Math!John

[atheniatrue.livejournal.com]

I was re-reading an EOD AU with Mathematician!John Sheppard (one of Keira Marcos'stories) and it put me in the mood for more stories where John shows off his math skills. They don't have to be AU's where John got his Ph.D or went to Atlantis as a scientist (though those are welcome too). They can simply be stories where he shows off his intellectual side more.
(For instance, I have read one where his team is on some planet working with local scientists and they are looking at these street lights that are powered strangely. It triggers John and he ends up developing a whole new type of naquadah generator. The whole thing is still in canon!Sheppard, but he is just more mathy.)

For AUs, I would prefer non-Rod! AUs - or at least ones that don't start immediately after the switch. I tend to like ones that are either (sort of) in canon or completely removed from the canon universe(that is, ones that don't show multiverse crossovers).

Thanks.
