Glauber is a scientific discovery method written in the context of computational philosophy of science. It is related to machine learning in artificial intelligence. Glauber was written, among other programs, by , Herbert A. Simon, and to demonstrate how scientific discovery may be obtained by problem solving methods, in their book Scientific Discovery, Computational Explorations on the Creative Mind. Their programs simulate historical scientific discoveries based on the empirical evidence known at the time of discovery. In few words, the law: Acid + Alkali --> Salt
