A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries, if not millennia, the history of vacuum tube computers is confined to the middle of the 20th century. Lee De Forest invented the triode in 1906. The ...
Elmer Tiling Cunningham (September 1, 1889 – June 14, 1965) was an American entrepreneur and businessman, specializing in vacuum tubes and radio manufacturing. He is best known for being the most successful business person to produce counterfeit (AKA bootleg) or unlicensed vacuum tubes (1915-1920).
The Geissler tube was used for entertainment throughout the 1800s and evolved around 1910 into commercial neon lighting. Advances in Plucker and Geissler's discharge tube technology developed into the Crookes tube , with which the electron was discovered in 1897, and in 1906 into the amplifying vacuum tube , the basis of electronics and long ...
The Great Gatsby is a 1925 novel by American writer F. Scott Fitzgerald.Set in the Jazz Age on Long Island, near New York City, the novel depicts first-person narrator Nick Carraway's interactions with Jay Gatsby, the mysterious millionaire with an obsession to reunite with his former lover, Daisy Buchanan.
Schematic symbol used in circuit diagrams for a vacuum tube, showing control grid. The control grid is an electrode used in amplifying thermionic valves (vacuum tubes) such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode (plate) electrode. The control grid usually consists of a cylindrical ...
Nick Carraway is a fictional character and narrator in F. Scott Fitzgerald's 1925 novel The Great Gatsby.The character is a Yale University alumnus from the American Midwest, a World War I veteran, and a newly arrived resident of West Egg on Long Island, near New York City.
The six-episode spin-off centers around “The Great Experiment,” a concept established by Princess Augusta (King George’s mother) and the House of Lords in the premiere episode.
One of the most significant consequences of Geissler tube technology was the discovery of the electron and the invention of electronic vacuum tubes. By the 1870s better vacuum pumps enabled scientists to evacuate Geissler tubes to a higher vacuum; these were called Crookes tubes after William Crookes. When current was applied, it was found that ...
