This paper examines why quantum mechanics appears strange when viewed from a classical perspective. It argues that the perceived “weirdness” arises from an incomplete understanding of the transition between the quantum and classical regimes. By identifying a coherence-limited boundary defined by entropy flow, the paper clarifies why quantum systems behave reversibly and why classical behavior emerges only when this boundary is crossed. The result is a simple physical bridge that resolves many of the puzzles usually attributed to interpretation.
