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.^[1][2]

The branches of science, also referred to as scientific fields, scientific disciplines, or just sciences, can be arbitrarily divided into three major groups:

• The natural sciences (biology, chemistry, physics, astronomy, and Earth sciences), which study nature in the broadest sense;
• The social sciences (e.g. psychology, sociology, economics, history) which study people and societies; and
• The formal sciences (e.g. mathematics, logic, theoretical computer science), which study abstract concepts.

Disciplines that use science, such as engineering and medicine, are described as applied sciences.
