BRANCHES OF SCIENCE
The branches of science (which are also referred to as "sciences", "scientific fields", or "scientific disciplines") are commonly divided into two major groups: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being tested for its validity by other researchers working under the same conditions. There are also related disciplines that are grouped into interdisciplinary and applied sciences, such as engineeringand medicine. Within these categories are specialized scientific fields that can include parts of other scientific disciplines but often possess their own terminology and expertise
2 MAIN BRANCHES OF SCIENCE
1. Natural science is a branch of science that seeks to elucidate the rules that govern the natural world by applying an empirical and scientific method to the study of the universe. The term natural sciences is used to distinguish it from the social sciences, which apply the scientific method to study human behavior and social patterns; the humanities, which use a critical, or analytical approach to the study of the human condition; and the formal sciences, such as mathematics and logic, which use an a priori, as opposed to factual methodology to study formal systems.
2. Social sciences are the fields of scholarship that study society. "Social science" is commonly used as an umbrella term to refer to a plurality of fields outside of the natural sciences. These include:anthropology, archaeology, business administration, communication, criminology, economics, education, government, linguistics, international relations, political science and, in some contexts, geography, history,law, and psychology.
