This book took so many tangents into unrelated topics that I couldn't wade through all the extras, and didn't finish the book. The pretentious writing annoyed me. The author adds in anecdotes about Aristotle and Nietzsche just so he can sound intelligent for knowing anecdotes about Aristotle and Nietzsche.

This book could have been much shorter if the writing would just stick to the main topic. I don't need to read a chapter on the entire history of clocks to know that the invention of the clock changed how society viewed time. A couple of paragraphs would have sufficed.

I was really disappointed in how the information was laid out in this book. It's not organized very well, and jumps between various topics that are barely related to the main subject material.
