On: The unreasonable effectiveness of mathematics

[amelius]

It is probably not even possible to model how a drop hits the water with only a 2D cross-section. You probably need three dimensions to model it correctly.

In its present form, it is more like modeling how an infinitely long cylinder is hitting the surface of the water.

[thanatosmin → amelius]

Everything is radially symmetric, so a 2D polar coordinate system should be accurate.

[taejo → thanatosmin]

True, but note that if you do an actually simulation, waves act fundamentally differently in spaces of odd and even dimension.
