The ancient Greek δείκνυμι, deiknymi, 'thought experiment', "was the most ancient pattern of mathematical proof", and existed before Euclidean mathematics, [7] where the emphasis was on the conceptual, rather than on the experimental part of a thought experiment.
In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior of both classical particles and classical waves.This type of experiment was first performed by Thomas Young in 1801, as a demonstration of the wave behavior of visible light. [1]
The Eötvös experiment was a physics experiment that measured the correlation between inertial mass and gravitational mass, demonstrating that the two were one and the same, something that had long been suspected but never demonstrated with the same accuracy.
Research design refers to the overall strategy utilized to answer research questions. A research design typically outlines the theories and models underlying a project; the research question(s) of a project; a strategy for gathering data and information; and a strategy for producing answers from the data.

The Stanford prison experiment (SPE) was a controversial psychological experiment performed during August 1971.It was designed to be a two-week simulation of a prison environment that examined the effects of situational variables on participants' reactions and behaviors.
