Episode notes
Work vs. Heat
- Work is directly useful, coordinated energy transfer, like pushing a rock uphill.
- Heat is random, uncoordinated energy, though engines can convert it to work.
Probability, Information, and Thermodynamics
- Statistical mechanics reframed thermodynamics using probability and information.
- Boltzmann's H-function, related to entropy, foreshadowed information theory.
Maxwell's Demon and Landauer's Principle
- Maxwell's demon challenged the second law by using information to create order.
- Landauer showed that erasing information costs work, resolving the paradox.
