Ristret

A project for the didactic innovation and the teachers’ training in quantum mechanics consists of two main phases: traditional main experiments (e.g.: Franck- Hertz, interference, polarisation); approach to Dirac to the theory. We outline a possible strategy to introduce the basic formalism of quantum mechanics without requiring an advanced mathematical or physical background. The “Dirac formulation” of Quantum Mechanics is developed by properly generalizing the description of a simple twostate system, namely the linear polarization of photons interacting with polaroids and birefringent crystals. We also discuss the relation between physical observables and linear operators, a connection which is usually considered as the “hardest” concept in Quantum Mechanics. A feasability study has been allowed by an experimentation in the fifth class of a Liceo.
