Parts of this book went over my head, but I still enjoyed it alot. It is a love letter to science and curiousity, answering questions I never knew I had.

My one problem with this book is the "weird and worrying questions"-sections, as it at times points fun at the questions, and other times just serve as unanswered interesting questions. Where is the fun in that?

I ended up getting the UK version of this, which had a fun preface explaining its use of units. I still would have preferred the metric system.
