Fred Sawyer, President of the North American Sundial Society and editor of the Compendium sundial journal will present a lecture on "Gnomonic Tales of Thomas Jefferson (and other Founding Fathers)" on Thursday evening, April 10th at 7pm at the Great Falls Library, VA. Reservations are required. Contact the Fairfax County Libraries for more information.
The lecture will consider sundials in the lives of Thomas Jefferson and other prominent figures of early America such as George Washington and Benjamin Franklin. Rather than serving simply as timekeeping devices, sundials will be seen as academic exercises, inspirations for poetry, symbols of an industrious new country, invitations to relaxation, and opportunities for invention.

Appropriate to NASS’ visit, Harvard had just recently completed a new major exhibit entitled “Time and Time Again” offering conference members a unique view on the changes in time keeping and the social impact of timekeeping technology. On Friday afternoon, NASS members followed the Time Trails through the Harvard campus, locating historical sundials “in the wild” and timepieces in the Semitic, Peabody, and Natural History Museums.
The day was finished by two presentations “Trading in Time: European Pocket Sundials Designed for Colonial Use in American Territories by Sara Schechner and “Portable Sundials in Austrian Museums” by Ilse Fabian.
During Saturday a plethora of sundial talks were presented by NASS members, including “Counting the Sunny Hours” by Roger Bailey to a new “Wandering Gnomon Sundial Designn” by Fred Sawyer. Bob Kellogg presented the making of an animation illustrating the Ibn al-Shatir sundial proposed for Observatory Park in Virginia for the Analemma Society. One of the most color presentations was Art Paque’s update on Solargraphy, illustrating the technique of forming daily images of the sun a photographic paper that at the last is digitally scanned and preserved.
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.

In 1961 Professor Ronald Bracewell at Stanford University created an X shaped array (called a “Chris-Cross array” for W.R. “Chris” Christiansen) using 32 10-foot diameter dish antennas to form a radio spectroheliograph nestled in the hills of Palo Alto, California.
Tom Carpenter, a member of the Hampton fire company for 44 years, presented plans for a 9/11 memorial to the Borough Council at the beginning of 2012 and Councilman James Cregar began designing the memorial as a sundial using beams recovered from Ground Zero of the Twin Towers.
