Learning objectives
The course gives, with a simplified approach, some basic concepts which are necessary to some of the following biology and chemistry courses. In particular, the contents of the present course offer a physical description of the mechanisms underlying many processes relevant for chemistry and biology
Knowledge and understanding
The student should prove to know and understand some of the most important aspects of classical physics, and of the physical laws controlling them.
Applying knowledge and understanding
The student should be able to understand similarities and differences between physical systems, and to comprehend physical laws. The student should be able to comprehend the essential aspects of physical laws, perform independently simple exercises, analyze the data and summarize the problems in their essential aspects.
Making judgements
Students, at the end of the course, will have to demonstrate that they have improved their critical thinking skills and judgment capability in particular to interpret data, elaborate on natural phenomena, communicate ideas-problems-solutions in order to develop the learning skills that are necessary to undertake further studies in biophysics or carry out professional activities related to it.
Learning skills
Students, at the end of the course, will have to demonstrate that they have started a path of understanding of the main classical physical issues, identification of the physical laws behind natural phenomena, comprehension of the most recent research results and translation into professional actions, that should be considered as self-study.
