Integrated course unit module: PHYSICS AND STATISTICS

Learning objectives

The course of Physics has been designed to convey knowledge and understanding of basic physics principles and their application in practice. The topics are geared to concrete analysis and research problems.
The course will provide the necessary tools to address issues of increasing complexity preparatory to other major disciplines of the degree course, such as Chemistry, Biology,
Physiology, Biochemistry, etc.. , which are based on physical phenomenology.
The course will also provide the conceptual basis for understanding a number of major technologies that with increasing frequency are used in medicine, such as: centrifuges, endoscopes, microscopes, transducers for ultrasound equipment, laser systems, radiology equipment and NMR, radiation detectors, etc. In this sense, the module also aims to develop the students' attitude towards independent study and continuing education on the application of physical techniques to diagnosis and therapy in medicine.
As its final, but perhaps most important, goal, the course has been designed to stimulate students to become more familiar with certain common concepts, that are not always sufficiently explained in previous study, such as: mechanical action between bodies in contact, exertion
and energy in action, dynamic aspects resulting from elastic force and impact, friction and thermal and thermodynamic aspects, static and dynamic properties of gaseous and liquid fluids, light and its manifestations, including in relation to the structure of the eye and its physical defects, fundamentals of electrical, magnetic and nuclear phenomena, the laws that govern potential and current, electromagnetic and nuclear radiation, detection and control.


Course unit content

The course of Physics will deal with the most important aspects
of basic physics, from the definition of the main physical quantities and
measure systems up to the more complex content that are the basis of
diagnostic imaging and radiation therapy.
The course will cover the fundamental principles of mechanics, fluid
dynamics, electromagnetism, thermology, waves and optics.
Applications and consequences on human body physiology and medicine
will be stressed. In particular, deeper insights will be provided into
biomechanics, blood circulation, the use of radiations in diagnosis and

Teaching methods

Lectures will be held on-site in compliance with safety standards. Supporting material will be available on the specific, student-reserved platform (Elly) and will include slide presentations, audio-video aids or video-recording of the lectures.
During lectures, the topics contained in the program of the
module will be illustrated and commented. Emphasis will be posed on the
applications to biology and medicine of basic physics principles, with
examples of how such principles can lead to quantitative predictions on
physiological and pathological phenomena.
In selected cases, the demontration of basic physics principles will be
illustrated, with the aim to introduce the students to the practice of
logical thinking and experimental approach.

Assessment methods and criteria

The achievement of the objectives of the module will be assessed through a 1 hour written examination, mainly consisting in open questions on the topics of the course. This will allow to ascertain the knowledge and the understanding of both the theoretical bases and their consequences.
The written examination will possibly include the resolution of problems, to assess the achievement of the ability to apply the acquired knowledge to a simulated biological or medical situation. Calculators will be allowed, but not written texts or computer media. All parts of the written exam will be equally weighted in the final evaluation (in thirtieths).
The final mark, reported directly on Esse3, will correspond to the arithmetic average of the assessments obtained in the written test.
Students with disabilities, SLD, BSE must first contact Centro Accoglienza ed Inclusione (CAI) ( for support.
