Hi all If anyone is interested in educational tools, I found, in the depth of my hard disk, an old paper model I used for a course of gnomonics.
It is inspired to the toothpaste of seventies, with red and white strips (still used today). It shows how the hour planes intersect other planes getting different layout of the hour lines. It is a paper model of 4 pages, pdf format, and I uploaded it here: www.sundialatlas.eu/atlas.php?doc=18 The model also suggests how to start the day just thinking to gnomonics :-) ciao Fabio Fabio Savian [email protected] Paderno Dugnano, Milano, Italy 45° 34' 10'' N, 9° 10' 9'' E, GMT+1 (DST +2)
