9 lip 2019 · 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.
Accuracy was the foundation of his work. He made his design drawings on metal plates to prevent distortion. Burroughs filed his first patent for the invention of a "calculating machine" in 1885. It was designed to ease the monotony of clerical arithmetic.
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, and, especially in the late 19th century, inventors produced calculating machines that were smaller and smaller and less and less laborious to use. In the ...
