Index of branches of science
The following index is provided as an overview of and topical guide to science: Links to articles and redirects to sections of articles which provide information on each topic are listed with a short description of the topic. When there is more than one article with information on a topic, the most relevant is usually listed, and it may be cross-linked to further information from the linked page or section.
Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
The branches of science, also referred to as scientific fields, scientific disciplines, or just sciences, can be arbitrarily divided into three major groups:
- The natural sciences (biology, chemistry, physics, astronomy, and Earth sciences), which study nature in the broadest sense;
- The social sciences (e.g. psychology, sociology, economics, history) which study people and societies; and
- The formal sciences (e.g. mathematics, logic, theoretical computer science), which study abstract concepts.
Disciplines that use science, such as engineering and medicine, are described as applied sciences.
