| phospholipids | Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see glycerophosphates) or sphingosine (sphingolipids). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.

| phone |
The telephone or phone (Greek: tele = far away and phone = voice) is a telecommunications device that transmits speech by means of electric signals. Generally attributed to the inventor Alexander Graham Bell whose first device was built in Boston, Massachusetts, in 1876 the actual history is a subject of complex dispute. ...

| photometry |
Photometry is a technique of astronomy concerned with measuring the flux, or intensity of an astronomical object's electromagnetic radiation. Usually, photometry refers to measurement over large wavelength bands of radiation; but, when not only the amount of radiation but its spectral distribution are measured the term spectrophotometry is used. ...

| phoneme |
In spoken language, a phoneme is a basic, theoretical unit of sound that can distinguish words (that is, changing a phoneme in a word, produces another word, that has a different meaning). The phoneme is a basic sound segment, whose linguistic function is to distinguish a word's morphemes. Phonemes are not physical sounds, but abstractions. Phonemes are recognized as a family of phones, that are regarded as a single sound, and represented by a common symbol. ...

| phonetics |
Phonetics (from the Greek word phone = sound/voice) is the study of sounds (voice). It is concerned with the actual properties of speech sounds (phones) as well as those of non-speech sounds, and their production, audition and perception, as opposed to phonology, which operates at the level of sound systems and abstract sound units (such as phonemes and distinctive features). Phonetics deals with the sounds themselves rather than the contexts in which they are used in languages. ...

Photon was a live action series based on the infrared tag game popular in the 1980s. The series took place on Earth and in space on various worlds and involved a young human teen named Christopher Jarvis who is a champion player of Photon. He receives a mysterious message one day while playing and is transported to the ship of Mother One, the leader of the Federation of Light a galactic amalgam of beings dedicated to playing Photon and the power of good over evil. ...
