Kroese, Robert. Schrödinger's Gat. Seattle: CreateSpace, 2012. ISBN 978-1-4903-1821-9.
It was pure coincidence (or was it?) that caused me to pick up this book immediately after finishing Dean Radin's Real Magic (May 2018), but it is a perfect fictional companion to that work. Robert Kroese, whose Starship Grifters (February 2018) is the funniest science fiction novel I've read in the last several years, here delivers a tour de force grounded in quantum theory, multiple worlds, free will, the nature of consciousness, determinism versus uncertainty, the nature of genius, and the madness which can result from thinking too long and deeply about these enigmatic matters. This is a novel, not a work of philosophy or physics, and the story moves along smartly with interesting characters including a full-on villain and an off-stage…well, we're not really sure. In a postscript, the author explicitly lists the “cheats” he used to make the plot work but notes, “The remarkable thing about writing this book was how few liberties I actually had to take.”

The story is narrated by Paul Bayes (whose name should be a clue we're about to ponder what we can know in an uncertain world), who we meet as he is ready to take his life by jumping under a BART train at a Bay Area station. Paul considers himself a failure: failed crime writer, failed father whose wife divorced him and took the kids, and undistinguished high school English teacher with little hope of advancement. Perhaps contributing to his career problems, Paul is indecisive. Kill himself or just walk away—why not flip a coin? Paul's life is spared through the intervention of a mysterious woman who he impulsively follows on a madcap adventure which ends up averting a potential mass murder on San Francisco's Embarcadero. Only after, does he learn her name, Tali. She agrees to meet him for dinner the next day and explain everything.

Paul shows up at the restaurant, but Tali doesn't. Has he been stood up? He knows next to nothing about Tali—not even her last name, but after some time on the Internet following leads from their brief conversation the day before he discovers a curious book by a recently-retired Stanford physics professor titled Fate and Consciousness—hardly the topics you'd expect one with his background to expound upon. After reading some of the odd text, he decides to go to the source.

This launches Paul into an series of adventures which cause him to question the foundations of reality: to what extent do we really have free will, and how much is the mindless gears of determinism turning toward the inevitable? Why does the universe seem to “fight back” when we try to impose our will upon it? Is there a “force”, and can we detect disturbances in it and act upon them? (The technology described in the story is remarkably similar to the one to which I have contributed to developing and deploying off and on for the last twenty years.) If such a thing could be done, who might be willing to kill to obtain the power it would confer? Is the universe a passive player in the unfolding of the future, or an active and potentially ruthless agent?

All of these questions are explored in a compelling story with plenty of action as Paul grapples with the mysteries confronting him, incorporating prior discoveries into the emerging picture. This is an entertaining, rewarding, and thought-provoking read which, although entirely fiction, may not be any more weird than the universe we inhabit.
