| Sep 9, 2013 at 8:55 | comment | added | Niemi | To explain the Yoneda Lemma to undergraduates, you need to introduce the concept of a category, that of a functor, and that of a natural transformation (unless that is taught in an undergraduate course, but if it is, then the Yoneda Lemma is probably taught in that course, too). Then you can start working on the lemma. I don't see how this can reasonably done within 30 minutes, in particular because just giving definitions does not given the students any intuition. | |

| Apr 5, 2011 at 11:38 | comment | added | Todd Trimble | I also considered the Yoneda lemma, but I think it's a tricky case. To me the Yoneda lemma is just about the deepest "triviality" (if that isn't too self-contradictory!) in all of mathematics, but I think its profound significance takes quite some time to sink in, and it's not so easy to get that across in 30 minutes (I don't think). | |
