NAWCC Chapter 50 Puget Sound

Programs from the 2018 regional

The theme and exhibit of the PNW Regional is Precision Timekeeping


The exhibit will include examples of precision timing . This can be seen in early examples of water clocks, master clocks, up through cesium clocks. Marine chronometers were good examples of precision timing.

Program speakers include:

Key note address by


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.
