Thanks for the recommendation! It seems I will enjoy it; it belongs in the same theme as Mark Twain's novel, only it's not humorous.
On that note, Wikipedia took me to "The Man Who Came Early" by Poul Anderson, which fits what I'm saying exactly: a modern day man is taken back to Viking-age Iceland, where his knowledge fails him catastrophically as he is unable to explain it or put it into practice, to disastrous results.
