Pyroclasic flows Pyroclastic flows are high-density mixtures of hot, dry rock fragments and hot gases that move away from the vent that erupted them at high speeds. They may result from the explosive eruption of molten or solid rock fragments, or both.
Pyroclastic fall A pyroclastic fall is a uniform deposit of material which has been ejected from an eruption or plume such as an ash fall or tuff. Pyroclastic flows occur relatively spontaneously in the geological time scale and are great indicators of time.
Pyroclastic flow Pyroclastic flows are a common and devastating result of some volcanic eruptions. They are fast-moving fluidized bodies of hot gas, ash and rock (collectively known as tephra) which can travel away from the vent at up to 150 km/h.
Pyroclastic rock Pyroclastic rocks or pyroclastics (derived from the Greek πῦρ, meaning fire, and κλαστός, meaning broken) are debris thrown from volcanoes during an eruption. It consists of fresh lava that has risen to the surface or older volcanic material that has remelted and has been expelled into the air by the explosion.
Pyroclastic surge A pyroclastic surge is a fluidized mass of turbulent gas and rock fragments which is ejected during some volcanic eruptions. It is similar to a pyroclastic flow but contains a much higher of proportion of gas to rock, which makes it more turbulent and allows it to rise up over ridges and hills rather than always travel downhill as pyroclastic flows do.
Pyrocumulous cloud A pyrocumulous cloud is a cloud that is formed by the water vapor and smoke that is given off by a large fire. The combustion products of wildfires, usually the only fires big enough to form pyrocumulous clouds, include carbon dioxide, smoke and water vapor.
Pyroelectric fusion Pyroelectric fusion is a technique for achieving nuclear fusion by using an electric field generated by pyroelectric crystals to accelerate deuterium ions (tritium might also be used someday) into a metal hydride target also containing deuterium (or tritium) with sufficient kinetic energy to cause these ions to fuse together. The novel idea with this approach to fusion is in its application of the pyroelectric effect to generate a strong electric field (gigavolts per meter), by heating the crystal from −30°C to +45°C in a few minutes.
Pyroelectricity Pyroelectricity is the ability of certain materials to generate an electrical potential when they are heated or cooled. As a result of this change in temperature, positive and negative charges move to opposite ends through migration (i.

Pyrometallurgical treatment may produce saleable products such as pure metals, or intermediate compounds or alloys, suitable as feed for further processing.
Pyrometric cone Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials. The cones, often used in sets of three as shown in the illustration, are positioned in a kiln with the wares to be fired and provide a visual indication of when the wares have reached a required state of maturity, a combination of time and temperature.
Pyrometric device Pyrometric devices gauge heatwork (the combined effect of both time and temperature) when firing materials inside a kiln. It is important to note pyrometric devices do not measure temperature, but can report temperature equivalents.

Pythagorean comma In music, when ascending from an initial (low) pitch by a cycle of justly tuned perfect fifths (ratio 3:2), leapfrogging twelve times, one eventually reaches a pitch approximately seven whole octaves above the starting pitch. If this pitch is then lowered precisely seven octaves, it will be discovered that the resulting pitch is (a very small amount over) 23.

Credited as an invention to Pythagoras of Samos, it allows the user to fill the cup with wine (the most popular beverage in Pythagoras' time) up to a certain level.
Pythagorean expectation Pythagorean expectation is a formula invented by Bill James to estimate how many games a baseball team "should" have won based on the number of runs they scored and allowed. The term is derived from the formula's resemblance to Pythagoras' formula to compute the length of the hypotenuse of a triangle from the lengths of its other two sides.
Pythagorean hammers According to legend, Pythagoras discovered the foundations of music by listening to the sounds of four blacksmith's hammers, which produced consonance and dissonance when they were struck simultaneously. Specifically, he noticed that hammer A produced consonance with hammer B when they were struck together, and hammer C produced consonance with hammer A, but hammers B and C produced dissonance with each other.
