Solar Eclipses: Sometimes Local and Always Spectacular

The OLLI Distinguished Speakers Series presents Professor Jay Pasachoff. As a veteran of 72 solar eclipses—including 35 total solar eclipses, 18 annular solar eclipses, and 19 partial solar eclipses--astronomer Jay Pasachoff is uniquely positioned to share recent scientific work related to eclipses, international coordination of observations, and future plans. What role does mathematics play in predicting eclipses, from the ancient saros observations to Halley’s 1715 map, and up to today’s web-based zoom-and-click maps? How do theoretical predictions based on magnetic-field measurements, emission spectra of high ionization lines, and radio observations compare to the high res images available today?
