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

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

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.

The second volume of Dr Joseph Needham's great work Science and Civilisation in China is devoted to the history of scientific thought. Beginning with ancient times, it describes the Confucian milieu in which arose the organic naturalism of the great Taoist school, the scientific philosophy of the Mohists and Logicians, and the quantitative materialism of the Legalists. Thus we are brought on to the fundamental ideas which dominated scientific thinking in the Chinese middle ages. The author opens his discussion by considering the remote and pictographic origins of words fundamental in scientific discourse, and then sets forth the influential doctrines of the Two Forces and the Five Elements. Subsequently he writes of the important sceptical tradition, the effects of Buddhist thought, and the Neo-Confucian climax of Chinese naturalism. Last comes a discussion of the conception of Laws of Nature in China and the West.

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.
