Query: muddled thinking and weak presentation

As a mathematician with no biology backgroundwho needed to quickly learn somebasic facts in the field, I was hoping a 'for dummies' book wouldbe a quick and worthwhile read.I was anticipating that the book would be at the freshman collegelevel. When I received the book, it was clear (from the introduction)that it was intended for a high school audience. Moreover, thepresentation of basic physics concepts as they apply inbiology --- e.g. osmosis --- was so dumbed down and muddled asto actually be incomprehensible to me. Finally, the author triesto make up for poor presentation of the material with frequent humorwhich unfortunately is not actually funny and further distracts thereader. This book was very disappointing and of no use to me.
