Currently I'm listening to is sports related stuff, so I'm looking to branch out for some new material during my jogging, commuting, etc. Math, science, then philosophy would be the order of my preference, but anything is better than nothing.
Thanks, I'll check out Philosopher's Zone. Doing a couple searches, I've found:
NOVA PBS has a podcast.
There seem to be a few skeptic type podcast, like Skeptics Guide which is a panel of brothers who mock crazy people.
I just subscribed to Mathgrad podcast, but I haven't listened to any yet. Seems too short.
There's a Scientific American podcast.
NPR also has Science Friday.
I'm not sure what's good or not, and often there's a hidden gem which I could miss searching. I'd appreciate any input.
