Science

n. system of knowledge gained by systematic research and organized into general laws; specific field of systematic knowledge; skill, proficiency

Science (from the Latin scientia, 'knowledge'), in the broadest sense, refers to any systematic knowledge or practice. Examples of the broader use included political science and computer science, which are not incorrectly named, but rather named according to the older and more general use of the word. In a more restricted sense, science refers to a system of acquiring knowledge based on the scientific method, as well as to the organized body of knowledge gained through such research. This article focuses on the more restricted use of the word.
