Why does hot coffee only cool down and not heat up again on its own? The concept that explains this is entropy. While we commonly understand it as 'disorder,' in statistical physics, entropy refers to the 'number of possible outcomes.' Join Professor Kim Beom-jun of Sungkyunkwan University to explore why nature changes in one direction, as explained by entropy and the Second Law of Thermodynamics.
