Examination methods:

Oral exam 
Assessment criteria:

Knowledge of the course material and ability to independently present and interpret it. 
Course unit contents:

The course presents, at an advanced level, some of the main subjects of the physics of fluids and plasmas.
During the course examples and applications from both astrophysics and controlled fusion will be presented.
