Why didn’t they have this class at my college? (Probably because I went to a tiny liberal-arts school that mainly offered classes like “Examining Limits in Newton’s Principia”.)  Anyhoo.  At the University of California at Irvine, students can take way-cool professor Michael Dennin’s seminar analyzing the feasibility of the precepts behind, say,  Bruce Wayne’s bat belt. But don’t get too jealous of those snot-nosed freshmen. You can order the textbook for the course, by Lois Gresh and Robert Weinberg, on Amazon. —Megan Miller
