Names Of Famous Mathematicions
• 3.
• Archimedes was a great mathematician of ancient times. His greatest contributions were in geometry. Archimedes made many contributions to geometry His methods started the idea for calculus which was &quot;invented&quot; 2,000 years later by Sir Isaac Newton and Gottfried Wilhelm von Leibniz.
Archimedes

• Aryabhatta was born in 476A.D in Kusumpur, India. He was the first person to say that Earth is spherical and it revolves around the sun. He gave the formula (a + b)2 = a2 + b2 + 2ab.He taught the method of solving the following problems.
Aryabhatta
• 5.
• He was born in a village of Mysore district. He was the first to give that any number divided by 0 gives infinity[00]. He has written a lot about zero, surds, permutation and combination. He wrote, “The hundredth part of the circumference of a circle seems to be straight. Our earth is a big sphere and that’s why it appears to be flat.”
• 6.
• Brahma Gupta was born in 598 A.D. in Pakistan. He gave four methods of multiplication. He gave the following formula, used in G.P series a + ar + ar2 + ar3 +……….. + arn-1 = (arn-1) ÷ (r – 1). He gave the following formula :Area of a cyclic quadrilateral with side a, b, c, d= √(s -a) (s- b) (s -c) (s- d) where 2s = a + b + c + d Length of its diagonals =
Bhramagupta
• 7.
• Blaise Pascal was born in Clermont in France, on 19th June 1623. His mother, Antoinette Begon, died when he was three; and his father, Etienne, who was a local judge with a scientific reputation, brought him up. Etienne had an unconventional view of education and decided to tutor his only son himself. At age 12, Blaise was curious about geometry When his father found out, Blaise was allowed to read his father’s mathematics books, because his father knew that he couldn’t stop his genius son anymore.
Blaise Pascal
• 8.
• Copernicus was born on February 19, 1473, in Thorn, Poland, to a family of merchants and municipal officials. Copernicus's maternal uncle, Bishop Lukasz Watzenrode, saw to it that his nephew obtained a solid education at the best universities. Before he left, his uncle had appointed him as a church administrator in Frauenberg. In January 1497, Copernicus began to study canon law at the University of Bologna. Copernicus's geographical and astronomical interests were greatly stimulated by Domenico Maria, an early critic of the accuracy of the Geography of the 2nd-century astronomer Ptolemy.
Copernicus Nicolaus
• 9.
• Euclid is one of the most influential and best read mathematician of all time. He is known as the father of geometry and is considered one of the great Greek mathematicians. It is believed that he was educated at Plato's academy in Athens and stayed there until he was invited by Ptolemy to teach at his newly founded university in Alexandria. Euclid founded the school of mathematics
Euclid
• 10.
• Galileo Galilei was born on February 15, 1564 in Pisa, Italy. Galileo pioneered &quot;experimental scientific method,&quot; and was the first to use a refracting telescope to make important astronomical discoveries.
Galileo
• 11.
• Gauss life was very simple. He received a stipend from the duke of Brunswick. Before his 25th birthday, he was already famous for his work in mathematics. When he became 30 he went to Gottingen to become director of the observatory. Gauss personal life was tragic and complicated.
Gauss
• 12.
• Isaac Newton (1642-1727) is perhaps the most famous Lucasian Professor of Mathematics. He is probably best known to the average person because of the story of the falling apple and its relationship to the discovery of gravity. Newton discovered the force of gravity and today the search is for its carrier: gravity waves. The years in between are a fascinating scientific story, detailed in a book edited by the current Lucasian professor, Stephen Hawking, Three Hundred Years of Gravitation.
Isaac Newton
• 13.
• Leonardo da Vinci is well known as a master of Florentine painter of the Renaissance. He was born and raised in Vinci, a Tuscan mountain town, in 1452. The son of a wealthy notary, he was given the best education that Florence could provide. He had a profound and insatiable love of knowledge and research which proved to be the controlling factor in his life.
Leonardo Da Vinci

• Pythagoras is the most interesting person in the history of mathematics. He was probably born between the 50th and 52nd Olympiads. He spent much of his time not only in Egypt but also in Babylonia. He returned to Samos to find a school there but was unsuccessful.
Pythagoras
• 15.
• Ramanujan was born on 22nd of December 1887 in a small village of Tanjore district, Madras. He showed that any big number can be written as sum of not more than four prime numbers. He also showed that how to divide the number into two or more squares or cubes. In the third century B.C. Archimedes noted that the ratio of circumference of a circle to its diameter is constant.
Ramanujan

• Thales, the acknowledged founder of Greek mathematics and philosophy, was also an astronomer. He was born at about 640 B.C. at Miletus. During his middle life, he was a statesman and eventually became a mathematician, astronomer and philosopher. He is said to have traveled quite extensively to such places including Crete, Egypt and Asia.
Thales

• Shakuntala Devi was born in 1939. In 1980, she gave the product of two, thirteen digit numbers within 28 seconds, many countries have invited her to demonstrate her extraordinary talent.
