The responsibility for the creation of new scientific knowledge - and for most of its application - rests on that small body of men and women who understand the fundamental laws of nature and are skilled in the techniques of scientific research. We shall have rapid or slow advance on any scientific frontier depending on the number of highly qualified and trained scientists exploring it.

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.

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.

We have now the remarkable spectacle that just when many scientific men are agreed that there is no part of the Darwinian system that is of any great influence, and that, as a whole, the theory is not only unproved, but impossible, the ignorant, half-educated masses have acquired the idea that it is to be accepted as a fundamental fact.

In Darwin's theory, you just have to substitute 'mutations' for his 'slight accidental variations' (just as quantum theory substitutes 'quantum jump' for 'continuous transfer of energy'). In all other respects little change was necessary in Darwin's theory...

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.

With the subsequent strong support from cybernetics , the concepts of systems thinking and systems theory became integral parts of the established scientific language, and led to numerous new methodologies and applications -- systems engineering, systems analysis, systems dynamics, and so on.

A religious creed differs from a scientific theory in claiming to embody eternal and absolutely certain truth, whereas science is always tentative, expecting that modification in its present theories will sooner or later be found necessary, and aware that its method is one which is logically incapable of arriving at a complete and final demonstration.

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.

Global warming has long since passed from scientific hypothesis to the realm of pseudo-scientific mumbo-jumbo.

It sounds paradoxical to say the attainment of scientific truth has been effected, to a great extent, by the help of scientific errors.

An important tradition within westren philosophy believes in the primacy of natural science as a guide to truth. This is sometimes met with the charge that such an allegiance amounts to scientism - the view that the only things that really exist are those recognized by fundamental physical theory, and that the only forms of genuine knowledge are scientific ones.

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.

In brief, we have the new paradigm where simulation and programs have replaced theory and observation, where government largely determines the nature of scientific activity, and where the primary role of professional societies is the lobbying of the government for special advantage.

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.

The philosopher of science is not much interested in the thought processes which lead to scientific discoveries; he looks for a logical analysis of the completed theory, including the establishing its validity. That is, he is not interested in the context of discovery, but in the context of justification.

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.

I think, that after the arrival of the mechanical clock we see an explosion in scientific thinking and scientific discovery.

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.

Scepticism and refusal of authority is at the heart of scientific endeavour. Scientific knowledge dictates economic possibilities

As time passed I became an avid reader of popular scientific books, wanting to know as much as I could about the world in which I lived. Gradually I began to see a pattern of nonsense in much scientific writing. Scientific explanations given regarding the origins or functioning of various phenomena simply didn't make sense.

I hope we find evidence of dark matter in the lab and in outer space. This would go a long way to proving the correctness of string theory, which is what I do for a living. That is my day job. So string theory is a potentially experimentally verifiable theory.

Boys can essentially wee anywhere, and my very scientific theory is that this privilege leads to some of the mind-blowing confidence they show in later life - for example, the number of guys I've known who've decided to 'give comedy a go' after finding out that I'm a comedian.

The technological overflow from scientific research has brought scientific research this bad name about carrying an irresponsibility and an alienation from God - because scientific research has led to things like the atom bomb, it's led to problems with depletion of ozone in the Earth's atmosphere, or at least it's revealed those problems.

I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done.

A mere inference or theory must give way to a truth revealed; but a scientific truth must be maintained, however contradictory it may appear to the most cherished doctrines of religion.

Before the 1940s the terms "system" and "systems thinking" had been used by several scientists, but it was Bertalanffy's concepts of an open system and a general systems theory that established systems thinking as a major scientific movement

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.

They don't hand out Ph.D.s in test piloting, but you pick up a tremendous amount of scientific and engineering knowledge along the way. After all, when you take up a brand new plane and put it through its paces to see if it will hang together, you are really flying somebody's theory.
