Thought Experiments Vs Real Experiments
"Thought" experiments are situations created in one's mind, asking a question akin to "suppose you are in this situation, assuming such is true, what would follow?". They are usually created to investigate phenomena that are not readily experienced in every-day situations. Famous examples of such thought experiments are Schrödinger's cat, the EPR thought experiment, simple illustrations of time dilation, and so on. These usually lead to real experiments designed to verify that the conclusion (and therefore the assumptions) of the thought experiments are correct. The EPR thought experiment lead to the Bell inequalities, which were then tested to various degrees of rigor, leading to the acceptance of the current formulation of quantum mechanics and probabilism as a working hypotheses.

Famous quotes containing the words thought, experiments and/or real:
“Most men are like me. They cannot live in a universe where the most bizarre thought can in one second enter into the realm of reality—where, most often, it does enter, like a knife in a heart.”
—Albert Camus (1913–1960)
“My experiments did not turn out quite like yours, Henry. But science, like love, has her little surprises.”
—William Hurlbut (1883–?)
“Sometimes among our more sophisticated, self-styled intellectuals—and I say self-styled advisedly; the real intellectual I am not sure would ever feel this way—some of them are more concerned with appearance than they are with achievement. They are more concerned with style then they are with mortar, brick and concrete. They are more concerned with trivia and the superficial than they are with the things that have really built America.”
—Lyndon Baines Johnson (1908–1973)
