Teaching Methods
Teaching is based on the expositive method with constant references to physics systems to which the concepts learned are applied to. There is also a particular emphasis on learning the mathematical techniques needed to derive the properties and relantionships between the several quantities associated to the equations and their solutions of Relativistic Quantum Mechanics. When appropriate, students are also interrogated regarding concepts exposed or the derivation of mathematical relations, such that they can reach the correct conclusions by themselves.
