lags-of-two-streams

The autocorrelation of each disturbance against lag, over 40,000 draws at a coupling of 0.5. Both are correlated at 8 and 13 — the two contact offsets of a stem at this rise — and at 5, their difference, which is where the second comb comes from. The inherited disturbance, in which an organ takes a share of what its neighbours were displaced by, also carries power at 16, 21, 26, 29, 34: every sum and difference of the two offsets, because an error that enters it is passed on again and again. The shared disturbance, in which an organ takes a share of the fresh deviates drawn for those neighbours, carries nothing past the two. The number on the right is how far each one's block means wander: over 100 organs the inherited stream's block means have 5.5 times a white stream's variance and the shared one's 2.2.

Drawn at its defaults, in a disturbance with no history. It takes no options at all, so every essay calling it gets this exact drawing.

What a plant might be doing

A disturbance that is not passed on

The disturbance that forges every observable on this site does two things at once — it correlates an organ's error with its contact neighbours', and it hands that error on to be handed on again. Every result about it has been unable to say which half did the work. This is the control that takes the second half away and keeps the first.

 What a plant might be doing

The forgery needs a history

A disturbance passed between touching organs manufactures the comb, the second comb and the parastichy pair on an arrangement with no rule in it — which is why the comb stopped being evidence. Give the organs the same correlation with no accumulation in it and the forgery collapses: one seed in eight returns a pair, and the comb is the noise floor.
