Gautama Siddha
Gautama Siddha, (fl. 8th century) astronomer, astrologer and compiler of Indian descent, known for leading the compilation of the '' Treatise on Astrology of the Kaiyuan Era'' during the Tang dynasty. He was born in Chang'an, and his family was originally from India, according to a tomb stele uncovered in 1977 in Xi'an. The Gautama family had lived in China for multiple generations, ever since his great-grandfather immigrated to China from India. He was most notable for his translation of Navagraha calendar into Chinese. He introduced Indian numerals from zero to nine in 718 CE, but Chinese mathematicians did not find them useful, as they already had the decimal positional counting rods. The '〇' is used to write zero in Suzhou numerals, which is the only surviving variation of the rod numeral system.

It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early Middle Ages, Early, High Middle Ages, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the ...

Scientists From Shaanxi
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science.
