APPLIED PHYSICS (B)
Learning outcomes of the course unit
Provide basic physical tools to approach issues of increasing complexity; introduce the student to the study and application of the scientific method, the basic research tool in any field of science; illustrate the most significant aspects of natural phenomena, with particular reference to the measurement of magnitudes that comprise them; describe, within a context of logical continuity, the most common physical properties that provide support and interpretation for biomedical-related magnitudes.
