Readings/Bibliography
Texts/Bibliography
The lecturer makes the material used in lectures for the theoretical part and exercises available online.
Fundamental will be the use of a reference text, among several available in university libraries:
· E. Ragozzino, “Elementi di Fisica”, Edises.
· Castellani G, Remodni D, “Elementi di Fisica in Medicina e Biologia”, Bononia University Press
· Scannicchio D. “Fisica Biomedica”, Edises (per un livello più approfondito)
· L. Nitti, "1000 DRSM di Fisica", Casa editrice Ambrosiana.
Teaching methods
Teaching Methods.
Blackboard lectures, PowerPoint slide show, tutorials.
Assessment methods
Final written quiz test with possible oral integration. The written test consists of 24 multiple choice questions, 12 theory and 12 exercises. The total score allows the achievement of 30/30 with honors.
Teaching tools
Classroom lectures will be supplemented by the guided performance of exercises. The final lecture will partly cover a mock examination with multiple choice questions.
