Design, Construction, and Use
- How do you make a polar sundial?
- What hours can a north-facing sundial indicate?
- How can you find your birthday on a horizontal sundial?
These and other intriguing questions are answered in this easily comprehensible and well-illustrated book which introduces the fascinating world of sundials, their design, construction and use.
It is the only book which gives practical examples of how to build a sundial as well as looking at the astronomical concepts behind their design.
It describes how sundials work, shows the calculations involved in their construction and also gives a comprehensive history of time measurements.
But because a sundial is not just a theoretical instrument, the book also turns theory into reality and shows how a proper working model can be constructed
