Dear All, I have been looking at new U.K. educational website which has a whole category devoted to sundials. Early on, there is section "Finding True North". See:
http://wiki.dtonline.org/index.php/Finding_True_North This is what it asserts: The Sun can be used to find True North quite simply by placing a vertical stake in the ground and noting which direction the longest shadow points to. You may now take a two-minute break while you recover from rolling on the floor in a state of helpless laughter. When you have recovered, ponder this puzzle: Where on the planet would you have to be, and at what time of year, for these instructions to give the correct result? Moral: It is better to learn from other people's mistakes than from your own. Frank King Cambridge, U.K. P.S. The home page of the website is: http://wiki.dtonline.org/index.php/Category:Sundials It won't take long before you notice other erroneous assertions :-) --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
