Euclid (pron.: /?ju?kl?d/ EWK-lid; Ancient Greek: ????????? Eukleid?s), fl. 300 BC, also known as Euclid of Alexandria, was a Greek mathematician, often referred to as the "Father of Geometry". He was active in Alexandria during the reign of Ptolemy I (323–283 BC). His Elements is one of the most influential works in the history of mathematics, serving as the main textbook for teaching mathematics (especially geometry) from the time of its publication until the late 19th or early 20th century.[1][2][3] In the Elements, Euclid deduced the principles of what is now called Euclidean geometry from a small set of axioms. Euclid also wrote works on perspective, conic sections, spherical geometry, number theory and rigor.
Srinivasa Ramanujan FRS (
pronunciation (help·info)) (22 December 1887 – 26 April 1920) was an Indian mathematician and autodidact who, with almost no formal training in pure mathematics, made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions.
Living in India with no access to the larger mathematical community,
which was centered in Europe at the time, Ramanujan developed his own
mathematical research in isolation. As a result, he sometimes
rediscovered known theorems in addition to producing new work. Ramanujan
was said to be a natural genius by the English mathematician G. H. Hardy, in the same league as mathematicians such as Euler and Gauss.[1] He died at the age of 32.
Aristotle (Ancient Greek: ???????????, Aristotél?s) (384 BC – 322 BC)[1] was a Greek philosopher and polymath, a student of Plato and teacher of Alexander the Great. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, linguistics, politics, government, ethics, biology, and zoology. Together with Plato and Socrates (Plato's teacher), Aristotle is one of the most important founding figures in Western philosophy. Aristotle's writings were the first to create a comprehensive system of Western philosophy, encompassing morality, aesthetics, logic, science, politics, and metaphysics.
Plato (pron.: /?ple?to?/; Greek: ??????, Plát?n, "broad";[2] 424/423 BC[a] – 348/347 BC) was a Classical Greek philosopher, mathematician, student of Socrates, writer of philosophical dialogues, and founder of the Academy in Athens, the first institution of higher learning in the Western world. Along with his mentor, Socrates, and his student, Aristotle, Plato helped to lay the foundations of Western philosophy and science.[3] In the words of A. N. Whitehead
Sania Mirza (Telugu: ?????? ??????, Hindi: ?????? ???????, S?niy? Mirz?; born 15 November 1986, in Bombay) is a professional Indian tennis player, well known for her powerful forehand ground strokes. She is the current Indian No.1 in both singles and doubles and has held this position since 2003. In her career, Mirza has notable wins over Svetlana Kuznetsova, Vera Zvonareva, Marion Bartoli; former World No. 1s Martina Hingis & Dinara Safina; and current World No. 1 Victoria Azarenka.

Saina was also the first Indian to win a Super Series tournament, by clinching the Indonesia Open with a victory over higher-ranked Chinese Wang Lin in Jakarta on 21 June 2009. Saina is supported by the Olympic Gold Quest.[6]
Albert Einstein (pron.: /?ælb?rt ?a?nsta?n/; German: [?alb?t ?a?n?ta?n] (
listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics[2][3] and the most influential physicist of the 20th century. While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"),[4] he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".[5] The latter was pivotal in establishing quantum theory.
