Obiettivi formativi
The course aims to provide students with a comprehension of the development of physics in the twentieth century through a study of some historically significant cases. The course may be useful for the conception, organization and coordination of cultural activities and projects concerning the history of physics and its relationships with philosophy.
Risultati apprendimento attesi
Knowledge and understanding
At the end of the course, the student
- knows the fundamental elements of the development of physics during the twentieth century
- knows the details, including some mathematical demonstrations and experimental results, of some important discoveries in physics achieved during the twentieth century
- understands the relationships between the history of contemporary scientific thought and the history of philosophy and the philosophy of science

Ability to apply knowledge and understanding
At the end of the course the student
- can apply the knowledge acquired in situating authors and texts historically
- can apply the scientific lexicon of the twentieth century to the analysis and discussion of texts and problems
- can apply the understanding of the historical relationships between science and philosophical doctrines to the analysis and discussion of texts and problems.

Programma
Quantum mechanics, which describes the behavior of subatomic particles, seems to challenge common sense. Waves behave like particles; particles behave like waves. You can tell where a particle is, but not how fast it is moving — or vice versa. An electron faced with two tiny holes will travel through both at the same time, rather than one or the other (really so?). And then there is the enigma of creation ex nihilo, in which small particles appear with their so-called antiparticles, only to disappear the next instant in a tiny puff of energy. Since its inception, physicists and philosophers have struggled to work out the meaning of quantum mechanics. Some, like Niels Bohr, have responded to quantum mechanics' mysteries by replacing notions of position and velocity with probabilities. Others, like Einstein and Penrose, have disagreed and think that the entire puzzle reflects not a fundamental principle of nature but our own ignorance of basic scientific processes. The book by Ghirardi that we will comment offers a deep and real understanding of the problems inherent to the interpretation of quantum mechanics. The course will present a balanced overview of the development of the philosophy of quantum mechanics from the times of Planck and Einstein up to the seminal papers published in 1935 by Einstein, Podolsky, Rosen and Schrödinger and will explore how the theory of quantum mechanics was interpreted in conflicting ways by Einstein and Bohr.


Online platform used: Ariel.

No streaming of lectures available, unless the classroom is fully booked (which is very unlikely for this course)

Some recordings covering key concepts will be made available until the end of the course. I will upload the recordings on Ariel.

For those who cannot attend: you will be able to participate via Teams to two lectures delivered online on the 16th and the 23d of November. These lectures will be part of the discussion of suggested readings

This program is valid for one academic year, according to the rules established for this course of studies.
Prerequisiti
A high-school (final year) background in physics (esp. Newtonian mechanics and electromagnetism)
Metodi didattici
The first 40 hours will consist in lectures delivered by the instructor. Useful information and slides will be uploaded to the MyAriel platform. The last 20 hours will consist in presentations based on the suggested readings (see Materiale di Riferimento) organized by the students.

Modalità di verifica dell’apprendimento e criteri di valutazione
Assessment methods

Both for students who have attended the course and for those who haven't the final examination consists in an oral exam.

The purpose of the oral exam is to test the knowledge and the critical comprehension, of the topics covered in the works indicated in this programme in the field "materiale di riferimento", and the fact that the student has acquired the correct linguistic skills to express and discuss these topics.

Evaluation criteria:

The oral exam is divided into two parts. In the first part the instructor will propose a topic to the student. In case the answer of the student is considered sufficient (18/30), the exam will continue with a discussion on a topic chosen by the student. All topics must be part of the programme taught during the course and included in the reference material ("materiale di riferimento"). A mark will be obtained on the basis on the following criteria (1 to 10 points: factual information + 1 to 10 points language skills, + 1 to 10 points understanding of technical/ scientific content).
