History of experiments History of experiments The history of experimental research is long and varied. Indeed, the definition of an experiment itself has changed in responses to changing norms and practices within particular fields of study. This article documents the history and development of experimental research from its origins in Galileo's study of gravity into the diversely applied method in use today.

He combined observations, experiments and rational arguments to support his intromission theory of vision, in which rays of light are emitted from objects
