John, and other list readers,- I first saw discs on almost _all_ the sundials in the sundial "garden" on the Deutsches Museum in München (Munich). When I "got" it, I thought it a great idea. That was in 1998, but they are still there.
Here is a picture on the museum's website. Though hard to see, the discs are there. http://www.deutsches-museum.de/ausstell/dauer/zeitmess/img/poly.jpg Rudolf 52-30'N 4-40'E -----Oorspronkelijk bericht----- Van: John Carmichael Verzonden: maandag 12 juli 2004 22:07 Aan: [EMAIL PROTECTED] CC: Sundial List Onderwerp: Re: Turtle Bay Sundial Bridge opens You are right Bill. That's a great idea! I had never thought about it, but it's true. A flat circular disk that permanently mounted parallel to the dial face will always cast a circular shadow on the face. It's such a simple concept, I wonder why nobody's ever mentioned this before. Do you know of any dials with this type of nodus? I don't. -
