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).

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.

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.

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.

In On Their Own Terms, Benjamin A. Elman offers a much-needed synthesis of early Chinese science during the Jesuit period (1600-1800) and the modern sciences as they evolved in China under Protestant influence (1840s-1900). By 1600 Europe was ahead of Asia in producing basic machines, such as clocks, levers, and pulleys, that would be necessary for the mechanization of agriculture and industry. In the seventeenth and eighteenth centuries, Elman shows, Europeans still sought from the Chinese their secrets of producing silk, fine textiles, and porcelain, as well as large-scale tea cultivation. Chinese literati borrowed in turn new algebraic notations of Hindu-Arabic origin, Tychonic cosmology, Euclidian geometry, and various computational advances. Since the middle of the nineteenth century, imperial reformers, early Republicans, Guomindang party cadres, and Chinese Communists have all prioritized science and technology. In this book, Elman gives a nuanced account of the ways in which native Chinese science evolved over four centuries, under the influence of both Jesuit and Protestant missionaries. In the end, he argues, the Chinese produced modern science on their own terms.
