With the basic principles of thermodynamics introduced in part I, we now move on to the more statistical side of things. For many systems we can describe interesting properties using a statistical/probabilistic approach, intuitively linked to entropy and the occupation of states, such as certain energy states. Much of our time will be spent deriving distribution functions that underpin the relation between micro and macroscopic properties of systems, following in the steps of the greats like Einstein and Fermi. Using these tools we embark on attacking a wide variety of problems, from describing classical and quantum gases to exotic phenomena such as super-fluids and white dwarf stars.


Thermo and Mechanics II (ID: 014203) takes place in the spring/summer semester. Lectures are held in room 202 in Science Building 5 from 13:00 - 14:30 (3rd period) Thursday. The material will be the subject of seminars (read: tutorials) held immediately after each lecture.

If you wish to contact me my email address is: and I can be found in room 2-9-11 (Science Building 2, 9th floor, room 11).

The examples from the lectures can be downloaded from here. The Ising program I used to make the movies in lectures can be found here. Note that I encourage you to write your own rather than copy mine verbatim.
