This applet illustrates the fundamental building blocks of one-dimensional quantum mechanics, the energy eigenfunctions  ψ_n(x) and energy eigenvalues E_n.  The user enters the expansion coefficients into a table and the simulation uses the superposition principle to construct and display a time-dependent wave function using either infinite square well (ISW) or simple harmonic oscillator (SHO) eigenfunctions.
