When We Cease to Understand the World shows us great minds striking out into dangerous, uncharted terrain. Fritz Haber, Alexander Grothendieck, Werner Heisenberg, Erwin Schrödinger: these are among the luminaries into whose troubled minds we are thrust as they grapple with the most profound questions of existence. They have strokes of unparalleled genius, they alienate friends and lovers, they descend into isolated states of madness. Some of their discoveries revolutionise our world for the better; others pave the way to chaos and unimaginable suffering. The lines are never clear. With breakneck pace and wondrous detail, Benjamín Labatut uses the imaginative resources of fiction to break open the stories of scientists and mathematicians who expanded our notions of the possible.

"Ingenious, intricate and deeply disturbing... Labatut has written a dystopian nonfiction novel set not in the future but in the present" - Guardian

"We may be familiar with such things as Schrödinger's cat and Heisenberg's uncertainty principle... but the sheer audacity, the utter insanity of the ideas and the thinkers who discovered these ideas has never, in my experience, been so vividly and terrifyingly conveyed as in this short, monstrous, and brilliant book" - Philip Pullman

"Absolutely brilliant. I was utterly gripped and wolfed it down. It feels as if he had invented an entirely new genre" - Mark Haddon, author of 'The Porpoise'

"Labatut uses fiction to crack open the stories of scientists and mathematicians whose expanded our notions of the possible, while also presenting them as human, all too human" - Dazed

"I absolutely loved this. The writing crackles with energy. What a triumph. I hope it does really well and finds multitudinous readers" - Cathy Rentzenbrink, author of 'The Last Act of Love'

"A dazzling associative caper full of graceful arabesques linking continents and centuries and ideas" - Sunday Times

"Remind[s] us of fiction's power to take us to another world and expand our understanding of this one... When We Cease to Understand the World showcases the minds seeking to pierce the mysterious heart of mathematics" - Guardian

"Darkly dazzling... Given a fine, exacting translation from the Spanish by Adrian Nathan West, these pieces possess an insidiously persuasive power... this book-as haunting as it is erudite-stubbornly insists on connecting the wonders of scientific advancement to the atrocities of history" - Wall Street Journal

"The strangest and most original book I've read for years. It hovers in a state between fiction and non-fiction, or wave and particle, and makes an account of modern mathematics and science into something as eerie as a great ghost story" - New Statesman, Books of the Year

"A gripping meditation on knowledge and hubris... His prose is masterfully paced and vividly rendered in Adrian Nathan West's magnetic translation... With his slippery hybrid of fact and fiction, Labatut slyly applies the uncertainty principle to the human pursuit of knowledge itself" - New York Times

"It is a story about nature's fightback against human interference. In other words it is the story of the 21st century. In a literary industry obsessed with genres, it belongs to none" - New Statesman, Books of the Year

"Compelling, startling and utterly original. This book about physics is a work of art" - Christie Watson

"[A]n exquisitely written and continuously fascinating hybrid work of fiction and history" - Irish Times

"It may be possible to actually feel your brain getting bigger as you read" - Evening Standard

"Tantalising... This is a truly thrilling work of imagination and chutzpah" - Big Issue

"The new Bolaño" - Revistas Lecturas

"Labatut shakes his readers and gifts them thought-provoking images, planting in them the necessity to read everything he's written and everything he writes as quickly as possible" - La Tercera

"Labatut penetrates into the heart of a reality that only few have seen before him - and no one has yet described. A book of terrifying beauty" - Wolfram Eilenberger, author of Time of the Magicians

"Remarkable... melodiously poetic, but precise... Due to the increasing space that Labatut grants to fiction, he succeeds in giving an aesthetic answer to the question of the limits of knowledge: where there is uncertainty, literature grows a special power to enable experience. In this way, fiction can preserve the enlightenment of the blind" - Die Zeit

"He meticulously describes the moods and experiences of his historical protagonists. With this fictional approach, Labatut creates a bewitching closeness and immediacy. And at best a deeper, almost poetic understanding of what Schwarzschild's singularity or Heisenberg's uncertainty principle actually mean for our reality" - Deutschlandfunk Kultur

"The limits of human knowledge: this is the territory in which Labatut, with great vigour and extraordinary intellectual rigour, enters in this admirable book" - Expresso (Portugal)
