I don't know. I'm afraid I expected a somewhat different kind of book when I requested it. I suppose I thought it would focus more on the show and give some more insights into it, but instead the show is used as a way to fix all the subjects addressed in this book together.
And as an introduction into these scientific subjects it's not bad. It's as they say 'explanations that even Penny would understand' and she might do now, but I'm pretty sure she would not have understood a lot of it at the beginning of the series. As a scientist myself I found there wasn't a lot of new things for me. Most of it I'd already seen in classes and besides physics isn't my main interest field in science.
The writing was okay, but the author tried to make a lot of jokes that didn't always quite land. It's probably just me, but it got a bit annoying after a while. And as this book clocks in at over 400 pages, it has to be something you must like, I guess...
So, if you're looking for a book about the show, keep looking, for besides some jokes and the search for where Sheldon's and Leonard 's apartment is there isn't much about it.
Thanks to the publisher and Netgalley for providing me with a free copy of this book in exchange for an honest review!
