This model simulates a particle confined to a rigid, zero-potential well. It introduces the concept of boundary conditions and shows why energy levels become quantized (
: When a PDF note shows a derivation, grab a piece of paper and write it out line-by-line. Make sure you understand the calculus or linear algebra step between each line.

This model confines a particle to a one-dimensional region of zero potential energy surrounded by infinite potential walls.
Detailed descriptions of operators for energy, momentum, and angular momentum. Conclusion
Physically accurate but computationally difficult to calculate.
: You systematically vary parameters in a trial wavefunction to minimize the calculated energy, getting as close to the true answer as possible. Perturbation Theory
Currently the most popular method in chemistry and materials science. It models the system based on electron density rather than the wave function.
