I got this as a christmas present from Katherine's mum, which was nice of her. It's not the kind of thing I would usually buy for myself but it is something I will happily read. Sabbagh collects a variety of interesting anecdotes, research articles, strange facts and odd stories encompassing some of the main scientific divisions.
In some ways it feels like a compilation of newspaper articles (perhaps a weekly 'odd-science' column). As such it's easy to dip it and out of and usually entertaining, albeit brief. There's a lot to interest though occasionally frustrating in how little detail or exploration of a topic is given (plus there's no easy way to check on his sources other than visiting his website).
It did lead to a realisation though. After understanding most of the astrophysics chapter, little of the maths, and all of the biology (playing to my strengths), I got to the medical section and realised most of the tales were remarkably basic in what they talked about and indeed somewhat patronising at times. Extrapolating this to the other chapters it made me wonder whether that's the case for all of them and ultimately the entire book is rather superficial, pandering to the stupidity of the layperson. Hmmm.
I suspect it doesn't matter as I enjoyed it anyway and have taken to annoying people by reciting the stranger aspects of science that amused me.
P.s. this isn't the edition I have (which is a horrible cover) but they don't list mine on GRs.
