Science is a systematic enterprise that creates, builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Science (from the Latin scientia, meaning "knowledge") usually describes the effort to understand how the universe works through the scientific method, with observable evidence as the basis of that understanding; a way of understanding the world through thought and experimentation. The sciences tend to be positivistic in their approach to truth and knowledge, in contrast to the humanities which tend toward relativism.
