Science

As quoted in the Wikipedia article on science, "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. In an older and closely related meaning, "science" refers to the body of reliable knowledge itself, of the type that can be logically and rationally explained."
