Existential Physics is an introduction and exploration of some of the most profound questions that physics has attempted to answer, and a discussion of whether these explanations are plausible or even count as physics. It is undeniable that modern physics has become extremely weird, with attempts to explain things like quantum physics, general relativity and the standard model of particle physics leading to even weirder hypotheses. They settled on reading Hossenfelder’s Existential Physics as their next book, and since they didn’t have a physicist in the group, Mark asked if I was interested in joining them? I was, because the book club sounded fun, and I’m also Twitter friends with Sabine and was quite confident that the book would be an interesting read! So in discussing the book, I can not only talk about my reactions as a physicist, but also the reactions of colleagues in theater, linguistics, software and information systems. My friend Mark at my university that I’ve known since I became a professor some 15 years ago has been running a book club with colleagues from a number of departments. I read this book recently due to somewhat curious circumstances.
