Curved Spaces – Oct 25

/ , , / , , , , , /

The geometry of the ancient Greeks took place on an ideal, infinite, flat plane. In the millenia since then, mathematicians have opened our minds to the more general and flexible geometries of curved spaces — from the fabric that makes up our clothing, to the spacetime around a black hole. Now, we can develop an 'insider's view' of such geometries. This newfound intuition has intriguing applications, including to recent images from the James Webb Space Telescope! Such understanding allows us to better appreciate Einstein's greatest insight: that gravity is not a force, but rather a consequence of living in a curvy world.

Our speaker, Dr. Steve Trettel, is Assistant Professor of Mathematics at the University of San Francisco. He is a geometric topologist who loves computer graphics and a good bike ride.

Search for ET – Oct 15

/ , , / , , , , , , , /

Humans have sought "signs from above” for millennia. The scientific search for extraterrestrial intelligence (SETI) began circa 1960, and, today, grows ever deeper and more technologically diverse. The scope of modern research is breathtaking. Methods include targeted searches for electromagnetic (EM) signals near known Earth-like exoplanets, continuous EM scans over the entire sky (e.g., PANOSETI at the Bay Area's Lick Observatory, pictured), the hunt for exotic forms of communication, and the careful search for ET artifacts on/near Earth.

Our speaker, Dan Werthimer, is Chief Scientist at the Berkeley SETI Research Center. He is also co-founder of SETI@Home, and principal investigator of CASPER, the Center for Astronomy Signal Processing and Electronics Research. Since 1979, Dan has helped to design and build numerous sensitive tools for the detection of ET. In 2019, Dan earned Wonderfest's Carl Sagan Prize for Science Popularization. And, in 2021, he received the prestigious Frank Drake Award of the SETI Institute.

Poincaré

Poincaré Beauty – Sep 24

/ , , / , , , , , , /

At the turn of the new millennium, a renowned mathematics institute pledged $7 million for the solution of seven special math problems, $1 million each. Only one of these seven Millennium Prize Problems has been solved. That problem, originally posed over a century ago by Henri Poincaré, asked a deep question about the nature of 3-dimensional space. Its resolution opened our (mathematical) eyes to the beauty of 3-dimensional universes — filled with curved geometries, wormholes, and a whole lot of pretty math. This presentation, assuming only a high school math background, will explore the beauty of these spacey ideas in mathematical topology.

Our speaker, Dr. Steve Trettel, is Assistant Professor of Mathematics at the University of San Francisco. He is a geometric topologist who loves computer graphics and a good bike ride.

Extraterrestrial Life – Sep 5

/ , , / , , , , , , , , , /

An August-24th New York Times article about audacious astronomer Avi Loeb concludes with this: "Now, that being said, if [Dr. Loeb] finds something, it's life-changing ... It will change everything." What was "being said" referred to professional academic complaints about Dr. Loeb's alleged "transgressions against scientific norms and protocols." However, no one disputes the excitement of Prof. Loeb's investigations. Wonderfest joins the Commonwealth Club to present controversial Harvard astronomer Avi Loeb in conversation about ideas in his latest book, Interstellar: The Search for Extraterrestrial Life and Our Future in the Stars. That conversation will explore some vital — if highly speculative — long-term questions: How do we prepare for first contact with ET? And how can our species itself become interstellar?

Dr. Avi Loeb is Professor of Science and former chair of the Astronomy Department at Harvard University. During this online event, he will be in conversation with the Commonwealth Club's George Hammond.

Astrobiology, online – June 27

The age of astrobiology has begun. We have a whole solar system — and a galaxy of star-warmed worlds beyond — to explore for life. How do we look for life here and way out there? How will we know it when we find it? Our exploration begins at Earth. We must apply what we are learning about our own amazing home planet to our search for life beyond.

Our Speaker, Dr. Penny Boston, was Director of NASA's Astrobiology Institute at Ames Research Center. Access her presentation at the Mt Tam Astronomy YouTube channel, linked below. Dr. Boston will answer questions during the video premiere AND, afterward, via Google "Meet."
