In philosophy, the philosophy of physics studies the fundamental philosophical questions underlying modern physics, the study of matter and energy and how they interact. The philosophy of physics begins by reflecting on the basic metaphysical and epistemological questions posed by physics: causality, determinism, and the nature of physical law. It then turns to questions raised by important topics in contemporary physics: * Physical cosmology: space, time, and the origin and ultimate fate of the universe; * Thermodynamics and statistical mechanics: energy, work, randomness, information; * Quantum mechanics: the rival interpretations thereof, and its counterintuitive conclusions. Centuries ago, the study of causality, and of the fundamental nature of space, time, matter, and the universe were part of metaphysics. Today the philosophy of physics is essentially a part of the philosophy of science. Physicists utilize the scientific method to delineate the universals and constants governing physical phenomena, and the philosophy of physics reflects on the results of this empirical research. ==Purpose of physics== According to Niels Bohr, the purpose of physics is:〔N.Bohr, Atomic Theory and the Description of Human Knowledge (Cambridge University Press, Cambridge, 1934) p.19. Found in: R.Plaga (1997). "Proposal for an experimental test of the many-worlds interpretation of quantum mechanics". ''Foundations of Physics'', v. 27, p. 559. http://xxx.lanl.gov/abs/quant-ph/9510007v3〕 Many, particularly realists, find this minimal formulation an inadequate formulation of the purpose of physics, which they view as providing, in addition, a deeper world picture. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「philosophy of physics」の詳細全文を読む スポンサード リンク
