Science 科学
(重定向自Scientifically)
Science is a systematic enterprise that, using mathematics and measurement, creates, builds and organizes knowledge in the form of testable observations, explanations and predictions about the universe.
Contemporary science is typically subdivided into the natural sciences, which study the material world; the social sciences, which study people and societies; and the formal sciences, such as mathematics. The formal sciences are often excluded as they do not depend on empirical observations. Disciplines which use science like engineering and medicine may also be considered to be applied sciences.
