I’d wanted to read this for ages and got it for Christmas – it was shorted than expected, at around 50 pages, but also a much higher intellectual level than I expected.
My main issue is that I didn’t really understand one of the concepts that was used a LOT in the text. If there had been an extra page or two near the start to explain it a bit more, I think I could have loved it. It was talking about musical note differences in terms of ratios, so if anyone who’s into both music and physics can help me understand that a bit more, I’d then happily give it a re-read!
Either way, I was still able to follow bits of it, and they were interesting and also pretty!

Anything to add...?
