Theoretical Physicist Dr. Jim Gates - TMO Background Mode Interview

Dr. Jim Gates is a theoretical physicist and currently the Brown Theoretical Physics Center Director, Ford Foundation Professor of Physics, Affiliate Mathematics Professor, and a Watson Institute for International Studies & Public Affairs Faculty Fellow at Brown University. He is known for his work on supersymmetry, supergravity, and superstring theory.

We opened the show with a discussion of Jim’s early career, a B.S. with a dual major in mathematics and physics at MIT and, later, his Ph.D. in physics, also from MIT. In the heart of the podcast, Jim explained Superstring theory—its successes, failures and issues with dark energy. He also explained supersymmetry and supergravity for us. We finished with what’s considered the hottest topic in theoretical astrophysics. Jim is an extraordinary teacher and science communicator, so tune in and get your science hat on!

Science Fiction Author Darren Beyer (#2) - TMO Background Mode Interview

Darren Beyer is a former NASA Space Shuttle engineer at Kennedy Space Center who worked on launching and recovering more than a dozen missions. He also conducted astronaut training and had the honor of working onboard every Space Shuttle orbiter except Challenger. In late 1998, he left NASA to become an author.

The result was the Anghazi series of novels, Casimir Bridge, released in 2016 to rave reviews thanks largely to his commitment to putting the science back in science fiction. The second installment, Pathogen Protocol was released in October, 2018. In this second show with Darren, we continue our previous discussion: Back to the Moon first or off to Mars first? With robot companions? Industrializing the Moon. Plus: Darren’s approach to the third novel in the Anghazi series and an explanation of how his characters achieve interstellar travel.

Director, Vatican Observatory Br. Guy Consolmagno - TMO Background Mode Interview

Br. Guy Consolmagno earned his Bachelor’s and Master’s degrees in Planetary Science from MIT and his Ph.D. in Planetary Science from the University of Arizona. He’s been at the Vatican Observatory since 1993 and is currently the director there where his research explores connections between meteorites, asteroids, and the evolution of small solar system bodies. Br. Guy has co-authored two astronomy books as well as popular books such as Would you Baptize and Extraterrestrial?” He is a Jesuit Brother.

We chatted about Br. Guy’s post-graduate work, how he came to be at the Vatican Observatory—and then become the director. He explained why the Vatican has an observatory and how the Catholic Church is not anti-science. Actually he is just part of the Pontifical Academy of Sciences that advises the Pope. And there was much, much more.

Mike Bombich is the founder and president of Bombich Software, the developer of Carbon Copy Cloner. That’s a backup app for the Mac that has saved the day for many users. He’s a former Apple employee.

In this timely post-WWDC show, Mike joins me to explain the structure of APFS drives and the new read-only System files in macOS Catalina. He explained new features of volumes in macOS 10.15, especially how the System is isolated from the Data volume (which contains /Users).

Finally, Mike explained how Carbon Copy Cloner external drives can no longer be HFS+ in Catalina but must become APFS.
