• Abstract: We demonstrate the existence of a complex Hilbert Space with Hermitian operators for calculations in classical electromagnetism. This approach lets us derive a variety of fundamental expressions for electromagnetism using minimal mathematics and a calculation sequence well-known for traditional quantum mechanics. The purpose of this Hilbert Space is not to calculate the expectation values of known observables, however, like in Koopman-von Neumann-Sudarshan (KvNS) mechanics (for classical point particles) and quantum mechanics (quantum waves or fields). We also demonstrate the existence of the wave commutation relationship $[\hat{x},\hat{k}]=i$, which is the never seen before classical analogue to the canonical commutator $[\hat{x},\hat{p}]=i\hbar$. The difference between classical and quantum mechanics lies in the presence of $\hbar$. This is the first report of noncommutativity of observables for a classical theory. Further comparisons between electromagnetism, KvNS classical mechanics, and quantum mechanics are made. Finally, supplementing the analysis presented, we additionally demonstrate for the first time a completely relativistic version of Feynman's proof of Maxwell's equations \citep{Dyson}. Unlike what \citet{Dyson} indicated, there is no need for Galilean relativity for the proof to work. This fits parsimoniously with our usage of classical commutators for electromagnetism.

  A classical state-preparation device cannot generate superpositions and hence its emitted states must commute. We show that no such simulation exists, thereby certifying quantum coherence. Our approach is a possible avenue to understand how and to what extent quantum states defy generic models based on classical devices.

• Non-Heisenbergian quantum mechanics [0.0]
  Relaxing the postulates of an axiomatic theory is a natural way to find more general theories. Here, we use this way to extend quantum mechanics by ignoring the heart of Heisenberg's quantum mechanics. Perhaps surprisingly, this non-Heisenberg quantum theory, without a priori assumption of the non-commutation relation, leads to a modified Heisenberg uncertainty relation.

We will show that finitely exchangeable probabilities for a classical dice are as weird as QT.
