In 1642, while still a teenager, he stairted some pioneerin wark on calculatin machines. Efter three years o effort an 50 prototeeps,[1] he biggit 20 feenisht machines (cawed Pascal's calculators an later Pascalines) ower the follaein 10 years,[2] foondit him as ane o the first twa inventors o the mechanical calculator.[3][4]

Pascal wis an important mathematician, helpin creaut twa major new auries o resairch: he wrote a signeeficant treatise on the subject o projective geometry at the age o 16, an later correspondit wi Pierre de Fermat on probability theory, strangly influencin the development o modren economics an social science. Follaein Galileo Galilei an Torricelli, in 1647, he rebuttit Aristotle's follaers that insistit that naitur abhors a vacuum. Pascal's results caused mony disputes afore bein acceptit.

In 1646, he an his sister Jacqueline identifeed wi the releegious muivement within Catholicism kent bi its detractors as Jansenism.[5] Follaein a releegious experience in late 1654, he begoud writin influential warks on filosofie an theology. His twa maist famous warks date frae this period: the Lettres provinciales an the Pensées, the umwhile set in the conflict atween Jansenists an Jesuits. In that year, he wrat an important treatise aboot the arithmetical triangle an aw. Atween 1658 an 1659, he wrote aboot the cycloid an its uise in calculatin the vollum o solits.

Ootthrou his life, Pascal wis in fail halth, espeicially efter the age o 18; he dee'd juist twa month efter his 39t birthday.[6]
