Reviews
... a much-needed 'materials and methods' handbook ... It gives the reader a staggering amount of factual details on materials, methods, and the results of scrupulous experiments., ... the constant effort to ensure that opinions which diverge from his own are duly and respectfully noted; punctiliousness in acknowledging sources, and ensuring that all contributions to the knowledge-base by even the most minor personages are given full recognition - those are the attributes of Bob Matthys' book which (even more than its wealth of information and ideas) will ensure that it becomes a classic.

Synopsis
Almost all of a pendulum clock's accuracy resides in it's pendulum. If the pendulum is accurate, the clock will be accurate. In this book, the author describes how to make a more accurate pendulum or pendulum clock. All scientific aspects of the pendulum design and operation are explained in simple terms and backed up with experimental data., The Shortt clock, made in the 1920's is the most famous accurate clock pendulum ever known, having an accuracy of one second per year when kept at nearly constant temperature. Almost all of a pendulum clock's accuracy resides in its pendulum. If the pendulum is accurate, the clock will be accurate. In this book, the author describes many scientific aspects of pendulum design and operation in simple terms with experimental data, and little mathematics. It has been written, looking at all the different parts and aspects of the pendulum in great detail, chapter by chapter, reflecting the degree of attention necessary for making a pendulum run accurately. The topics covered include the dimensional stability of different pendulum materials, good and poor suspension spring designs, the design of mechanical joints and clamps, effect of quartz on accuracy, temperature compensation, air drag of different bob shapes and making s sinusoidal electromagnetic drive. One whole chapter is devoted to simple ways of improving the accuracy of ordinary low-cost pendulum clocks, which have a different construction to the more expensive designs of substantially well-made ones. This book will prove invaluable to anyone who wants to know how to make a more accurate pendulum or pendulum clock., The Shortt clock, made in the 1920s, is the most famous accurate clock pendulum ever known, having an accuracy of one second per year when kept at nearly constant temperature.

- Feedback automatico di eBay- Feedback lasciato dall'acquirente.Mese scorsoOrdine consegnato puntualmente senza problemi
- c***l (75)- Feedback lasciato dall'acquirente.Ultimi 6 mesiAcquisto verificatoThe item was packaged very well and was shipped promptly and came just as described. The value of this item was VERY well worth it as it is almost one of those "once in a lifetime" positive life-changing opportunity courses that the general public just does not hear about every day that I purchased! I would VERY HIGHLY recommend this seller to anybody as he or she seems EXTREMELY HIGHLY motivated selling here on Ebay!
- e***e (191)- Feedback lasciato dall'acquirente.Ultimi 6 mesiAcquisto verificatoThe seller was very helpful and provided great communication. The seller resolved an issue that occurred during shipping with no additional cost to me. I did receive the item and am very happy with the purchase. I would recommend this seller on ebay.
