interesting but made my brain hurt - multiple views of the universe, bubble universes, linear models of the universe, expansion, true infinity, it was both mind expanding (if infinity is real, then there are infinite universes, if the number of particles is finite and n then there must be n+1 universes  and therefore there must be duplicates. If there are dumplicartes then they are identical in all respects therefore must be more than 1 of you. This reminds me of what I thought infinity meant when I was a kid. 

This was like the book of the metre but simpler. A survey of all the units and kinds of measurement. Easy to read, and a coffee table chapter length.

This was a good one - the lives of the mathematicians, including all the good stories like Galois.
