📢 Comment Event Leave a comment sharing your thoughts on the show or topics you’d like 【My Hobby is Science】 to cover! We will randomly select winners to receive a copy of *Boltzmann’s Atom*, a book recommended by Professor Kim Beom-jun. ✅📢 Participation Period: July 11 (Sat) ~ July 19 (Sun) ✅📢 Winner Announcement: July 20 (Mon) Check the pinned comment! 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. ▶ Watch Again https://home.ebs.co.kr/ebsscience/main *You can also watch "Hobbies are Science" by searching on Wavve, TVING, and Watcha. ▶ Recommended Programs to Watch Together EBS 【My Second Textbook Thermodynamics, Understanding Entropy Most Easily 】 EBS 【Knowledge Channel e Quantum Information Series 2-Part Series】 EBS 【DocuPrime Physics of Light Part 3 – The Light Tracker 】 Timeline 00:00 Start 01:13 The Science World's Top Instructor to Explain Entropy Easily 03:24 The Microscopic Basis of Thermodynamics, Statistical Mechanics 04:20 Entropy Defined in Statistical Physics 05:05 The Number of Microscopic States, ‘Probability’ 06:59 Is the Expression ‘Disorder’ Correct? 08:54 The Question Created by the 19th-Century Industrial Revolution 11:15 What Is the Difference Between Heat and Energy? 12:25 The First Law of Thermodynamics, Conservation of Energy 15:15 The Birth of a New Physical Quantity, Entropy 17:07 Clausius Explains the Direction of Change 22:03 The Question That Ultimately Remained: ‘Why’ 22:49 Boltzmann Fills in the Blanks of Entropy 23:22 Are Boltzmann’s Six Great Disciples in Korea? 24:24 From Macro to Micro, Boltzmann’s New Perspective 25:22 Entropy Explained by Molecular Movement 28:18 Can Miracles Really Not Happen? 28:48 Conditions for the Law of Entropy Increase 31:33 Can Time Flow Backwards? 32:02 The Secret of ‘S’ in the Boltzmann Formula 33:00 Why Logarithms Are Necessary 33:50 The Boltzmann Formula Connecting the Micro and Macro 35:29 [Unreleased Footage] What Epitaph Would I Like to Leave Behind? 36:59 Does Life Defy Entropy? 38:26 Does This Law Hold in the Universe? 39:35 Maxwell's Demon Thought Experiment 42:01 The Tragedy of Boltzmann, Ahead of His Time 44:57 Boltzmann's Legacy 100 Years Later 47:23 Next Story #ScienceIsASociety #ScienceIsASociety #Science #ScienceTalk #ScienceTalkShow #Defconn #Star #LeeDaehan #JangHongje #KimBeomjun #Entropy #Thermodynamics #StatisticalPhysics #Disorder
