German theoretical physicist and author of Lost in Math who argues that modern theoretical physics has gone astray by valuing mathematical beauty over empirical testability — becoming the most prominent scientific critic of string theory and supersymmetry.

Made the systematic case that particle physics and quantum gravity have spent decades pursuing mathematically elegant theories (string theory, supersymmetry) that make no testable predictions — identifying beauty bias as the primary pathology of modern theoretical physics.
