The author seems knowledgeable in the area he covers, but, unfortunately, can't write: there isn't one clear paragraph in the whole book, not one coherent chapter — this book reads like a transcript of a mental patient's ranting: disjointed and random, ungrammatical, having no logical structure, no direction; with concepts used w/o being defined before (or after!); wrong words used all the time (or, alternatively, missing a word now and then) — all in all, a sizeable load of gibberish that's torture to parse and impossible to understand. Even vector math itself is not defined!

The author, if he must write at all, should team up with a competent technical writer, maybe as a coauthor, especially since the publisher, Wordware (based on my observations, a second-rate outfit in general) doesn't seem keen on providing adequate editorial contribution
