Mad-Dog Everettianism: Quantum Mechanics at Its Most Minimal

Understand

To the best of our current understanding, quantum mechanics is part of the most fundamental picture of the universe.

• It is natural to ask how pure and minimal this fundamental quantum description can be.
• The simplest quantum ontology is that of the Everett or Many-Worlds interpretation, based on a vector in Hilbert space and a Hamiltonian.
• Typically one also relies on some classical structure, such as space and local configuration variables within it, which then gets promoted to an algebra of preferred observables.
