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.
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 principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific "truth." But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations--to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess.
Richard P. Feynman
Indeed, while Nature is wonderfully inventive of new structures, her conservatism in holding on to old ones is still more remarkable. In the ascending line of development she tries an experiment once exceedingly thorough, and then the question is solved for all time. For she always takes time enough to try the experiment exhaustively. It took ages to find how to build a spinal column or brain, but when the experiment was finished she had reason to be, and was, satisfied.
John M. Tyler
In its essence the Gospel is a call to make the experiment of comradeship, the experiment of fellowship, the experiment of trusting the heart of things, throwing self-care to the winds, in the sure and certain faith that you will not be deserted, forsaken nor betrayed, and that your ultimate interests are perfectly secure in the hands of the Great Companion. This insight is the center, the kernel, the growing point of the Christian religion, which, when we have it, all else is secure, and when we have it not, all else is precarious.
L. P. Jacks
The TV scientist who mutters sadly, "The experiment is a failure; we have failed to achieve what we had hoped for," is suffering mainly from a bad script writer. An experiment is never a failure solely because it fails to achieve predicted results. An experiment is a failure only when it also fails adequately to test the hypothesis in question, when the data it produces don't prove anything one way or another.
Robert M. Pirsig
Unfortunately, all life on earth - the only life we know - represents, for all its current variety, the results of a single experiment , for every earthly species evolved from the common ancestry of a single origin. We desperately need a repetition of the experiment (several would be better, but let's not be greedy!) in order to make a judgement. Mars represents our first real hope for a second experiment - the sine qua non - for any proper answer for the question of questions.
Stephen Jay Gould
No one believes an hypothesis except its originator but everyone believes an experiment except the experimenter. Most people are ready to believe something based on experiment but the experimenter knows the many little things that could have gone wrong in the experiment. For this reason the discoverer of a new fact seldom feels quite so confident of it as others do. On the other hand other people are usually critical of an hypothesis, whereas the originator identifies himself with it and is liable to become devoted to it.
William Ian Beardmore Beveridge
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.
There wasn't a lot of R&B cats doing songs at 120 beats per minute before 'Closer,' which I take full credit and responsibility for. That's all good, but it was an experiment. You experiment with something, if it goes good, cool, but you never forget where you come from and R&B is where I come from.
You're going to die soon enough anyway; even if it's a hundred years from now, that's still the blink of a cosmic eye. In the meantime, live like a scientist - even a controversial one with only an ally or two in all the world - and treat life as a grand experiment, blood, sweat, tears and all. Bear in mind that there's no such thing as a failed experiment - only data.
He [Washington] has often declared to me that he considered our new constitution as an experiment on the practicability of republican government, and with what dose of liberty man could be trusted for his own good; that he was determined the experiment should have a fair trial, and would lose the last drop of his blood in support of it. And these declarations he repeated to me the oftener and the more pointedly.
There is one experiment which I always like to try, because it proves something whichever way it goes. A solution of iodine in water is shaken with bone-black, filtered and tested with starch paste. If the colorless solution does not turn the starch blue, the experiment shows how completely charcoal extracts iodine from aqueous solution. If the starch turns blue, the experiment shows that the solution, though apparently colorless, still contains iodine which can be detected by means of a sensitive starch test.
Wilder Dwight Bancroft
if you're doing an experiment, you should report everything that you think might make it invalid-not only what you think is right about it: other causes that could possibly explain your results; and things you thought of that you've eliminated by some other experiment, and how they worked-to make sure the other fellow can tell they have been eliminated.
Richard P. Feynman
It is better to travel with hope in one's heart than to arrive in safety. . . . We should celebrate today's failure because it is a clear sign that our voyage of discovery is not yet over. The day the experiment succeeds is the day the experiment ends. And I inevitably find that the sadness of ending outweighs the celebration of success.
Experimental science is a craft and an art, and part of the art is knowing when to end a fruitless experiment. There is a danger of becoming obsessed with a fruitless experiment even if it goes nowhere. It is always a good plan for a speculative experimenter to have two experiments going, or at least one going and one being built.
Martin Lewis Perl
They had imagined too often and too much and so they had exhausted all their possibilities. When they embraced each other's phantoms, each in his separate privacy has savoured the most refined of pleasures but, connoisseurs of unreality as they were, they could not bear the crude weight, the rank smell and the ripe taste of real flesh. It is always a dangerous experiment to act out a fantasy; they had undertaken the experiment rashly and had failed...
I thought my duty was to restore Haan, but Haan is not King Cosugi or the burned-down palace or the ruins of the great estates or the dead nobles and their descendants pining for glory-these are but parts of an experiment at a way of life for the people of Haan, her true essence. When the experiment has proven to be a failure, one must be willing to try new paths, new ways of doing things.
