Quantum Mechanics. The Theoretical Minimum -

The Schrödinger Equation governs how things change. It’s deterministic, predictable—until you touch it. I closed my eyes, letting the "unitary evolution" of the room carry me. I didn't fight the shifts. I didn't try to "measure" my position. I became a wave, spreading out across the lab, the hallway, and the parking lot outside.

The notebook was bound in cheap leather, the kind that smelled like old library basements. On the cover, Art had scrawled four words in permanent marker: THE THEORETICAL MINIMUM . Quantum mechanics. The theoretical minimum

This request appears to be inspired by the book Quantum Mechanics: The Theoretical Minimum by Leonard Susskind and Art Friedman. The Schrödinger Equation governs how things change
