Dear Fellow-Dialists, The Chair of our Physics Department sent me a reference to the following site, from the publication *Physics in Canada*, which might interest you, especially those who use dials to motivate school children to learn about the sun-earth system. (Interestingly enough, the ancient writer, Geminos, uses phenomena seen on sundials, for exactly such didactic purposes.) Anyway, the site is: http://www.cap.ca/en/article/digital-sundials-internet-new-way-using-ancient-technology When you get to the site click on the pdf file. (We're having great weather for sundials here in Vancouver and I hope you're having the same!) -Len Berggren -- J. L.
