Of course; it's a common thought-experiment among geeks, ever since A Connecticut Yankee. There's even a shirt stuffed with technical info in case one ever goes back in time.
(FWIW, I think you'd do better with conceptual stuff like Descartes and gravity, which you can explain to the local savant and work on hammering out the details together; metallurgy is hard, and it's not like there weren't steam engines before the industrial revolution - they were just uselessly weak and expensive. Low cost of labor means machines are too expensive to be worth bothering with.)
You're probably right, but other than proving the Earth is round (which is not likely to need proving unless I go far back), there's not a lot of useful things I can demonstrate to the savant. And telling the savant about germ theory or suchlike without being able to demonstrate it seems pretty useless to me.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
If continuing the discussion becomes impractical, that means you win at open threads; a celebratory top-level post on the topic is traditional.
