What is “Deep Simplification”
“Un-deep” & “deep” examples: Range & Metric equations, resp.
Deep Simplifications from Jaynes’‘57 PR?
A Zeroth Law from Gambling Theory...
Applies for any shared & conserved quantity, not just energy!
Gives “physical” units for temperature (e.g. Troom = 1/40 eV/nat).
Yields equipartition, ideal gas law, mass-action almost trivially.
Further Inference Based on Incomplete Information...
Opens door to information engines, & systems far from equilibrium.
These include the engines of life, macroscopic and microscopic.
Yields complementary roles in evolution for excitations and codes.
