Book Description
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.

Book Description
This book is a history of the development of mathematical astronomy in China, from the late third century BCE, to the early 3rd century CE - a period often referred to as 'early imperial China'. It narrates the changes in ways of understanding the movements of the heavens and the heavenly bodies that took place during those four and a half centuries, and tells the stories of the institutions and individuals involved in those changes. It gives clear explanations of technical practice in observation, instrumentation, and calculation, and the steady accumulation of data over many years - but it centres on the activity of the individual human beings who observed the heavens, recorded what they saw, and made calculations to analyse and eventually make predictions about the motions of the celestial bodies. It is these individuals, their observations, their calculations, and the words they left to us that provide the narrative thread that runs through this work. Throughout the book, the author gives clear translations of original material that allow the reader direct access to what the people in this book said about themselves and what they tried to do.

Book Description
From #1 New York Times bestselling authors Cassandra Clare and Wesley Chu comes the second book in the Eldest Curses series and a thrilling new adventure for High Warlock Magnus Bane and Alec Lightwood, for whom a death-defying mission into the heart of evil is not just a job, it’s also a romantic getaway. The Lost Book of the White is a Shadowhunters novel. Life is good for Magnus Bane and Alec Lightwood. They’re living together in a fabulous loft, their warlock son, Max, has started learning to walk, and the streets of New York are peaceful and quiet—as peaceful and quiet as they ever are, anyway. Until the night that two old acquaintances break into Magnus’s apartment and steal the powerful Book of the White. Now Magnus and Alec will have to drop everything to get it back. They need to follow the thieves to Shanghai, they need to call some backup to accompany them, and they need a babysitter. Also, someone has stabbed Magnus with a strange magical weapon and the wound is glowing, so they have that to worry about too. Fortunately, their backup consists of Clary, Jace, Isabelle, and newly minted Shadowhunter Simon. In Shanghai, they learn that a much darker threat awaits them. Magnus’s magic is growing unstable, and if they can’t stop the demons flooding into the city, they might have to follow them all the way back to the source—the realm of the dead. Can they stop the threat to the world? Will they make it back home before their kid completely wears out Alec’s mom?
