Maybe there is a "for dummies" or "idiots guide" that will work?
I was thinking about that, but I don't know how reliable they are when it comes to science. Plus, I can't seem to find a general version, although they have several individual fields of study.
Edited to add
: I did find an "Idiot's Guide to the Science of Everything". While it seems okay, I'm more interested in another book I saw while I was searching B&N by an author named Bill Bryson, entitled, "A Short History of Nearly Everything".
