A thought experiment or Gedankenexperiment (from German) considers some hypothesis, theory, or principle for the purpose of thinking through its consequences. Given the structure of the experiment, it may or may not be possible to actually perform it, and, in the case that it is possible for it to be performed, there need be no intention of any kind to actually perform the experiment in question. The common goal of a thought experiment is to explore the potential consequences of the principle in question.
Famous examples of thought experiments include Schrödinger's cat, illustrating quantum indeterminacy through the manipulation of a perfectly sealed environment and a tiny bit of radioactive substance, and Maxwell's demon, which attempts to demonstrate the ability of a hypothetical finite being to violate the second law of thermodynamics.

Famous quotes containing the words thought and/or experiment:
“A man is reputed to have thought and eloquence; he cannot, for all that, say a word to his cousin or his uncle. They accuse his silence with as much reason as they would blame the insignificance of a dial in the shade. In the sun it will mark the hour. Among those who enjoy his thought, he will regain his tongue.”
—Ralph Waldo Emerson (1803–1882)
“I have been trying all my life to like Scotchmen, and am obliged to desist from the experiment in despair.”
—Charles Lamb (1775–1834)
