Online Via Zoom: Our October 21, 2020 Featured Speaker, John Stocke

Stocke_johnPleiades Wednesday, October 21, 2020, 7:00 PM: GCAS general meeting via Zoom. Unencumbered by a business meeting, we will begin by welcoming our Featured Speaker, John Stocke, Colorado University-Boulder professor of Astrophysical & Planetary Sciences (1985-2017). Dr. Stocke will share the "Secrets of Andean Skies: the Mystery of the Pleiades". If you recall his fascinating talk in March 2019 about “Polynesian Navigation” you will definitely want to join us on Zoom starting at 6:45 to get the audience situated for the lecture to begin at 7:00 PM sharp. A Q&A session with John will follow his lecture. Check your email inbox for your Zoom invitation! As further background to the presentation:

A visit to the traditional Inca tribe, the Qeros, provides the context into which Inca astronomy can be placed. The Inca of western South America created the most extensive and arguably the most successful empire in the pre-Columbian Americas. Widely known for their exquisite stonework, organizational brilliance and beautiful sacred sites like Machu Picchu and Sacsayhuaman, the Inca and their ancestors also were careful observers of the skies above their rugged, vertical lands. John will talk about some of their secrets including the Inca "dark constellations", when the Sun is green, how the brightness of the stars in the Pleiades told the Inca when to plant and why the Inca's year has only 328 days.
