Volumes I and II of the major series: China: its language, geography and history ; Chinese philosophy and scientific thought.

This fifth volume abridgement of Joseph Needham's monumental work is concerned with the staggering civil engineering feats made in early and medieval China.

A section of Volume IV, part 1 and a section of Volume IV, part 3 of the major series:

The world's preeminent authority on Chinese science explores the philosophy, social structure, arts, crafts, and even military strategies that form our understanding of Chinese science, making instructive comparisons along the way to similar elements of Indian, Hellenistic, and Arabic cultures. A major portion of the book concentrates on Taoist alchemy that led not only to the invention of gunpowder and firearms, but also, through the search for macrobiotic life-elixirs, to the rise of modern medical chemistry.

Volume 2 contains Volume III and a section of Volume IV, Part 1 of the major series: Mathematics, Astronomy, Meteorology, Geography & map-making, Geology & related sciences, Physics (excluding electricity & magnetism).

Digesting the main sections of Volume IV of Dr. Needham's magnum opus, this book is concerned with the immense advances made in early and medieval China in mechanical engineering. It discusses in simple but eminently readable terms the status of engineers, their tools and materials, then basic mechanical principles, followed by machinery powered by animals, man and even by steam, vehicles for land transport, six centuries of hidden clockwork, windmills and aeronautics. Since China was far ahead of the West in ancient and medieval times, this volume helps make clear the immense debt owed by Western civilization to the Chinese. Such debts included the important mechanical principles of transforming rotary motion to a to-and-fro motion of a crank and vice-versa. They invented the first efficient harness for horses and the first mechanical clocks.

A reissue with a foreword and supplement, of a modern classic published in 1960. The invention of the mechanical clock was one of the most important turning points in the history of science and technology. This study revealed six centuries of mechanical clockwork preceding the first mechanical escapement clocks of the West of about AD 1300. Detailed and fully illustrated accounts of elaborate Chinese clocks are accompanied by a discussion of the social context of the Chinese inventions and an assessment of their possible transmission to medieval Europe. For this revised edition, Dr Joseph Needham has contributed a new foreword on recent research and perceptions. In a supplement John H. Combridge details a modern reconstruction of Su Sung's timekeeping device, which together with textual studies modifies our understanding of this important early technology.
