Non-equilibrium Statistical Mechanics

~60 min · 15 stations

Non-equilibrium Statistical Mechanics is a self-paced learning path in Physics & Quantum Mechanics, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the primary differences between equilibrium states plus non-equilibrium systems; explain why entropy increases within isolated physical systems over time; contrast microscopic particle motion with observable macroscopic system properties.
