Title: Famous Mathematicians

Famous Mathematicians
2
Archimedes
3
Archimedes was an ancient Greek scholar born in
287 BC in Syracuse, SicilyDied 212 BC Syracuse,
Siily.
4
During the siege of Syracuse, Archimedes
designed siege machines (flame throwers), which
destroyed a substantial part of the army of the
5
Some historians say Archimedes as one of the
greatest mathematicians in history alongside
Newton, Gauss and Euler. His contributions were
in geometry, mechanics and even considered one of
the pioneers of mathematical analysis.
6
Until we reach his scientific contributions in
writing, mostly because of Eratosthenes, and Pope
Conon Dosifey.
7
Mathematics .. It a good approximation of
the number p (223/71 ltp lt22 / 7, 3,1428)
Calculate the surface of parabolic segment and
the volumes of different mathematical bodies.
Examine multiple curves and spirals, one of which
bears his name Archimedean spiral defines
polupravilni polyhedron, called Archimedes'
bodies. For proof perpetuality (top) of the
sequence of natural numbers (also known as the
axiom of Archimedes).
8
Archimedes was killed by a Roman soldier despite
orders from the Roman general Marcus Claudius
Marcellus not to touch. The spread of the Greeks
legend that Archimedes was cut off while writing
an equation on the sand, thus like to oppose his
elevation to the Roman inefficiency.

Isaac Newton
10
English scientist, was born on January 4, 1643 In
Ulstorp in Colsterworth, Great Britain. Lived in
England Profession mathematician, physicist,
astronomer, theologian worked at Cambridge
University, Cambridge University Alma Mater. A
discovery of mathematical analysis.
11
Working on problems of physics, Isaac Newton
opens a mathematical analysis that underlies the
development of science until today.

complicated formulas wanderbut most scientists

resolved Physics, he loves then called Newton

problems By comets traveling and visit the
planets Stars observed magnets deals but the
story remains and physics as it keywordeveryone

13
Leonhard Euler
14
Born April 15, 1707 In Basel, Switzerland.
Profession mathematician, physicist, astronomer
Worked in the Imperial Academy of Arts and
Sciences, Berlin Academy Alma Mater University of
Basel learn Manager Johann Bernoulli.
15
Already in his childhood shows great mathematical
talents, he wants his father to study theology.
In 1720 began his studies at Basel University -
Faculty of Philosophy primary ends, then at the
insistence of his father recorded in the
Theological Faculty, which never ends.
16
Swedish mathematician Leonhard Euler first test
squares in which each symbol appears only once in
each row and each column. He calls them the
"Latin", as used letters of the Latin alphabet in
their analysis. This type of squares are proving
useful in the design of scientific experiments
and are interesting as mathematical objects.
17
Euler is the author of major discoveries in
various fields of mathematics, the mathematical
analysis to graph theory. He first used a large
part of contemporary inscriptions, most notably
in the field of analysis, including the signs of
function 1 cosine, sine, tangent.
18
Euler in 1727 was invited to St. Petersburg for
the formation of the local Academy of Sciences.
Where he became professor of physics and
mathematics. But soon he began to develop a
successful shipbuilding, cartography, astronomy,
theory of rows and number theory. in 1735 largely
lost his vision, while monitoring the sun without
However, unfortunately, Euler continued his
research, relying on his incredible memory and
amazingly accurate calculations, which makes
mind. Euler was the first published systematic
manual elementary mechanics in 1736.
19
In 1733 in Petersburg, he married Katharina Gzel,
daughter of the director of the Academy of Arts.
They have thirteen children, of whom only survive
three sons and two daughters.
20
In 1741 Euler left for Berlin, and from 1744 to
1766 was director of the Math section of the
Berlin Academy. In 1759 he performed the post
of president, but receives no official post.
Euler in 1766 decided to return again in St.
Petersburg, where he remained until the end of
his life (18 September 1783). In 1910
published the first complete collected works of
Leonard Euler.

Remarkable constants in mathematics This
equality connects one of the most important
constants Neperovoto number imaginary unit
Ludolfovoto number, unit and zero. According to
the famous German mathematician Felix Klein and
teacher gender is one of the most interesting
relationships in mathematics in general. When it
follows the formula, discovered by the great
Leonhard Euler.
22
Leonhard Euler died on September 18, 1783 Saint
Petersburg Russia
23
Johann Carl Friedrich Gauss
24
Gauss was born on April 30, 1777 in Brunswick as
the only son of a poor family. When he was a
little boy he didnt with his exceptional
mathematical abilities. By 1791. Duke of
Brunswick bear the costs of his education. Next
in Göttingen from 1795 to 1798g. and ends in
Helmsted over 1799g. From 1807 until the end of
his days, is a director of the astronomical
observatory and professor at the University of
Göttingen.
25
Joachim Carl Friedrich Gauss died on February 23,
1855 in Goettingen, Germany

Algorithm Gauss-Newton
• Algorithm Gauss-Newton is a modification of
Newton's method, developed by Carl Friedrich
Gauss to solve the problems for nonlinear least
squares, which seeks a minimum of

parameter of p1, ..., pn and m n.

Algorithm Gauss-Newton iterative procedure,
which starts with a selected initial value of the
vector p - p0. Pk subsequent approximations are
obtained from where f (f1, ..., fm),
Jf (p) is the matrix of Jacob for f at point p

Mohammed al Horezmi
30
Mohammed al Horezmi is an Iranian mathematician,
astronomer and geographer. Born at the end of 8
Horezam century, died around 840. Often called
"father of algebra. Bear his name and today's
algorithms. Al Horezmi lives during the
management of the Abbasid Empire during the reign
of caliph Al Mamut, who he entrusts the
management of education. He also sent him on a
scientific expedition in Afghanistan today.
31
It is believed that Al Horezmi laid the
foundations of algebra and introduces the world
to Indian figures.
32
His book, algebra and equations is the first of
its kind. Currently, the manuscript of this book
is located in Oxford. After translation of the
book in Latin it became the basis for the
development of algebra in Europe.
