ILLUSTRATING SHADOWS is a book covering the design and construction of sundials, from the earliest altitude dials, the evolution of azimuth dials, to the dials based on the
apparent rotation of the sun around the earth's polar axis. Empirical, geometrical, and trigonometrical approaches are demonstrated for all the different dials, formulas are developed
as well as used, and techniques for the design of spreadsheets are discussed. Spreadsheets not only provide the tables in the appendices, but they can also provide dial plate
templates. Additionally, the use of CAD (computer aided design) is covered, and the book is illustrated with CAD throughout. Main book page is here. The follow on book is
ILLUSTRATING MORE SHADOWS, focusing on more advanced dial types and larger outdoor dial building techniques. The author is a member of the North American Sundial
Society as well as the British Sundial Society. He lives in Silver City, New Mexico. If you are in the vicinity, email and perhaps we can meet.
AVIATION STUFF...
I started flying lessons in 1963, was a freight hauler in Merlins and Falcons, a check airman, a B727 flight engineer, an airline pilot flying the Boeing 737 and
retired from the FAA (Federal Aviation Administration) and am now a DPE (Designated Pilot Examiner). I also used to fly competition aerobatics competing
regionally. My relative Lt Thomas Selfridge was the first man killed in powered flight in the USA, the pilot was Orville. My grandfather Sergei de
Bolotoff Wiasemsky was involved in the cross channel ace in the early 1900s but failed
to get off the ground, and my great aunt Violette Selfridge flew a gypsy moth around the
world in 1928 writing a book about it called The Flying Gypsies. My great grandfather was
Harry Gordon Selfridge who founded Selfridges department store in London, England.
