Philippine Sea Plate

The Philippine Sea Plate is a small, mostly submerged oceanic tectonic plate beneath the Philippine Sea between Japan, the Mariana Islands, Indonesia, and the Philippines, bounded almost entirely by subduction zones.

Philippine Standard Time

Philippine Standard Time, also called Philippine Time (Pamantayang Oras ng Pilipinas), is the official time of the Philippines, fixed at UTC+08:00 year-round and maintained by the government agency PAGASA.

Philippine Statistics Authority

The Philippine Statistics Authority (PSA) is the central statistical agency of the Philippines, created in 2013 to merge four statistical agencies; it conducts national censuses, civil registration, and the PhilSys identification system.

Philosophiæ Naturalis Principia Mathematica

Philosophiæ Naturalis Principia Mathematica, usually shortened to the Principia, is a three-book Latin treatise by Isaac Newton, first published in London in 1687, that sets out the laws of motion and the law of universal gravitation.

Philosophical Transactions of the Royal Society

Philosophical Transactions of the Royal Society is the world's first and longest-running scientific journal, founded by Henry Oldenburg in March 1665 and split into A and B series in 1887.

Philosophical zombie

A philosophical zombie, or P-zombie, is a thought experiment in philosophy of mind: a being physically identical to a human yet lacking conscious experience entirely.

Philosophy of perception

The philosophy of perception is the branch of philosophy concerned with the nature of perceptual experience, and its central problem is reconciling obvious truths about experience with illusions and hallucinations.

Philosophy of physics

Philosophy of physics is the philosophical and conceptual study of major physical theories, including quantum mechanics, statistical mechanics, and space-time, gravity, and cosmology, with its central problem the quantum measurement problem.

Philosophy of science

Philosophy of science, also called theory of science, is the branch of philosophy concerned with how science works: what makes it science, how theories are tested, and what explanation is.

Philosophy of Science Association

The Philosophy of Science Association (PSA), founded in 1933, is an international organization promoting research in the philosophy of science and hosting the world's largest meeting of philosophers of science.

PHITS

PHITS (Particle and Heavy Ion Transport code System) is a general-purpose Monte Carlo particle transport simulation code developed by JAEA and other Japanese institutes, first released in 2002.

Phlegraean Fields

The Phlegraean Fields (Campi Flegrei) is a large active volcanic caldera west of Naples, Italy, where about 400,000 people live amid ongoing ground uplift and earthquakes.

Phlogiston theory

Phlogiston theory was a superseded chemical theory, dominant in the eighteenth century, which explained combustion, calcination, and respiration as release of a fire-like principle called phlogiston.

Phlogopite

Phlogopite is a magnesium-rich mica mineral, typically brown, that forms the magnesium end-member of the biotite series and, with muscovite, is one of only two commercially used micas.

Phlorizin

Phlorizin, also spelled phloridzin, is a glucoside found in apple trees that inhibits the glucose transporters SGLT1 and SGLT2, inducing urinary glucose loss, and served as the lead compound for SGLT2 inhibitor diabetes drugs.
