China's most sophisticated system of computational astronomy was created for a Mongol emperor who could neither read nor write Chinese, to celebrate victory over China after forty years of devastating war. This book explains how and why, and reconstructs the observatory and the science that made it possible.

For two thousand years, a fundamental ritual of government was the emperor's "granting the seasons" to his people at the New Year by issuing an almanac containing an accurate lunisolar calendar. The high point of this tradition was the "Season-granting system" (Shou-shih li, 1280). Its treatise records detailed instructions for computing eclipses of the sun and moon and motions of the planets, based on a rich archive of observations, some ancient and some new.

Sivin, the West's leading scholar of the Chinese sciences, not only recreates the project's cultural, political, bureaucratic, and personal dimensions, but translates the extensive treatise and explains every procedure in minimally technical language. The book contains many tables, illustrations, and aids to reference. It is clearly written for anyone who wants to understand the fundamental role of science in Chinese history. There is no comparable study of state science in any other early civilization.

The fifth volume of Dr Needham’s immense undertaking, like the fourth, is subdivided into parts for ease of assimilation and presentation, each part bound and published separately. The volume as a whole covers the subjects of alchemy, early chemistry, and chemical technology (which includes military invention, especially gunpowder and rockets; paper and printing; textiles; mining and metallurgy; the salt industry; and ceramics).

The latest volume in Joseph Needham's magisterial revelation of China's premodern scientific and technological traditions introduces medicine. Five essays are included by Joseph Needham and Lu Gwei-djen, edited and expanded upon by the editor, Nathan Sivin. The essays offer broad and readable accounts of medicine in culture, including hygiene and preventive medicine, forensic medicine and immunology. Professor Sivin's extensive introduction discusses these essays, placing them in their historical and medical context, and surveys recent medical discoveries from China, Japan, Europe and the United States.
