# Topic: Mark I Calculator

###### In the News (Mon 24 Jun 19)

 Harvard Mark I - Wikipedia, the free encyclopedia The Mark I was followed by the Harvard Mark II (1947 or 1948), Mark III/ADEC (September 1949), and Harvard Mark IV (1952) – all the work of Aiken. The Mark III used some electronic components and the Mark IV was all-electronic, using solid-state components. The Mark I was eventually disassembled, although portions of it remain at Harvard in the Cabot Science Center. en.wikipedia.org /wiki/Harvard_Mark_I   (611 words)

 Grace Hopper - Wikipedia, the free encyclopedia She was the first programmer for the Mark I Calculator and the developer of the first compiler for a computer programming language. She graduated Phi Beta Kappa from Vassar College with a bachelor's degree in mathematics and physics in 1928 and pursued her graduate education at Yale University, where she received an MA degree in the same two subjects in 1930 and in 1934 became the first woman to receive a Ph.D. in mathematics. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were "debugging" the system. en.wikipedia.org /wiki/Grace_Hopper   (1091 words)

 Lens Angle of View & Field of View Lens Calculator // sweeting.org Use this lens calculator to view the lens angle of view and the field of view of a lens. The lens calculator draws from a database containing most of the lenses currently being made by the likes of Canon, Nikon and Sigma, as well as a generic catalogue of popular lens focal lengths. As the different sensors have slightly different aspect ratios, the "35mm equivalent lens" is calculated using the diagonal measurement of the current sensor against that of 35mm film. www.sweeting.org /mark/lenses   (755 words)

 CLA Calculator - good for Backglider design   (Site not responding. Last check: 2007-10-21) The second set of fins is helpful for calculating rockets with front fins, as they are used for boosters in multistage applications. I am wondering if, and how, I could use the calculator to calculate the CLA with rockets with (a) circulair fin(s) behind the body of the rocket. Again thanks a lot for using your CLA calculator and to my opinion our water rocket colleagues could use your CLA calculator to calculate CLA for "tubular" fins as well. waterrocket.uh-lab.de /cla_calculator.htm   (592 words)

 looking.back -- August Aiken conceived the plans for a large scale calculator in 1937 and sought a sponsor and partner to implement his ideas as a machine to assist Harvard University researchers in their computational undertakings. He initially approached Monroe Calculator Company but they could not see their way to assist him and subsequently he modified the proposal to be more plausible to IBM -- a company whose major product was the card processor. Mark I and Mark II were electromagnetic, using relays but Mark III and Mark IV had a variety of electronic components including vacuum tubes and solid-state transistors. ei.cs.vt.edu /~history/50th/August.html   (1683 words)

 The Science Bookstore - Books   (Site not responding. Last check: 2007-10-21) Starting with the Mark I in 1944, Aiken spearheaded an effort that provided not only the physical means of computation but also the tools to direct them and the people to operate them. The Harvard Mark III Calculator had the potential to be a significant entry into the field of computing, but events slowed its completion until competitors finished other markedly superior systems. The Mark III was not a machine that would be emulated or replicated beyond its lifetime, but the people who planned it, built it, programmed it, and operated it went on to make significant contributions to the science and practice of computing. www.thesciencebookstore.com /bookmain.asp?bookcat=Technology   (1491 words)
