Blaise Pascal: the story on HearLore

Mechanical Calculators And Inventions

In 1642 Blaise constructed a mechanical calculator called the Pascaline to help his father with tax calculations. He was not yet nineteen years old when he built this device capable of addition and subtraction. Eight examples of these machines survive today with four held by the Musée des Arts et Métiers in Paris. One more example resides in the Zwinger museum in Dresden Germany. Despite being pioneering forerunners to modern computer engineering the machine failed commercially. It remained expensive and cumbersome to use in practice. Pascal presented one such machine to Christina Queen of Sweden in 1632. He continued improving the design over the next decade building approximately twenty finished machines. His work also extended to fluid dynamics where he invented the hydraulic press. He clarified concepts of pressure and vacuum by generalizing Evangelista Torricelli's earlier experiments. The SI unit for pressure bears his name today as does Pascal's law of hydrostatics.

When was Blaise Pascal born and where did he grow up?

Blaise Pascal was born on the 19th of June 1623 in Clermont-Ferrand, France. His family moved to Paris in 1631 when his father Étienne decided to teach him at home instead of sending him to school.

What inventions did Blaise Pascal create during his lifetime?

Blaise Pascal constructed a mechanical calculator called the Pascaline in 1642 to assist with tax calculations for his father. He also invented the hydraulic press and clarified concepts of pressure and vacuum through fluid dynamics research.

How did Blaise Pascal contribute to the development of probability theory?

Blaise Pascal developed mathematical theory of probability through correspondence with Pierre de Fermat starting in 1654. Their collaboration examined fair division of stakes in gambling problems which established the notion of expected value used in modern economics.

What religious experiences influenced Blaise Pascal's later writings?

On the 23rd of November 1654 Blaise Pascal experienced an intense religious vision between ten-thirty and twelve-thirty at night. He recorded this event in a document known as the Memorial which he sewed into his coat until after his death.

When did Blaise Pascal die and what caused his illness?

Blaise Pascal died on the 18th of August 1662 following convulsions that led to extreme unction in a Paris hospital. Autopsy results showed grave stomach organ issues and brain damage though speculation suggests tuberculosis or stomach cancer combination affected him throughout life.
