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...

Katherine E. Macarthur

Harsha, if you reframe your question and make it more specific you might get a more helpful answer. Do you mean how do you get atomic ratios from EDX maps? Is it in TEM or SEM? What is the material?

Duc-The Ngo

It is just the basic calculation on EDX spectrum. EDS software helps you to do such a basic thing
