Cosmological Koans: A Journey to the Heart of Physical Reality

by Anthony Aguirre

Overview

“Playful and enchanting.” —Priyamvada Natarajan, Wall Street Journal

Could there be a civilization on a mote of dust? How much of your fate have you made? Using pleasingly paradoxical vignettes, known as Koans, that follow the ancient Zen tradition and have a flair for explaining complex science, physicist Anthony Aguirre tackles cosmic questions from the meaning of quantum theory and the nature of time to the origin of multiple universes.

Editorial Reviews

"[A] gem of a book."

Carlo Rovelli

02/25/2019

Everything from Newton’s laws to the Big Bang are probed in this hit-and-miss pop-physics primer. Aguirre, a physics professor and founder of the Foundational Questions Institute, prefaces bite-sized science lessons with paradoxical Zen koans—“the gateless gate lies open”—and episodes from a fictional picaresque about a 17th-century seeker who travels from Galileo’s Italy to China, with stops in a Buddhist temple and the cave of a djinn who subjects him to teleportation experiments and lectures on free will. The science explanations that flow from this lively framing device are uneven. Aguirre presents lucid, thought-provoking discussions of physicists’ evolving conceptions of space, time, motion, and forces, up through Einstein’s general theory of relativity, and his explorations of cosmic origins and the possibility of this universe being one among many are grandly engaging. But his complicated, murky exposition of quantum physics is not helped by Zen-like flourishes (“If you follow all paths equally, you end up just following a single path. The one true path”). Further disquisitions on mind and ontology—“what does it mean... to be something rather than, say, something else?”—are provocative but inconclusive. Readers will veer between “Whoa!” and “What?” on this sometimes stimulating, sometimes baffling tour of the cosmos. (May)

Publishers Weekly

"Playful and enchanting."

Wall Street Journal - Priyamvada Natarajan

"The universe is apparently paradoxical, but ultimately sensible. How better to illuminate that dichotomy than through Zen koans? This book is calisthenics for the mind—it will stretch your imagination almost to the breaking point, and your understanding of reality will come away more healthy and flexible than before."

Sean Carroll

"This unique and beautifully written masterpiece by a leading cosmologist transforms the deepest mysteries of our Universe into a captivating and accessible quest for personal enlightenment."

Max Tegmark

"Written by one of the most important cosmologists of his generation, Cosmological Koans draws the reader into the deeply philosophical quest implicit in modern cosmology: the quest to understand who and what we are. I can think of no other book that so effectively elicits a sense of wonder."

Jenann T. Ismael

"Physicists have pieced together dazzling theories of the universe and our place within it; yet deep questions remain. Cosmologist Anthony Aguirre rewards curious readers with a tour of some of the thorniest open questions. Beautifully written and thoroughly engaging—I couldn’t put it down!"

David Kaiser

"A truly creative exploration of physics and its profound insights into the Universe. A masterful writer, Anthony Aguirre has composed an accessible and entertaining exploration of the Cosmos and our place in it. This book is a delightful addition to popular accounts of both the foundations and frontiers of physics."

Adam Frank

"Readers may experience epiphanies clarifying scientific theories of the cosmically large and the subatomically small…Science and mysticism meld in this physics rendered as fully human life."

Booklist (starred review)

2019-03-17
A physicist and philosopher delivers a provocative set of meditations on the nature of life, the universe, and everything.

If you think hard enough about the unlikeliness that you are you—to say nothing of the fact that the universe is not only infinite, but also expanding—your head is likely to hurt. All the more so when Aguirre (Physics/Univ. of California-Santa Cruz; co-editor: What Is Fundamental?, 2019, etc.) throws in a monkey wrench on the latter point: "It's got just one glaring flaw: the actual universe that astronomers observe is not like this." Throw in other imponderables worth pondering, as the author does—e.g., "if the electric repulsion between protons in the nuclei of atoms were just a bit stronger, then those atoms, and hence chemistry, and hence life itself, could not apparently exist"—and the throbbing temple threatens to explode. Some of Aguirre's forays into cosmological questions can be as squishy as any New Age guru's, as when he asks us to consider ourselves not just part of the universe, but central to it, but he tempers the fuzziness with some truly engaging questions (and questions, he hints, are vastly more interesting than answers when it comes to matters of the universe). Of what, for instance, are atoms made? The textbook answer is quarks and mesons and electrons and such, but also, Aguirre writes, information. And not just any old information, but information that projects dimensionally, proving Zeno's paradox and Galileo's notion that "there is nothing particularly natural or easy or special about being at rest." Though written with the generalist in mind, Aguirre's arguments can be a little difficult to grok sometimes, which is probably the point: It stands to reason that "quantum reality is somewhat ambiguous," but it gets a little shaky when we ask, since everything is quantum mechanical, why do we die?

A delight for readers raised on books like Gödel, Escher, and Bach and The Dancing Wu Li Masters.
