The course is aimed to provide the student with the basic elements of some physics topics and to describe the methods of physics applied to biological data. At the end of the course, the student will be able to schematize a phenomenon in terms of physical quantities. The student will apply the scientific method to the study of natural phenomena and will be able to critically evaluate similarities and differences between physical systems.
To develop statistical and methodological abilities applied to the analysis of biological/biomedical events. To develop abilities to apply the principal tools of statistical data collection, measurement and analysis.
The teaching method is based on lectures and exercises. Should the circumstances require online or blended teaching, appropriate modifications to what is hereby stated may be introduced, in order to achieve the main objectives of the course.
The course includes lectures in which continuous interaction with students and exercises in the multimedia classroom is encouraged, using specific statistical software, with examples to apply the
knowledge acquired during the course.
Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
Learning assessment may also be carried out on line, should the conditions require it.
