Hi Jan: In addition to the book by Dava Sobel there's a good movie. Links on the Ukiah Observatory web page below.
The related problem that was much harder to solve is the Latitude. For more on that see: http://www.prc68.com/I/UkiahObs.shtml I live in Ukiah, California, where one of these observatories is located. Another Time Nut you might be interested in reading about is Alfred L. Loomis chronicled in the book Tuxedo Park by Jennet Connant. Discovered and published data showing the effect of tides on pendulum clocks. And of course "Lunar/Solar Tides and Pendulum Clocks (part 1)" at: http://www.leapsecond.com/hsn2006/ch1.htm Have Fun, Brooke Clarke http://www.prc68.com/P/Prod.html Products I make and sell http://www.prc68.com/Alpha.shtml All my web pages listed based on html name http://www.PRC68.com http://www.precisionclock.com http://www.prc68.com/I/WebCam2.shtml 24/7 Sky-Weather-Astronomy Web Cam Jan Fredriksson wrote: > Hi, > > Can anyone point to some good reading on John Harrison, > who in the 18th century devoted his life to making the best > timekeepers ever built and who also constructed and built > the first usable marine chronometer. > > Jan F > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. > _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
