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:
“They circumcised women, little girls, in Jesus’s time. Did he know? Did the subject anger or embarrass him? Did the early church erase the record? Jesus himself was circumcised; perhaps he thought only the cutting done to him was done to women, and therefore, since he survived, it was all right.”
—Alice Walker (b. 1944)
“The trouble with tea is that originally it was quite a good drink. So a group of the most eminent British scientists put their heads together, and made complicated biological experiments to find a way of spoiling it. To the eternal glory of British science their labour bore fruit.”
—George Mikes (b. 1912)
“But the mother’s yearning, that completest type of the life in another life which is the essence of real human love, feels the presence of the cherished child even in the debased, degraded man.”
—George Eliot [Mary Ann (or Marian)
