Science is a body of empirical, theoretical, and practical knowledge about the natural world, produced by researchers making use of scientific methods, which emphasize the observation, explanation, and prediction of real world phenomena by experiment. Given the dual status of science as objective knowledge and as a human construct, good historiography of science draws on the historical methods of both intellectual history and social history.
