So, complaint first: I watched the video version of this about ten years ago, and I naively assumed that this audio book version would be adapted for listening, not viewing. Not so. This is literally just the audio from the video. No more, no less. What this means is that Professor Wolfson often talks about things that he assumes the viewer is looking at, but which of course you can't see. There's a feeble suggestion to refer to visual aids that come with the audiobook. I don't know where these visual aids are or where to find them, and in any case, I am often doing things while I listen to audio books like dishes or driving. It's better to watch this as a video rather than listen to it as an audiobook.
Now despite that, I still enjoyed it. Most of the time you can understand what the Professor is describing, and I found it a very clear and interesting introduction to modern physics.
