The document discusses several famous mathematicians throughout history including: - Pythagoras of Samos, a Greek philosopher and founder of Pythagoreanism who believed that mathematics was the ultimate reality. - René Descartes, a French mathematician and philosopher who is considered the founder of analytic geometry and the Cartesian coordinate system. - Isaac Newton, an English physicist and mathematician who laid the foundations for classical mechanics with his laws of motion and universal gravitation.

14. An ancient Greek
mathematician, physicist, astronomer
and engineer. Although little is known of
his life, he is regarded as one of the
leading scientists in classical antiquity.
His early use of calculus included the first
known summation of an infinite series
with a method that is still used today. He
is also credited with designing innovative
machines, including weapons and the
screw pump that bears his name. He is
best known for allegedly exclaiming
"Eureka!" after discovering what is known
today as Archimedes' principle.

15. English mathematician, philosopher,
and mechanical engineer who
originated the idea of a programmable
computer. Parts of his uncompleted
mechanisms are on display in the
London Science Museum. In 1991 a
perfectly functioning difference
engine was constructed from
Babbage's original plans.

16. German mathematician and scientist
who contributed significantly to many
fields, including number
theory, statistics, analysis, differential
geometry, geodesy, electrostatics, astr
onomy, and optics.
Sometimes known as "the prince of
mathematicians" and "greatest
mathematician since antiquity", Gauss
had a remarkable influence in many
fields of mathematics and science and
is ranked as one of history's most
influential mathematicians.
Gauss was a child prodigy, of whom
there are many anecdotes pertaining
to his astounding precocity while a
mere toddler, and made his first
ground-breaking mathematical
discoveries while still a teenager.

17. English
physicist, mathematician, astronomer, nat
ural philosopher, and alchemist. His
treatise Philosophiae Naturalis Principia
Mathematica, published in
1687, described universal gravitation and
the three laws of motion, laying the
groundwork for classical
mechanics, which dominated the
scientific view of the physical universe for
the next three centuries and is the basis
for modern engineering.
Newton shares the credit with Gottfried
Leibniz for the development of the
calculus. He also demonstrated the
generalized binomial theorem, developed
the so-called "Newton's method" for
approximating the zeroes of a
function, and contributed to the study of
power series.

18. French mathematician, physicist, and
religious philosopher.
He was a child prodigy who was
educated by his father.
The work done by Fermat and Pascal
into the calculus of probabilities laid
important groundwork for Leibniz's
formulation of the infinitesimal calculus
Following a mystical experience in late
1654, he abandoned his scientific work
and devoted himself to philosophy and
theology. His two most famous works
date from this period: the Lettres
provinciales and the Pensées. Pascal
suffered from ill health throughout his
life and died two months after his 39th
birthday.

19. Pythagoras of Samos was an Ionian
(Greek) philosopher and founder of the
religious movement called
Pythagoreanism. He is often revered as a
great mathematician, mystic and
scientist; however some have
questioned the scope of his
contributions to mathematics or natural
philosophy.
We do know that Pythagoras and his
students believed that everything was
related to mathematics and that
numbers were the ultimate reality
and, through mathematics, everything
could be predicted and measured in
rhythmic patterns or cycles. The
Pythagoreans were musicians as well as
mathematicians. Pythagoras wanted to
improve the music of his day, which he
believed was not harmonious enough
and was too hectic.
