I looked at a few of Norbert Weiner's books, but they weren't easy reading. The first started out on transformation properties of Abelian groups, as I remember. Shannon's 'Information Theory' is a bit easier, and I still have my copy of the original 1954 edition. The hitch is it's all about communication of messages, and ways to code them that minimizes the chances of noise distorting the messages, and has nothing to do with what an intelligent layman would call information. It paved the way to checking that's done here and on computer files by doing such things as cyclic redundancy checks, and such.
