INTERDOC_04 — Catastrophe-Migration-Civilization Cycle

The archaeological and paleoclimatic record reveals at least five major catastrophe-migration cycles in the last ~75,000 years, each following a recognizable pattern: a sudden environmental shock (volcanic eruption, cosm

INTERDOC_64 — Cross-Cultural Constellations: Independent Invention vs. Diffusion as a Knowledge-Transmission Probe

The 88 modern IAU constellations are a cultural product — 48 from Ptolemy (~150 CE, derived from Mesopotamian/Babylonian sources), 12 from Keyser and de Houtman (~1596, Dutch East Indies), and 28 filled in by 17th–18th c

ZD_2_15 — Transformer Architecture: Self-Attention and the Foundation of Modern AI

The transformer is a neural network architecture introduced in 2017 that replaced recurrent and convolutional models as the dominant paradigm in artificial intelligence. Its core innovation — the self-attention mechanism

ZD_2_12 — Generative AI: Large Language Models, Diffusion, and the Transformer Revolution

Generative AI refers to artificial intelligence systems capable of creating new content — text, images, audio, video, code, 3D models — that is novel, coherent, and often indistinguishable from human-created work. The fi
