I loved this book. I didn't know before reading the book anything that was discussed in its pages. The author, Paul Hoffman, does a fantastic job of introducing new topics, while still providing in depth information on the matter. I felt also that the topics were not exhaustive to the point of being boring, but that they were switched up often enough to maintain a constant desire to read more.

I did not give this book a perfect 5 because some of the topics are outdated, especially with regards to computers.

Overall I would suggest this book to anyone who likes history, engineering, or mathematics in that order.
