Some Developments in Newtonian Cosmology,f large density contrasts and peculiar velocity fields from a nearly structureless, uniformly expanding matter distribution. Comparing the properties of Newtonian models with those of their Einsteinian counterparts may also help to elucidate when and why relativity is genuinely needed.

,Poincaré Pseudosymmetries in Asymptotically Flat Spacetimes,xact flat-space symmetries. It thus seems reasonable to think of the pseudosymmetries as being . global symmetries for these weak gravitational fields. Presumably this idea can be extended to the associated concept of . conservation laws..Dedicated to Engelbert Schucking, who knows more mathematics and physics than most of us put together.

In the nonrelativistic limit, the translational gravitational moment of the Dirac field is found to be proportional to the spin covector of the electron.

The Physical Reality of the Quantum Wave Function,e and consistent to regard the wave function as but a convenient algorithmic device enabling observers to predict the response of quantum systems to observations. We briefly apply this point of view to demystify the well-known problem of Schrödinger’s Cat.
