Introduction to the Industrial Internet,David Mermin proposed a gedanken experiment leading to a simple version of Bell’s Theorem. His argument is recalled and developed here. Its assumptions — that a source state exists, that a detector reading depends only on the source state and the detector setting, and that detector settings and source states vary independently — are noted.

CSR, Sustainability, Ethics & GovernanceJarrett claims to have shown that a logical equivalence holds between the condition he calls “locality” and the relativistic ban on superluminal signalling. This is misleading in an important respect: the speed of the signalling plays no essential role in the proof. Given this, an argument against the validity of the proof is easily constructed.

On a Theory of the Collapse of the Wave Function,The quantum-mechanical measurement problem is reviewed, and a recent attempt (due to Ghirardi, Rimini, and Weber) to solve that problem by means of a theory of the collapse of the wave function is described. The theory is applied to the case of a Stern-Gerlach type spin-measurement, and is shown to run into some interesting difficulties there.
