2: Blaise Pascal (1623-1662) Blaise Pascal was born in Clermont-Ferrad and spent most of his childhood there. His mother died during his infancy and he had to live with his father, Etienne, and his sisters. | He did not go to school but was instead taught by his father. After a while he and his family moved to Paris. His father did not want him to learn certain math items until he was old enough. But even though his father did not teach him about math and such he learned it on his own.
3: At the age of 12 he was studying geometry and other math problems that people over twice his age were working on! As he went through life he made the following contributions, Here we tell about of them and other some interesting facts.
5: The Pascaline In 1642, at the age of eighteen Blaise Pascal invented his numerical wheel calculator called the Pascaline to help his father a French tax collector count taxes. The Pascaline had eight movable dials that added up to eight figured long sums and used base ten. When the first dial (one's column) moved ten notches - the second dial moved one notch to represent the ten's column reading of 10 - and when the ten dial moved ten notches the third dial (hundred's column) moved one notch to represent one hundred and so on.
6: Roulette Machine Blaise Pascal introduced a very primitive version of the roulette machine in the 17th century. The roulette was a by-product of Blaise Pascal's attempts to invent a uninterrupted motion machine.
8: Pascal Triangle Even though Blaise Pascal was not the first person to work on the Pascal triangle - the Chinese and Islamic mathematicians used it more than 500 years before, his Treatise on the Arithmetical Triangle in 1653 was famous for being the first extensive study of it. It is clear from the above table that any number in the above table is equal to the sum of the numbers above it and on its left - with the exception of the first row and the first column where every number is one. | Pascal Triangle Even though Blaise Pascal was not the first person to work on the Pascal triangle - the Chinese and Islamic mathematicians used it more than 500 years before, his Treatise on the Arithmetical Triangle in 1653 was famous for being the first extensive study of it.

10: Thoughts (1670) Written during the last years of Pascal's life, this collection of short essays and sayings were the working notes for a work of Christian apologetics which aimed to use psychology and history. They provide the fullest account of Pascal's religious thought - man's weakness and hopelessness without God, his hatred of boredom and enslavement to meaningless distraction, man's glory with God and the authority of the Bible, prophecy, and faith.
12: Pascal (Pa) Unit of atmospheric pressure named in honor of Blaise Pascal, whose experiments greatly increased knowledge of the atmosphere. A pascal is the force of one newton acting on a surface area of one square meter. It is the unit of pressure designated by the International System. l00,OOO Pa= 1000mb 1 bar
14: Wrist Watch The first reported person to actually wear a watch on the wrist was the French mathematician and philosopher, Blaise Pascal. With a piece of string, he attached his pocket watch to his wrist.
15: Pascal Blaise Pascal's contribution to computing was recognized by computer scientist Nicklaus Wirth, who in 1972 named his new computer language Pascal (and insisted that it be spelled Pascal, not PASCAL).
