Astronomy Smorgasbord Week 2
Sundials in Depth
The simplest sundial is a vertical stick. Then it gets complicated with adjustments for a uniform scale, latitude, longitude within a time zone, daylight savings time, the sun's analemma, and refraction. Elaborate ones give the date and the sun's zodiac position. Clever sundials will be presented beyond the ubiquitous garden type, as well as scholarly texts, worldwide associations, vendors, and typical costs.
