This lecture serves as an introduction to statistical physics, providing a different perspective on thermodynamic concepts. The instructor discusses fundamental assumptions, such as the number of configurations and Boltzmann's entropy definition. Topics include isolated system statistics, ideal gas law derivation, Boltzmann distribution, kinetic theory of gases, equipartition principle, calorimetric coefficients calculation, two-level systems, specific heat of water, latent heat of vaporization, and entropy-disorder relationship.
