Next General Meeting

Saturday, January 20th, 7:00pm
Chabot Space and Science Center, Chemistry Physics Classroom (Enter from the rear loading dock behind the main building. Door will be open).

Dr. Ken Wharton — “Is Quantum Entanglement Magic?”

Entanglement phenomena are the closest thing we have to reproducible magic, and even physicists can’t agree as to what’s really going on. Is it spooky action at a distance, or retro-causality, or conspiracies that govern our choices? And what is a good skeptic to do when every explanatory option seems unacceptable — when nature forces us to train skepticism inward, towards our strongest intuitions? (General audiences welcome!)

Dr. Wharton is a professor of physics at San Jose State University. His research is in the field of Quantum Foundations, where he tries to make sense of phenomena like entanglement without giving up conventional notions of space and time. He also makes an effort to explain Quantum Foundations to a general audience; some of his popular-science writing has appeared in New Scientist, Nautilus, and Aeon.

Upcoming Special Events

RTMC (50th Anniversary): Thursday, May 24 – Monday, May 28
Dark sky observing, Telescope Making Awards, Speakers, and Workshops. This year’s keynote is David Levy. Visit http://rtmcastronomyexpo.org for more information and registration.

Golden State Star Party:
Wednesday, July 11 – Sunday, July 15.
Join hundreds of amateur astronomers for one of California’s best known dark sky observing and astro-photography events.  Visit www.goldenstatestarparty.org for more information and registration. EAS members can book a campsite here.

Barcroft High Altitude Observing (EAS members only):
Sunday August 5th – Saturday August 11th.
Each year, EAS runs an excursion to UC Berkeley’s Barcroft High Altitude Research Station in the White Mountains above Bishop, CA.
This is a total of 6 possible nights. Everyone needs to leave by noon on Saturday.

At 12,000 feet, with often bitterly cold temperatures and miles of gravel and shale roads to traverse, this excursion is not for the faint of heart. The facilities, however, are exceptional. Food and lodging is included. Oxygen is not! To reserve your spot, you must be an EAS member, and you need only click the button below to pay for your intended stay. For detailed information, download our overview of the Barcroft event by clicking here.

Nights reserved
Dates requested (e.g. “14-16”)

Telescope Makers Workshop

The Telescope Maker’s Workshop is one of few regularly scheduled such workshops in the world! Every Friday from 7 to 10 PM, amateur telescope makers from the bay area meet at the Chabot Space & Science Center and learn how to grind, shape, polish, and figure mirrors for reflecting telescopes, under the guidance of EAS volunteers. The workshop is free; participants pay only for the mirror blanks and grinding tools, which generally cost between $100-$300, depending on the size of the mirror. All the instruction, grinding grit, testing equipment, and camaraderie is free of charge! For more information, email Richard Ozer at rozer@pacbell.net, or come by the workshop any Friday to see what it’s all about.


EAS sends volunteers to schools, libraries, and anywhere curious aspiring astronomers gather. EAS volunteers bring their own equipment or borrow telescopes. Students, parents, and teachers are always thrilled to look through the telescopes and ask questions. You’ll meet all sorts of interesting people and provide a unique and inspiring experience to kids and parents who may have never looked through a telescope before. Find our next event on the calendar above.

Inquire about and request visits by e-mailing EAS Outreach Coordinator Ray Howard at RaymondHow@aol.com. Visit our outreach page to find out about upcoming outreach events.

Members Only Viewing Nights (MOVN)

Once a month, we schedule a Members Only Viewing Night at the Chabot Telescope Deck for both EAS and Chabot members. This is our opportunity to look through Chabot’s historic instruments and research telescope, as well as bring our own equipment to share in a more quiet venue. The schedule for MOVN appears in the event calendar below.
