I have kept up with the 'Annals of Improbable Research' for several years, and must say that this book reflects the best of the highbrow, yet offbeat sense of humor found in 'AIR'.
For those unfamiliar, the Ig Nobel prizes are awarded every year for "achievements that cannot or should not be reproduced" in an elaborate spectacle of a ceremony at Harvard University. Among the participants are many genuine Nobel Prize winners, proving beyond doubt that scientists do have a sense of humor.
There is something for everyone in this book, even for those who hate science; in fact especially for those who hate science. The subjects coast gracefully from the bizarre ("Elevator Music Prevents the Common Cold") to the absolute fringe of science ("The Effects of Ale, Garlic, and Soured Cream on the Appetites of Leeches"; the sour cream was the biggest appetite stimulant, by the way). There are subjects you would have never thought of (unless you are a scientist with way too much time and Federal grant money on your hands) from levitating frogs to "Chicken Plucking as Measure of Tornado Wind Speed". The subject matter is dizzying and amusing.
I eventually settled on a four star rating for a couple of reasons. First, in a majority of cases, these studies are supported through tax dollars, and I generally resent the glorification of wasted money, which this book surely is in great, if unintentional, part (only a small percentage of these studies have genuine follow on benefits; most were clearly done for square-filling publication in the 'publish or perish' world of academia). Second, the politically motivated selection of some recipients, notably Edward Teller, is an undeserved slap at scientists who did and do work on defense projects (where a huge number of genuine scientific advances actually occur) by what is an obviously smug class of academics, who clearly seek to advance their own political agenda. I find that to have tarnished what would have otherwise been a superior work of science reporting and humor.
Despite my reservations, I overall recommend the book, as it does generally meet its stated goals of making a person laugh and think.
