The physics

Put a quantum particle in a parabolic well, a mass on an ideal spring, and it can only have certain energies.

They form an evenly spaced ladder, E = (n + ½)ħω. Werner Heisenberg found it in 1925 with his new matrix mechanics, and Schrödinger found it again from his wave equation a year later.

Each rung in the art is the probability density |ψₙ|² for n = 0 to 5, a Hermite polynomial times a Gaussian, drawn on its own energy level inside the parabola. Level n has n zeros where the particle is never found.

The lowest rung is not at zero. Confining the particle forces some momentum on it, by the uncertainty principle, so even the ground state keeps ½ħω.

Never quite still.

\[\psi_n(\xi) = \frac{1}{\sqrt{2^nn!\sqrt\pi}}\,H_n(\xi)\,e^{-\xi^2/2},\quad \xi = x\sqrt{m\omega/\hbar}\]
