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, France. [2]
Blaise Pascal [a] (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, philosopher, and Catholic writer. Pascal was a child prodigy who was educated by his father, a tax collector in Rouen .
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]
Leibniz got the idea for a calculating machine in 1672 in Paris, from a pedometer. Later he learned about Blaise Pascal's machine when he read Pascal's Pensées. He concentrated on expanding Pascal's mechanism so it could multiply and divide. He presented a wooden model to the Royal Society of London on 1 February 1673 and received much ...
French polymath Blaise Pascal invented the mechanical calculator. [23] Called machine arithmétique , Pascal's calculator and eventually Pascaline , its public introduction in 1645 started the development of mechanical calculators first in Europe and then in the rest of the world.
Pascal’s conversion experience, with its distinctly Mosaic overtones, would eventually lead him to show that Christianity’s firmest foundation is the sanctity of Judaism, both past and present.
The two machines were essentially different in that Pascal's machine was designed primarily for addition and (with the use of complementary numbers) for subtraction. The adding machine in Schickard's design may have jammed in the unusual case of a carry being required across too many dials, but it could smoothly subtract by reversing the motion ...
Blaise Pascal and Wilhelm Schickard were the two original inventors of the mechanical calculator in 1642. [1] For Pascal, this was an adding machine that could perform additions and subtractions directly and multiplication and divisions by repetitions, while Schickard's machine, invented several decades earlier, was less functionally efficient ...
