Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Contemporary science is typically subdivided into the natural sciences which study the material world, the social sciences which study people and societies, and the formal sciences like mathematics. Some do not consider formal sciences to be true science as theories within these disciplines cannot be tested with physical observations, although others dispute this view. Disciplines which use science like engineering and medicine may also be considered to be applied sciences. Science is related to research, and is normally organized by a university, a college, or a research institute.
