In the past I have not had much time for sundials and woudn't have one in my garden if you paid me. However we have just come back from holidays and we visited the Tropic of Capricorn and i had a good look at the sundial there and i was amazed at how accurate it was only about 1 minute slow. Is this because it was right on the tropic and the calculations could be made more accurately? Another thing was that it ran backwards ie anticlockwise, why is this ? does anyone know? Is it because I was at the Tropic of Capricorn and that is in the Southern hemisphere? do sundials work the other way in the Northern Hemisphere? If so why do clocks run clockwise? Any one have and views or any real knowlege? Regards ian
