Erwin Schrödinger

July 2026

Who he was

Erwin Schrödinger (1887–1961) was an Austrian physicist. His 1926 wave equation for quantum mechanics — describing how a quantum system’s wavefunction evolves over time — remains one of the central equations of physics, and earned him a share of the 1933 Nobel Prize in Physics with Paul Dirac.

What he’s known for on this site

The Schrödinger equation is what produces the exact hydrogen-atom orbital shapes shown in Hydrogen Orbital Probability Density — one of the few problems in quantum mechanics solvable exactly in closed form. The symbol he introduced for the wavefunction, $\psi$, is documented in the Symbols & Units catalog.

Catalog status: Proven Systems

The Schrödinger equation and hydrogen’s exact orbital solutions are core, extensively confirmed quantum mechanics, verified by spectroscopy for a full century.

Where this touches PBT

PBT doesn’t currently offer its own derivation of hydrogen’s orbital shapes — this is standard quantum mechanics, used on this site exactly as mainstream physics defines it, with no PBT-specific claim attached.
