## Learning Objectives

The purpose of the Applied Physics course is to teach basic physics and mathematics with simple applications to biomedical problems. The homogeneity of the preparation for all students is to be obtained in view of the specific knowledge required in the continuation of the Degree Course. In particular, the student must acquire knowledge of some basic laws and physical techniques for the understanding of physiological, biological and medical processes and will have to learn basic concepts useful for the correct use of the instrumentation used in the professional field.
