Science and Civilisation in China, Part 2, Mechanical Engineering
Author: Joseph Needham
language: en
Publisher: Cambridge University Press
Release Date: 1965-01-02
As Dr Needham's immense undertaking gathers momentum it has been found necessary to subdivide volumes into parts, each to be bound and published separately. The first part of Volume 4, already published, deals with the physical sciences; the second with the diverse applications of physics in the many branches of mechanical engineering; and the third will deal with civil and hydraulic engineering and nautical technology. With this part of Volume 4, then, we come to the application by the Chinese of physical principles in the control of forces and in the use of power; we cross the frontier separating tools from the machine. We have already noticed that the ancient Chinese concept of chhi (somewhat similar to the pneuma of the Greeks) asserted itself prominently in acoustics; but we discover here that the Chinese tendency to think pneumatically was also responsible for a whole range of brilliant technological achievements, for example, the double-acting piston-bellows, the rotary winnowing-fan, and the water-powered metallurgical blowing-machine (ancestor of the steam-engine); as well as for some extraordinary insights and predictions in aeronautics.
The Nature and Uses of Lotteries
Thomas Gataker was a disputatious Puritan divine. His The Nature and Uses of Lotteries (1627) was the first systematic exposition of a modern view of lotteries, not just as a form of gambling, but as a fair method of division. Gataker approved of these uses, but condemned divination and sorcery using random signs or spells. This important treatise is often referred to, but is generally inaccessible due to its rarity and old-style of language. The text of this edition has been fully modernised, with notes on important sources used by Gataker and includes a new introduction.
