Quotes on Experiments

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.

...the proposed air force and army experiments were designed so that many animals would suffer and die without any certainty that this suffering and death would save a single human life or benefit humans in any way at all; but the same can be said of millions of their experiments performed each year in the United States alone.

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.

The ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.

When people are suicidal, their thinking is paralyzed, their options appear spare or nonexistent, their mood is despairing, and hopelessness permeates their entire mental domain. The future cannot be separated from the present, and the present is painful beyond solace. ‘This is my last experiment,’ wrote a young chemist in his suicide note. ‘If there is any eternal torment worse than mine I’ll have to be shown.

Doing for people what they can and ought to do for themselves is a dangerous experiment. In the last analysis, the welfare of the workers depends upon their own initiative. Whatever is done under the guise of philanthropy or social morality which in any way lessens initiative is the greatest crime that can be committed against the toilers. Let social busybodies and professional "public morals experts" in their fads reflect upon the perils they rashly invite under this pretense of social welfare.

Simultaneous contrast is not just a curious optical phenomenon – it is the very heart of painting. Repeated experiments with adjacent colors will show that any ground subtracts its own hue from the colors which it carries and therefore influences.

Experiments with animals have long been handicapped by our anthropocentric attitude: We often test them in ways that work fine with humans but not so well with other species.

No isolated experiment, however significant in itself, can suffice for the experimental demonstration of any natural phenomenon; for the "one chance in a million" will undoubtedly occur, with no less and no more than its appropriate frequency, however surprised we may be that it should occur to us.

It is inexcusable for scientists to torture animals; let them make their experiments on journalists and politicians.

It is the weight, not numbers of experiments that is to be regarded.

Because of how much movies cost, it's dangerous to be experimental on one film after the other. But we can experiment with television. We can do things that are fringe and bring ideas to the table that are offbeat and original.

Until politics are a branch of science, we shall do well to regard political and social reforms as experiments rather than short-cuts to the millennium.

Now I know what the atom looks like.

To learn anything other than the stuff you find in books, you need to be able to experiment, to make mistakes, to accept feedback, and to try again. It doesn't matter whether you are learning to ride a bike or starting a new career, the cycle of experiment, feedback, and new experiment is always there.

...great difficulties are felt at first and these cannot be overcome except by starting from experiments .. and then be conceiving certain hypotheses ... But even so, very much hard work remains to be done and one needs not only great perspicacity but often a degree of good fortune.

It is useful that while mankind are imperfect there should be different opinions, so is it that there should be different experiments of living; that free scope should be given to varieties of character, short of injury to others.

Science is often misrepresented as "the body of knowledge acquired by performing replicated controlled experiments in the laboratory." Actually, science is something broader: the acquisition of reliable knowledge about the world.

No experiment can be more interesting than that we are now trying, and which we trust will end in establishing the fact, that man may be governed by reason and truth. Our first object should therefore be, to leave open to him all the avenues to truth. The most effectual hitherto found, is the freedom of the press. It is, therefore, the first shut up by those who fear the investigation of their actions.

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.

The true method of knowledge is experiment.
