today Alain Connes (with co-author Matilde Marcolli) posted http://arxiv.org/abs/hep-th/0411114 Physics to Number Theory via Non-Commutative Geometry, Part II Part I got a big play on SPR, we should know something about this. Maybe only a little. But something. Part One of "Physics to Number Theory" was http://arxiv.org/math.NT/0404128 I cant do more than flag these two papers. If this thread goes anywhere it will have to be by other people having comments to make about non-commutative geometry applied to physics.
