Zu Chongzhi, a great mathematician in the Southern and Northern Dynasties, calculated pi to the seventh place after the decimal point. It is proved that pi is between 3. 14 15926 and 3. 14 15 127. It took more than a thousand years for Europeans to get the same result. Zu Chongzhi was a great mathematician in the Northern and Southern Dynasties. He calculated pi. Gauss is the son of an ordinary couple. His mother is the daughter of a poor stonemason. Clever as she is, she has no education and is almost illiterate. Before becoming Gauss's father's second wife, she was a maid. His father used to be a gardener, a foreman, an assistant to a businessman and an appraiser of a small insurance company. It has become an anecdote that Gauss was able to correct his father's debt account when he was three years old. He once said that he learned to calculate on Macon's pile of things. Being able to perform complex calculations in his mind is a gift from God for his life.

Gauss worked out the tasks assigned by primary school teachers in a short time: the sum of natural numbers from 1 to 100. His method is: sum 50 pairs of sequences with the structure of sum 10 1 to (1+ 100, 2+99, 3+98 ...), and get the result: 5050. This year, Gauss was 9 years old.

When Gauss 12 years old, he began to doubt the basic proof in element geometry. When he was 16 years old, it was predicted that a completely different geometry would inevitably be produced outside Euclidean geometry. He derived the general form of binomial theorem, successfully applied it to infinite series and developed the theory of mathematical analysis.

Gauss's teacher Brutner and his assistant Martin bartels realized Gauss's unusual talent in mathematics very early, and Herzog Karl willem ferdinand von Brunswick also left a deep impression on this gifted child. Therefore, since Gauss 14 years old, they have sponsored his study and life. This also enabled Gauss to study at Carolyn College (the predecessor of Brunswick College today) in 1792- 1795. /kloc-At the age of 0/8, Gauss transferred to the University of G? ttingen. At the age of 19, he was the first to successfully construct a positive 17 angle with a ruler.

Gauss married Miss johanna Elizabeth Lin Xiawei Osthoff from Brunswick in 1805 (1780- 1809). On August 2nd1806, Yue Se, the first child in his life, was born. Since then, he has had two more children. Wilhelmin (1809- 1840) and Louis (1809- 18 10). 1807, Gauss became a professor at the University of G? ttingen and director of the local observatory.
