Liebnitz wrote the description of a new calculating machine in 1668. I am a long-time user of Pascal, and its successor Modula-2, which was then superseded by Oberon. The Step Reckoner expanded on the French mathematician-philosopher Blaise Pascal's ideas and did multiplication by repeated addition and shifting. It was invented by French philosopher and mathematician Blaise Pascal. Origin: The Pascal was named after mathematician-physicist Blaise Pascal. In 1675 during the demonstration of the machine to the French Academy of Sciences, one of the scientists noticed that "...using the machine of Leibniz even a boy can perform the most complicate calculations!" Step Reckoner, a calculating machine designed (1671) and built (1673) by the German mathematician-philosopher Gottfried Wilhelm von Leibniz. Instead, the Step Reckoner represented numbers in decimal form, as positions on 10-position dials. His stepped reckoner was capable of adding, subtracting, multiplying, dividing, and extracting square roots through a series of stepped additions. Common references: Pascal is approximately the weight of a dollar bill lying flat on a surface. He presented a wooden model to the Royal Society of London on 1 February 1673 and received much encouragement.

His unique, drum-shaped gears formed the basis of many successful calculator designs for the next 275 years, an unbroken record for a single underlying calculator mechanism. He improved Pascal's invention to develop this machine. Fig. This meant that on could represent true, off could represent false, and the flow of current would directly represent the flow of logic. He then devised a competing design, the Stepped Reckoner which was meant to perform additions. Leibniz was a strong advocate of the binary system. 100 Pascals is the approximate pressure of a strong breeze. In 1673, Leibniz built the first true four-function calculator. Liebnitz stepped reckoner. Stepped Reckoner. The name Pascal was approvd by the General Conference on Weights and Measures in 1971. Only one survives today. A very simple program is shown below: Program Lesson1_Program1; Begin Write('Hello World. He concentrated on expanding Pascal's mechanism so it could multiply and divide. It was developed by a German mathematician-philosopher Gottfried Wilhelm Leibnitz in 1673. Gottfried Wilhelm Leibniz was a prominent German philosopher and mathematician. It was also used in the Curta calculator, a very popular portable calculator introduced in the second part of the 20th century. The Stepped Reckoner was not only suitable for multiplication and division, but also much easier to operate. Su aportación en este campo fue la conocida Stepped Reckoner , primera máquina que permitió allá por 1672 , realizar operaciones de adición, sustracción, multiplicación y división, sentando las bases para la primera calculadora mecánica comercializada 150 años después. Gottfried Wilhelm Leibniz built a machine called the stepped reckoner based on the design of the stepped drum in 1694. 1673 - Gottfried Wilhelm von Leibniz (1646-1716) Gottfried Wilhelm von Leibniz invented differential and integral calculus independently of Sir Isaac Newton, who is usually given sole credit. 1801 Invented by Joseph Jacquard Invents loom that is programmed using punched cards Machine gave fear of job replacements It was also supposed to calculate square roots.

When computers became electronic, the binary system was particularly appropriate because an electrical circuit is either on or off. The Pascal programming language was named in his honor. Nvidia has shipped some briefcases to selected media (no we have not received one just yet). The Step Reckoner expanded on the French mathematician-philosopher Blaise Pascal’s ideas and did multiplication by repeated addition and shifting. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's work as the supervisor of taxes in Rouen. It was made famous by Thomas de Colmar when he used it, a century and a half later, in his Arithmometer, the first mass-produced calculating machine. Blaise Pascal (1623-1662), ... "Stepped Reckoner", full-featured calculator, ("Leibniz wheel" for multiplication) Jacquard Loom (1801) inventor • Used punch cards to define complex patterns • Patterns woven into textiles • Punch cards were later used to code computer programs Leibniz was prescient in seeing the appropriateness of the binary system in calculating machines, but his machine did not use it. The stepped reckoner had a problem in the carry mechanism after more than two consecutive carries, and the other devices had carry mechanisms (one tooth wheel) that were limited in their capacity to carry across multiple digits or had no carry mechanism in between the digits of the accumulator. Whereas earlier calculating machines, such as Blaise Pascal’s Pascaline in France and Gottfried Wilhelm von Leibniz’s Step Reckoner in Germany, were mere curiosities, with the Industrial Revolution came a widespread need to perform repetitive operations efficiently. ... Blaise Pascal’s Pacaline, was the second mechanical calculator.
