This encyclopedic work compiles more than 1,200 laws and models found in science and engineering literature. Written in a clear, accessible style, each entry includes a statement of the law or model, its date, keywords, a brief biography of the people involved in its formulation, sources of information, and cross-references. The author includes models not usually found in such compilations, such as dimensionless groups, models from more recently evolved areas of engineering, and models from education and business.
