Syllabus
Prerequisites: Mathematical Analysis 1,2,3, Geometry, General Physics 1,2.
Target skills and knowledge: The course highlights the experiments and the theoretical issues underlying the scientific revolution that replaces classical mechanics and electromagnetism with special relativity and quantum mechanics. In the first part we introduce special relativity, discussing its origin, the logic of its structure and the innovative features of its consequences. In the second part we discuss the experimental findings leading to the concept of quantization and we introduce the basis of quantum mechanics and atomic physics.
Examination methods: Written and oral examination
Assessment criteria: To evaluate the understanding of the theoretical concepts and to check the ability of solving exercises related to the topics of the course.
Course unit contents: First Part: Special Relativity. Galilean transformations. Galilean Relativity. Electromagnetism and galilean relativity. The Michelson-Morley experiment.
