4.0

Rovelli's subtitle is apt, he does take us on a journey, one I enjoyed thoroughly. This is a journey in four parts. The first two bring the lay-reader up to speed with "what is known", so that the author can then dig into what he really lives for, to explain and open up what he has learned and suspects about the quantum reality. Parts three and four is where he takes us down this particular rabbit hole, and it is quite the ride.

I enjoyed the daily reading/thinking/struggle with trying to grasp, imagine and absorb what he was showing me. No math was required but imagination and willingness to go on this journey surely are required. Some of what he has to say will be difficult to understand and sometimes I was so aware that I was not getting it that I would get distracted with my own revealed ignorance, but really this is fine, this is not easy stuff and the fun of a roller coaster is the little feeling of panic as you look over the edge.

I recommend this book to anyone who wants to be introduced to the reality in which we live.
