Lost in Math? A review of 'Lost in Math: How Beauty Leads Physics Astray', by Sabine Hossenfelder

This is a review of Hossenfelder's book, 'Lost in Math: How Beauty Leads Physics Astray'. The book gives a breezy exposition of the present situation in fundamental physics, and raises important questions: both about the content of the physics, and the way physics research is organized. I first state my main disagreements. Then, I mostly praise the book: I concentrate on Hossenfelder's discussion of supersymmetry, naturalness and the multiverse.
