I have quite a long commute on my way to my university (about 75 minutes) so I was wondering if there's a math-related podcast or something of the sort you'd recommend. Exercises are appreciated as well, but they should be conceptual (or at least light on computations, so I could solve them in my head), since I can't write while on my commute (I don't drive, but trains are awfully crowded here). Any other suggestion is welcome!

As a sidenote, I've taken multivariable calculus and elementary courses covering linear algebra, sequences and series, number theory and a little bit of complex analysis.

It'd be nice if an admin could CW this. – F M Oct 27 '11 at 21:38
(+1) Good question. While I was in grad school, I went to see my future wife just about every weekend. The drive was about 4 hours each way, my car had no CD player, and the radio didn't work well. Those drives were great times to work on proofs/homework. I would recommend re-reading homework problems or course notes just before the commute so you can ponder them while you travel. – Bill Cook Oct 27 '11 at 21:48
@Bill: That's what I'm currently doing; the thing is I'm taking multivariable calculus and an algebra course which is an introduction to a variety of topics, as combinatorics and number theory. So most exercises are a tad heavy on computations, as opposed to more abstract reasoning. It's nice to think about proofs to the theorems seen in class though. Thanks for your comment! – F M Oct 27 '11 at 21:51
@Fernando: I suggest you add a bit on your background, since suggestions like topology and such would be coming up eventually, you may want to somewhat set the focus on things you can actually do. – Asaf Karagila Oct 27 '11 at 22:07
You may want to add this to the post... :-) – Asaf Karagila Oct 27 '11 at 22:18

It's only ten episodes of 15 minutes each, so it won't last for long (just two commutes!). But as a stop-gap you can try Marcus du Satoy's A Brief History of Mathematics.

+1. This goes into my iPhone right away! – user17762 Oct 27 '11 at 21:48
Thanks! This is the kind of thing I was looking for. – F M Oct 27 '11 at 21:51
