Fics like Mary Sue Does Science

A genius from the Dark Age of Technology gets teleported to 30k and fixes all sorts of shenanigans through the power of SCIENCE. Lots of techno gibberish. Not only science fiction but also fictional science. You have been warned. I don't know if this counts as AU but there are some canon-divergent background settings and timeline alterations. There is some romance but it's mostly not about romance.
