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.

The use of a sequence of experiments, where the design of each may depend on the results of previous experiments, including the possible decision to stop experimenting, is within the scope of sequential analysis, a field that was pioneered [12] by Abraham Wald in the context of sequential tests of statistical hypotheses. [13]
Used to detect the presence of a ligand (commonly a protein) in a liquid sample using antibodies directed against the protein to be measure: Biochemistry, Molecular biology: Gene knockout: Used to make one of an organism's genes inoperative ("knocked out" of the organism) Molecular biology, Genetics: Immunostaining
The sample or group receiving the drug would be the experimental group (treatment group); and the one receiving the placebo or regular treatment would be the control one. In many laboratory experiments it is good practice to have several replicate samples for the test being performed and have both a positive control and a negative control .
The following two categories are variable, including for example historical articles and speeches: [4] Nonscientific material: This type of material comes from the result of an article being published. [clarification needed] It does not advance an article scientifically but instead contributes to its reputation as a scientific article.
1021 – Ibn al-Haytham (Alhacen) pioneers the experimental scientific method and experimental physics in his Book of Optics, where he devises the first scientific experiments on optics, including the first use of the camera obscura to prove that light travels in straight lines and the first experimental proof that visual perception is caused ...
In scientific research, an experimental system is the physical, technical and procedural basis for an experiment or series of experiments. Historian of science Hans-Jörg Rheinberger defines an experimental system as: "A basic unit of experimental activity combining local, technical, instrumental, institutional, social, and epistemic aspects."
