The world's first electronic digital computer, the Atanasoff–Berry computer, was built on the Iowa State campus from 1939 through 1942 by John V. Atanasoff, a professor of physics and mathematics, and Clifford Berry, an engineering graduate student. In 1941, Konrad Zuse developed the world's first functional program-controlled computer, the Z3.
Claude Elwood Shannon (April 30, 1916 – February 24, 2001) was an American mathematician, electrical engineer, computer scientist and cryptographer known as the "father of information theory " and as the "father of the Information Age ". [1] [2] Shannon was the first to describe the Boolean gates (electronic circuits) that are essential to ...
Eccles, William and Jordan, Frank Wilfred. Patented the Eccles–Jordan trigger circuit, [23] the so-called "bistable flip-flop ", a building block of all digital memory cells. Built from vacuum tubes, their concept was essential for the success of the Colossus codebreaking computer . 1943, 1951.
1963 – Edward Lorenz discovers the butterfly effect on a computer, attracting interest in chaos theory. [54] 1961 – Using computational investigations of the 3-body problem, Michael Minovitch formulates the gravity assist method. [55] [56] 1964 – Molecular dynamics invented independently by Aneesur Rahman.
Grace Murray Hopper: a pioneer of computing. She worked alongside Howard H. Aiken on IBM's Mark I. Hopper and also came up with the term " debugging ." Hedy Lamarr: invented a "frequency hopping" technology that the Navy used during World War II to control torpedoes via radio signals.
Charles Babbage. Charles Babbage KH FRS ( / ˈbæbɪdʒ /; 26 December 1791 – 18 October 1871) was an English polymath. [1] A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer. [2] Babbage is considered by some to be "father of the computer".
Analog of the Japanese Type B Cipher Machine (codenamed Purple) built by the U.S. Army Signal Intelligence Service Purple analog in use. In the history of cryptography, the "System 97 Typewriter for European Characters" (九七式欧文印字機 kyūnana-shiki ōbun injiki) or "Type B Cipher Machine", codenamed Purple by the United States, was an encryption machine used by the Japanese Foreign ...
Computer science. Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software ).
