sunflower
Hi all I just finished to design an horizontal sundial adjustable for a range of latitude, in this case from 30° N to 50° N, I also built it with laser cut plywood. Revolving the sunflower changes the angle of the polar style, the latitude is engraved (always by laser) at the base of the sunflower, a green arrow on the horizontal dial point out to it. ciao Fabio --- New Outlook Express and Windows Live Mail replacement - get it here: http://www.oeclassic.com/ --- https://lists.uni-koeln.de/mailman/listinfo/sundial

Re: sunflower
A delightful design! Clever, attractive, and undoubtedly gnomonical correct. Botanically, however, it should be noted that the number of right-hand spirals and the number of lefthand spirals of a sunflower are not equal. Instead, they are (pretty consistently) successive Fibonacci numbers (e.g.: 34 and 55, or 55 and 89, or even 89 and 144).
