Beijing North City Thyroid Research Institute To Commemorate The Birth Of Zu Chongzhi

< p > believe that we all know something about a href= "http://sjfzxm.com/news/index_f.asp" > Zu Chong Zhi < /a >. At the time of the birth of Zu Chong, the thyroid Research Institute of Beijing north city will join us in remembering Zu Chong Chong.

Zu Chongzhi is an outstanding mathematician and scientist in ancient China. He has made many contributions in three fields: mathematics, astronomy, calendars and mechanics.

< p > < strong > Zu Chong's introduction < /strong > < /p >

< p > in the Southern Dynasties, the society was relatively stable, and both agriculture and handicraft industry had remarkable progress. "A href=", "http://sjfzxm.com/news/index_f.asp", "economy" and "/a", and the rapid development of culture, thus promoted the advancement of science.

Therefore, during this period, some of the most accomplished scientists emerged in the Southern Dynasty.

< /p >

< p > Zu Chongzhi has a wide interest in natural science and literature and philosophy, especially in astronomy, mathematics and machinery manufacturing, and has a strong interest and in-depth study.

As early as in his youth, he had the reputation of being knowledgeable, and was sent to a Research Institute at that time, Hua Lin Xue, to do research work.

< /p >

< p > he attached great importance to the achievements of ancient studies, but never superstitious and completely listened to the ancients.

In his own words, he must never "falsely push the ancients" but "search for ancient and modern times".

On the one hand, he studied deeply the writings of ancient scientists such as Liu Hsin, Zhang Heng, Kan Ze, Liu Hui, Liu Hong and others, and fully absorbed all the useful things.

On the other hand, he dares to boldly doubt the conclusions of predecessors in scientific research, and corrections and supplements through actual observation and research, thus obtaining many valuable a href= "http://sjfzxm.com/news/index_f.asp" > scientific < /a > achievements.

In the field of astronomical calendar, Daming calendar, which he compiled, was the most precise calendar at that time.

In mathematics, he calculated the circumference of the seven decimal numbers accurately and achieved the best results in the world.

< p > < strong > Zu Chong's life achievement < /strong > < /p >

< p > Zu Chongzhi mainly contributed in three aspects: mathematics, astronomical calendar and mechanics.

In addition, the history records that Zu Chong is proficient in temperament, is good at playing chess, and also writes the novel "narrative difference".

Zu Chongzhi wrote a lot, but most of them were lost.

< /p >

From P, he became interested in astronomy and mathematics.

He collected almost all the documents, records and materials from ancient times until his life, and made detailed measurements and careful calculations in person.

Just like what he said, "we should pay attention to the Guixi ruler, pay attention to the leak, do everything in the least, and plan for the poor."

He studied carefully the work of scientists such as Liu Hsin, Zhang Heng, Zheng Xuan, Kan, Wang Fan, Liu Hui and so on, and refuted their mistakes and exported many valuable results.

Accurate to 7 effective mathematics is a well known example.

< p > the calculation of the park rate PI indicates the mathematical level of a country and a nation.

In ancient China, as well as any other countries and regions in the world, the initial use rate of garden was 3.

This error has been widely used in the Han Dynasty.

After entering the Han Dynasty, the improvement of garden rate has attracted the attention of many scientists, and some work has been done.

The most important is Liu Hui, a mathematician in the Wei and Jin Dynasties. He used the "cut garden" to calculate the weekly rate of 3.14.

< /p >

< p > > a href= "http://sjfzxm.com/news/index_f.asp" > Zu Chong Zhi < /a > achievements in astronomical calendar are mostly included in the Da Ming calendar compiled by him and the "refutation" written by the Daming calendar.

Through careful observation and measurement, Zu Chongzhi found that there were many errors in the Yuan Jia Li compiled by He Chengtian, a famous astronomer at that time, and began to compile the Daming calendar, which was compiled in 462 ad, and is only 33 years old.

Zu Chongzhi made many creative contributions to the compilation of calendars. Daming calendar is one of the best calendars in this era, but it was opposed by the emperor's favourite ministers.

It was not until 10 years after the death of Zu Chong that the Daming calendar was formally promulgated by his son Zu (Sun Huan).

There are many works written by P, especially in astronomy, calendars, mathematics and mechanical manufacturing.
