Learning Objectives

The provided knowledge enables the student to face the most specific courses of the study plan; a particular importance is given to the contribution of physics in its biomedical field applications included in the program. At the end of the course, the student will have learned the experimental method fundamental elements, the basic laws of physics and their different applications to the fields concerning the study plan. The formal correctness in the exposition of the treated subjects is particularly taken into account with regards to mathematical knowledge acquired from the student in his previous courses. The goal is the achievement of the following training objectives: - a knowledge and a capacity comprehension on physics foundations – practical competencies concerning methodological and instrumental procedures also useful in biological field research.


Course Structure

Lectures and examples of application on specific topics are planned. The lectures will focus on methodological content of the discipline for some topics covered in the course and application contents for the majority of topics covered. The students will actively deepen the applicative contents during some lessons that will take place in the Physics Laboratory of the Department of Physics and Astronomy.
