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]
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 Pascal's calculator or the Pascaline.
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]
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 ...
View through the back of Pascal's calculator. Pascal invented his machine in 1642. In 1642, while still a teenager, Blaise Pascal started some pioneering work on calculating machines and after three years of effort and 50 prototypes [18] he invented a mechanical calculator. [19] [20] He built twenty of these machines (called Pascal's calculator ...
19-year-old Blaise Pascal begins to develop the Pascaline, the first practical mechanical calculator, initially to help with the recording of taxes. [ 1 ] Exploration
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 Renaissance saw the invention of the mechanical calculator by Wilhelm Schickard in 1623, [9] and later by Blaise Pascal in 1642. [10] A device that was at times somewhat over-promoted as being able to perform all four arithmetic operations with minimal human intervention. [11]
