SCIENCE: A discipline, or topic of study, that uses the scientific method to investigate and explain the operation of the world by testing and verifying hypothesized relationships. While the term science is often used in reference to the physical sciences, including chemistry, physics, and biology, it's also relevant to social sciences, including economics, sociology, and political science. The reason is that science is not really a subject, but a method of investigation--the scientific method. The scientific method is uses theories to derived hypotheses which are verified against real world data.
