| Dec 6, 2009 at 0:35 | comment | added | Harrison Brown | @Scott/Ben: Speaking for myself, I voted up Jose's answer precisely because as written it would be confusing. That and because it's always lots of fun to sneak in some general nonsense when teaching a general audience. (Agree that it's off-topic in general, though.) | |
| Dec 5, 2009 at 21:09 | comment | added | Anton Geraschenko | I don't think this question belongs on Math Overflow. Let's keep to questions so that you should be a mathematician to give a competent answer, rather than a neuroscientist or developmental psychologist. | |

| Dec 5, 2009 at 21:02 | comment | added | José Figueroa-O'Farrill | @Ben: Quite possibly if explained as written. However the answer is meant for the person doing the teaching. This is why I edited it to state explicitly that my answer should be translated into a suitable narrative, perhaps via analogies as in the answers inspired by "finance". | |

| Dec 5, 2009 at 20:32 | comment | added | Kim Morrison | What's going on here? This is a barely-appropriate question on mathoverflow (I'd vote to close if I weren't a moderator). But people are voting up the answers like crazy! I think this is a great example of how easy material gets lots of votes, but the hard and interesting stuff that we're actually after wallows in obscurity. | |
