# Fundamentals of Physics: Thermodynamics and Entropy

## Thermodynamics and Entropy

The focus of the lecture is the concept of entropy. Specific examples are given to calculate the entropy change for a number of different processes. Boltzmann's microscopic formula for entropy is introduced and used to explain irreversibility.
