Two weeks ago I heard a very interesting EconTalk podcast[1] by Sabine Hossenfelder on Physics, Reality, and Lost in Math. Hossenfelder herself is a theoretical physicist, and researches quantum gravity. And a Research Fellow at the Frankfurt Institute for Advanced Studies. She has a refreshing tone and frankness, and I appreciated learning about her work. Quoting the podcast's abstract: "Hossenfelder argues that the latest theories in physics have failed to find empirical confirmation. Particles that were predicted to be discovered by the mathematics have failed to show up. Whether or not there is a multiverse has no observable consequences. Hossenfelder argues that physicists have become overly enamored with the elegance and aesthetics of their theories and that using beauty to evaluate a model is unscientific. The conversation includes a discussion of similar challenges in economics."
