Abstract

We propose a third physical logics. The first was classical (C) logics with commutative distributive AND and OR. The second is commutative quantum (CQ) logics, with commutative nondistributive AND and OR. The third logics, Q, has noncommutative nondistributive AND and OR; Q⊃CQ⊃C. Q predicates are the rays in a Grassmann double algebra of extensors, where CQ predicates are the subspaces of a Hubert space. The AND and OR of Q are projectively represented by Grassmann's progressive and regressive products. Q supports a quantum set theory appropriate to quantum topology. Here Q is applied to a toy theory of the topology of time. It preserves translational invariance and replaces singular delta-function propagators by finite Gaussians.
