Wikipedia definition
2. ScienceScience (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. In an older and closely related meaning (found, for example, in Aristotle), "science" refers to the body of reliable knowledge itself, of the type that can be logically and rationally explained. Since classical antiquity science as a type of knowledge was closely linked to philosophy.
