The virtual orchestra of quantum mechanics

Buy me a coffee and support the channel: https://ko-fi.com/jkzero In this journey towards Heisenberg's matrix formulation of quantum mechanics, here I present the idea of "virtual oscillators" that were hiding in Ladenburg quantum interpretation of dispersion. How Kramers extended Landebunrg's results, and set one of the basic components of Heisenberg's matrix mechanics.
