The first few chapters cover the history of how we think about time and our efforts to measure it based on natural phenomena. Interesting, but not much that I haven't read about before. This is followed by a more philosophical view of time and how our mind deals with time. I find it difficult to decide whether this section is too long, too laboured or, on the contrary, more space should have been devoted to fully explain the ideas. Next we reach the largest segment of the book that looks at time from the scientific viewpoint, particularly how Einstein's theory of relativity clashes with our subjective perception of time. The final chapter returns to philosophy and is, thankfully, short.
The large number of examples actually get in the way and could be better handled in a digital form of the book with hypertext links.
