NANS7018 NANO3/PH5: From Classical to Quantum Mechanics (JSS35) (1 cr)

The course follows the transition from classical to quantum mechanics, beginning with Planck's quantization and the early attempts to preserve classical reasoning. We examine the key problem cases that exposed the limits of classical ideas, including the Compton effect and the development of atomic theory through Bohr and Sommerfeld, with emphasis on scientific logic and the role of models, approximations, and experimental evidence during the transition period. The course concludes with the decisive conceptual shift to Heisenberg's matrix mechanics, and with Schrödinger's later reflections on entanglement that opened a new way of thinking about what physical theory can say.

After passing the course, students should have an understanding of events that have led to quantum modern physics, mutual interrelationships between different actors in developing the new physics. Students also have an overall idea of the cultural context in which new ideas emerged. The evaluation is based on three exercises (in groups) during the course.
