The Physics lectures aim to give a basic knowledge of the whole physics of mechanics and electromagnetism, enough for the understanding of physical phenomena in biotechnology and in life science.
The lectures will have a strong applicative part with exercises in class in order to ease the comprehension of the theoretical concepts and to develop the ability in problem solving.

Examination Methods

The exam will be mainly written, with a number of exercises to be solved (typically 4 or 5) following the lectures' program and similar to those that will be done in class.

The professor reserves the possibility to add an oral consultation, or in particular in the case in which the student is very close to the sufficiency without obtaining it, or in case there is any doubt about the actual evaluation of the student or even in the case where there is doubt or suspicion that the student has copied.
