COURSE GOALS: The aim of the course is to familiarize students with recent developments in the theory of nonlinear conservative and dissipative systems in various fields of science (physics, biology, engineering, social sciences) with reference to the phenomenological, experimental and mathematical aspects of the analysis of such systems and their solutions.
LEARNING OUTCOMES AT THE LEVEL OF THE PROGRAMME:
Upon completing the degree, students will be able to:
1. KNOWLEDGE AND UNDERSTANDING
1.1 formulate, discuss and explain the basic laws of physics including mechanics, electromagnetism and thermodynamics
1.2 demonstrate a thorough knowledge of advanced methods of theoretical physics including classical mechanics, classical electrodynamics, statistical physics and quantum physics
2. APPLYING KNOWLEDGE AND UNDERSTANDING
