For the periodical, see Science (journal)

Science in the broadest sense refers to any knowledge or trained skill, especially (but not exclusively) when this is attained by verifiable means. See the entry Science in the Oxford English Dictionary ISBN 0195222172 The word science also describes any systematic field of study or the knowledge gained from such study. In a more restricted sense, science refers to a system of acquiring knowledge based on empiricism, experimentation, and methodological naturalism, as well as to the organized body of knowledge humans have gained by such research. This article focuses on science in the latter sense.
