COURSE GOALS: Course goals are to acquire theoretical and experimental knowledge of the basics in statistical physics and thermodynamics, gaining operational knowledge of the methods for solving numerical problems in statistical physics and thermodynamics, and achieving skills of reducing the real problems in statistical physics and thermodynamics to a physical model, with setting up the appropriate equations.
LEARNING OUTCOMES AT THE LEVEL OF THE PROGRAMME:
1. KNOWLEDGE AND UNDERSTANDING
1.1 formulate and interpret the basic laws of physics including mechanics, electromagnetism and thermodynamics
2. APPLYING KNOWLEDGE AND UNDERSTANDING
2.1 develop a way of thinking that allows the student to set the model or to recognize and use the existing models in the search for solutions to specific physical and analog problems
2.2 recognize analogies in the situations that are physically different, as well as in the situations analogous to the physical ones, as well as applying known solutions when solving new problems
5. LEARNING SKILLS
5.1 consult professional literature independently as well as other relevant sources of information, which implies a good knowledge of English as a language of professional communication

REQUIREMENTS FOR STUDENTS:
Students are required to regularly attend lectures, seminars and exercises, and actively participate in solving problems during exercises. Furthermore, students are required to pass two colloquiums and four tests during the semester, and to achieve at least 33% of the total number of points on them.
GRADING AND ASSESSING THE WORK OF STUDENTS:
The final exam consists of written and oral examinations, final score is the average value of grades obtained on each of them. Additional points can be achieved by successful solving homework assignments and prize tasks. Written exam can be replaced by a successful solving of two colloquiums.
