Adam Becker: What is Real? The Unfinished Quest for the Meaning of Quantum Physics. (2018)
Tue, May 13, 2025./noise/books | LinkKindle. A pointer from Jennifer Szalai's review of Becker's More Everything Forever (2025) which I won't be reading now.
Notionally Becker aims to dispel any lingering belief that the Copenhagen interpretation is a viable account of how quantum mechanics relates to reality. The key difficulty, as Becker admits semi-regularly, is that this interpretation is too ill-defined to wrestle with. That Becker proceeds to do a poor job with the wrestling does not help us understand why so many big-brained physicists let it ride. (Sure, this is a matter for philosophy, not physics, but even so.) Alloyed with too much assertion and insufficient argumentation, the bulk of the text is an attack on strawmen and a championing of the multiverse and pilot waves. The prose often gets bogged in short-order repetition; a hefty edit was in order. I mostly didn't feel like I was thinking. It's never made clear what might count as real. The major historical figures were drawn more incisively by Labatut (2021).
I wasn't impressed with his take on the philosophy of science, especially his sinking the boot into the Vienna Circle; this is particularly tiresome when fecund philosophers like Rudolf Carnap are name-dropped without any discussion of their contributions. Yes, verificationism, logical positivism, whatever are long bankrupt but it's not so easy to dispense with conceptual analysis and Popperian falsification (to me a necessary but not sufficient quality of a scientific theory), especially on the basis that we can never figure out the specific parts of a theory that deserve revision; Ehud Shapiro showed how to operationalise falsificationalism back in the 1980s (see MIS) and of course this problem is most of what training an AI has always been about. Perhaps Becker needed to peruse Chalmers's classic.
Broadly reviewed. James Gleick for the New York Times. Goodreads. Yes, the appendix is the best part of the book. If I'd read Peter Woit's take ahead of time I would've read something else, or maybe put my big-boy pants on and dug into the SEP articles.
