"Professors making their mark in 'orbit structure of diffeomorphims of manifolds' feel their talents would be wasted teaching Math 101. But they might mull Albert Einstein's words to young researchers: 'You do not really understand something unless you can explain it to your grandmother.'"

Granting that a necessary condition for understanding X is being able to explain X to your grandma (what if you have an exceptionally stupid grandma?) it hardly follows that if you don't

**want**to explain X to your grandma, you don't understand X. Anyway, math professors were once grad students who almost certainly paid their dues by teaching Math 101, or the equivalent. The suggestion that not wanting to do it now means they don't understand elementary mathematics is ludicrous.Rudy Garns originally shared:

Radical Alteration Alert! "The liberal arts have been radically altered, both in format and function. The catalog labels are still recognizable: psychology, comparative literature, English and the like. But what is being taught is no longer attuned to undergraduates looking for a broader and deeper understanding of the world."

Is each class supposed to provide "a broader and deeper understanding" or might that be the desired cumulative effect of taking lots of college classes?
