PHYSICS - channel 1

Provide the student with the wealth of knowledge necessary to face the most specific courses in the curriculum; the course containes various applications in the biomedical field, normally omitted in physics courses. The discussion of the various topics is formally correct, while remaining within the mathematical knowledge acquired by the students in previous courses.

Frequency of the course of Mathematics Institutions is recommended
