Physics (from Greek from φυσικός (physikos): natural, from φύσις (physis): Nature) is the study of energy and its interaction with matter (see chemistry, biology). Because of the primacy of energy in terms of the history of the universe, because all matter must interact with energy to express its properties and engage in transformations, and because energy is the key player when matter is decomposed into its most basic parts, physics is often considered to be the fundamental science.
