Mathematician, physicist, religious philosopher and writer, Blaise Pascal was born in Clermont- Ferrand France, in June 19, 1623 and died aged 39 in Paris in August 19, 1662.

As a child he was tutored by his father, who first avoided teaching mathematics to Pascal for fear that it might overstrain his young mind. But Pascal was curious to know what geometry was all about and taught it to himself.

Blaise Pascal did not attend school but learned classics from his father. He began to study geometry at the age of 12 when he discovered a theorem on his own.

He proved to be a math prodigy and at the age of 16 discovered one of the basic theorems of projective geometry. At 18 he invented the first mechanical adding machine. Some of the principles used in its making are still used in mechanical calculators. Five years later he published an essay on mathematics that was highly regarded in the academic community and praised by Descartes.

Working with his friend Pierre-Simon de Fermat, Pascal formulated the modern theory of probability and combinatorial analysis. Their probability theory arose from an attempt to deal mathematically with a gambling problem. While working on this, Pascal investigated and wrote extensively on a number system that we now call Pascal‘s triangle.

Pascal's triangle is a ready reference for finding the odds governing combinations.  each number within the triangle is obtained by adding the two numbers immediately above it.

Pascal triangle is a triangular array of numbers that dates back to ancient China. Over the centuries mathematicians have discovered in this triangle many different number patterns related to situations in arithmetic, algebra, geometry and other branches of mathematics. It is frequently used to determine probabilities and to solve problems involving permutations and combinations.

He is regarded as the founder of the Theory of Probability. He also invented the first digital calculator to assist his mathematician father in local administration.

Studies in geometry, hydrodynamics, hydrostatics and atmospheric pressure led him to invent the syringe and the hydraulic press.

Pascal’s principle also called Pascal’s Law states that in a stationary fluid in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container.

In his "Essai Pour Les Coniques" written in 1640, he stated his "mystic hexagram" theorem:

"If a hexagram be inscribed in a conic, then the points of intersection of the three pairsnof opposite sides are collinear and the converse applies".

Blaise Pascal ‘provincial letters’ composed after he quit science for theology are examples of beautiful French prose.
