(although the lecturer will follow the Italian edition edited by G. Vannini, foreign students may use the original English edition; content is practically the same)
The lectures will be based on the qualitative explanation of the treated physical phenomena followed by their analytical description in order to quantitatively and formally describe it (computer and blackboard will be both employed). In order to strengthen and clarify the main concepts of the lesson (1) brief exercises will be proposed, as well as (2) videos with focused experiments will be showed and discussed during the class. The additional material (e.g., slides, videos, supplementary exercises) will be shared with the students through the Elly platform.
Moreover, dedicated lessons for the resolution of more complicated exercises will be carried out with the help of an assistant.
Assessment methods and criteria
Three written tests will be carried out during the semester. The tests will take place roughly every four weeks and will focus on the corresponding part of the didactic program. Access to these partial tests is allowed to students of the first year, as well as to students from previous matriculation years only if they regularly attend the lectures.
Students who passed the three partial tests, or failed one of them, however maintaining an average mark of at least 16/30, will be automatically admitted to the oral exam.
Those students who failed the partial tests, as well as students from previous academic years, have to go through a general written test, with exercises on the entire program (six problems to be solved in three hours), and get at least 16/30 in order to be admitted to oral exam.
The final mark approximately accounts for 1/3 of the result of written test(s) and 2/3 of the result of oral exam.
