pilot wave

French physicist Louis de Broglie (1892-1987) hoped that quantum mechanics could be brought within the same frame as classical physics via pilot wave theory, which envisioned “concrete particles, always with definite locations, that are guided through space by real pilot waves.” Apparently not. But a series of bouncing-droplet findings since 2015 has crushed this dream. The results indicate that Couder’s most striking demonstration of quantum-like phenomena, back in 2006 — “the experiment that got me hooked on this problem,” the fluid dynamicist Paul Milewski said — was in error. Repeat runs of the experiment, called the “double-slit experiment,” have contradicted Couder’s initial results and revealed the double-slit experiment to be the breaking point of both the bouncing-droplet analogy and de Read More ›
