This magnificent and timely series of ontology essays (what's real and what isn't, in a nutshell) brings us up to date on both physics and philosophical thinking about quantum waves, states and phases. Superposition (essentialy solutions that are linear in the sense that, when added, are still solutions), wave collapse, and quantum waveforms (probabilities equalling 1 because there is a 100% chance the particle is there in that probability wave/cloud "somewhere") have long been debated as either in the observer's mind, or "real" in the tiny, chilly subatomic quantum universe(s).
That little (s), was added because, yes, topics like Everett (the many worlds interpretation) are covered along with other more "populist" observer ideas, but not in the usual "wow" mess of speculative, inexact pop ramblings-- the authors and contributors strike a wonderful balance between the math, physics and philosophy, without either degenerating into pseudo-spiritual "this is like Buddhism" or the equally painful semantic parsing of terms so prevalent in philosophy.
The book is mind bending, and even though decidedly realist and relatively dry, doesn't trash talk or remove the mystery. There is an unusual humility, and even though many of the earlier debates have been clarified with new research, they certainly haven't been solved. Although the arguments are at a very sophisticated level, some of the contributors do break the dryness with "quantum humor" like the mysterious power of the observer changing reality by just "looking" -- albeit looking with high energy xray eyes!
The book, even though it doesn't pretend to solve the issues it debates and raises, covers enough pro con to give the reader's brain a great workout, updating the classical arguments with both new data and new arguments. After all, the greatest minds in physics couldn't agree on whether, essentially, all quantum reality is human-projected, a Platonic ideal form we're groping at like the blind folks and the elephant, or a completely ideal sim we just use to understand the ineffable. There are still mathematical constructs that defy discounting, and truly seem to be "there" in the sense of the "matrix" -- running beneath reality regardless of or despite our "discovery" vs. "creation" of their graphs, waveforms and formulas.
The "with it" trend in materialistic science today is to try to ascribe "mini Darwinism" at the molecular level, and soon, the quantum level. The alternative is the amazing teleology of human thought wave-sims (a whole new take on plasticity), which can happen without even firing off that neuron spike. Tse's fascinating new book looks at this in detail: The Neural Basis of Free Will: Criterial Causation. The contributors here, though sympathetic to realist-reduction, are also open to far beyond probable aspects of "reality." As such, most of the articles focus on the details of individual quantum quandaries more than global metaphysical issues.
It is interesting that the publisher allows a LOT of "inside" argument-- complex to the point of being for physicists/ between physicists rather than "popular science." I'm hoping this courage won't lessen the appeal of this volume for those of us willing to spend the extra work to get it. IOW, I hope the authors are rewarded for not dumbing down or trivializing the controversies to sell more copies. To be cruelly honest, in a Christian culture, many debates like this either turn off the reader by acting like people of faith are idiots, or pandering to them by creating mysteries where there aren't any, or where we don't have a clue why we don't get it. There are plenty mysteries covered here, but the authors and contributors, in general, are professional and sympathetic to multiple viewpoints. I mean, in quantum, if being a "realist" can include every possibility happening in some universe-- wow, you've got to be at least a LITTLE out of the box, even if you're a determined, skeptical, "show me" Iowan!!! Highly recommended, but not a page turner or populist exploration.
EMAIL QUESTION: "Is there a lot of math in this book?" Actually, no, not as formulas, Hermitian operators in Hilbert Space, derivations of the gravitational constant, etc. But there are some excellent "verbal" discussions of some of the problems behind the math. For example, rather than give details of the wave function, the articles explore questions of whether the wave function "operates" as some law of motion (or as a "physical" wave) in some dimension, or is just a mental/mathematical tool (or, I'd add: both?). There is some math explaining N-dimensional space to ask, again for example, where the function would "operate" -- but nothing very complex or detailed. So... don't worry! The authors also go over a LOT of basics to prepare you if you're not up on the latest questions, so the book really is accessible to the general math-shy reader.
