Time tamed : the remarkable story of humanity's quest to measure time /Nicholas Foulkes. ''For more than 25,000 years, mankind has sought to understand and measure the passing of time, in the process creating some of the most remarkable and beautiful timepieces. Now, in Nicholas Foulkes's lavishly illustrated book, the battle to tame time is brought vividly to life. From the baboon bone dating back to the palaeolithic era that marked the lunar cycle and on to the 3500-year-old water clock at Karnak, from our earliest days mankind has sought to track the passing of time. More recently, the struggles to measure longitude and to create a workable train timetable across the vast, open expanse of the United States have inspired new developments. In Time Tamed, Nicholas Foulkes reveals how we have done this by focusing on some of the most significant developments in timekeeping across the ages. He also highlights the most stunning and lavish clocks and watches in history - from Big Ben to Rolex - for telling the time has never been purely about function, but also about design. The book is filled with remarkable tales, from the 14th century monk in St Albans who created one of the first mechanical clocks to the Holy Roman Emperor who built a clock into an automated ship that fired a cannon to summon guests to dinner. More recently, there was the Surrey woman who used a Napoleonic era watch to 'deliver' the accurate time to London shopkeepers in the wartime era of Churchill, or the Swiss denture maker who solved a tricky problem for the Indian Raj's polo players. Time Tamed is a book you'll want to spend many hours enjoying.''--Provided by the publisher. 2019. • BOOK • 1 copy available. 681.11309
Instruments and the imagination / Thomas L. Hankins and Robert J. Silverman. "Thomas Hankins and Robert Silverman investigate an array of instruments from the seventeenth through the nineteenth century that seem at first to be marginal to science--magnetic clocks that were said to operate by the movements of sunflower seeds, magic lanterns, ocular harpsichords (machines that played different colored lights in harmonious mixtures), Aeolian harps (a form of wind chime), and other instruments of "natural magic" designed to produce wondrous effects. By looking at these and the first recording instruments, the stereoscope, and speaking machines, the authors show that "scientific instruments" first made their appearance as devices used to evoke wonder in the beholder, as in works of magic and the theater. The authors also demonstrate that these instruments, even though they were often "tricks," were seen by their inventors as more than trickery. In the view of Athanasius Kircher, for instance, the sunflower clock was not merely a hoax, but an effort to demonstrate, however fraudulently, his truly held belief that the ability of a flower to follow the sun was due to the same cosmic magnetic influence as that which moved the planets and caused the rotation of the earth. The marvels revealed in this work raise and answer questions about the connections between natural science and natural magic, the meaning of demonstration, the role of language and the senses in science, and the connections among art, music, literature, and natural science."--Provided by the publisher. 2014. • FOLIO • 1 copy available. 681.2
HMS Centurion, 1733-1769 : an historic biographical-travelogue of one of Britain's most famous warships and the capture of the Nuestra Senora De Covadonga treasure galleon /Shirley Fish. "When the Centurion and a squadron of six vessels and 1,959 men and boys set out from England in 1740, on a round-the-world expedition, they were unaware of the terrifying events that awaited them in the days ahead. The squadron, under the command of Commodore George Anson, had departed from England with every hope of a successful mission to harass and take prizes in the Spanish possessions of the Americas and in Asia. The journey proved more challenging than anticipated, and at times, it seemed nightmarish and beyond anything experienced by the crew. The ship survived two huge waves and a lightning strike. Then, there was the great loss of life amongst the crew who perished due to the devastating symptoms of scurvy. Despite these setbacks, there were moments of pure joy, especially when the Centurion captured the fabulously wealthy Manila-Acapulco Galleon in the Philippines, the Nuestra Senora de Covadonga. Throughout the Centurion's career as a royal naval warship in the eighteenth century, she played a role in the capture of Quebec during the French and Indian War and the invasion of Havana in the Seven Years War. She was also instrumental when dealing with the Barbary Corsairs of Algeria and Morocco. Amongst the famous men who sailed on this vessel were John Harrison, the inventor of the first maritime sea clock, and Joshua Reynolds, the celebrated portrait painter. The details of the journeys to the Americas, Asia, and Europe are described in this biographical-travelogue of the Centurion."--Provided by the publisher. 2015. • BOOK • 1 copy available. 623.82CENTURION
Sound of the waves : a WW2 memoir, how scientists worked to defeat the U-boat threat during the Battle of the Atlantic /E.A. Alexander. "When German U-boats threatened to starve Britain into submission by cutting off food supplies in WW2, sonar scientists and engineers worked against the clock to improve anti-submarine detection in order to defeat them, to guide the X-Craft that attacked the German battleship, KMS Tirpitz, and the craft used in the D-Day landings. There has long been - and continues to be - great interest in WW2 submarine warfare which will often focus on the craft, the men who commanded them and the equipment developed for them but the lives and endeavours of those who developed, perfected and adapted the sonar on which they depended has not been widely appreciated. Many of the personal and specific details mentioned within Sound of the Waves have never been divulged until now. Seen through the eyes of Eric, a bright young physical chemist, this memoir describes in intimate detail what life was like for the talented men and women working for the British Admiralty at Her Majesty's Anti-Submarine Experimental Establishment in Scotland and the Top Secret projects they were involved in. The scientific and technical advances achieved at the Establishment during the war years are explained in uncomplicated terms but Sound of the Waves also reveals that these scientists and engineers were not simply part of Churchill's 'army of boffins ' working in a vacuum but were ordinary people with families and interests outside of their fields of study. This very personal account of the life and research of a young scientist and his colleagues is therefore as much a social history of the war years as a history of underwater weapons in WW2. Flashbacks to Eric's childhood give a clue as to how a curious and creative mind can be nurtured and how a dyslexic child can excel in the sciences. Eric Alexander was born in South Africa in 1916. He came to England prior to the start of the Second World War. It was on gaining his doctorate at Oxford University in 1941 that he was invited to join the Admiralty as an Experimental Officer to improve anti-submarine detection devices. After the war he made his career with the Admiralty as a senior sonar scientist in Dorset, England. In 1966 he was seconded to the diplomatic service of the Foreign Office and appointed Scientific Councellor to the British Embassy in Moscow."--Provided by the publisher. 2020. • BOOK • 1 copy available.
