A Comparison of Two Presentations of Quantum Mechanics - Everett's Relative-State and Rovelli's Relational Quantum Mechanics

Everett’s Relative State Formulation of Quantum Mechanics and Rovelli’s Relational Quantum Mechanics are two eminently interesting and impactful presentations of what the world of quantum mechanics is like. Beginning with a depiction of the theories and their physical implications I conclude with a comparison of their respective picture of reality. I propose here that by letting philosophical deliberations be guided by the very statements from within the theories, one arrives at a structural realist picture of what our world is like.
