A first-principles approach to physics based on locality and operationalism

Understand

Starting from the guiding principles of spacetime locality and operationalism, a general framework for a probabilistic description of nature is proposed.

• Crucially, no notion of time or metric is assumed, neither any specific physical model.
• Remarkably, the emerging framework converges with a recently proposed formulation of quantum theory, obtained constructively from known quantum physics.
• At the same time the framework also admits statistical theories of classical physics.
