In this collection of writings, the logbook of an intelligence always on the move, Carlo Rovelli follows his curiosity and invites us on a voyage through science, history, philosophy and politics.Written with his usual clarity and wit, these pieces range widely across time and space: from Newton's alchemy to Einstein's mistakes, from Nabokov's butterflies to Dante's cosmology, from travels in Africa to the consciousness of an octopus, from mind-altering psychedelic substances to the meaning of atheism.Charming, pithy and elegant, this book is the perfect gateway to the universe of one of the most influential scientists of our age.
