A Quote by Ernst Mach
Thought experiment is in any case a necessary precondition for physical experiment. Every experimenter and inventor must have the planned arrangement in his head before translating it into fact.

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.
The value and utility of any experiment are determined by the fitness of the material to the purpose for which it is used, and thus in the case before us it cannot be immaterial what plants are subjected to experiment and in what manner such experiment is conducted.
Experiment - exercising to see the result. We planned Europa not as an experiment in this sense but as a work of art. Yet The Eye and the Ear was done as a consciously designed experiment. Not every avant-garde dealt with experiments and not every experiment equalled avant-garde.
They have never affirm'd any thing, concerning the cause, till the trial was past: whereas, to do it before, is a most venomous thing in the making of Sciences: for whoever has fix'd on his Cause, before he has experimented; can hardly avoid fitting his Experiment, and his Observations, to his Own Cause, which he had before imagin'd; rather than the Cause to the Truth of the Experiment itself. Referring to experiments of the Aristotelian mode, whereby a preconceived truth would be illustrated merely to convince people of the validity of the original thought.
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.
every short story is an experiment - what one must ask is not only, did it come off, but was it, as an experiment, worth making?
The true worth of an experimenter consists in his pursuing not only what he seeks in his experiment, but also what he did not seek.

But lest I should mislead any when I have my own head and obey my whims, let me remind the reader that I am only an experimenter.Do not set the least value on what I do, or the least discredit on what I do not, as if I pretended to settle any thing as true or false. I unsettle all things. No facts are to me sacred; none are profane; I simply experiment, an endless seeker with no Past at my back.
We must trust to nothing but facts: these are presented to us by nature and cannot deceive. We ought, in every instance, to submit our reasoning to the test of experiment, and never to search for truth but by the natural road of experiment and observation.

Experiment is actually doing the art. That's the experiment and then you get to experience the experiment.
What Mach calls a thought experiment is of course not an experiment at all. At bottom it is a grammatical investigation.
When a mathematician engaged in investigating physical actions and results has arrived at his own conclusions, may they not be expressed in common language as fully, clearly, and definitely as in mathematical formulae? If so, would it not be a great boon to such as well to express them so -- translating them out of their hieroglyphics that we might also work upon them by experiment?
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.
We must never lose sight of the fact that we must take part in the development, not only of ourselves but of all humanity... I want you to understand that there never was or has been or will be, in the minds of the founders, including myself, the thought of any reward any notice coming to us for this experiment in brotherly cooperation and comradeship, which we initiated and which has developed, not necessarily because of any efforts of ours, into one of the best regarded organizations in the Negro collegiate world.
