Dials of Interest
Sundials of significant interest either because of artisan, design, history, or placement. An unusal set of dials that should stir anyone's interest
Thanks to Andy Robertson
Recent examination of our Sundial Registry revealed dials that no longer exist and have been replaced with something else that might resemble a sundial, but isn't. Consider the brief entry of Dial 56 that may have once existed in Albuquerque, New Mexico on 9 Mimosa Road:
Eight years ago the University of Western Australia (UWA) commissioned a talented graduate, artist Shaun Tan, to create an impressionistic sundial for the 100th anniversary of UWA. The fundamentals of the west-facing sundial were delineated by UWA Professor Peter Kovesi of the Geophysics and Image Analysis Group.
The Battle Point Astronomical Association, founded in 1992, provides astronomical observing for science education and public enjoyment at Ritchie Observatory and Planetarium in Battle Point Park on Bainbridge Island, Washington.
Telling Time with Precision
(By Permission - Bill Gottesman)
The Andalusia Star News reports that the Lurleen B. Wallace (LBW) Community College in Andalusia, Alabama, has a new timepiece that President Herb Riedel says, “… is a device used for practical purposes to keep time, but they also take on a symbolic meeting. For a college campus, I thought it would be very appropriate because it combines science and art.”
Indeed, the sundial is a large helical sundial, a modern “Renaissance” sundial designed by Bill Gottesman of Precision Sundials in Vermont.

In 2002, the North American Sundial Society recognized John Carmichael with the Sawyer Dialing Prize as an eminent artisan who creates a wide variety of sundials, principally in stone and glass. In recognition, John received a small brass equatorial sundial made by the renowned British artisan Tony Moss. But for nearly a decade the sundial remained on John's workbench never seeing the full light of day.
Recently Mr. Carmichael completed a 24:1-scale model railroad in his back yard (http://www.flickr.com/photos/jlcarmichael/sets/72157632430552837/with/8348506244/). Now his Sawyer Dialing Prize sundial finally sits in the Arizona sun as a miniature "Monumental Sundial" at the Trolley Station. At the 24:1 scale, the 3-inch dial assumes the proportion of a large 6-foot equatorial sundial. You can see John Carmichael's dials at http://www.sundialsculptures.com/.
What can 62 LEGO bricks build? An equatorial sundial. A recent dial building project demonstrates a very nice looking sundial dial built from regular LEGO elements. The design is a classic equatorial sundial using a central north-pointing rod gnomon with shadow cast only hourly segments tilted at 15 degree increments. The base swivels such that it can be adjusted for any latitude.
The building blocks use 1xN plates placed side by side on the underside of a 1x4x5 arch, creating the hourly progression of 15 degree tilted tiles. In the design shown, two blue plates in the center bracket the noon mark. Outer blue plates indicate 6am and 6pm. All you need to do is paste on the hour numerals.
On September 22, 2011 Penn State University dedicated a massive granite sundial donated by trustee and alumnus Joel Myers. Designed and sculptured by artist Mark Mennin, it is installed in the university's arboretum. At the dedication Myers said, "We wanted to create something unique...The sundial is to be a destination". Though still lacking a few final touches, such as a bit of polishing, the large granite dial is functional and tells time to the nearest minute.

A three dimensional sundial house? You can find it at 10 rue du Diebach, Cosswiller near Strasbourg in the countryside of Alsace in France. Eric Wasser has created the "Heliodome", a tilted circular building aligned with the earth's polar axis that is a far cry from the old Buckminister Fuller "Bucky Domes".
The house has a glassed southern exposure to allow sunlight during the winter, but from the equatorial belt forward the house has a nearly conventional roof providing shade during the summer. As Wasser explains on his website, "The passive solar house is an architectural volume, a Heliodome, determined by the diurnal and annual trajectory of the sun."
