Math/Maths Podcast: I love listening to this podcast. Samuel Hansen and Peter Rowlett inspired me with their sometimes serious, sometimes to begin telling people “I want to be a mathematical podcaster.” Because that sounds ridiculously cool. (:
The podcast is no longer running, but the archive of 127 episodes at an hour in length each should keep you going for a while.
OrigamiSpirit.com: An origami blog I recently found! I am enjoying the new patterns I have found on the blog, as well as the commentary on paper folding.
