I believe that an improved approach to teaching thermodynamics can be created by starting with the atomic theory of matter and then explaining the connections between this theory and macroscopic thermodynamic phenomena. This micro-to-macro approach arguably began in the late 19th century when a small group of scientists, namely Rudolf Clausius, James Clerk Maxwell, andContinue reading “The Road to Entropy – The kinetic theory of gases & heat capacity”

## The Road to Entropy – Clausius, Gibbs, and increasing entropy

At the conclusion of his famed 1865 paper announcing the discovery of a new property of matter that he named entropy, Rudolf Clausius stated: the entropy of the universe tends to a maximum. This statement came as a total surprise to me as there was no prior supportive discussion behind it, and it had meContinue reading “The Road to Entropy – Clausius, Gibbs, and increasing entropy”

## The Road to Entropy – Clausius undaunted

Have you ever experienced that wondrous “Eureka!” moment of insight when you’ve discovered some hidden secret of nature? Archimedes did when he realized that the volume of water displaced is equal to the volume of the body submerged. KekulĂ© did when discovered benzene’s structure. Hubble did when he discovered that the stars are all movingContinue reading “The Road to Entropy – Clausius undaunted”

## The Road to Entropy – James Joule and the power of his curiosity (video)

James Joule could have observed what he did and then done nothing with it. Instead, he became driven to understand and explain it and so discovered the mechanical equivalent of heat, a forerunner of the concept of energy and the 1st law of Thermodynamics. His story is a good one, an inspiring one, an exampleContinue reading “The Road to Entropy – James Joule and the power of his curiosity (video)”
