PhysicsLogic / Lorenz 1963

Determinism and Forecast Accuracy

Follow an information-limited prediction obstruction through the paradigm, metric framework, and an actual flow.

Definitions and assumptions

Scope and physical limitations

The main example is the unstable linear mode dx/dt = x, not Lorenz's bounded nonperiodic flow or an atmospheric forecast horizon. The discontinuous threshold iterate is a separate definition diagnostic. Accuracy feasibility does not assert an algorithm, computational efficiency, or error probability.

Compare their definitions and hypotheses. Shared declarations may be instantiated differently; differences do not establish equivalence or implication.

No comparison argument selected.

Compare an earlier extraction

Compare the displayed specifications with an earlier JSON export. This compares text, not mathematical equivalence. Files stay in this browser.
