Orrery: a story of mechanical solar systems, clocks, and English nobility

Description

Setting the scene -- Honest George, chronometers and the mystery of the disappearing proto-orreries -- Orrery : the man and the model -- A closer look at gear calculations, time corrections, escapements, and orbital resonance -- The clockmaker's London -- Modern and orrery times compared -- Appendix 1: A select timeline -- Appendix 2: glossary.;"To find the true story of the orrery, this book takes the reader to the vibrant, tumultous London of the 1600s. A mechanical model that shows the movements of the Moon and planets, the orrery takes its name from the Boyle family -- the Earls of Orrery. Here is the fascinating story of the origins of this intricate device. Orreries are found everywhere. They appear in paintings, on the side of royal clocks, in stately home hallways, and of course, in museums all over the world. Scientific instruments to demonstrate the movements of the planets and predict their positions using measuring devices, they were devised largely by clockmakers, but many others played a role too and are given due credit. The story of the Boyles is not just relevant to a tiny corner of Ireland, but spans history. "Orrery" highlights the process of discovery and humankind's universal fascination with the heavens, providing a fascinating example of the relationship between innovative thinking (invention) and precision engineering (execution). It will appeal to anyone interested in popular astronomy, astronomical mechanical devices, scientific instruments, the history of clocks - and even the history of aristocratic and prestigious families!"--Back cover.
