  We discuss the time development of Gaussian wave packet solutions of the
quantum bouncer' (a quantum mechanical particle subject to a uniform downward
force, above an impermeable flat surface). We focus on the evaluation and
visualization of the expectation values and uncertainties of position and
momentum variables during a single quasi-classical period as well as during the
long term collapsed phase and several revivals. This approach complements
existing analytic and numerical analyses of this system, as well as being
useful for comparison with similar results for the harmonic oscillator and
infinite well cases.
