[EX Q]: Knocked-up Ebony Mamas . Wittgenstein said that the purpose of a popularization is to make people think they understand something they don't understand. What seems to be a common current of science popularizations is that they "explain" things in such a simplified way that the reader who actually wants to get down to brass tacks is completely mystified. Einstein's book on relativity is a case in point, as is this book in which the candid reader is informed that "Objects at rest tend to remain at rest, therefore heavier objects will fall faster in a gravitational field." Got that? If so, maybe you can explain it to me. Listen, I know something about Physics. Back in the seventies I built a particle accelerator out of a blow drier and a box of Mike and Ikes.

[EX Q]: 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

[EX Q]: Don't waste your money... . ...you can waste your time and save your money by checking this out of your local library. If you want to get an "inside view" of the inner workings of Wall Street during the excessive gyrations of the '80s, then read Den of Theives - that book is well written and well worth the money! What turned me off about this book was the structure and the writing style. The first half of the book was essentially the author relating fortuitous circumstances that were the product of Serendipity. He was simply in the right place at the right time, had virutally no idea how he got there, felt out of place the whole time (even when he was raking in the Big Bucks in NY and London), and so now he thought he'd wwrite a book about it. I also got the sense that he was trying to assuage some guilt from his association at Salomon Brothers. He was there, he made a lot of money, good for him - get over it! I was also pretty disappointed because the subject matter has A LOT more potential. I might have actually enjoyed it - had I not read Den of Theives 7 years earlier, and already had some idea of how things took place. But, if you can get it for $5 or less (including shipping), and you have little to no knowledge of what an investment banker's life is like (and you haven't also seen the movie Wall Street (which covers the same highlights in this book)), then it's probably worth it. I did like the wrap up he did towards the end of the book, relating where he had heard everyone from the firm ended up...althought that seemed a little rushed..
