Practical disciplines

Applied science is a discipline of science that applies existing scientific knowledge to develop more practical applications, like technology or inventions.

Within natural science, disciplines that are basic science, also called pure science, develop information to predict and perhaps explain—thus somehow understand—phenomena in the natural world. Applied science applies science to real world practice. This includes a broad range of applied science related fields from Engineering, Medicine to Early Childhood Education.

Applied science can also apply formal science, such as statistics and probability theory, as in epidemiology. Genetic epidemiology is an applied science applying both biological and statistical methods.

Engineering sciences include thermodynamics, heat transfer, fluid mechanics, statics, dynamics, mechanics of materials, kinematics, electromagnetism, materials science, earth sciences, engineering physics.

Medical sciences, for instance medical microbiology and clinical virology, are applied sciences that apply biology toward medical knowledge and inventions, but not necessarily medical technology, whose development is more specifically biomedicine or biomedical engineering.