Anything from making a mistake on an experiment that would ruin some scientist on earth's experiment - career, potentially - to doing something wrong with the satellite that a country was depending on for its communications, to making some mistake that could actually cost you and the crew either a mission or your lives. So there is a lot of pressure that's put on every astronaut to just make sure that he or she understands exactly what to do, exactly when to do it, and is trained and prepared to carry it out.
The music industry itself is changing so quickly, that everything new, like Spotify, all feels to me a bit like a grand experiment. And I'm not willing to contribute my life's work to an experiment that I don't feel fairly compensates the writers, producers, artists, and creators of this music. And I just don't agree with perpetuating the perception that music has no value and should be free.
Mr. Thomas, did you know that in an experiment with a human observer, subatomic particles behave differently from the way they behave when the experiment is observed while in progress and the results are examined, instead, only after the fact?" "Sure. Everybody knows that." He raised one bushy eyebrow. "Everybody, you say. Well then you realize what this signifies." I said, "At least on an subatomic level, human will can in part shape reality.
It is more important to have beauty in one's equations than to have them fit experiment... It seems that if one is working from the point of view of getting beauty in one's equations, and if one has really a sound insight, one is on a sure line of progress. If there is not complete agreement between the results of one's work and experiment, one should not allow oneself to be too discouraged, because the discrepancy may well be due to minor features that are not properly taken into account and that will get cleared up with further developments of the theory.
The [Stanford Prison Experiment] was readily approved by the Human Subjects Research committee because it seemed like college kids playing cops and robbers, it was an experiment that anyone could quit at any time and minimal safeguards were in place. You must distinguish hind sight from fore sight, knowing what you know now after the study is quite different from what most people imagined might happen before the study began.
I do not think the division of the subject into two parts - into applied mathematics and experimental physics a good one, for natural philosophy without experiment is merely mathematical exercise, while experiment without mathematics will neither sufficiently discipline the mind or sufficiently extend our knowledge in a subject like physics.
The American experiment is not a theocracy and does not establish an official religion, but the Declaration of Independence and the Constitution of the United States are rooted in a Christian perspective of the nature of government and the nature of man. The challenge of the next millennium will be to preserve the American experiment by restoring its Christian perspective.
William H. Pryor
Frequently, I have been asked if an experiment I have planned is pure or applied science; to me it is more important to know if the experiment will yield new and probably enduring knowledge about nature. If it is likely to yield such knowledge, it is, in my opinion, good fundamental research; and this is more important than whether the motivation is purely aesthetic satisfaction on the part of the experimenter on the one hand or the improvement of the stability of a high-power transistor on the other.
(Coining phrase "null hypothesis") In relation to any experiment we may speak of this hypothesis as the "null hypothesis," and it should be noted that the null hypothesis is never proved or established, but is possibly disproved, in the course of experimentation. Every experiment may be said to exist only in order to give the facts a chance of disproving the null hypothesis.
I don't think that you can invent on behalf of customers unless you're willing to think long-term, because a lot of invention doesn't work. If you're going to invent, it means you're going to experiment, and if you're going to experiment, you're going to fail, and if you're going to fail, you have to think long term.
In the 1920s, there was a dinner at which the physicist Robert W. Wood was asked to respond to a toast... 'To physics and metaphysics.' Now by metaphysics was meant something like philosophy-truths that you could get to just by thinking about them. Wood took a second, glanced about him, and answered along these lines: The physicist has an idea, he said. The more he thinks it through, the more sense it makes to him. He goes to the scientific literature, and the more he reads, the more promising the idea seems. Thus prepared, he devises an experiment to test the idea. The experiment is painstaking. Many possibilities are eliminated or taken into account; the accuracy of the measurement is refined. At the end of all this work, the experiment is completed and... the idea is shown to be worthless. The physicist then discards the idea, frees his mind (as I was saying a moment ago) from the clutter of error, and moves on to something else. The difference between physics and metaphysics, Wood concluded, is that the metaphysicist has no laboratory.
In terms of getting people to experiment more and take more risk, there are at least three things that immediately come to my mind. Number one, of course, is role-modeling it yourself. Number two is when people take intelligent, smart risks and yet it doesn't work out, not shooting them. And number three, being honest with yourself. If the culture you have is radically different from an experiment and take-risk culture, then you have a big change you going to have to make""and no little gimmicks are going to do it for you.
John P. Kotter
When men have realized that time has upset many fighting faiths, they may come to believe... that the ultimate good desired is better reached by free trade in ideas- that the best test of truth is the power of the thought to get itself accepted in the competition of the market, and that truth is the only ground upon which their wishes safely can be carried out. That at any rate is the theory of our Constitution. It is an experiment. As all life is an experiment. Every year if not every day we wager our salvation upon some prophecy based upon imperfect knowledge.
Oliver Wendell Holmes Sr.

