A Common-Sense Look at Wave–Particle Duality

This paper argues that a core quantum “mystery” may come from one basic misread: we treated different results under different test conditions as proof that a particle is wave and particle at the same time. From that single leap, many controversial ideas—like strong versions of superposition and “the observer creates reality”—became popular, and this paper proposes a simpler alternative: the behavior changes because the setup changes, not because nature is logically contradictory.
