the notion of `aether`: hegel versus contemporary physics
... Beyond mere observations and collections of data the work of science is to a large extent the formulation of theories in the context of which those observations and data become meaningful [3](chpt. 7). Theories, however, cannot be found as objects in nature. As inhabitants of Popper's well-known Wor ...

A Hubbard-Stratonovich transformation is used to trade a generic quartic contact interaction in favor of dynamical Dirac mass-like bilinears coupled to their conjugate fields (that will be called dynamical Dirac masses). These dynamical Dirac masses may violate any symmetry constraint other than the ...
