Chad Orzel creates very interesting mix tapes, and has a much greater knowledge of both physics and pop music than I could ever attain. But the reason I am writing this post is to point out a debate between him and Brad DeLong. This is a subtle debate, in that Brad makes a point, Chad calls him a heretic, the end. So, whose version of "Like a Rolling Stone" is better, Dylan's or Mellencamp's?
