Tom Van Baak

Tom Van Baak is a physicist and mathematician by education, an operating systems software engineer by profession, and a precision clock enthusiast by passion.
He received a degree in physics and mathematics at Calvin College in Grand Rapids, Michigan. In his career he worked as an operating systems software engineer in Silicon Valley and in Redmond, Washington. His interest in precise time dates from a middle school science project where he built an optically triggered, electromagnetically impulsed pendulum clock from old radio and car parts, balsa wood, and plastic.
More recently he began collecting atomic clocks and created a world-class precision timing laboratory in his home with clocks ranging from marine chronometers to hydrogen masers. He specializes in time measurement and error analysis, in experimenting and education. A virtual museum of his clock collection and numerous lab reports are on his LeapSecond.com website. Van Baak is also the creator of the time-nuts group, a loose collection of hundreds of individuals around the world who collect, repair, create, or experiment with quartz, GPS, rubidium, and cesium time and frequency standards as a hobby.

Banquet Speaker

Prof James Evans

 (University of Puget Sound) discussing new revelations about the Antikythera Mechanism. This was discovered in early 1900’s in a Roman ship wreck and is dated to around 100BC. This mechanical device predicted solar and lunar eclipses and was based on the Babylonian 235 month calendar.
