What is Zu Chongzhi s great contribution? It feels like he s great.

Contribution to Mathematics.

Astronomy, calendar, engineering.

Zu Chongzhi, Zu Xuan, and Zu Hao are three generations of grandchildren, all of whom are mathematicians.

Zu Chongzhi of the Southern Dynasty was a famous mathematician and astronomer in ancient China. From an early age, he had a strong interest in scientific research, paying attention to learning from the achievements of his predecessors, but not blindly following them. Later, he made many achievements, most notably in the field of mathematics, where he obtained a more accurate measure of pi.

Zu Chongzhi's calculation of the time of one year, compared with the results measured by modern astronomical science, is only 50 seconds different; The "thousand-mile ship" he built traveled hundreds of miles a day; He designed and manufactured the water mill, which can lick rice and grind noodles at the same time.

Zu Chongzhi used and developed the "circumcision" created by his predecessors, and for the first time in the world, the value of pi was calculated to the seventh digit after the decimal point, that is, between and . This achievement is nearly a thousand years ahead of the world.

Set to a precise 7 decimal places.

Speaking of Zu Chongzhi, I don't know what everyone can think of him? Hearing the name of Zu Chongzhi, the first thing that comes to mind is mathematics, yes, Zu Chongzhi is an outstanding mathematician and astronomer in the Northern and Southern Dynasties, he has been studying natural science all his life, and his main contribution is also in mathematics, astronomical calendar and mechanical manufacturing, and his greatest contribution is that he calculated pi to the seventh decimal place for the first time on the basis of the precise method of exploring pi pioneered by Liu Hui, so he has made a significant contribution to mathematical research. Next, I will tell you more about him.

Zu Chongzhi has received a good family education since he was a child, his grandfather will tell him some knowledge of astronomy, his father led him to read the scriptures, so he was influenced by the family, his ears and eyes were touched, plus Zu Chongzhi, he was a hard-working person since he was a child, and he was curious about everything, so he had a particularly strong interest in natural science, literature and philosophy, especially astronomy, and he already had a reputation for erudition in his early years. He calculated that the true value of pi is between and is equivalent to a scientist who is accurate to the decimal point and calculates to the 7th decimal place. Zu Chongzhi's contribution has played a very big role not only in China, but also in the world.

In addition to pi, Zu Chongzhi also wrote five volumes of "Fixation", which was included in the famous "Ten Books of Calculation", in "Fixation", Zu Chongzhi put forward the problem of "opening the difference power" and "opening the difference", the specific solution of the difference power is to use the quadratic algebraic equation to solve the problem of positive heel, and the problem of opening the difference refers to the calculation method used to find the length of its side by opening the square, and Zu Chongzhi's solution is also a pioneering work. His "Fixation" has also spread to Korea and Japan, and it is mentioned in the bibliography of the ancient education system of Korea and Japan. In astronomy, Zu Chongzhi also observed and calculated the orbits of the five planets in the sky and the time required to orbit one week, and gave a more accurate five-star conjunction period, which is also a major contribution to astronomy.

So Zu Chongzhi has made significant contributions to all disciplines in our history, and he is a very great person. The above is only a personal opinion, if there is any error, please understand.

In addition to the astronomical calendar and mathematics, Zu Chongzhi also studied mechanics, he built compass cars and thousand-mile ships, in addition, he was also very proficient in music, he annotated many ancient books, and he also wrote ten volumes**, he was truly a versatile scientist. The most famous of his works on mathematics is the "Fixation", in addition to the "Nine Chapters of Arithmetic Translation", "Commentary on Double Differences", etc., but these have also been lost.

He was a mathematician and an astronomer, who devoted his life to the study of natural sciences, opened up pi to 7th place, and then wrote many excellent works, such as the Great Ming Calendar, in which particularly advanced legislation appeared and provided methods for astronomical research.

Calculated pi to 7 decimal places, promoted the development of the mathematical industry, and created the art of conjugation. The astronomical calendar was calculated, and some machine-building equipment was invented.

Zu Chongzhi (April 20, 429 A.D., 500 A.D.) was an outstanding mathematician and scientist in China, whose main contributions were mathematics, astronomical calendars and mechanics.

