I love watching those vibrating plate / sand demonstrations (but they sound aweful haha).
From a physics point of view the sand is attracted to the nodes of the solution to the wave equation with the boundaries of the plate and driven by the frequency of vibration. If you study physics in a formal context, a huge portion of all problems you will solve simply reduce to solving the wave equation (or closely related equations) with certain boundary conditions... ranging from electron orbitals to properties of crystalline solids to planetary orbits. It's no wonder they appear very primal and fundamental.

Thats an interesting way of thinking about reality 
I wouldn't say its very "scientific" but it has some truth. Scientifically any open space, wire, crystal lattice, any system capable of vibration, that is above absolute zero temperature, is vibrating semi randomly with noise. For example, the old idea of putting your ear up to a seashell and hearing the ocean is listening to the noise excitations of that resonant space. The reason such well defined patterns emerge on those plates is because they are being driven with a very specific frequency. If they were driven by noise like many natural systems in equilibrium the patterns would appear more random. If you wanted to increase the level of abstraction of your idea you would have to invent a medium (say, aether) that is vibrating and also invent what it is that is vibrating and find a correlation between those abstractions and a measurable physical system. This is a very challenging idea to follow through methodically.. I believe a lot of very intelligent people have tried unsuccessfully. When physics reaches that level of abstraction I wonder if it is really worth pursuing.

those are some very interesting perspectives and explanations ouro, thanks for sharing
i like the "wave function" idea..it clicks..
i agree that physics will soon become very abstract, and the classical ideas will break down. quantum physics is the doorway
