[Q]: lack of examples and horrible explanations make a ghastly diffE text . Because the guy who initiated the project of writing the book is here at Rice, the rest of us are unlucky enough to have to use this book. If your class uses this book, prepare to go to class. All the time. That's because if you fall behind, the book does not do a good job of explaining things to you. Examples are generally vague and only apply to a few types of problems provided at the back of each section. A lot of the time, I'd find myself stumped on a problem, looking back, and realizing there was no example problem for me to get ideas from.    Yes there are lots of problems and that's good, in a way. But what's the point of having all those problems if the book never teaches you how to do them?    Furthermore, it is a poorly written book. Generally, reading through the book is like searching for a needle in a haystack. Literally speaking. You spend all that time figuring out what the authors talk about and once you figure it out, it was not even worth all that time.    So go to class. All the time. If the prof isnt that great, get yourself another workbook. I havent seen Schaum's but I'm pretty sure they'll do a better job on covering the topics than this text does

[Q]: Brilliant Thud memoire . The F-105 is a most fascinating aircraft. A superb cold-war design; it was meant to be a sort of man-guided supersonic cruise missile for delivery of nuclear weapons to tactical targets in the european theater. It was, of course, never used for this purpose, but was instead put to a use in the air war over Vietnam. The Thud was never meant to be a precision dive bomber, or to pass through heavily defended areas at subsonic speeds. All the same, politicians dictated this use (and of course went looking for someone besides themselves to blame when their "top fighter-bomber" started getting shot down in heroic quantity; so many were shot down, there weren't enough seasoned men to continue to fly them. They were shot down in so many myriads, fresh out of pilot school fighter-bomber jocks, or long grounded middle-aged desk jockies would be put directly into combat (where they would often be shot down).    The men who flew this jet were, as the cliche goes, a special breed of heroes. Unlike, say, fighter pilots or B-52 pilots, they faced almost certain death, or horrible imprisonment. Their survival rate was comparable to that of the B-17 tailgunner over Germany in WW-2; very low indeed. Oftentimes their missions were secret in nature, so the government couldn't even acknowledge that the Thud had been shot down and work for the release of the pilot.    Major Rasimus' memoire takes place at a crucial escalation in the war; in 1966. The Johnson administration decided to escalate the war by "sending messages" to the North Vietnamese via the use of bombing as a psychological and diplomatic tool. The hare-brained scheme was that, by bombing one thing, and not another, the NVA would be trained, like a pet dog is trained with a rolled up newspaper. The idea was ridiculous, and of course didn't work.     Rasimus was one of those unsung heroes who, fresh out of pilot school, grew enormous handlebar moustaches to protect them from evil on their impossible missions. He tells the tales of the base dog, Roscoe, and of various of his team, and those who came after. You can practically smell the oil on the tarmac, and the blackpowder charges which combat-started the '105's engines. While americans would rather forget the war in Vietnam, I can't forget the courage of these men who fought in these insane supersonic contraptions. May their spirit inspire a new generation of warriors. Thanks Ed; for your service and your great book
