The stepped reckoner or Leibniz calculator was a mechanical calculator invented by the German mathematician Gottfried Wilhelm Leibniz (started in 1673, when he presented a wooden model to the Royal Society of London [2] and completed in 1694). [1]
This project is focused on increasing coverage of primary works and links to open source material created or authored by Gottfried Wilhelm Leibniz. The ultimate end goal is to enable human readable and computer-accessible / machine-accessible versions of Leibniz's works. The project aims to facilitate access to Leibniz's thinking and concepts.
Gottfried Wilhelm Leibniz (or Leibnitz; [a] 1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who is credited, alongside Sir Isaac Newton, with the creation of calculus in addition to many other branches of mathematics, such as binary arithmetic and statistics.
The following outline is provided as an overview of and topical guide to Gottfried Wilhelm Leibniz: Gottfried Wilhelm (von) Leibniz (1 July 1646 [O.S. 21 June] – 14 November 1716); German polymath, philosopher logician, mathematician. [1] Developed differential and integral calculus at about the same time and independently of Isaac Newton.
Leibniz constructed just such a machine for mathematical calculations, which was also called a "stepped reckoner". As a computing machine, the ideal calculus ratiocinator would perform Leibniz's integral and differential calculus. In this way the meaning of the word, "ratiocinator" is clarified and can be understood as a mechanical instrument ...
Gottfried Wilhelm Leibniz (1646–1716) developed logic in a binary number system and has been called the "founder of computer science". [ 19 ] In 1702, Gottfried Wilhelm Leibniz developed logic in a formal, mathematical sense with his writings on the binary numeral system.
FIZ Karlsruhe — Leibniz Institute for Information Infrastructure, formerly Fachinformationszentrum Karlsruhe, is a not-for-profit company with the public mission to make sci-tech information from all over the world publicly available and to provide related services in order to support the national and international transfer of knowledge and the promotion of innovation.
The binary number system was refined by Gottfried Wilhelm Leibniz (published in 1705) and he also established that by using the binary system, the principles of arithmetic and logic could be joined. Digital logic as we know it was the brain-child of George Boole in the mid 19th century.
