Arabs also preserved the fire of ancient Greek civilization. The great contribution of the European Renaissance was attributed to the Arabs. Europeans rekindled European civilization by translating these written materials from ancient Greece and Rome. Arab civilization is not only an information bridge between East and West, but also a library for preserving civilization. In fact, Arabic civilization is far more than that. Many modern scientific discoveries come from Arab civilization. After the 2nd century, the Roman Empire in the west and the Han Dynasty in the east gradually declined. Europe entered the dark middle ages for thousands of years, while China experienced turbulent periods such as the Three Kingdoms, Wei, Jin, Southern and Northern Dynasties. Only Arab civilization still stands on Eurasia.

The 8th century to13rd century is the golden age of Islam and the heyday of science and technology, such as the most famous Huala submodule. He was called the greatest scientist before the Renaissance. He has made outstanding achievements in mathematics, geography and astronomy. He is the founder of mathematical geometry. The quadratic equation of one variable that is often used in our middle school textbooks comes from his Algebra.

The level of science and technology in the Arab region is comparable to that of ancient Greece and Rome, and Arab civilization has translated a large number of scientific works of ancient Greece. At the same time, he began to learn papermaking from the Tang Dynasty. In 75 1 year, the Arab Empire and the Tang Dynasty fought a decisive battle to carve up the sphere of influence in Central Asia. It's called the Battle of Talas. In the end, the Arab Empire won, captured a large number of craftsmen in China and learned how to make paper in China. This technology was later spread to Europe, providing a tool for spreading European Renaissance knowledge.

/kloc-After reaching its peak in the 0/2nd century, the Arab civilization was invaded by Mongols and the Arab Empire perished. Except for a few craftsmen, the elites who mastered these scientific knowledge at that time were killed. Since then, their scientific and technological level has begun to decline. However, some scholars believe that the decline of Arab civilization is also related to the suppression of science by religious conservative forces. For example, the observatory used for observation was dismantled and researchers were arrested as heretics. Some scholars believe that the Arab education system mainly depends on religious colleges, which is rigid compared with the scientific innovation of universities at that time. No matter what caused the decline of Arab civilization, the achievements of Arabs in science and technology provided rich theories, materials and research methods for the European Renaissance in the late Middle Ages, which strongly promoted the progress of world science.
