Query: Not bad book with one major flaw

Much of the book is nicely done. The illustrations are most agreeable. The proofs, thoughnot quite on the level of selected proofs one finds in Wm. Dunham's "Journey through Genius"(available from Amazon), are OK. Not totally splendid, but OK, given the intended audience.What torpedos the little volume is the regrettable inanities on page 46, "Possible Impossibilities".What an unfortunate set of assertions! At least to me. So disturbing that there is no way I canplace this slim volume next to my four excellent Dunham books (all purchased from Amazon.All reviewed by me elsewhere.)I am returning the book to Amazon.Naf Los Altos CA
