@Dunboyer and @HydeSnark I count on you guys to introduce the incoming class to this old and apparently thriving UChicago tradition. There’s more to this matter than chemistry. Explain to them the somewhat existential connection between caffeine and thinking. Esthetics are also to be considered: There’s a proper way to grasp one’s mug - or Styrofoam cup - and pause between gulps so as to indicate you are pondering the big questions. Holding all other factors constant, I find no other way to account for the U of C’s pre-eminence!
