From the Sui and Tang dynasties to the Ming and Qing dynasties, the most scientific and technologica

Scientific and technological achievements in the Sui and Tang dynasties:

1. Zhaozhou Bridge built in the Sui Dynasty.

It is the oldest surviving stone arch bridge in the world.

2. During the Sui and Tang dynasties, China has invented engraving printing, and the "Diamond Sutra" printed in the late Tang Dynasty

It is the world's earliest surviving engraving print with the date.

3. Tang Dynasty medicine king Sun Simiao wrote "A Thousand Golden Prescriptions".

More than 800 medicines and more than 5,300 prescriptions have been documented.

4. The Tang Dynasty monk and his entourage measured the length of the meridian for the first time, he was the first person in the world to measure the length of the meridian of the earth's sub-chain silver beam with scientific methods, and the monk and his entourage discovered the phenomenon of star movement for the first time, more than 1,000 years earlier than Europe.

5. The pharmacopoeia "Tang Materia Medica" compiled by the Tang ** organization is the world's first monograph on pharmacology officially promulgated by the state.

The world-leading scientific and technological achievements in the Sui and Tang dynasties mainly include:

The Zhaozhou Bridge designed by Li Chun of the Sui Dynasty, the engraving printing of the Sui Dynasty, the monks measured the meridians, and the Tang Dynasty issued a new revision of materia medica.

During the Sui and Tang dynasties, China invented engraving printing, which was one of the four famous inventions in ancient China;

The Zhaozhou Bridge, designed and built by Li Chun of the Sui Dynasty, is the oldest stone arch bridge in the world;

The planning of Chang'an, the capital of the Tang Dynasty, is a model in the history of urban construction in the world, which not only has a reasonable and effective layout, but also has a complete water supply, drainage and heating system, which has had a profound impact on the surrounding urban construction.

Four Great Inventions. Compass, gunpowder, papermaking, printing.

Also, please don't add Yuan and Qing. These two dynasties almost ruined ancient China.

During the Song Dynasty, the world's leading technology was mainly reflected in shipbuilding. We can see this through Zhang Zeduan's "Riverside Scene at Qingming Festival". The small capital city of Bianliang already has such a big ship.

At the same time, Europe did not even have a decent social system, and it was still a slave society.

During the Ming Dynasty, through the efforts of Zhu Yuanzhang and his descendants, China's science and technology developed to a new peak. Various firearms are widely used in the military. Among them, incendiary bottles, tanks, mines, and mines were all invented in the Ming Dynasty. This is by no means apocryphal, it is recorded in the history books.

The Tang Dynasty invented gunpowder, the Song Dynasty invented the compass, before the Qing Dynasty, as long as China is a unified country, China is the strongest and most powerful country in the world, not to mention the four major inventions, China's Northern Song Dynasty has a population of 80 million, the whole world together is less than 60 million, due to the outbreak of the first commercial revolution in human history, the total GDP of the Northern Song Dynasty accounts for eighty percent of the entire world.

In fact, in ancient times, there was no science and technology, chemistry was the basis of science, chemistry did not have it, where did science come from, ancient China always believed that the world was composed of five elements: metal, wood, water, fire, and earth.

The gunpowder of the Sui and Tang dynasties was mixed with alchemy, domestic sulfur, saltpeter, and charcoal in a certain proportion. The movable type printing books of the Song and Yuan dynasties were made of clay and then engraved with common Chinese characters, and typeset and printed according to the content of each book. The Ming and Qing dynasties were advanced navigation technology, and Zheng He's seven voyages to the Western Ocean were made by relying on these treasure ships that could carry a large number of people and materials and detailed charts.
