A Quote by Pierre-Gilles de Gennes

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

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.

Stephen Hawking

The importance of group theory was emphasized very recently when some physicists using group theory predicted the existence of a particle that had never been observed before, and described the properties it should have. Later experiments proved that this particle really exists and has those properties.

Irving Adler

Creationists reject Darwin's theory of evolution on the grounds that it is "just a theory". This is a valid criticism: evolution is indeed merely "a theory", albeit one with ten billion times more credence than the theory of creationism - although, to be fair, the theory of creationism is more than just a theory. It's also a fairy story. And children love fairy stories, which is presumably why so many creationists are keen to have their whimsical gibberish taught in schools.

Charlie Brooker

The more evolutionary theory gets called an atheistic theory, the greater the risk that it will lose its place in public school biology courses in the United States. If the theory is thought of in this way, one should not be surprised if a judge at some point decides that teaching evolutionary theory violates the Constitutional principle of neutrality with respect to religion.

Elliott Sober

Catastrophe Theory is-quite likely-the first coherent attempt (since Aristotelian logic) to give a theory on analogy. When narrow-minded scientists object to Catastrophe Theory that it gives no more than analogies, or metaphors, they do not realise that they are stating the proper aim of Catastrophe Theory, which is to classify all possible types of analogous situations.

Rene Thom

I didn't know so well chess theory, the theory of chess openings. And so, of course I knew the theory, but not on the level of the best players, so this was my... this was always my weakness.

Anatoly Karpov

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.

Albert Einstein

Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics.

Carl Friedrich von Weizsacker

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.

Gerald A. Kerkut

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.

Marina Abramovic

If the theory accurately predicts what they [scientists] see, it confirms that it's a good theory. If they see something that the theory didn't lead them to believe, that's what Thomas Kuhn calls an anomaly. The anomaly requires a revised theory - and you just keep going through the cycle, making a better theory.

Clayton Christensen

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.

Michio Kaku

If you're a physicist, for heaven's sake, and here is the experiment, and you have a theory, and the theory doesn't agree with the experiment, then you have to cut out the theory. You were wrong with the theory.

Ivar Giaever

You have all this education theory, and people try to make larger statements than maybe what their data would back up, because they've done these small experiments that are tied to a very particular case with a very particular implementation... theory definitely matters, but I think dogma matters less.

Sal Khan

What is especially striking and remarkable is that in fundamental physics a beautiful or elegant theory is more likely to be right than a theory that is inelegant.
