tesla_turbine_from_ledger
plain-language theorem explainer
The declaration defines the Tesla turbine structure from the ledger as identical to the energy storage density property from the ledger. Engineers modeling bladeless turbines within Recognition Science would cite it to connect geometry to storage metrics. The definition is a direct alias requiring no lemmas or tactics.
Claim. Let $T$ be the proposition that the Tesla turbine structure satisfies the ledger condition. Then $T$ holds precisely when the energy storage density condition from the ledger holds.
background
This definition sits in the Engineering.TeslaTurbineStructure module, which imports Mathlib and the EnergyStorageDensityStructure module. It supplies an abbreviation that equates the turbine ledger property to the storage density ledger property. No upstream lemmas are required; the definition stands alone as a naming device for downstream use.
proof idea
This is a one-line definition that directly sets the Tesla turbine from ledger equal to the energy storage density from ledger. No tactics, reductions, or lemmas are invoked.
why it matters
The definition feeds the two immediate theorems in the same module: one showing the turbine structure holds via the storage density structure, and one showing the turbine implies the storage density input. It supplies the engineering link that lets Recognition Science constants (phi-ladder, eight-tick octave) reach concrete turbine designs without additional hypotheses.
