I actually want that... but don't do extra work because I ask nicely -- I will gladly pay for an (e)book on this topic, if it was written at a "smart layman"'s level. I think its fascinating, but not career fascinating, if you know what I mean. I just want to read about these things and maybe be able to impress strangers with random facts that were well researched by some person who knows what he's talking about.
