|SCIENTIFIC DISCIPLINARY SECTOR||FIS/07|
Physics is a fundamental science that has as its object the understanding of natural phenomena and whose purpose is to provide the tools to be able to predict them in a quantitative way. It is the basis from which other sciences and technology develop.
Physics plays an important role in the field of cultural heritage and their restoration as it provides the basis for the development of relevant technologies for diagnostics, conservation and restoration.
The aim of the course is to provide students with the basic knowledge of physics, sufficient to understand the physical methods applied to the conservation and restoration of cultural heritage.
Attendance and participation in didactic activities will allow the student to acquire basic knowledge necessary to face studies in the field of Conservation and Restoration of Cultural Heritage.
At the end of the first module the student will be able to:
- correctly express the result of a physical measurement and understand the meaning of reliability of a measurement and statistical distribution
- know and use the main physical laws of mechanics, electromagnetism and optics
-apply the knowledge acquired to simple physical systems
at the end of the second module the student will be able to:
- know the main diagnostic techniques for the analysis of an artifact
-know the physical principles underlying the diagnostic techniques
To effectively deal with the contents of the course, the following basic knowledge of elementary mathematics is necessary:
Representation of a function in the Cartesian plane
Elements of trigonometry
The teaching consists of lectures and exercise sessions on the topics.
The lectures are delivered through multimedia presentations.
During the exercise sessions, the participation of students in the definition of the strategy to reach the solution of the problem and the critical analysis of the results obtained is strongly encouraged.
Attendance at lessons and exercises is strongly recommended.

The exam consists of a written part relating to the first module and a paper on a topic agreed with the teacher of the course relating to the second module.
The written exam, relating to the topics covered in the first module, is passed if the student obtains a mark greater than or equal to 18/30 with the possibility of recovery for the parts not passed.
6 exams will be available for the written test starting from the end of the first semester.
The dissertation, to be discussed orally before the Exam Commission after the student has passed the written part of the exam, must be presented in writing to the members of the Commission one week before the discussion and is passed if the student obtains a mark greater than or equal to 18/30.
The final mark is given by the arithmetic mean between the mark of the written test and the oral exposure of the thesis.
Details on the methods of preparation and the degree of detail required for each topic covered will be provided during the lessons.
The written exam (first module) will verify the actual acquisition of the concepts relating to data processing and physical laws. The student must demonstrate that he has acquired these concepts by applying them to simple physics problems and that he is able to use dimensions and units of measurement of physical quantities appropriately.
The paper (second module) must highlight how the student has understood the potential of one or more diagnostic techniques by highlighting the results they are able to provide and their limitations also through the application to the study of a specific object.
