Zu Chongzhi s deeds are a little shorter 40 words

Zu Chongzhi (429 A.D. - 500 A.D.) was an outstanding mathematician and scientist in China. During the Northern and Southern Dynasties, the Han people, the characters were far away. He was born in the sixth year of Emperor Yuanjia of Song Wen and died in the second year of Yongyuan, Marquis of Qi.

His ancestral home is Fanyang County, Laishui County (now Laishui County, Hebei). In order to avoid the war, Zu Chongzhi's grandfather Zu Chang moved from Hebei to Jiangnan. Zu Chang once served as Liu Song's "master craftsman", in charge of civil engineering; Zu Chongzhi's father was also an official in the court.

Zu Chongzhi received scientific knowledge from his family since he was a child. When he was young, he entered the Hualin University and engaged in academic activities. In his lifetime, he successively served in the history of Southern Xuzhou (now Zhenjiang City), the government to join the army, the order of Louxian County (now the northeast of Kunshan City), the servant of the confessor, and the captain of Changshui.

His main contributions are in mathematics, astronomical calendars, and mechanics.

In terms of mathematics, Zu Chongzhi calculated the value of pi, and in terms of calendar, Zu Chongzhi created the "Great Ming Calendar" on the basis of long-term observation, accurate calculation and in-depth study of historical documents.

Zu Chongzhi. 's father, Zu Shuozhi, is a small **. He hopes that his son will become a dragon. Zu Chongzhi was less than 9 years old, and he forced Chongzhi to read the Analects

Reading a paragraph is called rushing to memorize a paragraph. Two months have passed, Zu Chongzhi can only recite a dozen lines, so angry that Zu Shuozhi dropped the book on the ground and stopped teaching, and scolded: "You are such a fool!

A few days later, he brought his son again and taught him: "If you study the Bible with your heart, you will become a great official in the future." Otherwise, there is no use.

Now, I'll teach you again, you can't work hard if you don't work hard. ”

However, the more Zu Shuozhi taught, the more angry he became. Zu Chong's game is finished, and the more he reads, the more bored he becomes. He frowned and said indignantly

I will not read this book. The father was so angry that his forehead was sweating, and he couldn't help but stretch out his hand and slap Zu Chong, which made his son cry. At this time, Zu Shuozhi's father, Zu Chang, came.

Asked about the situation, he said to Zu Shuozhi: "If the Zu family is really stupid, if you beat him hard, will he become smarter?" Children are not smart, they will only get more and more stupid.

Zu Chang also said sternly to Zu Shuozhi: "Hitting children often not only does not play a good educational role, but also makes children rude!" ”

Zu Shuozhi said: "I'm also for his good!" He doesn't read the scriptures, and if he goes on like this, he will be able to match anything.

Zu Chang said: "You can't force ducks to put on the shelves. He is stupid in reading the Bible, maybe he is clever in other things!

As an adult, you should carefully observe your child's interest and induce it. Zu Shuozhi felt that his father's words made sense, and agreed not to lock the child in the study to study, and to open his eyes with Zu Chang to the construction site he was responsible for, and to grow knowledge. Zu Chongzhi went to the construction site to play with rural children for a few days, and his knowledge was much richer.

He asked Zu Chang: "Grandpa, why is the moon on the fifteenth day of every month?"

Will it be round? Zu Chang explained: "The moon has its own laws of the Pela shed, so there are gaps and rounds!

The more Zu Chongzhi listened, the more interesting it became. Since then, he has often pestered his grandfather and asked non-stop. Zu Chang said to him:

Child, it seems that you are not interested in scriptures, but you are interested in astronomy! Okay, we have a lot of astronomical almanacs at home, I'll find a few for you to see, and ask me if you don't understand. ”

Zu Shuozhi also changed his opinion of his son at this time, teaching him to read astronomical books every day, and sometimes three generations of grandparents and grandchildren studied astronomical knowledge together. In this way, Zu Chongzhi's interest in the astronomical calendar grew.

Zu Chongzhi once said in his book that Minglun began to "specialize in mathematics and prepare letters, searching for the past and the present" from a very young age. He recorded and examined various documents from antiquity to the time in which he lived.

Hello, now I am here to answer the above questions for you. Zu Chongzhi.

1. The story of Zu Chongzhi: Zu Chong studied natural science all his life, and his main contributions were in mathematics, astronomical calendar and mechanical manufacturing.

2, he is in Liu Hui.

Pioneering exploration of pi.

On the basis of the precise method, for the first time, the "pi" was actuarially calculated to the seventh decimal place, that is, between and the "ancestral rate" proposed by him made a significant contribution to the study of mathematics.

3. Until the 16th century, Arabia.

Mathematician Al Cassie broke the record.

4. The "Great Ming Calendar" written by him.

It was the most scientific and progressive calendar of its time, and provided the correct method for astronomical research in later generations.

5. His main works include "Anbian Treatise", "Fixation" and "Narrative of Differences".

Calendars, etc. 6. Extended information: Zu Chongzhi once said in his writings that he had been "specializing in mathematics" since he was very young.

Searching the Past and the Present".

7. He collected almost all kinds of documents, records, and materials from ancient times to the end of the era in which he lived.

8. At the same time, he advocates never "making false assumptions about the ancients", never shackling himself to the outdated and erroneous conclusions of the ancients, and personally making precise measurements and careful calculations.

9. As he himself said, he always "measured the ruler himself, bowed to the instrument and missed it, looked at every detail, and planned with a poor heart".

