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:
Not badly written, but ultimately preposterous . Toward the end of this novel, the lead character, Reichs' usual heroine Tempe Brennan, remarks on the "remarkable coincidence" of one of the plot points. By this point in the book, this is like pointing out to a rabid dog that it's got some spittle on its chin.  This book relies on coincidence so fundamentally that if it were removed, it would fall into 3 or 4 different books with little or nothing to do with one another.    Reichs is not a bad writer, and for someone who so clearly comes from a forensic background, is passably adept at character, plot and scene setting. She knows how to build suspense and intrigue, and never lets the technicalities of her lead character's profession -- a forensic anthropologist -- or the intricacies of her work, undermine the story.    This book centres on Brennan's investigation of a religious cult that perpetrates a set of murders. There are lots of interesting points about how cults work, ritual murder and even large group awareness programs get in on the action. And, of course, several forensic investigations where we are treated to the processes of digging up bones, collecting maggots and bugs, and examining various grim bits of the human body.    What undermines this book is that the first half is at least three different, unrelated stories; and the second is such a clumsy and outrageous merging of them into one, that one drifts from disinterest to incredulity. The jacket cover says this book is about the excavation of a 19th century nun's bones, and the mysteries therewith. In fact, this is just story number 1, which is of only tangential importance to the ultimate, main storyline.    It is not obvious, even in terms of the world of Death du Jour, why Reichs needed all this intermingling. It feels like she started writing a travel journal, then stuck a murder into each of her ports of call, then simply declared that they all belong to the same overarching plot. In this context, each individual story feels derivative, and the grand plot feels like a desperate trick.    A well-written and, at times, interesting book, which is ultimately unsatisfying and preposterous
answer:
NEG
