Question: Unsuitable for undergraduates . The original Mechanical Engineering Design book written by Joseph Shigley, and later, with Larry Mitchell, was an excellent undergraduate text; it was readable at the introductory level, and it contained enough information and methodology for use as a good reference book after graduation. Unfortunately, this revised text, which was rewritten by Charles Mischke, is thoroughly unreadable, obfuscating, and is totally unsuitable as a text for undergraduate mechanical engineering students. The book is full of nuances, subtleties and informative data that do make it useful as a reference book on the shelf of an experienced design engineer, but not as a text for students learning the subject. For those who plan to teach a course for mechanical engineering majors on this topic, I recommend other texts such a Jack Collins' Mechanical Design of Machine Elements and Machines, Wiley, 2003

Answer: NEG

Question: Writer is a cad . I expected this book to be fun take on the Hollywood nanny experience where the reader can peek at the "other side" and perhaps try to guess who might be the real people behind the pseudonyms. Nope. Susanne Hansen is a cad who betrays her former employers (and her nanny friends' employers) by exposing their private family dynamics for entertainment and ridicule. It would have been much, MUCH better had she changed names and focused more on the celebrity lifestyle gossipy end of it than in her own boring self-examinations and snotty judgements. In every page she obsesses over wealth and then condemns the very people whose assets she admires. She seems to think that shallow and neglectful parenting is something only to be found in the nanny-hiring set. There was no joy in reading this book once I realized that while she may have changed the children's names, the names of the parents were quite real. It puts the lie to how much she felt for her charges that she would so humiliate their parents in pursuit of the almighty dollar

Answer: NEG

Question: Historical fiction at its very best. . Though this is a long read (not to be undertaken in one sitting---at least by those without some background in the region/culture) it is well worth it should you wish to cultivate an understanding of Russia & Eastern Europe. The novel is very true to historical detail, and although many of its characters are of course fictionalized, Rutherford has clearly gone to painstaking lengths to remain historically correct---far moreso than most "historical" novels. Reading "Russka" will leave you with a true sense of a people and how they have evolved historically & culturally over the span of centuries. I am a professor & I used this book with one of my classes as assigned reading, with sections of "Russka" paired with corresponding sections of a Russian history book with truly wonderful results---rather than griping about the reading load as usual, most students loved the book and via the novel & the pairing with the text, they seemed to learn a great deal. Addendum (Feb 16). Those folks who have criticised the book should perhaps view the book in the right light. It is not intended to be nor should it be used as a text book or scholarly treatise---though it would be a wonderful and creative suppliment for the latter. It is a very well crafted and meticulously well researched historical NOVEL and in accuracy of detail it is far superior to most (e.g. some of Michener's "historical" novels contain egregious innacuracies
