Environmental Physics ElementsAcademic Year 2022/2023 - Teacher: LUCA LANZANO'
Expected Learning Outcomes
The course aims to provide students with basic knowledge of physical methodologies that can be used in applied contexts of cultural heritage, environment, biology and medicine: knowledge of the origin, provenance, characterisation and dating of archaeological and historical-artistic interest artworks; knowledge in the radioactivity field and their implications in the environmental field; knowledge of theories and methods of physics for understanding how biological systems function; knowledge of methodologies applied in the medical field within of diagnostic systems, radiation therapies and radiation protection from ionising and non-ionising radiation.
Knowledge and understanding
Critical understanding in applied physics field in both theoretical and laboratory aspects and their interconnections, also in interdisciplinary fields. Considerable knowledge of the scientific method, understanding of the nature and procedures of research in the field, knowledge of the experimental aspect with particular reference to the choice of methods for different applications.
Capability to apply the knowledge in order to:
· Identify the essential elements of a phenomenon, in terms of order of magnitude and level of approximation required, and be able to make the required approximations.
· use the tool of analogy to apply known solutions to new problems (problem solving).
· design and implement experimental and theoretical procedures for new measurements or the improvement of existing results.
Autonomy of judgment
Ability to work with increasing degrees of autonomy, including assuming responsibilities in the planning and management of projects. Awareness of safety issues in laboratory work. Ability to argue personal interpretations of physical phenomena, confronting each other in working groups. Development of a sense of responsibility through the choice of optional courses and thesis topic.
Ability to communicate in the specific fields of Physics. Ability to present one's own research activity or review both to an expert and to an non-expert audience. Ability to work in an interdisciplinary team, adapting modes of expression to interlocutors of different cultures.
Ability to acquire adequate cognitive tools for the continuous updating of knowledge. Ability to use databases and bibliographic and scientific resources to extract information and insights to better frame and develop one's own study and research work.
Frontal and theoretical-practical lectures, seminars for all 6 CFU.
Cooperative teaching (student-teacher) by sharing teaching materials and multimedia aids. If the course is taught in a blended or distance learning mode, the necessary variations may be introduced with respect to what has been previously stated, in order to comply with the syllabus.
Knowledge of General Physics and elements of Modern Physics.
Attendance of LessonsAttendance at the course is normally compulsory (please refer to the Course Regulations).
