Having been working on similar approaches to studies of the universe, and mind, I found this book pretty comprehensive without being too heavy or technical. The chatty narrative and easy-going linkage of several quite obscure and difficult propositions makes for clear engagement of the writer with the amateur scientific reader so that one feels a kind of familial, personal relationship with Max Tegmark a teacher 'par excellence'!
His exposition is lucid enough to bring one to that sense of awe and wonderment of the fantastic significance of what he is at pains to excuse - quite unnecessarily in my opinion - for, what he has to teach us is profound education indeed and well worth our while to take heed of the enormity of his theory.
This work, in my opinion, is one major advance in the knowledge of the mechanisms that underlie our world, the cosmos and life itself, from the DNA to furthest stars - but more importantly still - to the fundamental depths of the human mind, the nature of consciousness, and the coming to terms with the Infinite, the paradox of Schroedinger's findings, and the realisation that we are on the verge of the charting of destiny and a deeper understanding of the nature of humanity vis-a-vis the entire cosmos.
Now we can learn where our thoughts are - when we are not thinking them!
