Grade 11 Math Essay - Blaise Pascal
by Toni Lintunen
Blaise Pascal was born on June 19, 1623 in Clermont Ferrand. His
nationality was french. He died in 1662. He was credited for his
imaginative and subtle work in geometry and other branches of mathematics.
His work influenced later generations of theologians and philosophers,
helping make mathematics what it is today. Blaise Pascal is considered part
of the foundation of the very heart of mathematics.
At age 12 he mastered Euclid\'s Elements. In 1645, he invented and
sold the first adding machine. His study of hydrostatics led to the
invention of the syringe and hydraulic press. At age 16, he formulated the
basic theorems of projective geometry. These theorems became known as
Pascal\'s theorem. He proved that the level of mercury column in a
barometer is determined by the increase or decrease in the surrounding
atmospheric pressure. This discovery verified the hypothesis of the Italian
physicist Evangelista Torricelli, concerning the effect of atmospheric
pressure on the equilibrium of liquids.
After publishing Essay pour les coniques (Essay on conic sections),
Pascal temporarily abandoned the study of mathematics due to poor health.
He lived in Paris for a while in a frivolous manner as a break. His
interest in probability theory of the odds in gambling games lead him to
discover the Theory of probability in conjunction with Pierre de Fermat.
This theory dealt with the actuarial, mathematical, social statistics, and
calculations used in today\'s modern theoretical physics. At the end of
1654, after several months of depression, Pascal had a life altering
religious experience. He entered the Jansenist monastery in Port Royal.
Here, he never published his own name again in his mathematical studies.
He wrote a pseudonym to help in the struggle against the Jesuits for the
defense of the Jansenist, Antoine Arnauld. In 1658, he broke with the
Jansenists, and left the monastery. Pascal died on August 19, 1662 from
cancer, at age 39. In his life, his most famous work was perhaps Pensees
(thoughts). This was a set of deeply personal meditations in a somewhat
fragmented form on human suffering and faith in God. Another famous work
of his was called "Pascal\'s Wager." This expressed the conviction that
belief in God is rational: If God does not exist, one stands to lose
nothing by believing in him anyway, whereas if he does exist, one stands to
lose everything by not believing.
Pascal\'s Gears were the first mechanical computing machine ever
invented. It was invented in 1642. This machine consisted of a series of
interlocking discs and gears, hence the name Pascal\'s Gears. Each gear had
one of the digits from 0 to 9 engraved on it. A complete turn of any gear
caused the gear to its left to make one-tenth of a turn, displaying the
next highest number. This mechanism was used in calculators and adding
machines up until the 1960\'s. The concept of Pascal\'s Gears is still being
used today in mechanical car odometers.
This was perhaps his most important piece of work he has ever done.
Written in 1653, it stated that in a fluid at rest, pressure on any surface
exerts a force perpendicular to the surface and independent of the
direction of orientation of the surface. The law is sometimes assumed to
include the principle that any additional pressure applied to a fluid will
be transmitted equally to every point in the fluid. This law is the basis
of machines involving hydraulic systems.
Pascal has proven to be a very unique individual in the time that he
had lived. He discovered very essential concepts of mathematics making it
the way it is today. At the same time, he dwelled in philosophical and
religious ideas and concepts. One common trend in both areas he studied,
is the use of logic. The use of logic, being the heart of mathematics, was
the basis of his philosophical and religious aspects of his life. These
parts of his life revolved around logic and order. Logic, what answered
his mathematical ponderings, also answered the questions he asked about
