Learning outcomes of the course unit
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
