Re: [time-nuts] Harvard, Time and the Dipleidoscope
Dr. Sara Schechner, curator, just posted this on the sundial reflector: The Collection of Historical Scientific Instruments (CHSI) at Harvard University would like to invite you to an informal gathering during this year's HSS Annual Meeting, held in Boston. We will open our museum doors on Friday, 22 November 2013 from 7:30pm to 9:30pm. Wine and cheese will accompany the visit of our two current exhibits: Time, Life Matter: Science in Cambridge AND Time Time Again: How Science Culture Shape the Past, Present, Future. For more information, go to our website: http://www.fas.harvard.edu/~hsdept/chsi-exhibitions.html We are located on the Oxford Street side of the Science Center at Harvard University: Collection of Historical Scientific Instruments Science Center 136 and 251 1 Oxford Street, Cambridge, MA. (map: http://hmsc.harvard.edu/files/museums/files/hmsc_map.pdf) Please join us for this special occasion. We are eager to see old friends and make new ones! Please RSVP to either Dr. Sara Schechner (sche...@fas.harvard.edu) or myself, your two hosts. The Harvard Collection of Historical Scientific Instruments is simply outstanding and there are two large exhibits running at present. I presented a paper on the Dent Dipleidoscope at the August annual meeting of the North American Sundial Society, held in Cambridge this year at Harvard. We toured the Harvard exhibits and enjoyed a lengthy behind-the-scene tour of their extensive collection storage area in the basement. This is surely the largest room of rolling shelves filled with scientific antiques I've ever seen! I serve as Registrar for NASS, maintaining an 8.6 GB database of sundials throughout North America. Sundials, of course, were our first time-telling instruments! By 1850, the Industrial Revolution and the extensive train system in England led to demand for more accurate time than sundials and mechanical clocks of the day could provide. For example, train schedules used London Time (as opposed to local solar time) and showed train arrivals/departures to the nearest minute. The Dent Dipleidoscope was the first instrument available to the layman that allowed identifying correct time within just a few seconds. It was easy to use and relatively inexpensive. My presentation was titled, The Dent Dipleidoscope: A Sundial By Another Name. So, as Time Nuts, we can appreciate that time accuracy has come a long way in just 150 years! If you should happen to be in Cambridge for this event, do visit The Coop bookstore near the Harvard campus. It is an amazing, 5-story high place!
