Well, one can take good advice about being careful with your fireballs in the phlogiston. Or, after the TPK, one might actually be interested to read up a bit about Stahl and Becher...."how does this work for people who don't know much about medieval science?"
On a more serious note, for me it was the other way around - SJ explains the mechanics of the setting in a good way, no prior knowledge necessary, but it got me interested to learn more about real world medieval science.
