Syllabus
01
Entropy: counting the ways
Macrostates, microstates, and Boltzmann's S = k_B ln W — the counting argument behind the second law.
0%
+
02
The Boltzmann distribution
Why e^(−E/k_BT): deriving the Boltzmann distribution from the counting argument.
0%

03
Partition functions
The partition function Z: the single sum that generates every thermodynamic quantity.
0%
+
04
Ideal gases, statistically
The ideal gas rederived from statistics: pressure, energy, and the equipartition theorem.
0%
+
05
Quantum statistics
Bose–Einstein and Fermi–Dirac statistics — how indistinguishability reshapes counting.

06
Phase transitions
Phase transitions, critical points, and the Ising model.
0%
