Why Can't Elephants Jump? and 113 Other Tantalizing Science Questions Answered by Mick O'HareTrivia
This is the third book in a series by the editors at New Scientist magazine. The magazine is divided into sections and is answered by a variety of people--some questions have many answers and it's almost like following blog posts on the computer.
It is unclear who is answering some of the questions---researchers, scientists or general readers. It seems more like random readers of their blog so I'm not sure how much credibility I can give to their answers and many answers seem to even contradict one another.
Anyone who reads trivia bokks (and this is just one trivia tidbit after another) know the pitfalls and pleasures of reading this genre. It is a book to read over time, not one to read at one sitting. Pick it up and put it down at your leisure. Overall, interesting scientific questions; questionable answers.
