Pascaline (also known as the arithmetic machine or Pascal's calculator) is a mechanical calculator invented by Blaise Pascal in 1642. 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 . [ 2 ]
An early Pascaline on display at the Musée des Arts et Métiers, Paris In 1642, in an effort to ease his father's endless, exhausting calculations, and recalculations, of taxes owed and paid (into which work the young Pascal had been recruited), Pascal, not yet 19, constructed a mechanical calculator capable of addition and subtraction, called ...
The 17th century marked the beginning of the history of mechanical calculators, as it saw the invention of its first machines, including Pascal's calculator, in 1642. [4] [16] Blaise Pascal had invented a machine which he presented as being able to perform computations that were previously thought to be only humanly possible. [17]
Pascaline, 1642 – Blaise Pascal's arithmetic machine primarily intended as an adding machine which could add and subtract two numbers directly, as well as multiply and divide by repetition. Stepped Reckoner, 1672 – Gottfried Wilhelm Leibniz's mechanical calculator that could add, subtract, multiply, and divide.
1642: Mechanical calculator. The Pascaline is built by Blaise Pascal. [390] 1643: Barometer: invented by Evangelista Torricelli, or possibly up to three years earlier by Gasparo Berti. [391] 1650: Vacuum pump: Invented by Otto von Guericke. [392] 1656: Pendulum clock: Invented by Christiaan Huygens.
The history of computing hardware spans the developments from early devices used for simple calculations to today's complex computers, encompassing advancements in both analog and digital technology. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic ...
Its production debut of 1851 [2] launched the mechanical calculator industry [4] which ultimately built millions of machines well into the 1970s. For forty years, from 1851 to 1890, [7] the arithmometer was the only type of mechanical calculator in commercial production, and it was sold all over the world. During the later part of that period ...
It was the first calculator that could perform all four basic arithmetic operations. [ 3 ] Its intricate precision gearwork, however, was somewhat beyond the fabrication technology of the time; mechanical problems, in addition to a design flaw in the carry mechanism, prevented the machines from working reliably.
