Happy Columbus day! I just wanted to take a moment to note that Ian Maxfield over at The Catholic Laboratory is doing a wonderful series of podcasts on the history of European exploration in the 15th century, beginning with episode 45. Episodes can be found at the site above or on iTunes.
If you are interested in the roles of science and faith in the "Age of Exploration" this is quite an interesting series. If you are interested in science and faith in general, I recommend the entire podcast series. Physics, chemistry, biology, geology - you name it. From evolution to parallel universes, Ian covers a broad range of topics from a Catholic perspective, often with a really bad joke thrown in.
