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:
“Like everything metaphysical the harmony between thought and reality is to be found in the grammar of the language.”
—Ludwig Wittgenstein (1889–1951)
“A country survives its legislation. That truth should not comfort the conservative nor depress the radical. For it means that public policy can enlarge its scope and increase its audacity, can try big experiments without trembling too much over the result. This nation could enter upon the most radical experiments and could afford to fail in them.”
—Walter Lippmann (1889–1974)
“We must have a real living determination to reach holiness. “I will be a saint” means I will despoil myself of all that is not God; I will strip my heart of all created things; I will live in poverty and detachment; I will renounce my will, my inclinations, my whims and fancies, and make myself a willing slave to the will of God.”
—Mother Teresa (b. 1910)
