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 science fields from Engineering to Child Care.

Engineering sciences include for example: thermodynamics, heat transfer, fluid mechanics, statics, dynamics,mechanics of materials, kinematics, electromagnetism, materials science, earth sciences, engineering physics, and many others.

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

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.
