夢溪筆談, Volume 07-10

by Kuo Shen

"夢溪筆談, Volume 07-10" by Kuo Shen is an encyclopedic work published in 1088 during China's Song dynasty. Written during the author's forced retirement, this remarkable collection spans an extraordinary range of subjects—from mathematics and astronomy to medicine, metallurgy, and geology. Shen Kuo records groundbreaking observations about magnetic declination, documents innovations like movable type printing and the navigational compass, and explores natural phenomena including fossils and climate change. The work represents one scholar's ambitious attempt to capture the breadth of knowledge in medieval China.
