Joseph Tykociński-Tykociner
Joseph Tykociński-Tykociner (also known as Joseph T. Tykociner; 5 October 1877, in Włocławek, Congress Poland – 11 June 1969, in Urbana, Illinois, United States) was a Polish engineer and a pioneer of sound-on-film technology. In 1921 he became the first research professor of engineering at the University of Illinois at Urbana-Champaign. Within a year of his arrival at the university, he conducted the first sound-on-film motion picture recordings at a physics demonstration that showed how pictures and sound could be synchronized to produce a "talkie", a motion picture with sound. Life Tykociner was born into a Jewish family in Włocławek, a town in Congress Poland, Polish territory then under Russian control. Moone, Tom, "Joseph Tykociner: Pioneer of sound on film" Ingenuity.

List Of Multiple Discoveries
Historians and sociologists have remarked the occurrence, in science, of " multiple independent discovery". Robert K. Merton defined such "multiples" as instances in which similar discoveries are made by scientists working independently of each other. "Sometimes", writes Merton, "the discoveries are simultaneous or almost so; sometimes a scientist will make a new discovery which, unknown to him, somebody else has made years before." Commonly cited examples of multiple independent discovery are the 17th-century independent formulation of calculus by Isaac Newton and Gottfried Wilhelm Leibniz; the 18th-century discovery of oxygen by Carl Wilhelm Scheele, Joseph Priestley, Antoine Lavoisier and others; and the theory of the evolution of species, independently advanced in the 19th century by Charles Darwin and Alfred Russel Wallace. Multiple independent discovery, however, is not limited to such famous historic instances. Merton believed that it is multiple discoveries, rather th ...

Freeman John Dyson (15 December 1923 – 28 February 2020) was a British-American theoretical physics, theoretical physicist and mathematician known for his works in quantum field theory, astrophysics, random matrix, random matrices, mathematical formulation of quantum mechanics, condensed matter physics, nuclear physics, and nuclear engineering, engineering. He was professor emeritus in the Institute for Advanced Study in Princeton, New Jersey, Princeton and a member of the board of sponsors of the ''Bulletin of the Atomic Scientists''. Dyson originated several concepts that bear his name, such as Dyson's transform, a fundamental technique in additive number theory, which he developed as part of his proof of Mann's theorem; the Dyson tree, a hypothetical genetic engineering, genetically engineered plant capable of growing in a comet; the Dyson series, a Perturbation theory (quantum mechanics), perturbative series where each term is represented by Feynman diagrams; the Dys ...

Leon Cooper
Leon N. Cooper (né Kupchik; February 28, 1930 – October 23, 2024) was an American theoretical physicist and neuroscientist. He won the Nobel Prize in Physics for his work on superconductivity. Cooper developed the concept of Cooper pairs and collaborated with John Bardeen and John Robert Schrieffer to develop the BCS theory of conventional superconductivity. In neuroscience, Cooper co-developed the BCM theory of synaptic plasticity. Biography Childhood and education Leon N. Kupchick was born in the Bronx, New York City on February 28, 1930. His middle initial N. does not stand for anything, though some sources erroneously suggested his middle name was Neil. His father Irving Kupchik was from Belarus and moved to the United States after the Russian Revolution in 1917. His mother Anna (née Zola) Kupchik was from Poland; she died when Leon was seven. His father later changed the family's surname from Kupchick to Cooper when he remarried. Leon attended the Bronx High S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dennis Gabor
Dennis Gabor ( ; ; 5 June 1900 – 9 February 1979) was a Hungarian-British physicist who received the Nobel Prize in Physics in 1971 for his invention of holography. He obtained British citizenship in 1946 and spent most of his life in England. Life and career Gabor was born as Günszberg Dénes, into a Jewish family in Budapest, Austria-Hungary. In 1900, his family converted to Lutheranism. Dennis was the first-born son of Günszberg Bernát and Jakobovits Adél. Despite having a religious background, religion played a minor role in his later life and he considered himself agnostic. In 1902, the family received permission to change their surname from Günszberg to Gábor. He served with the Hungarian artillery in northern Italy during World War I. He began his studies in engineering at the Budapest University of Technology and Economics in 1918, later in Germany, at the ''Technische Hochschule Charlottenburg'' in Berlin, now known as Technische Universität Berlin.

Zeteticism
Marcello Truzzi (September 6, 1935 – February 2, 2003) was an American sociologist and academic who was professor of sociology at New College of Florida and later at Eastern Michigan University, founding co-chairman of the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), a founder of the Society for Scientific Exploration, and director for the Center for Scientific Anomalies Research. Truzzi was an investigator of various protosciences and pseudosciences and, as fellow CSICOP cofounder Paul Kurtz dubbed him "the skeptic's skeptic". He is credited with originating the oft-used phrase "Extraordinary claims require extraordinary proof", though earlier versions existed. Early life and education Truzzi was born in Copenhagen, Denmark, and was the only child of juggler Massimiliano Truzzi and his wife Sonya. His family moved to the United States in 1940 where his father performed with the Ringling Bros. and Barnum & Bailey Circus. Truzzi earned se ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Movietone Sound System
The Movietone sound system is an optical sound, optical sound-on-film method of recording sound for motion pictures, ensuring synchronization between sound and picture. It achieves this by recording the sound as a variable-density optical track on the same strip of film that records the pictures. The initial version of this system was capable of reproducing sounds up to 8500 Hz. Although modern sound films use variable-area tracks instead, modern motion picture theaters (excluding those that have transitioned to digital cinema) can play a Movietone film without modification to the projector (though if the projector's sound unit has been fitted with red LED or laser light sources, the reproduction quality from a variable density track will be significantly impaired). Movietone was one of four motion picture sound systems under development in the U.S. during the 1920s. The others were DeForest's Phonofilm, Warner Brothers' Vitaphone, and RCA Photophone. However, Phonofilm was p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
