Our Mathematical Universe is nothing if not impressive. Brilliantly argued and beautifully written, it is never less than thought-provoking about the greatest mysteries of our existence (New York Times)

An amazing ride through the rich landscape of contemporary cosmology... Physics could do with more characters like Tegmark... an imaginative intellect and a charismatic presence (Clive Cookson Financial Times)

Tegmark is one of the rock gods of cosmology, a select group of thinkers who are using their mathematical prowess to tear up all our cherished notions about the universe, and replace it with a cosmos that is so bewilderingly weird that it makes the plot of most science-fiction novels look like an Ikea instruction leaflet (Telegraph)

Our Mathematical Universe boldly confronts one of the deepest questions: why is mathematics so spectacularly successful at describing the cosmos? Through lively writing and wonderfully accessible explanations, Max Tegmark - one of the world's leading theoretical physicists - guides the reader to a possible answer, and reveals how, if it's right, our understanding of reality itself would be radically altered (Brian Greene)
