Why does Schr\"odinger's cat refuse to be quantic

Both at formal and philosophical levels, decades of efforts have been devoted to a deciphering of the `quantum enigma', the `crazy way quantum objects behave', to quote R.P. Feynman's words. We posit that the enigma cannot recede without resorting to a thorough questioning of the quantum ontology. In the current paper this questioning is introduced through a revisitation of the famous Schr\"odinger's cat paradox, and of the main attempts at solving it. Our proposal thereof, is that the quantum world enjoys a sound physical reality (complying, in particular, with the scientifc requirement of experimental reproducibility), but also, that this physical reality calls for an enlarged, and however precise notion of `what is real', such that what is real and actual can be distinguished from what is real but potential

Elementary Particles: What are they? Substances, elements and primary matter

The most successful "Standard Model" allows one to define the so-called "Elementary Particles". Now from another point of view, philosophical, how can we think of them? Which kind of a status can be attributed to Elementary Particles and their associated quantised fields? Beyond the unprecedented efficiency and reach of quantum field theories the current paper attempts at understanding the nature of what we talk about, the enigmatic reality of the quantum world.
