Last year, Matt Strassler explained that particles are really a kind of wave (21 September 2024, p 32). Now, Celso Villas-Boas says that no, they are really just particles after all(3 May, p 8). Arguments are traditionally settled with a duel. Electron guns at 20 paces? Or a more modern cage fight, with the mesh replaced by diffraction slits? Or perhaps a surfing competition?
