Dr. Ed Burger calls his "Effective Thinking and Creative Puzzle-Solving" class at Southwestern University in Georgetown, Texas, the "Seinfeld" of classes. Why? Burger claims that class is about nothing, which was a popular knock against the 1990's t-v show. What does he mean by that? In this episode of KUT's podcast "Higher Ed," Burger and KUT's Jennifer Stayton discuss the utility of working through tricky puzzlers, and why the class that lacks any short-term, tangible content may actually have quite a bit to teach in the long run.
