## Carl Friedrich Gauss

Carl Friedrich Gauss (30.04.1777, Braunschweig) is well known German mathematician recognized for his discoveries in number theory, geometry, probability theory, geodesy, planetary astronomy, the theory of functions, and potential theory (including electromagnetism). His first discovery was on geometry by building up a 17-sided polygon in 1792, and later on, his most distinguished discovery is in fundamental algebra theorem: the number of real and complex roots of a polynomial depends on the degree of the polynomial. On sequences, he established the proof of his own theorem stating that the sum of

any sequence could be calculated from the formula . He proved the solution to Second-Degree Equation through his method of Contrast Rule. He also worked on Fourth-Degree Equations. His first published book is named as the foundation of Modern Number Theorem. Gauss was awarded the Copley Medal which is the most prestigious award given annually by the Royal Society of London regarding his discovery on electromagnetism.
