Make no mistake, this is a well written, easy to read and understand book on some of the major paradoxes (the clue is in the title) in science. The problem is that anyone who has picked up any of the popular science books published in the past 5 years or so will be very familiar with many if not most of these. So the question is, did this book need to be written? Probably yes. I think Prof Al-Khalli gets away with it because the book is written in such a very accessible way and even if you are aware of much of the content this book will still illuminate and entertain so is probably worth the investment. Of course if you haven't read any popular science books in the past 5 years then this may all be new to you so you should definitely read the book.
