2.2 The Nature of Physics

summary
Fixed Physical Interactionsdrop-down

  • Given the context and the initial conditions, the outcome (in classical physics) is inevitable.
  • For example, gravity is always an inverse-square law, with no deviations.
  • In the quantum case, the individual outcomes are random, but the statistics, when many events are considered, are highly predictable.
  • Intentions or choice is not a factor in either the classical or quantum case.


The Logic of Physicsdrop-down

  • Physical laws determine evolution of a physical system in a purposeless and inevitable way.
  • Dynamical laws determine later states from earlier states, when the context and initial boundary conditions are known.
  • The outcomes are testable and repeatable.
