Blaise Pascal's Calculator

Origin
Blaise Pascal was a child prodigy who began scientific and mathematical discoveries from an early age. While a teenager, he created one of the first mechanical calculators. His body of work included the study on fluids and pressure, geometry and probability and later on several religious essays. Pascal had poor health, especially after his 18th year, and his death came just two months after his 39th birthday.
