In McLean, Virginia close to Washington, D.C. NASS held its 13th annual conference. At the Analemma Society’s site in Observatory Park, Tony Moss’ dial, the “Jamestown Commemorative Dial,” was dedicated in front of over 50 school children and twice as many adults. This is the first sundial installation in what is planned to be an International Sundial Garden. Other highlights of the sundial tour included the Lyman Briggs Memorial Dial at the National Institute of Science and Technology, the Latitude Observatory (once used to study the daily variation in the earth’s wobble and rotation rate), the Vernon Walker Education Center dial, and the vertical dial on the wall of Jack and Kate Aubert. The conference talks included Roger Bailey on “God’s Longitude and the Lost Colony,” Woody Sullivan’s “Ten Tons of Basalt and Tenths of Degrees,” Fred Sawyer’s discussion on the 17th century battle over the priority of inventing the stereographic quadrant dial, Kevin Karney’s “Variability in the Equation of Time” over geological epoch periods (well, for at least 500 years), and much more. Most impressive was Julian Chen’s “Omnidirectional Lens in Sundials and Solar Compasses” using spheres filled with solution of copper sulfate to focus the sunlight onto a dial.
