Über diesen Titel

Reseña del editor:

A collection of working models of sundials and timedials to be cut out and glued. The models include polar, equatorial, sunbeam equatorial, traditional, three-in-one and a nocturnal dial and include a minibook which gives background information, projects and investigations.

Reseña del editor:

There is no doubt that the best way to understand the principles of sundials and timedials is to make working models. Each of the models is cut from thin card and is adjustable for use within the range of latitudes 30 degrees N & 60 degrees N. They work surprizingly accurately and there are many different designs: including Polar; Equatorial; Sunbeam Equatorial; Traditional; Three-in-One; and a Nocturnal. Also included is a minibook which suggests some interesting projects and investigations.
