248 years ago today, April 30, 1777 (March 23, 1777 in the lunar calendar), was the birthday of the German mathematician Gauss. Among the famous mathematicians in ancient and modern times, it is probably extremely rare to have a high degree of mathematical talent like Gauss since childhood. Gauss was born on April 30, 1777 into a peasant family in Germany. He has loved mathematics since he was a child. It is said that when he was less than three years old, one day, he watched his father do the calculations. After the calculation was over, his father read out the money number and was about to write it down. A small voice came from beside him: "Dad, the calculation was wrong. The total should be..." The father was surprised. He recalculated the results and found that the child's answer was correct. When Gauss was in elementary school, the teacher once had a problem and asked them to start with 1, add 2, add 3, add 4,... all the way to 100, thinking that this would definitely confuse the students. Unexpectedly, Gauss figured it out in a short time. The teacher saw that the answer was 5050, which was exactly right and was surprised. Gauss calculated it like this: 1 and 100, 2 and 99, 3 and 98... The sum of each pair is 101, and there are 50 pairs of such numbers within 100, and 101×50=5050. His calculation method is algebraically called the arithmetic series summation formula. Gauss was only 10 years old at the time. Gauss became more and more interested in mathematics, and mathematical theorems, formulas and verification methods were discovered and confirmed one after another. At the age of 11, he discovered the expansion of (X Y)n. At the age of 17, he discovered the law of quadratic reciprocity in number theory. On March 30, 1796, Gauss, who was only 18 years old, made the most amazing discovery in the history of mathematics. He used algebraic methods to solve geometric problems for two thousand years, and found that only using a ruler and compasses to make a circle and inscribed a regular 17-sided shape is also called a 17-sided ruler compass drawing method. To commemorate this most important discovery made as a teenager, Gauss expressed the hope that a regular 17-sided shape would be engraved on his tombstone after his death. In 1799, Gauss proved another important theorem: any algebraic equation of one variable has a root. This result is mathematically called the "Basic Theorem of Algebra" and also known as the "Gauss Theorem". In 1801, Gauss published his Collection of Essays on Arithmetic. Gauss began to study astronomy at the age of 23 and solved the problem of measuring the elliptical orbit of stars, also known as the elliptical function. Gauss's achievements come from talent on the one hand and hard work on the other. His family was very poor. In winter, in order to save lamp oil, his father asked him to go to bed after dinner. Gauss made his own oil lamp and concentrated on reading until late into the night under the weak light. At the age of 15, he studied the mathematical works of famous mathematicians such as Newton, Euler, and Lagrange, and mastered the theory of calculus proficiently. Gauss's success did not fall from the sky, but was achieved through hard study. He values scientific research above all else. When his wife was seriously ill, Gauss was studying an esoteric mathematical problem. The servant came to him several times: "If you don't go over immediately, you won't be able to see her one last time!" Gauss said,"Tell her to wait until I get there." It wasn't until he finished his research that he didn't go to visit his wife. Gauss was like this. He was talented and more diligent and studious. He finally became a famous mathematician and was known as the "Prince of Mathematics". On the early morning of February 23, 1855, Gauss passed away in his sleep at the age of 78.
