This podcast is, hands down, one of the best available on iTunes.
The variety of topics covered is fantastic, and somehow, the host manages to talk about everything awesome in life (deep sea diving, sailplanes, NASA, aerial refueling and autonomous flight systems, quantum physics, the list goes on and on...) while keeping it very interesting for the listener. Also, he is able to talk to the people at the head of the fields, who actually KNOW what they're talking about.
Also, I love the fact that things aren't dumbed down too much.
I learn more in these podcasts than I do in class!
Here's hoping he keeps it up for the future, this podcast deserves to be on the iTunes front page.
Tip for those subscribing to the podcast: download ALL the past episodes as well. They are goooood.
