prudenceb Posted January 27, 2019 Share Posted January 27, 2019 (edited) Intro to Celestial Navigation AND Climate Change 101 Two Separate Talks by John Huth in One Fascinating Day! Saturday, March 2 - 10:30 am to mid afternoon - REI Community Room, Reading MA Club member and Harvard physics professor, John Huth, has once again generously agreed to help us expand our field of knowledge by presenting two separate talks relevant to our paddling community. John wrote up a brief summary of each talk to whet our appetites: Introduction to Celestial Navigation Before the advent of GPS, sailors on the open ocean had to rely on sightings of celestial objects to find their location on earth. What used to be a fairly common practice is now in in danger of extinction. GPS is exceptionally vulnerable to jamming and spoofing. As a result the US Navy has reinstated courses in celestial navigation. This introduction outlines the basics of celestial navigation for the novice, and points to directions on how to develop this as a usable skill. Climate Change 101 In the news, we mostly hear the classic "both sides" on climate change. But, the actual science of climate is fascinating and accessible to the educated lay person. In this presentation, I use the US climate report mandated by Congress as a jumping off point to examine the science of climate. In addition to the well know greenhouse effect, I look at the uncertainties in climate modeling, and other 'forcing functions', such as volcanic eruptions, variations in solar output, and deforestation. This event is open to paid club members only. Please RSVP on the club calendar. Prudence Edited January 27, 2019 by prudenceb Link to comment Share on other sites More sharing options...

prudenceb Posted February 26, 2019 Author Share Posted February 26, 2019 If no preferences suggested, let's go with original plan: this started as nav and we added on the other, so do nav first - unless others have stong thoughts otherwise.

David M Posted February 26, 2019 Share Posted February 26, 2019 (edited) Will there be a scheduled break for lunch and time slots for both presentations? Edited February 26, 2019 by David M Link to comment Share on other sites More sharing options...
JohnHuth Posted February 27, 2019 Share Posted February 27, 2019 As far as I'm concerned - yes, there will be a break for lunch. So probably 10:30, break at 11:15 or so, back to it at 11:25 - maybe until 12:30 at the latest. Lunch Reconvene 1:00 (?) . Talk 1-1:45, break, reconvene at 1:55, talk until 3 PM. That's just a rough estimate. Link to comment Share on other sites More sharing options...
