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.

Famous quotes containing the words philosophy and/or physics:
“A new philosophy generally means in practice the praise of some old vice.”
—Gilbert Keith Chesterton (1874–1936)
“He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.”
—Henry David Thoreau (1817–1862)
