PositiveThe New York Times Book Review... Rovelli tackles both the quantum realm and the ways it helps us make sense of the mind with refreshing clarity and without hand-wavy mystery-mongering ... Rovelli’s writing, translated from Italian by Erica Segre and Simon Carnell, is simultaneously assured and humble. His erudition is evident, especially in his delightfully long segues into the kindred philosophies of Ernst Mach, Alexander Bogdanov (an early Bolshevik) and Nagarjuna ... poetic and spare. Readers unfamiliar with quantum physics may struggle to get its full import. To use his theory as a metaphor, Rovelli’s lyricism may depend on how many other, possibly plodding, nitty-gritty accounts of quantum physics one may have read: The more that number, the more Helgoland will seem a poem.
