This week I'm back to basics with an old friend, Dr. Arnold Heiser, Professor Emeritus of Astronomy at Vanderbilt University's Dyer Observatory. Dr. Heiser, former director of the observatory, may be retired; but he still hauls himself up to the quiet, arboreal environs of Dyer every workday to continue his research into stellar clusters and their associations and pulsating variable stars. In addition, Arnie regularly creates and delivers IVC (interactive videoconferencing) sessions with K12 classrooms worldwide, via the Center for Science Outreach's "Virtual Scientists in the Classroom" program. We had a nice chat and recorded it using Skype's "call in" feature and HotRecorder, a third-party program that does a nice job of audio capture. The resulting audio is a little noisy, but in an interesting way, I think: I for one sorta like the telephone-like sound quality. Hope you do, too. Feel free to comment here if you have your own opinion... Listen to Arnie's chat here, or click on the "Feeds" button in the left-hand sidebar to browse all past episodes of our li'l show. Music today fea!tures Israeli musician Guy David's composition, "Airwaves." Check out his work at the Podsafe Music Network! I like this piece so much I just let it play on out at the end. Fun stuff!!!
