Branches of science

The branches of science, also referred to as sciences, "scientific fields", or "scientific disciplines," are commonly divided into three major groups:

• Formal sciences: the study of formal systems, such as those under the branches of logic and mathematics, which use an a priori, as opposed to empirical, methodology.
• Natural sciences: the study of natural phenomena (including cosmological, geological, physical, chemical, and biological factors of the universe). Natural science can be divided into two main branches: physical science and life science (or biological science).
• Social sciences: the study of human behavior in its social and cultural aspects
