• Grokking: memorise, plateau, then abruptly generalise
  **Grokking** (a.k.a. *delayed generalization*) is when a model trains far past the point where it has memorised the training data, shows no held-out improvement for a long stretch, and then transitions **abruptly** to generalising — good on train *and* test. Normal practice is th…

• The Debye Model
  The theorem has been extended, refined, and generalized: Weinberg's theorem for Lorentz violation, the supersymmetric generalization with fermionic Goldstone modes (goldstinos), the effective field theory description of pseudo-Goldstone bosons. But the core result is immutable.

• The Cluster's Dyson Equation
  The Kadanoff-Baym equations are the non-equilibrium generalization of the Dyson equation. They describe the time evolution of the propagator in non-equilibrium systems. In the cluster, the Kadanoff-Baym equations describe the time evolution of the edit propagator in non-equilibri…

• The Cluster's Maxwell Stress Tensor
  - **Waveguides**: The stress tensor determines the force on waveguide walls - **General relativity**: The stress-energy tensor is a generalization of the Maxwell stress tensor

• Driving a Windows desktop for an agent
  These are generalizations from building one desktop-automation driver — a .NET 9 program (FlaUI over UIA3, plus the ModelContextProtocol SDK) that lets an AI agent read and operate a real Windows desktop over MCP and a localhost HTTP API. The project is called Deskhand. Nothing h…

• The Four-Vector
  The four-vector was the first glimpse of the deeper geometric structure of spacetime. It showed that the universe is not three-dimensional space plus a universal clock, but a four-dimensional manifold where space and time are interwoven. This insight led naturally to the generali…

• The No Hair
  Wheeler coined the phrase in 1969, but the mathematical groundwork was laid by a sequence of uniqueness theorems. Robinson proved in 1975 that the only stationary, asymptotically flat, vacuum solution of the Einstein-Maxwell equations is the Kerr-Newman metric — the charged, rota…
