I listen rather than read on train journeys as I can't stand being jostled by other travelers, and walking & listening is so easy
While this book is interesting, quite a lot of it is just "filler" to make the book larger - the constant wandering off subject, the fact that some of them don't NEED to make sense (Quantum Physics for one), and the amount of background unrelated information that's given just gets boring at times
The book should have been done as an abridged version to trim out the fat, because the book itself just has a lot of wasted stuff that you just don't need to know, or is interesting but overall unrelated to the main topic
If you have a spare credit and want something that is full of information, but you'll probably only ever listen to once, this is the book for you - I found myself listening while doing other things, so it was like background noise rather than something I'd concentrate on
This is an excellent book, but the audio version read by Steve West is a let down. The publishers should know better (by now), in compiling audio books, just reading very fast (so that it can finish quickly -- why is the hurry) does not work well. Steve West's reading is like a running train (each compartment (i.e. sentence) seem to wobble in between and raises and plonk with the next. As the concepts described in the book needs understanding (i.e. putting together in mind analytically with the previously assimilated hard facts). So the running train with um-ha-ha would not help. I strongly suggest to buy the printed version of the book instead of this audio version.
