Our astronomy club CAABM of Boucherville was impressed by the presentation on the history of Sun Dials by sun dial maker Jean-Serge Dion of Drummondville, Qc. He explained the history of time keeping and how we learned of to track time through antiquity. We learned of to make solar clocks and solar calendars ourselves. Mr. Dion explained it in such a wonderful way that a child could build one. Although I wasn't able to stick around for the whole presentation, I very much enjoyed it...
