Science is applied or pure. Applied science is a knowledge of facts, events, or phenomena, as explained, accounted for, or produced, by means of powers, causes, or laws. Pure science is the knowledge of these powers, causes, or laws, considered apart, or as pure from all applications. Both these terms have a similar and special signification when applied to the science of quantity; as, the applied and pure mathematics. Exact science is knowledge so systematized that prediction and verification, by measurement, experiment, observation, etc., are possible. The mathematical and physical sciences are called the exact sciences.
