This is a video of part of a lecture course in thermal and statistical physics I taught at the Catholic University of Korea in 2013.

This lecture includes:
 - definition of the ideal, spin 1/2 paramagnet (0:00)
 - entropy of the ideal paramagnet - calculation (5:28)
 - Stirling's approximation (10:05)
 - entropy of the ideal paramagnet - result (19:08)
 - temperature of the ideal paramagnet (21:25)
 - discussion of negative temperatures (29:05), (34:08)
