# Physics with exotic probability theory

Probability theory can be modified in essentially one way while
maintaining consistency with the basic Bayesian framework. This
modification results in copies of probability theory for real,
complex or quaternion probabilities. These copies, in turn, allow
one to derive quantum theory while restoring standard probability
theory in the classical limit. These exotic theories are quite
substantially simpler than quantum mechanics both conceptually and
mathematically. I'll explain how this comes about, discuss Field
theory results by Srinivasan and attempt to formulate questions
which go beyond basic quantum theory where new insights are
needed. Some of this material is available as hep-th/0110253.
