Założenia (opisowo)

The students entering the course are expected to have completed an introductory course on statistical physics and thermodynamics as well as the standard undergraduate level courses (classical and quantum mechanics, electrodynamics). Some knowledge of fluid mechanics and stochastic processes is useful.

Efekty kształcenia

The student will have a working knowledge of how to apply statistical mechanics in and out of equilibrium.

Kryteria oceniania

- Hand-in exercises (5x, 10%), Mid-term exam (written, 30%), Final exam (written, 60%).

- In retake session one can base the grade on just the final exam and the oral exam.

- In order to pass the course it is required to have more than 50% of the attainable points of the final exam.
