About the role of chaos and coarse graining in statistical mechanics

• We discuss the role of ergodicity and chaos for the validity of statistical laws.
• We explore the basic aspects of chaotic systems on systems composed of a huge number of particles.
• We emphasize on the finite-resolution aspects.

We discuss the role of ergodicity and chaos for the validity of statistical laws. In particular we explore the basic aspects of chaotic systems (with emphasis on the finite-resolution) on systems composed of a huge number of particles.
