John Presper Eckert
John Adam Presper "Pres" Eckert Jr. (April 9, 1919 – June 3, 1995) was an American electrical engineering, electrical engineer and computer pioneer. With John Mauchly, he designed the first general-purpose electronic digital computer (ENIAC), presented the first course in computing topics (the Moore School Lectures), founded the Eckert–Mauchly Computer Corporation, and designed the first commercial computer in the U.S., the UNIVAC I, UNIVAC, which incorporated Eckert's invention of the mercury delay-line memory. Education Eckert was born in Philadelphia to Ethel M. Hallowell, who came from an old Philadelphia Quakers, Quaker family, and John Eckert, a wealthy real estate developer of Swiss German people, Swiss German and Alsace, Alsatian descent. He was raised in a large house in Philadelphia's Germantown, Philadelphia, Germantown section. During elementary school, he was driven by chauffeur to William Penn Charter School, and in high school joined the Engineer's Club of Phil ...

Eckert–Mauchly Computer Corporation
The Eckert–Mauchly Computer Corporation (EMCC) (March 1946 – 1950) was a computer company founded by J. Presper Eckert and John Mauchly. It was incorporated on December 22, 1947. After building the ENIAC at the University of Pennsylvania, Eckert and Mauchly formed EMCC to build new computer designs for commercial and military applications. The company was initially called the Electronic Control Company, changing its name to Eckert–Mauchly Computer Corporation when it was incorporated. In 1950, the company was sold to Remington Rand, which later merged with Sperry Corporation to become Sperry Rand, and survives today as Unisys. Founding Before founding Eckert–Mauchly Computer Corporation, Mauchly researched the computing needs of potential clients. Over a period of six months in 1944 he prepared memos and kept detailed notes of his conversations. For instance, Mauchly met with United States Census Bureau official William Madow to discuss the computing equip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Analyzer
The differential analyser is a mechanical analogue computer designed to solve differential equations by integration, using wheel-and-disc mechanisms to perform the integration. It was one of the first advanced computing devices to be used operationally. In addition to the integrator devices, the machine used an epicyclic differential mechanism to perform addition or subtraction - similar to that used on a front-wheel drive car, where the speed of the two output shafts (driving the wheels) may differ but the speeds add up to the speed of the input shaft. Multiplication/division by integer values was achieved by simple gear ratios; multiplication by fractional values was achieved by means of a multiplier table, where a human operator would have to keep a stylus tracking the slope of a bar. A variant of this human-operated table was used to implement other functions such as polynomials. History Research on solutions for differential equations using mechanical devices, discou ...

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] |
Moore School Of Electrical Engineering
The Moore School of Electrical Engineering was a school at the University of Pennsylvania. The school was integrated into the University of Pennsylvania School of Engineering and Applied Science. The Moore School came into existence as a result of an endowment from Alfred Fitler Moore on June 4, 1923. It was granted to Penn's School of Electrical Engineering, located in the Towne Building. The first dean of the Moore School was Harold Pender. The Moore School is particularly famed as the birthplace of the computer industry: * It was here that the first general-purpose Turing complete digital electronic computer, the ENIAC, was built between 1943 and 1946. * Preliminary design work on the ENIAC's successor machine the EDVAC resulted in the stored program concept used in all computers today, the logical design having been promulgated in John von Neumann's ''First Draft of a Report on the EDVAC'', a set of notes synthesized from meetings he attended at the Moore School. * The ...

Wharton School Of The University Of Pennsylvania
The Wharton School ( ) is the business school of the University of Pennsylvania, a private Ivy League research university in Philadelphia. Established in 1881 through a donation from Joseph Wharton, a co-founder of Bethlehem Steel, the Wharton School is the world's oldest collegiate business school. It is one of six Ivy League Business Schools, and is the business school which has produced the highest number of billionaires in America and the 45th and 47th U.S. president Donald Trump. The Wharton School awards undergraduate and graduate degrees with a school-specific economics major (academic), major and concentrations in over 18 disciplines in Wharton's academic departments. The undergraduate degree is a general business degree focused on core business skills. At the graduate level, the Master of Business Administration program can be pursued by itself or along with dual studies leading to a joint degree from its law, engineering, and government schools.

Philo Farnsworth
Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971), "The father of television", was the American inventor and pioneer who was granted the first patent for the television by the United States Government. Burns, R. W. (1998), ''Television: An international history of the formative years''. IET History of Technology Series, 22. LondonThe Institution of Engineering and Technology (IET) p. 370. . He also invented a video camera tube, and the image dissector. He commercially produced and sold a fully functioning television system, complete with receiver and camera—which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana. In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth Fusor, employing inertial electrostatic confinement (IEC). Like many fusion devices, it was not a practical device for generating nuclear power, although it provides a viable source of neutrons. The desi ...
