S_4_06 — Interstellar Communication — SETI, Breakthrough Listen, and the Search for Intelligence
The scientific search for extraterrestrial intelligence (SETI) has proceeded for over six decades since Frank Drake's Project Ozma (1960) first aimed a radio telescope at nearby stars, yet no confirmed signal of intellig
S_1_06 — Internet and Digital Civilization — From ARPANET to the Algorithmic Age
The internet — humanity's most transformative communication infrastructure — evolved from a U.S. military research network (ARPANET, 1969) through academic adoption, commercialization (1990s), and the World Wide Web (Ber
F_1_09 — Austronesian Expansion: The Greatest Maritime Migration
The Austronesian expansion is the most extensive pre-modern maritime migration in human history, covering over half the globe — from Taiwan to Madagascar, Easter Island, Hawaii, and New Zealand — over approximately 5,000
