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)”

The Road to Entropy – Sadi Carnot’s use of analogy to create his “flawed” masterpiece (video)

The commercialization of the high-pressure steam engines by the Cornish Engineers of Britain inspired Sadi Carnot, a French military engineer, to analyze these engines and seek the theories to guide their improvement. If you’re interested in doing a deep dive into Sadi Carnot’s work, here are two excellent references. I go into much more depthContinue reading “The Road to Entropy – Sadi Carnot’s use of analogy to create his “flawed” masterpiece (video)”

The Road to Entropy – Phil Hosken on Richard Trevithick and the invention of the high-pressure steam engine (video)

As shared in my previous post (here), the historical road to entropy started with Denis Papin’s development of the piston-in-cylinder assembly and Thomas Newcomen’s and James Watt’s subsequent efforts to commercialize and continuously improve fire engines or atmospheric engines built around this assembly. Steam at atmospheric pressure was employed in these engines, not as aContinue reading “The Road to Entropy – Phil Hosken on Richard Trevithick and the invention of the high-pressure steam engine (video)”
