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...

Eugene F Kislyakov

Nonlinearity.

L. Herojit Singh

Dear Eugene, can you please give me some reference. I will be very happy for it.

I only have Russian books. Any book on molecular spectroscopy may be usefull as a source of references.

Regards,

Eugene.

The most short and clear explanation is in "Mechanics" after Landau and Lifshiz (the first volume of their famous series).

thank you very much

Ke Lin

I think the fundamental modes are more important.
