▼a This book is an exposition of the lesser-known work of one of the giants of the 18th century longitude story, the maverick clockmaker John Harrison (1693-1776). Harrison's background, methodology, and thinking. For those with a practical interest, the book is an excellent starting point for anyone wishing to make a clock of this type. |
