The famous theorem of Cobham says that, for multiplicatively independent integers k and l, any subset of N, which is both kand l-recognizable, is recognizable. Many of its proofs are based on so called Hansel’s lemma stating that such a kand l-recognizable set is syndetic. We consider these proofs and point out that some of them are inadequate.

I describe the metaphoric process and its spatiotemporal aspects, and argue that, in order to explain its dynamics, a framework based on processes with variable ...

The measurement conundrum seems to have plagued quantum mechanics for so long that impressions of an inconsistency amongst its axioms have spawned. A demonstration that such purported inconsistency is fictitious may then be in order and is presented here. An exclusion principle of sorts emerges, stating that quantum mechanics cannot be simultaneously linear and introspective (self-observing).
