**The Early Years**

Blaise Pascal was born June 19, 1623 in Clermont. His mother died when he was only three years old, so his father packed up Blaise and his three sisters and headed off to Paris. Even as a child, Pascal showed signs of great intellect. Unfortunately his father felt language was most important and thus Pascal was secluded from the world of math until he was twelve. Blaise borrowed a math book from a tutor and started reading up on some basic geometry. One day while secretly studying at play time, he proved the sum of all angles in a triangle adds to 180°. He cut the three corners off the triangle and put them together to form a straight line, or 180° angle. His father, extremely impressed, found this proof lying on the floor of Pascal’s room so he decided to let him pursue his math studies further.

**Life Work**

At sixteen, Pascal was attending weekly meetings with his father and other French mathematicians. In this year he presented a sheet full projective geometry theorems, included in this was Pascal’s hexagon. From 1642-1644 he invested himself in inventing the first digital calculating machine. In 1646 Pascal converted to Jansenism, a Roman Catholic religion. Blaise’s further studies in geometry, hydrodynamics, and hydrostatic and atmospheric pressure helped him to invent the hydraulic press and the syringe. He also came up with the arithmetic triangle, which anyone in a mathematical field has investigated at some point in their life.

(a + b)

^{10}= 1a

^{10}b

^{0}+ 10 a

^{9}b

^{1}+45 a

^{8}b

^{2}+120 a

^{7}b

^{3}+ 210 a

^{6}b

^{4}+252 a

^{5}b

^{5}+210 a

^{4}b

^{6}+120 a

^{3}b

^{7}+ 45 a

^{2}b

^{8}+10 a

^{1}b

^{9}+1 a

^{0}b

^{10}

If you want to expand (a + b)^{10}, for example, go to the 11th row down (first row is labelled as 0). The terms of the expansion will all be of the form a*x*b*y* where *x*+*y*=10 and *x* and *y* are whole numbers between 0 and 10.Another use for this is that it gives you the number of different ways you can choose some of a collection of objects. If you have 10 objects and you want to choose 3 of them, go to the 10th row (start counting at 0) and the 3rd position in, again starting to count at 0 and you see that there are 120 different ways to choose 3 items from a collection of 10.

**The Latter years**

He died in Paris on August 19, 1662 at the age of thirty-nine. All the stress he had put on himself by constantly studying took a great toll on his body and contributed to his death. He also suffered from insomnia and acute dyspepsia from the age of seventeen or eighteen which also lead to his demise.

I found your biography very interesting, and very educational.

But I would like to know what acute dyspepsia is. I really have no Idea.

ReplyOptionsGreat Job Mr. McDonald! I envy you. Your biography was jam-packed full of

very vluable and interesting information. By reading this biography on Blaise

Pascal I feel like a more wholesome and knowledgable person. Thank you for

changing my life in such a dramatically positive way.

ReplyOptionswow micheal you must have spent hours on this haha……it must have been a couple weekends ago when you said no i can't come out tonight im gonna stay in and do my math homework so Mr Laxon will give me a good mark…..he did a good job didnt he eh?
