## TL;DR

Quantum mechanics describes physical systems at atomic scales with quantization, wave functions, and uncertainty. This repair keeps foundational facts source-mapped.

## Core Explanation

The previous entry had weak coverage. The repaired version uses reference and Nobel sources for Planck, Schrodinger, and Heisenberg-era foundations.