From the dawn of exact knowledge to the present day, observation, experiment, and speculation have gone hand in hand; and, whenever science has halted or strayed from the right path, it has been, either because its votaries have been content with mere unverified or unverifiable speculation (and this is the commonest case, because observation and experiment are hard work, while speculation is amusing); or it has been, because the accumulation of details of observation has for a time excluded speculation.
Thomas Henry Huxley
One of the various theories proposed to explain the negative result of the famous Michelson-Morley experiment with light waves (conceived to measure the absolute space), was based on the ballistic hypothesis, i.e. on postulating that the speed of light predicted by Maxwell's equations was not given as relative to the medium but as relative to the transmitter (firearm). Had that been the case, the experiment negative results would have not caused such perplexity and frustration (as we shall see in forthcoming sections).
Suicide may also be regarded as an experiment - a question which man puts to Nature, trying to force her to answer. The question is this: What change will death produce in a man's existence and in his insight into the nature of things? It is a clumsy experiment to make; for it involves the destruction of the very consciousness which puts the question and awaits the answer.
in microphysics the observer interferes with the experiment in a way that can't be measured and that therefore can't be eliminated. No natural laws can be formulated, saying "such-and-such will happen in every case." All the microphysicist can say is "such-and-such is, according to statistical probability, likely to happen." This naturally represents a tremendous problem for our classical physical thinking. It requires a consideration, in a scientific experiment, of the mental outlook of the participant-observer: It could this be said that scientists can no longer hope to describe any aspects or qualities of outer objects in a completely independent, "objective" manner.
M.L. von Franz
I don't use an exposure meter. My personal advice is: Spend the money you would put into such an instrument for film. Buy yards of film, miles of it. Buy all the film you can get your hands on. And then experiment with it.That is the only way to be successful in photography. Test, try, experiment, feel your way along. It is the experience, not technique, which counts in camera work first of all. If you get the feel of photography, you can take fifteen pictures while one of your opponents is trying out his exposure meter.
There is only one motive for writing a novel: to be published and read. To me there is no distinction between the mystery novel and the novel, only between good books and bad books. A good book takes the reader into a new world of experience; it is an experiment. A bad book, unless the writing is inept, reinforces the intransigent attitude of the reader not to experiment with a new world. Since there are criminals and psychopaths and sociopaths in all my novels they are in a way psychological thrillers.
John Franklin Bardin
The main thesis of mind-physics holds that consciousness and matter are both manifestations of a more primary entity, and that the processes of manifestation exhibit equivalent invariances for both consciousness and matter. When the program for mind-physics is complete the subject-object dichotomy of modal logic, the polarity of concept-percept, and the antagonism between morality and technology will all come to an end. Then the non-repeatable experiment will be understood to be more primary than the traditional repeatable experiment.
Those who have handled sciences have been either men of experiment or men of dogmas. The men of experiment are like the ant, they only collect and use; the reasoners resemble spiders, who make cobwebs out of their own substance. But the bee takes a middle course: it gathers its material from the flowers of the garden and of the field, but transforms and digests it by a power of its own. Not unlike this is the true business of philosophy; for it neither relies solely or chiefly on the powers of the mind, nor does it take the matter which it gathers from natural history and mechanical experiments and lay it up in the memory whole, as it finds it, but lays it up in the understanding altered and digested.
True art is by nature moral. We recognize true art by its careful, thoroughly honest search for and analysis of values. It is not didactic because, instead of teaching by authority and force, it explores, open-mindedly, to learn what it should teach. It clarifies, like an experiment in a chemistry lab, and confirms. As a chemist's experiment tests the laws of nature and dramatically reveals the truth or falsity of scientific hypotheses, moral art tests valyes and rouses trustworthy feelings about the better and the worse in human action.
Having learnt from experiment and argument that a stone falls downwards, a man indubitably believes this, and always expects the law he has learnt to be fulfilled. But learning just as certainly that his will is subject to laws, he does not and cannot believe it. However often experiment and reasoning may show a man that under the same conditions and with the same character he will do the same thing as before, yet when, under the same conditions and with the same character, he approaches for the thousandth time the action that always ends in the same way, he feels as certainly convinced as before the experiment that he can act as he pleases. Every man, savage or sage, however incontestably reason and experiment may prove to him that it is impossible to imagine two different courses of action in precisely the same conditions, feels that without this irrational conception (which constitutes the essence of freedom) he cannot imagine life. He feels that, however impossible it may be, it is so, for without this conceptions of freedom not only would he be unable to understand life, but he would be unable to live for a single moment. He could not live, because all man's efforts, all his impulses to life, are only efforts to increase freedom. Wealth and poverty, fame and obscurity, power and subordination, strength and weakness, health and disease, culture and ignorance, work and leisure, repletion and hunger, virtue and vice, are only greater or lesser degrees of freedom. A man having no freedom cannot be conceived of except as deprived of life. If the conception of freedom appears to reason a senseless contradiction, like the possibility of performing two actions at one and the same instant of time, or of an effect without a cause, that only proves that consciousness is not subject to reason.
