Ship Latching Hold On-off



First computer
Generally speaking, the "world-recognized first electronic digital computer" is considered by most people to be the "ENIAC" born in 1946. It is mainly used to calculate ballistics. It is manufactured at the Moore Electric College of Pennsylvania State University, but it is huge. It consists of 17,468 tubes, 60,000 resistors, 10,000 capacitors and 6,000 switches. It covers an area of more than 170 square meters. It weighs about 30 tons and consumes nearly 150 kilowatts of electricity. Obviously, such a computer is costly and inconvenient to use. This statement was widely adopted in computer basic textbooks. In fact, in 1973, according to the US Supreme Court's ruling, the earliest electronic digital computer should be John Atanasov, an associate professor of physics at Iowa State University, and his graduate student. Assistant "ABC" (ABC) manufactured by Clifford E. Berry (1918-1963) in October 1939. The reason for this misunderstanding is that one of the "ENIAC" research groups, Mokley, plagiarized John Atanasov's research in 1941 and applied for a patent in 1946. For various reasons, this error was reversed until 1973. (For details, see Baidu Encyclopedia - "John Athanasiv" entry, I hope everyone will remember ABC and John Attanathov, I hope that future textbooks can modify this error).
Later, in recognition and commemoration of John Athanasov’s great contribution in the field of computers, in 1990 the former US President George Herbert Walker Bush awarded John Attanathov the highest technology award in the United States - National Science and Technology Awards." (On October 19, 1973, a local court in Minnesota, USA, after 135 trials, publicly pronounced: "Mozzily and Eckert did not invent the first computer, but took advantage of the ideas in Atanasov's invention. "And the judgment of Mozzily and Eckert's patent is invalid, on the grounds that Atanasov told Mozelli his initial idea of the computer as early as 1941. But Atanasov's Iowa The university did not apply for a patent for ABC computers, and the lawsuit was not a few computer designers, but two computer companies, Honeywell and Sperry Rand.)
