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 led 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 hypothesis.

Famous quotes containing the words thought, experiments and/or real:
“Last night, party at Lansdowne-House. Tonight, party at Lady Charlotte Greville’s—deplorable waste of time, and something of temper. Nothing imparted—nothing acquired—talking without ideas—if any thing like thought in my mind, it was not on the subjects on which we were gabbling. Heigho!—and in this way half London pass what is called life.”
—George Gordon Noel Byron (1788–1824)
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
“...one of my motivating forces has been to recreate the world I know into a world I wish I could be in. Hence my optimism and happy endings. But I’ve never dreamed I could actually reshape the real world.”
—Kristin Hunter (b. 1931)
