DOWNLOAD EBOOK →Harrison Decoded: Towards a Perfect Pendulum Clock brings together the output of a forty-year collaborative research project that unpicked and put into practice the fine details of John Harrison's extraordinary pendulum clock system. Harrison predicted that his unique method of making pendulum clocks could provide as much as one-hundred-times the stability of those made by his contemporaries. However, his final publication, which promised to describe the system, was a chaotic jumble of information, much of which had nothing to do with clockwork. One contemporary reviewer of Harrison's book could only suggest that the end result was a product of Harrison's 'superannuated dotage.' The focus of this book centres on the making, adjusting, and testing of Clock B which was the subject of various trials at the Royal Observatory, Greenwich. The modern history of Clock B is accompanied by scientific analysis of the clock system, Clock B's performance, the methods of data-gathering alongside historical perspectives on Harrison's clockmaking, that of his contemporaries, and some evaluation of the possible influence of early 18th century scientific thought.

DOWNLOAD EBOOK →A General History of Horology describes instruments used for the finding and measurement of time from Antiquity to the 21st century. In geographical scope it ranges from East Asia to the Americas. The instruments described are set in their technical and social contexts, and there is also discussion of the literature, the historiography and the collecting of the subject. The book features the use of case studies to represent larger topics that cannot be completely covered in a single book. The international body of authors have endeavoured to offer a fully world-wide survey accessible to students, historians, collectors, and the general reader, based on a firm understanding of the technical basis of the subject. At the same time as the work offers a synthesis of current knowledge of the subject, it also incorporates the results of some fundamamental, new and original research.

DOWNLOAD EBOOK →With the discovery of the Treasure of the Land behind them, Harrison Cross and his adventurer friends find an ancient, leather-bound manuscript mixed in with their newfound bounty. But, after deciphering the scripture's cryptic code they realize the book contains clues to a grander treasure, the Talisman of Unification. The righteous warriors are instructed to traverse the land in search of jewels, artifacts, and the blood of a wicked red dragon, all pieces to a greater whole, in order to fulfill their destiny as the land's new Overlords. Unbeknownst to our heroes, the evil King Holleris sensed the removal of the ancient scripture from its resting place and has sent out his minions to bring the book back to him. With a ransom of 10,000 gold pieces for its safe return, the king has more than enough suitors.

With the odds heavily stacked against them, Harrison and his friends follow the clues that may lead them to their ultimate destiny-rulers of the land. Will they succeed? Or will the evil king tighten his grip on the unsuspecting countryside?
