Rudolf, a German mathematician in the 16th century, spent his whole life calculating pi to 35 decimal places. Later generations called it Rudolf's number. After his death, others engraved this number on his On the tombstone. The Swiss mathematician Jacques Bernoulli studied spirals (known as the thread of life) during his lifetime. After his death, a logarithmic spiral was engraved on his tombstone, and the inscription also read: "Although I Changed, but still the same.” This is a pun that both depicts the nature of the spiral and symbolizes his love for mathematics.
Von Neumann, one of the most outstanding mathematicians of the 20th century. As we all know, the electronic computer invented in 1946 has greatly promoted the progress of science and technology and social life. In view of the key role von Neumann played in the invention of electronic computers, he was hailed by Westerners as the "Father of Computers". From 1911 to 1921, von Neumann was studying at the Lutheran High School in Budapest. , he stood out and was highly valued by his teachers. Under the individual guidance of Mr. Fecht and in cooperation with him, von Neumann published his first mathematical paper when he was less than 18 years old.
Galois was born in a small town not far from Paris. , his father was a school principal and also served as mayor for many years. The influence of his family made Galois move forward courageously and fearlessly. In 1823, the 12-year-old Galois left his parents to study in Paris. Unsatisfied with the rigid classroom indoctrination, he went to study the most difficult original mathematics books on his own, and some teachers also gave him great help. Teachers commented on him that "it is only suitable to work in the cutting-edge fields of mathematics."
Archimedes was born in 287 BC in Syracuse, Sicily, at the southern tip of the Italian peninsula. His father is a mathematician and astronomer. Archimedes had a good family upbringing since he was a child. At the age of 11, he was sent to Alexandria, the cultural center of Greece at that time, to study. In this famous city known as the "City of Wisdom", Archimedes read widely and absorbed a lot of knowledge. He also became a disciple of Euclid's students Eratoses and Canon, and studied "Elements of Geometry" .
Zu Chongzhi’s outstanding achievement in mathematics was the calculation of pi. Before the Qin and Han Dynasties, people used "three days per day" as the pi rate, which was the "ancient pi rate". Later, it was discovered that the error of the ancient rate was too large. The pi should be "one diameter of a circle and three days more than three days." However, there are different opinions on how much there is. It was not until the Three Kingdoms period that Liu Hui proposed a scientific method for calculating pi - "circle cutting", which uses the circumference of a regular polygon inscribed in a circle to approximate the circumference of a circle. Liu Hui calculated that the circle is inscribed in 96 polygons and obtained π=3.14. He also pointed out that the more sides the inscribed regular polygon has, the more accurate the π value obtained. Based on the achievements of his predecessors, Zu Chongzhi worked hard and calculated repeatedly, and found that π is between 3.1415926 and 3.1415927. And the approximate value of π in the form of a fraction is obtained, which is taken as the approximate ratio and taken as the density. Taking six decimal places is 3.141929, which is the fraction closest to the value of π within 1000 in the numerator and denominator. It is currently impossible to investigate exactly what method Zu Chongzhi used to arrive at this result. If he were to calculate according to Liu Hui's "circle cutting" method, he would have to calculate that the circle is inscribed with 16,384 polygons. How much time and tremendous labor this would take! This shows that his tenacious perseverance and intelligence in scholarship are admirable. It was more than a thousand years later that foreign mathematicians obtained the same density calculated by Zu Chongzhi. In order to commemorate Zu Chongzhi's outstanding contribution, some foreign mathematics historians suggested calling π= "Zu rate".
Sales was born in 624 BC and was the first world-famous mathematician in ancient Greece. He was originally a very shrewd businessman. After accumulating considerable wealth by selling olive oil, Salles concentrated on scientific research and travel. He is diligent and studious, but at the same time he is not superstitious about the ancients. He has the courage to explore, create and think actively about problems. His hometown is not too far from Egypt, so he often travels to Egypt. There, Salles became acquainted with the vast mathematical knowledge that the ancient Egyptians had accumulated over thousands of years. When he traveled to Egypt, he used an ingenious method to calculate the height of the pyramid, which made the ancient Egyptian King Amesses envious.
