Don Melton is probably best known as the person who started the Safari and WebKit projects at Apple and his rise to Apple Engineering Director of Internet Technologies. These days he’s an aspiring writer, podcaster and recovering programmer.

Don walks us through his early career starting with his aspiration to become a comic strip or comic book artist. His artistic talent led to a newspaper job which led to information graphics which led to work with Macs. His tinkering with the Mac revealed that he had a special talent for programming, and that ultimately led to his job at Netscape developing the Navigator browser. Later, a relationship with Andy Hertzfeld and Bud Tribble led to his job at Apple in 2001, chartered by Scott Forstall, to write a web browser. Don tells a fascinating story about the development of Safari for Mac OS X and the race to replace Microsoft’s Internet Explorer.

Dr. Brian Keating is an astrophysicist at the Center for Astrophysics and Space Sciences at the University of California, San Diego. His specialty is cosmology, and he is the father of the original BICEP project (Background Imaging of Cosmic Extragalactic Polarization). Last year, Brian published a terrific, courageous book about his team’s research, some life lessons, and the challenges of scientific research: Losing the Nobel Prize: A Story of Cosmology, Ambition, and the Perils of Science’s Highest Honor. It’s now out in paperback.

This time, we expanded on the discussion in his book about his quest for the Nobel prize. At the core: what the polarization of the cosmic background radiation tells us about the Big Bang. We also delved into the theory of the multiverse and its relationship to the anthropic principle. Finally, find out how you could win a piece of a 4.5 billion year old asteroid.
