A critical review of randomness criteria shows that nogo theorems severely restrict the validity of actual "proofs" of undecidability. It is suggested to test microphysical undecidability by physical processes with low extrinsic complexity, such as polarized laser light. The publication and distribution of a sequence of pointer readings generated by such methods is proposed. Unlike any pseudorandom sequence generated by finite deterministic automata, the postulate of microscopic randomness implies that this sequence can be safely applied for all purposes requireing stochasticity and high complexity.

Inasmuch as physical theories are formalizable, set theory provides a framework for theoretical physics. Four speculations about the relevance of set theoretical modeling for physics are presented: the role of transcendental set theory (i) hr chaos theory, (ii) for paradoxical decompositions of solid threedimensional objects, (iii) in the theory of effective computability (ChurchTurhrg thesis) related to the possible "solution of supertasks," and (iv) for weak solutions. Several approaches to set theory and their advantages and disadvatages for" physical applications are discussed: Cantorian "naive" (i.e., nonaxiomatic) set theory, contructivism, and operationalism, hr the arrthor's ophrion, an attitude of "suspended attention" (a term borrowed from psychoanalysis) seems most promising for progress. Physical and set theoretical entities must be operationalized wherever possible. At the same thne, physicists shouM be open to "bizarre" or "mindboggling" new formalisms, which treed not be operationalizable or testable at the thne of their " creation, but which may successfully lead to novel fields of phenomenology and technology.
The CSL Collapse Model and Spontaneous Radiation: An Update

A brief review is given of the continuous spontaneous localization (CSL) model, in which a classical field interacts with quantized particles to cause dynamical wavefunction collapse. One of the model’s predictions is that particles ``spontaneously’’ gain energy at a slow rate. When applied to the excitation of a nucleon in a Ge nucleus, it is shown how a limit on the relative collapse rates of neutron and proton can be obtained, and a rough estimate is made from data. When applied to the spontaneous excitation of 1s electrons in Ge, by a more detailed analysis of more accurate data than given previously, an updated limit is obtained on the relative collapse rates of the electron and proton, suggesting that the coupling of the field to electrons and nucleons is mass proportional. 1.

The recent realization that atom interferometers (AIs) can be used to test the gravitational redshift tests has proven to be controversial in some quarters. Here, we address the issues raised against the interpretation of AIs as redshift tests, reaffirming the fact that Müller et al. [Nature 463, 926 (2010)] indeed report a gravitational redshift test. 1
Simple Version of the Greenberger ± Horne ± Zeilinger (GHZ) Argument Against Local Realism
, 1999
"... Here is a simple, clear, useful proof that quantum mechanics contradicts Einstein, Podolsky, and Rosen ’ s local realistic assumptions. It is a variant of the powerful argument first worked out by Daniel Mordechai Greenberger, Michael A. Horne, and Anton Zeilinger. This version uses the eigenstates ..."

Here is a simple, clear, useful proof that quantum mechanics contradicts Einstein, Podolsky, and Rosen ’ s local realistic assumptions. It is a variant of the powerful argument first worked out by Daniel Mordechai Greenberger, Michael A. Horne, and Anton Zeilinger. This version uses the eigenstates of two orthogonal spin components for three spin1/2 particles. No operator or matrix algebra is necessary. A novel discussion of the background and history serves to introduce this proof and to place it in the context of Danny ’s work. 1.
