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...

Thanks a lot Prof. Martin.

Hello

If you are looking for a physical model which describes the thermal conductivity of your material (sapphire) you should inspect the conventional one for lattice conductivity. This is the Debye-Callaway model. There are lots of informationa bout that

https://books.google.es/books?id=DPlqgGwTkcoC&pg=PA43&lpg=PA43&dq=callaway+thermal+conductivity&source=bl&ots=sUgGFJgxvs&sig=SiFU3P0N5zq8INSTxUqPzJai-Gk&hl=es&sa=X&ved=0ahUKEwiwy-2FuKvVAhXKDxoKHWh1C3cQ6AEIdzAJ#v=onepage&q=callaway%20thermal%20conductivity&f=false

Good luck, ask me for more info if you need it.

Thanks a lot Prof. Oscar. Sure, I will have a look at this book.
