Sternberg transitions into quantum mechanics by examining the hydrogen atom and the harmonic oscillator. He demonstrates how spherical harmonics emerge naturally as representations of the rotation group Part 3: Atomic Spectra and Selection Rules
The mathematical bedrock used to classify elementary particles. group theory and physics sternberg pdf
The book opens with discrete mathematics, analyzing point groups and space groups. This section explains how the macro-structural properties of crystals and solids are restricted by geometric symmetry. Part 2: Quantum Mechanics and the Rotation Group group theory and physics sternberg pdf
