142: The biggest clock with Rob Seaman

Rob Seaman  of the Catalina Sky Survey talks about time, and why you need to know the time to discover asteroids and comets. He explains how he installed a highly accurate clock, and makes the case that "natural time" is better than "cold, heartless atomic time."  Above: Self-portrait of Rob Seaman, taken during the commissioning of a spectrograph for calibration purposes.
