Previous knowledge of classical mechanics and thermodynamics is assumed in the lectures. The students are also expected to comfortably master basic algebraic tools at the level of the courses Matemaattiset apuneuvot and Fysiikan matemaattiset menetelmät I.

The course is bilingual: lectures are given in Finnish, but the homework problems are provided in English. The lecture notes and course book are both in Finnish, but handwritten notes in English (from a previous year) as well as a list of international textbooks are provided below. It will be possible to take the final exam in either language.

**NB: While the course has now ended, the follow-up course Quantum Statistics will commence on Monday, March 12.**

Mondays and Tuesdays 12.15-14.00 in A315. The first lecture takes place on January 15.

Lecturer: Aleksi Vuorinen, A322, aleksi.vuorinen@helsinki.fi.

The course book is Statistinen fysiikka (J. Arponen and J. Honkonen, Limes ry, 2000). Additional recommended reading includes:

- R. Bowler ja M. Sanchez: Introductory Statistical Mechanics, Clarendon Press, 1999
- K. Huang: Statistical Mechanics, Wiley, 1987
- L.D. Landau ja E.M. Lifshitz: Statistical Physics, Pergamon, 1980

Fridays 10.15-12.00 in C129 (Exactum). The first exercise session takes place on January 26.

Teaching Assistant: Pyry Wahlman, C311, pyry.wahlman@helsinki.fi.

The home work problem sets are published on this page on Tuesdays: Problem sets 1, 2, 3, 4, 5, 6. Written solutions should be returned either directly to the lecturer or to his mailbox by the Tuesday of the following week. The solutions are graded, and they make up 1/4 of the final grade of the course.

The course results are now available here.