10. Due to Zu Chongzhi's reputation for erudition and talent, he was Emperor Xiaowu of the Southern Song Dynasty.

He was sent to the Hualin Academy, an academic research institution of the imperial court at that time, to do research work, and later to serve in the General Ming Temple.

11. At that time, the total Mingguan of Buried Pure was the highest scientific research and academic institution in the country, equivalent to the current Chinese Academy of Sciences.

12. The General Ming Temple is divided into five disciplines: literature, history, Confucianism, Taoism, and yin and yang, and the system of teaching is implemented by discipline, and famous scholars from all over the country are invited to teach, and Zu Chongzhi is one of them.

13. Here, Zu Chongzhi came into contact with a large number of national collections, including books on astronomy, calendars, and arithmetic, which had the prerequisites for reference and expansion.

14. Zu Chongzhi proposed for the first time in the history of astronomy in China that the length of the time when the moon passed through the same intersection of the ecliptic and the white path twice (i.e., the "node month") was 27 2123 days, which was only one hundredth of a day from the current estimated value, that is, less than 1 second, due to solar and lunar eclipses.

Collectively referred to as eclipses), all occur near the yellow and white nodes, so the length of Zu Chongzhi's split potato node month is of great significance for the prediction of solar and lunar eclipses.

15. After calculating the number of days in the node month, it is more accurate to calculate the time of the solar or lunar eclipse. Bend the source ordered.

16. In the "Great Ming Calendar" formulated by Zu Chongzhi, the solar and lunar eclipse times calculated by using the node month are more accurate than in the past, and the actual time of the solar and lunar eclipses is very close.

Zu Chongzhi was an outstanding mathematician and astronomer during the Northern and Southern Dynasties of China. Especially right"Pi"The research is even more than the previous generation. He adopted the method of Liu Hui in the Three Kingdoms period, starting from the regular hexagon, to calculate to 24576 sides, each operation to be repeated twelve times, including addition, subtraction, multiplication, division, and opening of more than ten steps.

At that time, Zu Chongzhi could only use chips (small bamboo sticks) to gradually deduce. If Zu Chongzhi did not have the spirit of tenacious and diligent research, he would never have succeeded in it.

It is said that once upon a time, there was a private school teacher who used to come up with strange tricks to punish his students, but he himself slipped out to play. Once, during a class, a student was naughty and the teacher punished all the students for leaving their backs after school.

Out the 20 decimal places of pi.

Zu Chongzhi (429 500 years), the character Wenyuan, was a native of Fanyang County (now Laishui County, Hebei Province), and was an outstanding mathematician and astronomer during the Northern and Southern Dynasties.

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 for the first time actuarially calculated "pi" to the seventh decimal place, that is, between and , and the "ancestral rate" he proposed made a significant contribution to the study of mathematics.

The "Da Ming Calendar" written by him was the most scientific and progressive calendar at that time, and provided the correct method for the astronomical research of later generations. His main works include "Anbian Treatise", "Fixation", "Narrative of Differences", "Calendar Discussion" and so on.

Zu Chongzhi (429-500), a famous mathematician and astronomer during the Northern and Southern Dynasties. Zu Chongzhi's ancestral hometown is Fanyang County (now Laiyuan, Hebei), in order to avoid war, Zu Chongzhi's grandfather Zuchang moved from Hebei to Jiangnan. Zu Chang once served as Liu Song's "master craftsman", in charge of civil engineering; Zu Chongzhi's father was also an official in the court, and he was knowledgeable and respected.

Zu Chongzhi (429 A.D. - 500 A.D.) was an outstanding mathematician and scientist in China. During the Northern and Southern Dynasties, the Han people, the characters were far away. He was born in the sixth year of Emperor Yuanjia and died in the second year of Yongyuan, Marquis of Qi.

Introduction to Zu Chongzhi Zu Chongzhi (429 AD 500 AD) was an outstanding mathematician, astronomer, writer, geologist, geographer and scientist in China.

--Lemon is sweet.

In 462 (the sixth year of the Song Dynasty in the Southern Dynasty), Zu Chongzhi sent the carefully compiled "Great Ming Calendar" to Emperor Xiaowu of the Song Dynasty to request that it be promulgated and implemented. Emperor Xiaowu of the Song Dynasty ordered those who knew the calendar to discuss the advantages and disadvantages of this calendar. In the course of the discussion, Zu Chongzhi was opposed by Dai Faxing, and Zu Chongzhi refuted it in the article "Historical Discussion and Wisdom".

In the "Calendar", he wrote two famous sentences: "I wish to hear the evidence, and verify the truth", "Floating words carry the blue brigade to depreciate, and stealing is not afraid". In order to distinguish between right and wrong, he is willing to present obvious evidence to discuss with each other, and he is not afraid of those groundless denigrations.

Dai Faxing believes that the method of continuing the tradition in the calendar is "the ancients made seals" and "it is not easy for eternity"; He scolded Zu Chongzhi for "slandering the heavens and reciting scriptures", believing that astronomy and the calendar were "measured by extraordinary husbands" and "not the shallow consideration of the debate bench, and they could be pierced and chiseled". Zu Chongzhi was unimpressed. He retorted that we should not "believe in the past and doubt the present", and if "although the ancient law is sparse, it should always be followed", then what is the reason!

The movement of the sun and the moon and the five stars is "not out of the gods, it is tangible and can be checked, and there are numbers that can be deduced", as long as precise observation and research are carried out, Mencius said that "the solstice of a thousand years old can be sitting", it is completely possible.
