Description
Perpetual Motion; comprising a history of the efforts to attain self-motive mechanism, with a classified, illustrated, collection and explanation of the devices whereby it has been sought and why they failed, and comprising also a revision and re-arrangement of the information afforded by “Search for Self-Motive Power during the 17th, 18th and 19th Centuries,” London, 1861, and “A History of the Search for Self-Motive Power from the 13th to the 19th Century,” London, 1870, by Henry Dircks by Percy Verance NP [Chicago?]: 20th Century Enlightenment Specialty Co. 1916 First Edition Octavo, 366 pages, publisher's original light blue cloth covered boards. Illustrated in black and white. Front hinge internally cracked, slight rubbing and wear, else in good + condition. Perpetual Motion; Comprising a History of the Efforts to Attain Self-Motive Mechanism by Percy Verance is a detailed and often fascinating historical survey of humanity’s centuries-long pursuit of the impossible dream of perpetual motion. Building upon and reorganizing Henry Dircks’ earlier landmark studies, Verance compiles, classifies, and illustrates dozens of proposed “self-motive” machines from the 13th through the 19th centuries, explaining the mechanical principles behind each device and—crucially—why every one of them failed. The book blends technical exposition with historical narrative, offering insight into the inventors, the cultural climate that encouraged such experiments, and the persistent belief that a machine could be made to run forever without energy input. As both a chronicle of scientific misunderstanding and a testament to human ingenuity, it serves as an unusual and valuable reference for historians of science, engineers, and collectors interested in mechanical curiosities and the history of invention.

The very best seller I have encountered on eBay! I plan to do business with Westchester Books again, if they will accept my business. Sadly, I had to return the books I purchased from them, through no fault of theirs. They were patient, responsive, and understanding. If you could choose only one book seller on eBay, Westchester Books is the one you should choose. 5 STARS ALL THE WAY!! Great seller! Fast shipping. Excellent packaging. Great value. I plan to buy again from this seller.
