Elementary algebra and differential calculus.

The course aims to train students for the scientific method and how to learn and understand the methodologies of physics.In particular, it aims to enable students to acquire the ability to solve classical physics problems by understanding, reasoning, and calculating.At the end of the course, students should have basic theoretical knowledge on the topics of the program and should be able to solve both exercises and more complex problems.

-Halliday-Resnick, di Jearl Walker:"Fondamenti di Fisica"Volume unico, settima edizione, Casa Editrice Ambrosiana-Slides of the lectures-Additional material provided by the lecturer

Lectures in which the topics of the program are exposed and discussed. During the lectures, the solution of specific exercises and problems is addressed for each topic.

Verification of learning involves a written test lasting two hours divided in two parts.The first part consists of questions with multiple answers aimed at verifying the theoretical knowledge acquired on the various parts of the program.The second part provides for problem solving and testes the acquisition of methodological and calculation skills applied to physics. It is given the opportunity, after passing the written test, of a further oral examination concerning both the knowledge and the methodology.

- Tutoring is offered to students.

- Attendance at lessons is recommended for the uniqueness of the educational experience that takes place in the classroom.

- Notices and supplementary teaching materials are available on a google drive managed by the teacher and the address of which is communicated to the students during the first lesson.

- The reception can be arranged according to the specific needs of the students.

- Students are reminded to always use their @unisi e-mail address and to always sign (name, surname and serial number) correspondence with the teacher.
