This course has the primary objective to provide the knowledge on the basic laws of physics and the capacity (i) to apply them to explain the main phenomena of biological and medical interests; (ii) to get the necessary background to explain the functioning of the human body and the sources of some pathological conditions; (iii) to gain the basics to understand the operation of the main medical devices. We refer to the next section for a more detailed list of topics covered during the course.
At the end of the course the student should be able to analyze and explain the main biophysical processes of the human body by exploiting physics laws. Skills in problem solving are acquired during the course.
Additionally, the student should develop a critical attitude in assessing the validity of physical models adopted to describe the biomedical phenomena. Furthermore, the student should be able to insert the physics concepts
within a precise and rigorous framework, possibly establishing and deepening connections among different topics.

Optical systems for the correction of vision defects, ultrasound systems for therapy and diagnosis.
Stand-up lectures and practice.
Written tests during the course to improve the self evaluation attitude
During the lectures students will be strongly involved essentially in two stages:
1) Summary of the previous lecture: groups of students discussed the main items of the previous lecture and a group will be selected to present them. Short discussion will follow. Totally, this will last 5-7 minutes at the beginning of the lecture;
2) Questions during the lecture: answers to the questions will be given by groups of students or by each single student.
By adopting this strategy it is possible to check student comprehension and ability to catch the essential points of the lecture. Additionally, every 10 days students will receive a homework. If the homework is positively solved, the mark will contribute to the final note.
About 10 hours will be devoted explicitly to exercises, although each main topic presented during the lectures will be integrated by examples.
Lectures will be delivered mainly face-to-face. Online integrations and explanations are also possible in order to strength the attendance.
Verification of learning
Evaluation of the exam will be done according to
-Mandatory written exercises on the basic topics; the vote in this test, at the discretion of the commission, may preclude admission to the next oral exam made by audits on applied physics.
-During the teaching period two written exercise sessions can substitute the exercises before the audits.
-A mandatory oral test on physics topics considered during the course.
Overall score expressed as 18-30/30 based on the following items:
Quality of knowledge and mathematical skills:
a) suitability and accuracy of the skills;
b) suitability and accuracy of the proficiency;
c) suitability and accuracy of the expertise.
b) Use of the proper technical jargon;
c) Ability of establishing logical connections between different topics and aspects;
d) Capacity for synthesis.
The evaluation is:
a) Passing (from 18 to 20/30)
The student explains few concepts with several shortcomings but a sufficient expressiveness; shallow logical ability and poor capacity for synthesis; poor interaction with the lecturer during the oral test.
b) Fair (from 21 to 23/30)
The student shows a fairly broad spectrum of knowledge, but she/he demonstrates a poor deepening attitude; knowledge gaps are limited; fair ability in establishing connections between different items and in answering questions; fair capacity for synthesis.
c) Good (from 24 to 26/30)
The students demonstrates a good knowledge of the topics with few gaps; good expressiveness and capacity for synthesis; good mastery of scientific terms and concepts also via graphical interpretation.
d) Very good (from 27 to 29/30)
The student manages a manifold of physical concepts, which she/he has deepened; very few minor gaps are identified; very good interactive ability and remarkable attitude toward links between different topics; relevant capacity for synthesis and graphical elaboration.
e) Excellent (30/30)
In addition to a very broad spectrum of competence in physics, the student has an excellent expressiveness and manages the proper scientific jargon; topics are approached with the appropriate criticism and connections are well identified; great propensity to the use of mathematical and graphical tools to solve problems.
Honours are are granted to students that have perfored well above the average; possible gaps in knowledge and logical attitude as well as lack of proper jargon are irrelevant.
