## Karl Gauss

**Johann Karl Friedrich Gauss** is perhaps the most famous of the mathematicians featured on these pages.

Born in 1777 in Germany, Gauss was a child prodigy. The most famous story is of a young schoolboy Gauss summing the integers
between 1 to 100 (answer=5050). Gauss's teacher had made his class complete the assignment to grade papers but Gauss was able to
add the numbers almost immediately. Gauss had found a way to add up an arithmetical series.
Later, when he was 19, Gauss was able to demonstrate how to construct a heptadecagon (17 sides) using only a straightedge and compass (Euclid's tools). By 19, Gauss could do what
Euclid and other geometer's had tried to do for a long time.

While working on his PhD in Gottingen, Gauss began to prove the fundamental theorem of Algebra. This theorem states that every polynomial has a root of the form **a + b***i*. Gauss was
able to prove that every number is the sum of at most three triangular numbers. Gauss then developed the algebra of congruences.

By 1801, Gauss had developed the "Least Squares Fitting" which is a procedure used to find the curve which best fits a group of points. Always afraid to publish his findings, Gauss did not publish his method and Adrien Legendre published first. Gauss employed his technique to
calculate the oribit of the asteroid, Ceres. Gauss also proved himself to be an ingenius mathematical physicist and engineer. He constructed the first telegraph with Wilhelm Weber.

Gauss was infact the man who arrived at the conclusions about Euclid's Fifth Postulate and could disprove for certain cases. However, Gauss's moto of *pauca sed matura*(Few but ripe) prevented him from publishing his works. Later he received credit for his genius.

Sadly, Gauss passed away in 1855 in his hometown of Braunschweig.
