Shiing-Shen Chern was a Chinese-American poet and mathematician. He is best remembered for making significant contributions to topology and differential geometry. Referred to as the father of modern differential geometry, Shiing-Shen Chern is widely regarded as one of the 20th century's greatest mathematicians. He won several prestigious awards, such as the National Medal of Science, Wolf Prize, and Lobachevsky Medal.
Chinese polymath Zhang Heng, or Chang Heng, was, at the same time, a mathematician, an astronomer, a geographer, a poet, a seismologist, an artist, and much more. His countless inventions include the world's first seismoscope. He documented over 2,000 stars and modified the Chinese calculations for pi.
Xu Guangqi, or Paul, was a Chinese official of the Ming dynasty and one of the most prominent Chinese converts before the 20th century. An agronomist, a mathematician, an astronomer, a politician, and an author, he translated many Western works. He was also known as one of the Three Pillars of Chinese Catholicism.
Chinese astronomer, engineer, and mathematician Zu Chongzhi is best remembered for calculating near-accurate approximations for π. He rejected the then-prevalent Yuanjia calendar and introduced the Daming calendar instead. He had also worked on the mathematical theory of music, though his writings haven’t survived the test of time.
Chinese mathematician of the 3rd century, Liu Hui lived in the Cao Wei region during the Three Kingdoms period. He is remembered for his commentary Jiuzhang suanshu, or The Nine Chapters on the Mathematical Art, which included his scientific writings on topics such as the Pythagorean theorem and solid geometry.
Chinese mathematician, meteorologist, and writer Qin Jiushao is remembered for developing a method to solve simultaneous linear equations and polynomial equations, mentioned in detail in his only book, Shushu jiuzhang. Though he became the Qiongzhou governor, he was later dismissed for corruption. He had also initially served the army.
Chinese mathematician and astronomer Li Chunfeng rejected the existing Wuyin calendar and redesigned it later, creating the Linde calendar, using a new armillary sphere, as part of the Imperial Astronomical Bureau. He also wrote several mathematical and historical treatises, apart from contributing to music, metrology, and astrology.
