A methodological note on proving agreement between the Elementary Process Theory and modern interaction theories
The Elementary Process Theory (EPT) is a collection of seven elementary process-physical principles that describe the individual processes by which interactions have to take place for repulsive gravity to exist. One of the two main problems of the EPT is that there is no proof that the four fundamental interactions (gravitational, electromagnetic, strong, and weak) as we know them can take place in the elementary processes described by the EPT. This paper sets forth the method by which it can be proven that the EPT agrees with the knowledge that derives from the successful predictions of a modern interaction theory T. This determines a fundamentally new research program in theoretical physics
Symmetries in Physics: Philosophical Reflections
This is the introductive paper to the volume "Symmetries in Physics:
Philosophical Reflections", Cambridge University Press, 2003. We begin with a
brief description of the historical roots and emergence of the concept of
symmetry that is at work in modern physics. Then, in section 2, we mention the
different varieties of symmetry that fall under this general umbrella,
outlining the ways in which they were introduced into physics. We also
distinguish between two different uses of symmetry: symmetry principles versus
symmetry arguments. In section 3 we make some remarks of a general nature
concerning the status and significance of symmetries in physics. Finally, in
section 4, we outline the structure of the book and the contents of each part.Comment: 16 pages. To appear in K. Brading and E. Castellani (eds.),

Quantum Structure in Cognition, Origins, Developments, Successes and Expectations
We provide an overview of the results we have attained in the last decade on
the identification of quantum structures in cognition and, more specifically,
in the formalization and representation of natural concepts. We firstly discuss
the quantum foundational reasons that led us to investigate the mechanisms of
formation and combination of concepts in human reasoning, starting from the
empirically observed deviations from classical logical and probabilistic
structures. We then develop our quantum-theoretic perspective in Fock space
which allows successful modeling of various sets of cognitive experiments
collected by different scientists, including ourselves. In addition, we
formulate a unified explanatory hypothesis for the presence of quantum
structures in cognitive processes, and discuss our recent discovery of further
quantum aspects in concept combinations, namely, 'entanglement' and
'indistinguishability'. We finally illustrate perspectives for future research.Comment: 25 pages. arXiv admin note: text overlap with arXiv:1412.870
