Does probability become fuzzy in small regions of spacetime?

Thermodynamics on Fuzzy Spacetime

We investigate the thermodynamics of non-relativistic and relativistic ideal gases on the spacetime with noncommutative fuzzy geometry. We first find that the heat capacities of the non-relativistic ideal boson and fermion on the fuzzy two-sphere have different values, contrast to that on the commutative geometry. We calculate the “statistical interparticle potential” therein and interprete thi...

Modal Logics of Regions and Minkowski Spacetime

The paper studies modal logics of Kripke frames, in which possible worlds are regions in space with natural accessibility relations. These logics are also interpreted as relativistic temporal logics. Together with an overview, we prove some new results on completeness, decidability, complexity, and finite axiomatizability.

Fuzzy Gravitons From Uncertain Spacetime

The recently proposed remarkable mechanism explaining “stringy exclusion principle” on an Anti de Sitter space is shown to be another beautiful manifestation of spacetime uncertainty principle in string theory as well as in M theory. Put in another way, once it is realized that the graviton of a given angular momentum is represented by a spherical brane, we deduce the maximal angular momentum d...

When does conscientiousness become perfectionism ?

Gordon L. Flett, PhD Canada Research Chair in Personality and Health York University Toronto Mr. C is a 50-year-old professional writer who recently made a serious suicide attempt. At his initial session, Mr. C was hesitant to discuss his situation and reason for attending. He did, however, bring a copy of his résumé so the therapist could “get to know him quickly.” He said he had been depresse...
