Podcasting

I took a look at Podcast Pickle. Just by searching "math" I see a ton of different people whose podcasts relate to math. Then in each one you find many more. I don't like that you cannot link directly to a specific users channel or podcasts. Two that I found where interesting were Mathgrad.com that talks about everyday math, and Math factor which looks at math puzzles and brain teasers. I really enjoyed the one that talks about zero, I would use this in my class, and I think just by listen to a podcast about students are more likely to remember zero is not positive or negative 'I remember that from the podcast'. I love to use brain teasers with my students whenever we have a few extra minutes.
