Experimental Proof Quotes

The test of all knowledge is experiment. Experiment is the sole judge of scientific truth.

We are certainly not to relinquish the evidence of experiments for the sake of dreams and vain fictions of our own devising; nor are we to recede from the analogy of Nature, which is wont to be simple and always consonant to itself.

There are two ways of forming an opinion. One is the scientific method; the other, the scholastic. To the scientific mind, experimental proof is all-important, and theory is merely a convenience in description, to be junked when it no longer fits. To the academic mind, authority is everything, and facts are junked when they do not fit theory.

Even one well-made observation will be enough in many cases, just as one well-constructed experiment often suffices for the establishment of a law.

My Design in this Book is not to explain the Properties of Light by Hypotheses, but to propose and prove them by Reason and Experiments: In order to which, I shall premise the following Definitions and Axioms.

A single test which proves some piece of theory wrong is more valuable than a hundred tests showing that idea might be true.

Never will the doctrine of spontaneous generation recover from the mortal blow struck by this simple experiment.

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.

Imagination should give wings to our thoughts but we always need decisive experimental proof, and when the moment comes to draw conclusions and to interpret the gathered observations, imagination must be checked and documented by the factual results of the experiment.

By the time 1967 had rolled around, general relativity had been relegated to mathematics departments... in most people's minds, it bore no relation to physics. And that was mostly because experiments to prove it were so hard to do - all these effects that Einstein's theory had predicted were infinitesimally small.

It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong.

You make observations, write theories to fit them, try experiments to disprove the theories and, if you can't, you've got something.

But the best demonstration by far is experience, if it go not beyond the actual experiment.

Our experiments not only proved the existence of a nervous apparatus in the above-mentioned glands, but also disclosed some facts clearly showing the participation of these nerves in normal activity.

The beautiful is the experimental proof that the incarnation is possible.

It is very different to make a practical system and to introduce it. A few experiments in the laboratory would prove the practicability of system long before it could be brought into general use. You can take a pipe and put a little coal in it, close it up, heat it and light the gas that comes out of the stem, but that is not introducing gas lighting. I'll bet that if it were discovered to-morrow in New York that gas could be made out of coal it would be at least five years before the system would be in general use.

In physics, opinions don't matter, only demonstrated experiments. The day the fellow succeeds, if ever, he won't need anybody else's opinion.

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.

Trust not my reading, nor my observations, Which with experimental seal do warrant The tenor of my book.

Experimentally, we now have demonstrated that Einstein's theory is right in strong gravitational fields. That's important to a lot of people.

My opinion - nay more, my conviction - is that, in the present state of science, as you rightly say, spontaneous generation is a chimera; and it would be impossible for you to contradict me, for my experiments all stand forth to prove that spontaneous generation is a chimera.
