When it says "serious scientific," it really goes for it. My eyes glazed over at all the numbers and metric measurements. It's definitely thorough, and some readers might appreciate the motto, "If it's worth doing, it's worth overdoing," as some answers were taken to a exhaustingly exhaustive level. I did appreciate learning a handful of new facts, but a lot of it was over my head. I was entertained and even giggled often (over a science book!), but will I retain any of it?
