SUPPLEMENT / TWO-MODE SKETCH
Two prescribed modes.
Move the phase. Change the mix. Watch two simple modes form one surface. This is an illustrative mathematical model you can explore in your browser.

SURFACE RMS / MODEL UNITS
Root mean square height across the sampled grid.
ψ(x,y,t) = sin(1.6x − t) + a · cos(1.8y + 0.7t + φ)The surface is the sum of two prescribed modes. It illustrates superposition; it is not a simulation of an atom or evidence for an extra physical dimension.
