Essays and working notes. Each stands on its own. The framework several of them lean on fits on one page — the sheet.
Recovery Timenear a tipping point, a system recovers more slowly from small knocks — recovery time, variance, and autocorrelation all rise (Scheffer 2009; applied to mood, van de Leemput 2014). an early-warning signal, real and imperfect: a thing to notice by, not a prediction. a proposal.
Entropy Is in the Description"entropy may not exist" — true at the fundamental level (entropy is coarse-graining-relative, Jaynes; fine-grained entropy is constant, Liouville; the arrow is in the start, Loschmidt) and false at the practical (it is real, lawful, the second law holds). a number your description assigns, not a substance. a proposal.
