F_3_19 — Shared Metallurgical Knowledge: Independent Invention vs. Diffusion
The development of metallurgy — the extraction and working of metals from ores — is one of the most consequential technological achievements in human history, and one of the best arenas for examining the fundamental ques
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

ZH_5_05 — Cross-Cultural Constellation Patterns: Connecting Star Groupings Worldwide
Every documented human culture groups stars into constellations or asterisms — named patterns that organize the sky into a readable, memorizable, and culturally meaningful map. Yet surprisingly few star groupings are uni
