Literary appreciation
Meng Qian Bi Tan is China's first scientific and technological work, which was called "a milestone in the history of science in China" by the British scientist Joseph Needham. Its content not only reflects the great achievements of natural science and humanities in the Song Dynasty, but also reflects the social reality and contradictory struggle in the Song Dynasty to a certain extent. It is a real documentary.
Shen Kuo is a well-read scholar, and Meng Qian Bi Tan was written when he lived in Meng Xi Park in Runzhou in his later years. This rambling note, which is extremely rich in content, contains the crystallization of his life-long scientific research activities, and records in detail the scientific and technological achievements, laws and regulations, poems and anecdotes at that time, and even gossip and anecdotes.
