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:
“I thought I alone suffered,
but suffering is everywhere.
When I went on the housetop
I saw its fire in every home.”
—Farid (13th cent.)
“The true thrift is always to spend on the higher plane; to invest and invest, with keener avarice, that he may spend in spiritual creation, and not in augmenting animal existence. Nor is the man enriched, in repeating the old experiments of animal sensation; nor unless through new powers and ascending pleasures he knows himself by the actual experience of higher good to be already on the way to the highest.”
—Ralph Waldo Emerson (1803–1882)
“Freedom is but the possibility of a various and indefinite activity; while government, or the exercise of dominion, is a single, yet real activity. The longing for freedom, therefore, is at first only too frequently suggested by the deep-felt consciousness of its absence.”
—Karl Wilhelm Von Humboldt (1767–1835)
