Yeah, historic novel authors and science fiction authors need to be on their toes and it's pretty funny if they aren't. This example - ugh. Why did they set it in the period if they were clearly not interested enough in it to do the most basic research on how things worked...? Because of the pretty clothes? I'm so curious I'll try to hunt down these books in the library.

I wonder why people don't bother with their details. When I was fifteen I read up on the basics of largely self-sufficient farming to keep a "lone mentor figure in the woods"-character from starving and ended up having whole paragraphs on him getting on with his harvest, which was probably too much detail - but I kept wondering how Yoda managed.
