Discoveries in physics find applications throughout the other natural sciences as they regard the basic constituents of the Universe.
The structure, reactivity, and properties of a chemical compound are determined by the properties of the underlying molecules, which can be described by areas of physics such as quantum mechanics (called in this case quantum chemistry), thermodynamics, and electromagnetism. (Refer to Branches of physics) For instance, electrical engineering is the study of the practical application of electromagnetism.
