A Quote by Werner Heisenberg

It is true that in quantum theory we cannot rely on strict causality. But by repeating the experiments many times, we can finally derive from the observations statistical distributions, and by repeating such series of experiments, we can arrive at objective statements concerning these distributions.

Classical physics has been superseded by quantum theory: quantum theory is verified by experiments.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

Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.

James Bryant Conant

I venture to define science as a series of interconnected concepts and conceptual schemes arising from experiment and observation and fruitful of further experiments and observations. The test of a scientific theory is, I suggest, its fruitfulness.

James Bryant Conant

It seems to me that we must make a distinction between what is "objective" and what is "measurable" in discussing the question of physical reality, according to quantum mechanics. The state-vector of a system is, indeed, not measurable , in the sense that one cannot ascertain, by experiments performed on the system, precisely (up to proportionality) what the state is; but the state-vector does seem to be (again up to proportionality) a completely objective property of the system, being completely characterized by the results it must give to experiments that one might perform.

Roger Penrose

Science emerges from the other progressive activities of man to the extent that new concepts arise from experiments and observations, and that the new concepts in turn lead to further experiments and observations.

James Bryant Conant

I wish that one would be persuaded that psychological experiments, especially those on the complex functions, are not improved [by large studies]; the statistical method gives only mediocre results; some recent examples demonstrate that. The American authors, who love to do things big, often publish experiments that have been conducted on hundreds and thousands of people; they instinctively obey the prejudice that the persuasiveness of a work is proportional to the number of observations. This is only an illusion.

Alfred Binet

I argue that experiments have no special ability to produce more credible knowledge than other methods, and that actual experiments are frequently subject to practical problems that undermine any claims to statistical or epistemic superiority.

Angus Deaton

I can envision observations and experiments that would disprove any evolutionary theory I know.

Stephen Jay Gould

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

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.

Francisco J. Ayala

I think it's science and physics are just starting to learn from all these experiments. These experiments have been carried out hundreds and hundreds of times in all sorts of ways that no physicist really questions the end point. I think that these experiments are very clearly telling us that consciousness is limitless and the ultimate reality.

Robert Lanza

Growth is a process of experimentation, a series of trials, errors, and occasional victories. The failed experiments are as much as part of the process as the experiments that work.

Cherie Carter-Scott

The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle.

Werner Heisenberg

It is not necessarily true that expensive experiments are not worthwhile doing but there are plenty of rather cheap experiments which are certainly worth doing.

Martin Fleischmann

They're all gonna be considered kooks and freaks and so forth. My point here is that many in the Drive-By Media, the faces that you see (sigh), they're just are repeating what's presented to them. They're repeating what they hear when they talk to other like-minded people.

Rush Limbaugh

We can do genetics. We can do experiments on fruit flies. We can do experiments on yeast. It's not so easy to do experiments on humans. So, in fact, it helps us, to interpret our own genetic code, to have the genetic code of the other species.
