A Quote by Steven Weinberg
It appears that anything you say about the way that theory and experiment may interact is likely to be correct, and anything you say about the way that theory and experiment must interact is likely to be wrong.

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.
A theory can be proved by experiment; but no path leads from experiment to the birth of a theory.
Theory said one thing and the experiment said something different, so that was the stimulus that started me going, that there was something there to be explained, which wasn't understood and to try to see why that experiment gave the answer it did, so it was a big opportunity for a young student starting to have actually an experiment which contradicted the theory, so that's was my chance to understand that.
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.
I think drama in schools shouldn't be about, 'Let's put 'Annie' on this year' - not that there's anything wrong with that - but it's a good way of getting kids to interact, and it can be a good communication tool.
I never have, above my signature, announced anything that I did not prove first. That is the reason why no statement of mine was ever contradicted, and I do not think it will be, because whenever I publish something I go through it first by experiment, then from experiment I calculate, and when I have the theory and practice meet I announce the results.
So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested.
I prefer to connect with fans from the stage. Like, I don't have a Twitter page, or anything like that. So for me, that's what the show is about. For me - is a way to interact with fans; being up onstage and showing them, through music - which is all I really know - the best way to say thank you.
The scientific theorist is not to be envied. For Nature, or more precisely experiment, is an exorable and not very friendly judge of his work. It never says "yes" to a theory. In the most favorable cases it says "Maybe," and in the great majority of cases simply "No." If an experiment agrees with a theory it means for the latter "Maybe," and if it does not agree it means "No." Probably every theory will some day experience its "No" - most theories, soon after conception.
Indeed, this epistemological theory of the relation between theory and experiment differs sharply from the epistemological theory of naive falsificationism.
Although this may seem a paradox, all exact science is dominated by the idea of approximation. When a man tells you that he knows the exact truth about anything, you are safe in inferring that he is an inexact man. Every careful measurement in science is always given with the probable error ... every observer admits that he is likely wrong, and knows about how much wrong he is likely to be.
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. A theory appears to be beautiful or elegant (or simple, if you prefer) when it can be expressed concisely in terms of mathematics we already have. Symmetry exhibits the simplicity. The Foundamental Law is such that the different skins of the onion resemble one another and therefore the math for one skin allows you to express beautifully and simply the phenomenon of the next skin.
To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
I feel drawn to experiment with ways that technology can interact with notions of intimacy, because so much of technology is done in a way that's very cold and has such an opposite effect.
They say, "Katie, you're wrong." And if I say, "How dare you say that? I have studied and studied." Or, "I am an expert in" whatever area we're talking about. Or, "No, you are wrong! And I think you're rude!" Or anything like that, and if we don't say it out loud, maybe we think it, but that's stressful. The moment I've defended, in any way, I've started the war.
The good thing about Twitter is that theres not so much of a wall between you and your fan base. They can interact with you, and it makes them more endeared to you when you interact with them. Its really fun in that way.
