Oath of the Peach Garden

Percy Sinclair Pilcher (16 January 1866 – 2 October 1899) was a British inventor and pioneer aviator who was his country's foremost experimenter in unpowered flight at the end of the nineteenth century.
David Edward Hughes (16 May 1831 – 22 January 1900), was a British-American inventor, practical experimenter, and professor of music known for his work on the printing telegraph and the microphone.
 He is generally considered to have been born in London but his family moved around that time so he may have been born in Corwen, Wales.
 His family moved to the U.S. while he was a child and he became a professor of music in Kentucky.
 In 1855 he patented a printing telegraph.
 He moved back to London in 1857 and further pursued experimentation and invention, coming up with an improved carbon microphone in 1878.
 In 1879 he identified what seemed to be a new phenomenon during his experiments: sparking in one device could be heard in a separate portable microphone apparatus he had set up.
 It was most probably radio transmissions but this was nine years before electromagnetic radiation was a proven concept and Hughes was convinced by others that his discovery was simply electromagnetic induction.
Georges-Joseph Ranque (7 February 1898 – 15 January 1973) was the inventor of the Ranque-Hilsch vortex tube, which generates streams of hot and cold gas from a stream of compressed gas.
The Vortex football originated in 1993 by Oddzon Toys under license from toy inventor David Führer as a blue football with a black extension branching off three fins for aerodynamic efficiency.
 The vortex is usually used in primary school instead of a javelin.
 The shape and weight of the ball enabled long distance throws not possible with an ordinary football.
 When the vortex is thrown the whistles on the side whistle so it sounds cooler.
 Oddzon was ultimately acquired by Hasbro Corporation and the product now sells under the Nerf brand, owned by Hasbro.
Charles Grafton Page (in Salem, Massachusetts January 25, 1812 – May 5, 1868 in Washington, D.C.) was an American electrical experimenter and inventor, physician, patent examiner, patent advocate, and professor of chemistry.
Coke Stevenson Reed is an American mathematician and inventor from Austin, Texas.
 He is the inventor of the Data Vortex Supercomputer which uses a network topology and switch logic based on his and Krystyna Kuperberg's solution to a problem posed by Stan Ulam in the Scottish Book.
The Vortex Garden is a privately owned public garden in the Hessian city of Darmstadt (Germany).
 It is a pantheistic permaculture garden at the art nouveau area of Mathildenhoehe and alludes to Viktor Schauberger’s discovery of “levitational force” through artistic depictions by internationally renowned sculptors including John Wilkes, Jacopo Foggini, Jerome Abel Seguin and Hyesung Hyun.
 The garden is the private property of Henry Nold of Darmstadt, but is open to the public.
David Fuhrer is an award winning American inventor and entrepreneur.
 David Fuhrer has licensed more than 300 toys, games and household products including products such as Aqua Doodle and the Nerf Vortex Football.
 Brand Week Magazine (February 2009) refers to Fuhrer as "one of the more successful rainmakers in the toy industry".
Viktor Schauberger (30 June 1885 in Holzschlag, Upper Austria – 25 September 1958 in Linz, Austria) was an Austrian forest caretaker, naturalist, pseudoscientistref>Ronald Engert: "Die Forellenturbine als Prinzip der kostenlosen Energiegewinnung.

The Oath of the Peach Garden is a fictional event in the historical novel "Romance of the Three Kingdoms" by Luo Guanzhong.
 This event is set at the end of the Eastern Han dynasty around the time of the Yellow Turban Rebellion in the 180s CE.
 Liu Bei, Guan Yu and Zhang Fei took an oath of fraternity in a ceremony in the Peach Garden (believed to be in present-day Zhuozhou, Hebei), and became sworn brothers from then on.
 Their goal in taking the oath was to protect the Han Empire from the Yellow Turban rebels.
 The oath bound the three men, who would later play important roles in the establishment of the state of Shu Han during the Three Kingdoms period.
 It is also often alluded to as a symbol of fraternal loyalty.
