Quantum mechanics is seen as challenging the idea that science provides objective descriptions of reality outside of our minds. The “measurement problem” seems to suggest that the act of observation creates the outcome that is observed. But physicist Antony Valentini argues that this picture rests on an enormous blunder by Erwin Schrödinger. After Louis de Broglie predicted the wave-like trajectories of particles, Schrödinger found the equation describing this. But whereas de Broglie envisaged particles riding on waves, Schrödinger kept the waves and threw away the particles. That single decision birthed the measurement problem—and it was completely unnecessary. Resurrect de Broglie’s original particle-based theory, Valentini argues, and we can dispel quantum mystery.
