INTERDOC_57 — Cascade Pattern Across Civilization Resets

Three civilization-altering events — the Younger Dryas climate reversal (c. 12,800 years ago), the Late Bronze Age Collapse (c. 1177 BCE), and the Justinianic Plague (541–549 CE and centuries of recurrence) — share struc

ZD_1_05 — Computational Complexity: P vs NP and the Limits of Efficient Computation

Computational complexity theory classifies problems not by whether they can be solved, but by how efficiently they can be solved — and its central open question, P vs NP, is one of the seven Clay Millennium Prize Problem
