David Reffkin is a radio host at KUSF in San Francisco. His usual gig is classical music, but once a month he hosts a special called Static Limit where he delves into physics and cosmology. Here's an interview he did with me a short while back. Right at the beginning we're talking about this very blog, which I am now using to plug the interview, which is mostly about my book. This is what's known as "synergy." (Those viewing in an RSS reader, you have to visit the page to click the audio link.)
David assumes the listeners have been following along previous shows, so we don't spend too much time defining general relativity and the Big Bang; we go right for the cutting edge. But we also covered a lot of meta ground, about the process of doing physics. He also gave me the most comprehensive list of errata (mostly minor typos) for my book, so I know he read the whole thing!
