Specialized scientific disciplines that exist in multiple categories may include parts of other scientific disciplines but often possess their own terminologies and expertises. Natural, social, and formal science make up the fundamental sciences, which form the basis of interdisciplinarity- and applied sciences such as engineering and medicine. This verifiability may well vary even within a scientific discipline. Scientific knowledge must be based on observable phenomena and must be capable of being verified by other researchers working under the same conditions.

Social sciences: the study of human behavior in its social and cultural aspects.Natural science can be divided into two main branches: physical science and life science (or biology). Natural sciences: the study of natural phenomena (including cosmological, geological, physical, chemical, and biological factors of the universe).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.The branches of science, also referred to as sciences, scientific fields or scientific disciplines, are commonly divided into three major groups:
