A thought experiment (from the German term Gedankenexperiment, coined by Hans Christian Ørsted) in the broadest sense is the use of an imagined scenario to help us understand the way things really are. The understanding comes through reflection on the situation. Thought experiment methodology is a priori, rather than empirical, in that it does not proceed by observation or physical experiment.
Thought experiments are well-structured hypothetical questions that employ "What if?" reasoning (see irrealis moods).
Thought experiments have been used in philosophy, physics, and other fields. They have been used to pose questions in philosophy at least since Greek antiquity, some pre-dating Socrates. In physics and other sciences many famous thought experiments date from the 19th and especially the 20th Century, but examples can be found at least as early as Galileo.

@kiwinerd wow thanks. what apparatus measures the quantum wavelength of a single atom or molecule? or are these thought experiments?

Did 10 psychology experiments and analyzed results for my sister, 30% of her grade she waited all semester, i thought I was done with school

Enjoying reading the evolution of thought with the experiments @DavideZordan is doing with #MVVM & MEF in Silverlight. http://bit.ly/7UxTCI

Had a good dinner: lots of laughing. Also, talking about random thought experiments and black holes w/ little sister. Good time ;D
