1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Natalia Kasian Brownian motion will mean that the particles will be moving violently in the liquid. However, in a nematic LC, they could be more constrained to a plane, helping imaging, but I have no idea. Also, these sizes are close to the resolution of SEM. I’d look to freeze-fracture or, better still, cryoEM for morphological studies of your system.