Zu Chongzhi, for the first time in the history of mathematics in the world, calculated the value of pi ( ) to six decimal places, that is, to. He proposed an approximate rate of 22 7 and a density rate of 355 113, which was the earliest in the world, 1100 years earlier than Europe, so some people advocate calling it the "ancestral rate", that is, the ancestor of pi.

He was not only an outstanding mathematician and astronomer, but also an outstanding mechanical expert. We have recreated a variety of ingenious machines such as the long-lost guide car, the thousand-mile ship, and the water mill.

He also cleared the source after many years of calculations, compiled a new calendar, "Da Ming Answer Simplified Calendar".It was the most advanced calendar in the world at the time.

Zu Chongzhi was the first to accurately reduce pi to the seventh decimal place.

Zu Chong studied natural sciences all his life, and his main contributions were mathematics, astronomical calendars, and mechanical engineering. On the basis of the precise method of exploring pi pioneered by Liu Hui, he actuarially calculated "pi" to the seventh decimal place for the first time.

That is, between and , the "ancestral rate" proposed by him has made a significant contribution to the study of mathematics. It wasn't until the 16th century that the Arab mathematician Al Qasi broke this record.

Zu Chongzhi's research on pi has positive practical significance, and his research adapts to the needs of production practice at that time. He personally studied weights and measures, and used the latest results of pi to correct the calculations of the volume of ancient measuring vessels.

In ancient times, there was a measuring instrument called "kettle", which was generally one foot deep, and the shape was a round brother and an old columnar, and Zu Chongzhi used his pi to study the world and find out the exact value.

He also recalculated the "Lijia Quantity" created by Liu Xin in the Han Dynasty, and corrected the value with the "ancestral rate". Later, when people made measuring instruments, they used Zu Chongzhi's "Zu Xian early rise rate" value.

Zu Chongzhi has been fond of mathematics since he was a child, and he learned a lot of mathematics under the guidance of his father and grandfather. Once, his father brought him a copy of the Sutra of Calculations from the bookshelf, which was a famous mathematics book from the Western Han Dynasty or earlier. It is said that the circumference of a circle is three times its diameter.

So, he measured the wheel with a rope and checked it, only to find that the circumference of the wheel was a little more than three times the diameter of the wheel. He went to measure the basin again, and the result was the same. He thought that the circumference is not exactly 3 times the diameter, so how much longer is the circumference than the 3 diameters?

Before the Han Dynasty, China generally used three as the value of pi, that is, "three diameter one". This is a large error when calculating the circumference and area of a circle. On the basis of the scientific method of using "circumcision" to find pi created by Liu Hui, Zu Chongzhi used the method of opening and density, and after repeated calculations, found that pi is:

>。This was the most accurate value in the world at the time, and he became the first person in the world to calculate the exact value of the circumferential nuclear rent conversion rate to the seventh decimal place. It wasn't until more than 1,000 years later that this record was broken by the Europeans.

The calculation of pi is an outstanding contribution of Zu Chongzhi in mathematics, and some foreign historians of mathematics call it "Zu rate."

1. The Book of Sui and the Chronicles of the Law left a small record of pi ( ), and the true value calculated by Zu Chongzhi was between and was equivalent to the 7th decimal place, which was simplified into the most advanced achievement in the world at that time. Zu Chongzhi was selected as the first scientist in the world to calculate the value of pi to the 7th decimal place in the World Records Association, creating the world's largest in the China Discipline Association. This record was not broken until the 15th century by the Arab mathematician Al-Qasi.

2. Zu Chongzhi created the "Daming Calendar" and was the first to introduce precession into the calendar; A new leap week of 391 years plus 144 leap months was adopted; For the first time, the number of days in the month of the node (, the number of days in the return year () and other data were accurately measured, and the method of measuring the noon solar shadow length of several days before and after the winter solstice was also invented to determine the time of the winter solstice.

3. He has designed and manufactured water milling, copper machine parts transmission guide cars, thousands of miles of boats, timers and so on. In addition, he also has attainments in music, literature, and evidence, he is proficient in music, good at playing chess, and also wrote ** "Narrative Differences". He is a rare erudite figure in history.
