IJSO2016, INDONESIA - Science is a systematic enterprise that creates, 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. The formal sciences are often excluded as they do not depend on empirical observations. Disciplines which use science like engineering and medicine may also be considered to be applied sciences.
