Modern times

First electric motor (1827) and first electrical generator (Ányos Jedlik). David Schwarz invented and designed the first flyable rigid airship (aluminium-made), later he sold his patent for German Graf Zeppelin. Ottó Bláthy, Miksa Déri and Károly Zipernowsky invented the transformer in 1885.[72][72] (Ottó Bláthy) invented the Turbogenerator and Wattmeter, Telephone exchange (Tivadar Puskás), Ford Model T and assembly line (therefore he is the inventor of industrial mass production) József Galamb, Tungsten electric bulb (1904) (Sándor Just) and the krypton electric bulb (Imre Bródy), weak equivalence principle and surface tension Loránd Eötvös, Electronic Television and camera-tube (1926) and Plasma TV (1936) (Kálmán Tihanyi), Vitamin C and the first artificial vitamin Albert Szent-Györgyi, mathematical tools to study fluid flow and mathematical background of supersonic flight and inventor of swept-back wings "father of Supersonic Flight" (Theodore Kármán), ramjet propulsion Albert Fonó, Turboprop propulsion by (György Jendrassik), (Leó Szilárd): nuclear chain reaction (therefore he was the first who realized the feasibility of an "atomic bomb". In August 1939, Szilard approached his old friend and collaborator Albert Einstein and convinced him to sign the Einstein–Szilárd letter, lending the weight of Einstein's fame to the proposal. The letter led directly to the establishment of research into nuclear fission by the U.S. government and ultimately to the creation of the Manhattan Project. Szilárd, with Enrico Fermi, patented the nuclear reactor). Other notable Hungarian inventions include holography (Dennis Gabor), the ballpoint pen (László Bíró), thermonuclear fusion and the theory of the hydrogen bomb (Edward Teller), and the BASIC programming language (John Kemeny, with Thomas E. Kurtz), Low level laser therapy or "light therapy" (Endre Mester), artificial blood (István Horváth), Rubik's cube (Ernő Rubik).
