HERE ARE THE GREAT MATHEMATICIANS OF THE ERA.

MATHS IS LOVE AND LOVE IS POWER

1.)** PYTHAGORAS**

He belonged to Samos. A mathematician from Greece he is recognized as one of the pioneers in his field. Alive in the 570 –t95 BC, he is also credited to have been the founder of Pythagorean Cult that have been recorded as one of the initial groups who were involved in the studying and advancing Mathematics. He is supposed to have come up with the Pythagorean Theorem in trigonometry. There is a little bit of confusion about this with some opposing views, but we cannot deny his huge contributions to elemental mathematics. This theorem is very actively used in modern calculations towards the building of modern equipment. (* GREAT MATHEMATICIANS OF THE ERA.)*

2.) ANDREW WILES

The only mathematician on the list given here who is still alive. He is credited with the proving of Fermat’s Last Theorem which says that no positive integers a,b and c can satisfy the equation a^n+b^n=c^n For n greater then 2. (If n=2 it is the Pythagoras Formula). We cannot truly say that is role in mathematics is as large as the others on this list but he can be credited with “inventing” huge chunks of new mathematics for proving this theorem. His devotion warrants some credit as he literally locked himself away for 7 years to come up with a solution.

3.) **Isaac Newton and Wilhelm Leibniz:**

These two have been paired off because the two of together have been credited with being the founder of modern infinitesimal calculus. Their contribution is considered monumental in the area. Leibniz has been credited with having brought in modern standard notation especially the integral sign. His input to the field of topology are invaluable. Isaac Newton was a genius who due to the grand scientific epic principia gathered notable credit as the man who actually invented calculus. Both men have given significant inputs to their field in their own way.

4.)**Leonardo Pisano Bigollo**:

Also called Leonardo Fibonacci was a great mathematician to come out of the middle ages. Alive from 1170 to 1250, he most famous for having brought in the notorious Fibonacci series the world on the western side. This series was known to Indian mathematicians since the 200 BC, but still one cannot discount the importance of this sequence that often appeared in biological systems.

5.)**Alan Turing:**

He is a Cryptanalyst and computer scientists who is acknowledged as one the best brains of the 20^{th} Century. worked during the Second World War in Government Code and Cypher School in Britain. They have made many important findings and revolutionary modes of breaking codes. These later on helped in analyzing the German Enigma Encryptions. With war coming to an end he started work on computing.

6.)**René Descartes:**

This physicist, mathematician and philosopher of French descent is most famous for his ‘Cogito Ergo Sum’ philosophy. Apart from this Frenchman made many vital and inventive contributions of Mathematics. He aided in establishing the ground for modern calculus along with Leibniz and Newton. Apart from this his development of Cartesian Geometry may be better known to readers. More familiar as the standard graph, this changed the way distances were measured and expressed.

7.)**Euclid**:

In 300 BC this man who is known to be the father of Geometry. Not much has been documented about his life back then and most of information we can gather is put together posthumously. His magnum Opus – Elements is still considered an important book and was used in teaching till the 20^{th} century. He was recognized for the teaching of precise, sound testimony for theorems and suppositions. Beside, his Elements were five other existing works, that have been assumed to be also usually on the subject of Geometry or Number theory.

8.)**G. F. Bernhard Riemann:**

Son of an impoverished family, born in the year 1826, this man became a known mathematician in the 19^{th} century. His contributions include a wide range of theorems that have his name. His work was to a large extent ignored for 50 years after they made their appearance, mainly because there were few mathematicians who could comprehend his work.

9.)**Carl Friedrich Gauss:**

Known to be a genius even as a child he made is first discovery in his teens and penned the unbelievable Disquisitiones Arithmeticae, his magnum opus, before he reached 21. Numerous people were aware of Gauss’s exceptional intellectual capability

10.)**Leonhard Euler**:

Born 1707 till his demise in 1783, he made many a contribution to his field, in fact he was considered the king of mathematics. He is considered the most important mathematician for his contributions. He was considered as path-breaking and next only to Einstein in genius. His main contribution to the field is with the introduction of mathematical notation counting the idea of a function, shorthand trigonometric functions, the ‘e’ for the base of the natural logarithm (The Euler Constant),
