In quantum mechanics, this equation governs how the wavefunction ψ(x,t) changes — describing a particle not as a point, but as a spread of probabilities in space. A Gaussian wave packet starts localized. As time evolves, it naturally disperses — not due to noise or randomness, but as an exact consequence of quantum uncertainty encoded i
