The information geometry of black holes and computation.

A precision instrument for the D3 framework — nine exact results connecting Landauer information erasure to black-hole geometry, with live interactive graphs you can probe for hours.

D3(T) = 2G·kB·T·ln2 / c⁴  [m per bit]
R_total = ∫ D3(M)·dN(M) = rs(M₀)  [exact — all constants cancel]
h(χ,q) = 4σ / (2(1+σ)−q²)  [Kerr-Newman master]
