Is nature OO?
  What exists "out there"? What does "doing physics" mean? What are the axiomatic ideas for microphysics? What is a particle? What is an apparatus made of? We show that Quantum Mechanics textbooks cannot truly answer this kind of question whereas they should. By adopting a pure "hitological" point of view for microphysics, we introduce the Hit in Apparatuses Theory (HAT) and the Vacuum of Apparatuses (VA) that restore, through Object Orientation (OO), an intuitive ontology to deal with this kind of physics. Through a review of what it means to "observe" and what relativism means in Special and General Relativities (SR and GR), we address the problem of finding common maths for GR and QM. Finally, with our new HAT, we address the measurement problem in QM and propose two possible approaches.
