"This is a delightful account of one of the deepest and most fascinating explorations going on today at the frontier of our knowledge." —Carlo Rovelli, bestselling author of The Order of Time and Seven Brief Lessons on Physics

A revelatory exploration of how a "theory of everything" depends upon our understanding of the human mind

The whole goal of physics is to explain what we observe. For centuries, physicists believed that observations yielded faithful representations of what is out there. But when they began to study the subatomic realm, they found that observation often interferes with what is being observed—that the act of seeing changes what we see. The same is true of cosmology: our view of the universe is inevitably distorted by observation bias. And so whether they're studying subatomic particles or galaxies, physicists must first explain consciousness—and for that they must turn to neuroscientists and philosophers of mind.
Neuroscientists have painstakingly built up an understanding of the structure of the brain. Could this help physicists understand the levels of self-organization they observe in other systems? These same physicists, meanwhile, are trying to explain how particles organize themselves into the objects around us. Could their discoveries help explain how neurons produce our conscious experience?
Exploring these questions and more, George Musser tackles the extraordinary interconnections between quantum mechanics, cosmology, human consciousness, and artificial intelligence. Combining vivid descriptions with portraits of scientists working on the cutting edge, Putting Ourselves Back in the Equation shows how theories of everything depend on theories of mind—and how they might be one and the same.

      Starred review from September 11, 2023
      “Explaining our inner experience might require new physics,” according to this electrifying report. Science writer Musser (Spooky Action at a Distance) surveys how physicists, who since René Descartes have largely studied matter as distinct from the mind, are now attempting to explain the vagaries of subjective experience and consciousness. Quantum theory, he notes, has forced physicists to consider the human mind because the presence of “sentient observers” affects the location of quantum particles, which remain in an indefinite state “not sitting anywhere in particular” until observed. Musser explores the fascinating ways in which scientists are studying the physics of the mind, including theoretical quantum “meta-experiments” that consider situations in which “observers observe other observers.” Other researchers are building artificial neural networks (digital “webs of basic computing units”) to better understand how neurons, which function as biological computing units, contribute to cognitive function and consciousness. Musser has a talent for distilling complex science into accessible language, as when he explains that Italian physicist Carlo Rovelli’s theories about gravity imply that “things have no properties in isolation but acquire them only at their point of contact with other things,” raising provocative questions about the nature of objective reality. Lucid and endlessly intriguing, this will expand readers’ minds.
