The first mechanical calculator appeared in 1642, the creation of French intellectual and mathematics whizz kid Blaise Pascal as "a device that will eventually perform all four arithmetic operations without relying on human intelligence."
In 1921, Edith Clarke invented the "Clarke calculator", a simple graph-based calculator for solving line equations involving hyperbolic functions. This allowed electrical engineers to simplify calculations for inductance and capacitance in power transmission lines .
The genesis of calculators can be traced back to the early 17th century, a period marked by a surge in scientific inquiry and innovation. This era, often regarded as part of the Scientific Revolution, witnessed numerous inventions and discoveries that reshaped human understanding of the world.
Calculator, machine for automatically performing arithmetical operations and certain mathematical functions. Modern calculators are descendants of a digital arithmetic machine devised by Blaise Pascal in 1642. Later in the 17th century, Gottfried Wilhelm Leibniz created a more-advanced machine,
In 1632, the circular and rectangular slide rule was invented by W. Oughtred (1574-1660). Resembling a standard ruler, these devices allowed users to multiply, divide, and calculate roots and logarithms.
Invented in 1820 by French mathematician Charles Xavier Thomas de Colmar, the arithmometer was the first practical and affordable mechanical calculator. It could perform all four basic arithmetic operations and was much easier to use than the Pascaline.
A Brief History: The arithmometer was the first commercially successful calculating machine to complete all four basic operations — addition, subtraction, multiplication and division — according to IBM. Like Hahn, Thomas also based his calculator on the stepped drum mechanism of Leibniz.
The “ calculating clock ” was developed by German astronomer Wilhelm Schickard and first described in detail to his colleague Johannes Kepler in a 1623 letter. The letter reveals that the prototype and original machine were built, but tragically destroyed in a fire.
French inventor Blaise Pascal (June 19, 1623–Aug. 19, 1662) was one of the most reputed mathematicians and physicists of his time. He is credited with inventing an early calculator, amazingly advanced for its time, called the Pascaline. Fast Facts: Blaise Pascal.
Pascaline, the first calculator or adding machine to be produced in any quantity and actually used. The Pascaline was designed and built by the French mathematician-philosopher Blaise Pascal between 1642 and 1644. It could only do addition and subtraction, with numbers being entered by manipulating.
