Experiment of the century

Joy Christian has proposed a macroscopic experiment to verify his theory in 2012 described in 'Macroscopic Observability of Spinorial Sign Changes under 2pi Rotations'. Now he and Richard Gill seems to have agreed on a bet to have this experiment performed in the presence of mutually trusted physicist. The stakes will be several thousand Euros. 

Joy's experiment is further described on his blog. It consists of balls that can be split in two identical halves. Each half contains a relatively heavy weight randomly attached to the hemisphere. The balls are given a random torsion, and, by heating them a bit, explode in the two hemispheres. The rotation of these halves will be registered by sensors. 

He has been trying to raise funds for this experiment since then. On Feb. the 22th Richard and Joy have settled the first terms for this experiment using the FQXI () forum here.
Andrei Khrennikov and Lucien Hardy, Hans De Raedt, Steve Weinstein (Perimeter), and Christopher Fuchs will be requested to be adjudicators for the experiment. We look forward to this happening!

New models by Richard Gill and Chantal Roth in 'R'

Richard Gill has presented some EPR simulations made in the computer language 'R'.

• Michel Fodje's simulation in Python (https://github.com/minkwe/epr-simple/) of the model from Joy Christian converted to R: http://rpubs.com/gill1109/13325
• Chantal's Java model (see link on the right side of this page) in R: http://rpubs.com/gill1109/13329
  and http://rpubs.com/chenopodium/epr2

The last two implementations give a nice overview of which CHSH can be obtained when allowing a part of the particle pairs not to be detected.

The simulation that implements Joy Christian's model is discussed at http://www.sciphysicsforums.com/spfbb1/viewtopic.php?f=6&t=11. In short this simulation also leaves out a part of the initial particle pairs, so some say it makes use of the detection loophole. Joy argues that in his model these particle states do not exist, so should not be counted anyway.
