A frisbee, also called a flying disc or simply a disc, is a gliding toy or sporting item that is generally made of injection-molded plastic and roughly 20 to 25 centimetres in diameter with a pronounced lip. It is used recreationally and competitively for throwing and catching, as in flying disc games. The shape of the disc is an airfoil in cross-section which allows it to fly by reducing the drag and increasing lift as it moves through the air, compared to a flat plate. Spinning the disc imparts a stabilizing gyroscopic force, allowing it to be both aimed with accuracy and thrown for distance.
Ralph C. Merkle is an American computer scientist and mathematician. He is one of the inventors of public-key cryptography, the inventor of cryptographic hashing, and more recently a researcher and speaker on cryonics.
William Bradford Shockley Jr. was an American inventor, physicist, and eugenicist. He was the manager of a research group at Bell Labs that included John Bardeen and Walter Brattain. The three scientists were jointly awarded the 1956 Nobel Prize in Physics for "their researches on semiconductors and their discovery of the transistor effect".

It is known for creating and marketing many popular toys for nearly 70 years, including the Hula hoop, Frisbee, Slip 'N Slide, Super Ball, Trac-Ball, Silly String, Hacky sack, Wham-O Bird Ornithopter and Boogie Board, many of which have become genericized trademarks.
The Stanford University School of Medicine is the medical school of Stanford University and is located in Stanford, California, United States. It traces its roots to the Medical Department of the University of the Pacific, founded in San Francisco in 1858. This medical institution, then called Cooper Medical College, was acquired by Stanford in 1908. The medical school moved to the Stanford campus near Palo Alto, California, in 1959.
Stanley Louis Cavell was an American philosopher. He was the Walter M. Cabot Professor of Aesthetics and the General Theory of Value at Harvard University. He worked in the fields of ethics, aesthetics, and ordinary language philosophy. As an interpreter, he produced influential works on Wittgenstein, Austin, Emerson, Thoreau, and Heidegger. His work is characterized by its conversational tone and frequent literary references.
The chakram is a throwing weapon from the Indian subcontinent. It is circular with a sharpened outer edge and a diameter of 12–30 cm (4.7–11.8 in). It is also known as chalikar meaning "circle", and was sometimes referred to in English writings as a "war-quoit". The chakram is primarily a throwing weapon, but can also be used hand-to-hand. A smaller variant called chakri is worn on the wrist. A related weapon is the chakri dong, a bamboo staff with a chakri attached at one end.
An Aerobie is a flying ring used in a manner similar to a chakram or flying disc (Frisbee), for recreational catches between two or more individuals. Its ring shape of only about 3 mm (0.12 in) thickness makes the Aerobie lighter and more stable in flight than a disc. It can be bent to tune it for straighter flight. Since it has very low drag and good stability, it can be thrown much farther than a flying disc. The Aerobie was used to set two former world records for thrown objects.
Chuck Hoberman is an artist, engineer, architect, and inventor of folding toys and structures, most notably the Hoberman sphere.
Paul B. MacCready Jr. was an American aeronautical engineer. He was the founder of AeroVironment and the designer of the human-powered aircraft that won the first Kremer prize. He devoted his life to developing more efficient transportation vehicles that could "do more with less".
Palo Alto Airport is a general aviation airport in the city of Palo Alto in Santa Clara County, California, United States, near the south end of San Francisco Bay on the western shore.
Walter Frederick Morrison was an American inventor and entrepreneur, who invented the Frisbee.
Aldo Weber Vieira da Rosa was a professor emeritus of electrical engineering at Stanford University. His research interests were in ionospheric processes, energy processes and renewable energy. He is the author of "Fundamentals of Renewable Energy Processes" and "Fundamentals of Electronics". He is also the holder of a US patent on the process for the production of ammonia.
The AeroPress is a manual coffeemaker invented by Alan Adler, founder of AeroPress, Inc. It consists of a cylindrical chamber, and a plunger with an airtight silicone seal, similar to a syringe. Ground coffee beans and water are steeped inside, then forced through a filter at the bottom of the chamber by pressing the plunger down through the chamber. It is capable of brewing highly concentrated coffee, which the manufacturer describes as "espresso style", but can also be used to brew filter strength coffee, or cold brew coffee.
Gregory Fenton Buckingham was an American competition swimmer, Olympic silver medalist, and former world record-holder in two events.
Russell Harrison Varian and Sigurd Fergus Varian were American brothers who founded one of the earliest high-tech companies in Silicon Valley. Born to theosophist parents who helped lead the utopian community of Halcyon, California, they grew up in a home with multiple creative influences. The brothers showed an early interest in electricity, and after independently establishing careers in electronics and aviation they came together to invent the klystron, which became a critical component of radar, telecommunications and other microwave technologies.
Mark Robert Showalter is a senior research scientist at the SETI Institute. He is the discoverer of six moons and three planetary rings. He is the Principal Investigator of NASA's Planetary Data System Rings Node, a co-investigator on the Cassini–Huygens mission to Saturn, and works closely with the New Horizons mission to Pluto.
Gordon B. Greb was an emeritus professor of San Jose State University, a "distinguished broadcast educator"' historian and an investigative journalist.
This is the history of Stanford University.
Ed Headrick, also known as "Steady" Ed Headrick, was an American toy inventor. Headrick served in combat in the army in WWII and was a deep-sea welder. He is most well known as the father of both the modern-day Frisbee and of the sport and game of disc golf.
