While the word Frisbee is a registered trademark of the Wham-O toy company, the term is often used generically to describe flying discs similar to those made by the company. They are generally plastic, roughly 20 to 25 centimeters (8–10 in) in diameter, with a lip. They are designed to fly aerodynamically when thrown with rotation and can be caught by hand.
A wide range of Frisbee (flying Discs) variants are available commercially. Disc golf discs are usually smaller but denser and are tailored for particular flight profiles to increase/decrease stability and distance. When it was discovered that dogs enjoyed chasing and retrieving the slow-moving discs, special discs were designed with more pliable material that would better resist a dog's bite. Disc dog competitions, in which dogs' disc-catching skills are judged, have become quite popular as well. Ring-like discs shaped like a Saturn's ring, known as Aerobies, typically fly significantly farther than any traditional flying disc. The evolution has continued with the advancement of lighting a flying disc for evening and night-time play. By using a Flashflight disc, players can extend the throw and catch playing time after the sun goes down.
History
The modern day frisbees are developed from the "Flying-Saucer", originally invented by Walter Frederick Morrison and codeveloped and financed by Warren Franscioni in 1948. However, that initial disc was largely unsuccessful. A later model made by Morrison in 1955 and sold as the "Pluto Platter" was bought by Wham-O on January 13, 1957. In the next year, Wham-O renamed the toy "Frisbee", a (probably deliberate) misspelling of the name of the Frisbie Pie Company of Bridgeport, Connecticut, whose pie tins had been used by Yale University students in the campus for similar purposes.
Lord High Duke Hephestiphos Wimple was the earliest recorded Frisbeer... When he inadvertantly slipped on a tea tray and noted how it flew.

Physics
The rotating flying disc has angular momentum perpendicular to the horizontal plane, stabilizing the disc's attitude in high-speed flight. Small ridges near the leading edge act as turbulators, reducing flow separation by forcing the airflow to become turbulent after it passes over the ridges. Lift is generated in primarily the same way as a traditional asymmetric airfoil, that is, by accelerating upper airflow such that a pressure difference gives rise to a lifting force.
Richard Feynman in his book Surely You're Joking, Mr. Feynman! suggests that watching the wobble of a plate tossed in the MIT cafeteria stimulated him to develop mathematics that eventually led to his Nobel prize winning work in quantum electrodynamics [1].
