- Physics is not officially propedeutic for any other course. But I think it is very fair to say that the skills acquired in the Physics course allows the best assimilation of the concepts taught during the second year in the Physiology course, and in several other courses of the following years.

## Course objectives

The Student will acquire the tools of analysis necessary for a reasonable understanding of the physical phenomena involved in life sciences.

## Results of learning outcomes

The goal of the Physics teaching is to be able to correctly analyze and solve a complex problem, as experienced in clinics every day. Being able to use the Scientific Method and to handle easily order of magnitude calculations and factorization of solutions is the first goal. Once this is obtained, it is time to acquire the basics of all the physical laws that underlie medical phenomena. At the end of the teaching, Students will be able to use the physical laws and the mathematical tools all along most of the subjects that will be part of the Medicine and Surgery Course and Specialization School.

## Course delivery

The Course features formal lessons and exercise sessions:

- Each
**formal lesson**will describe theory and applications. At the end of each formal lesson, exercises will be delivered to Students, to be solved at home and to be loaded on the Moodle platform. **Exercise sessions**will feature the discussion about the exercises.**Webex sessions**will allow interactive Question-and-Answer concerning theory and exercises.

## Learning assessment methods

**Due to COVID, the Physics exams will be only oral**.

I very very strongly suggest you to**sit it as soon as possible**(June/July or, AT LATEST, September). It is important that you sit Physics before starting the second year, so that you can take advantage of the things we learn and that you will use in the other Courses. The sooner, the better!

Even if the exam modality has changed with respect to previous years, you must study the same way you would have done in our previous world, that is:**study the Theory****be sure to be able to apply Theory solving Exercises.**See them on Moodle (activities, assignments, written tests of previous years).

During the oral exam, I will ask

**3 questions**(**one of them on a subject chosen by you**). The 3 questions will start describing things as usual (as an example, I might ask: "Talk about Surface tension.") and during the oral**I will necessarily understand how you can manage the use of formulae and mathematics**at large (that is, how you would solve an exercise).**Any question**, please send me an email: roberto.cirio@unito.it- Oggetto:
