# Quantum Mechanics

## Objectives

Quantum Mechanics is undoubtedly one of the most beautiful creations of the human mind in the XX century. Being part of the continuous search for the truth and the understanding of the real world, this construction, laboriously built along a few decades by some of the greatest physicists of the time, shoed itself as a consistent theory that allowed for the interpretation of existing experimental results and previewed other. Knowledge of contemporary physics, even at a not too high level, asks for acquisition of the basis of quantum mechanics.

In this course, the student will acquire the fundamental concepts where lies the quantum treatment of a large number of problems of modern physics.

After approval in this course, the student will be able to deal with both theoretical and applied problems that will ask for a quantum theory basis.

The mathematical methods that will be used, mostly in the algebra domain, should have been acquired beforehand, but will be reviewed.
