Schroedinger's Equation at 100: The Wave Picture That Helped and Possibly Hurt

Caslav Brukner · 2026

Schroedinger's equation gave early quantum theory a visual language that looked like physics again: a wave evolving by a linear differential equation. This essay argues that the same success also seed…
