Nonlocality, Bell’s Ansatz, and probability

Probability and Nonlocality in Many Minds Interpretations of Quantum Mechanics

We argue that a certain type of many minds (and many worlds) interpretations of quantum mechanics due to Lockwood (and Deutsch) do not provide a coherent interpretation of the quantum mechanical probabilistic algorithm. By contrast, in Albert and Loewer’s version of the many minds interpretation there is a coherent interpretation of the quantum mechanical probabilities. We consider Albert and L...

Nonlocality without nonlocality∗

Bell’s theorem is purported to demonstrate the impossibility of a nonlocal “hidden variable” theory underpinning quantum mechanics. It relies on the well-known assumption of ‘locality’, and also on a little-examined assumption called ‘statistical independence’ (SI). Violations of this assumption have variously been thought to suggest “backward causation”, a “conspiracy” on the part of nature, o...

Bells, Motels and Permutation Groups

This article is about the mathematics of ringing the changes. We describe the mathematics which arises from a real-world activity, that of ringing the changes on bells. We present Rankin’s solution of one of the famous old problems in the subject.

Groups and Bells

We describe the mathematics which arises from a real-world activity, that of ringing the changes on bells. We present Rankin's solution of one of the famous old problems in the subject, and some open questions.
