F_1_17 — Austronesian Expansion: From Taiwan to Madagascar and Easter Island
The Austronesian expansion is the largest maritime diaspora in human history, spanning from Taiwan (c. 3500–3000 BCE) across the Pacific and Indian Oceans to ultimately reach Madagascar (c. 500–800 CE) in the west and Ra
F_2_20 — Amber Trade Routes (Baltic to Mediterranean)
Baltic amber (succinite, fossilized resin of Pinus succinifera, 35–55 million years old) was the most extensively traded organic material in European prehistory and antiquity, linking the shores of the North and Baltic S

ZA_2_20 — Dark Matter & Dark Energy
Approximately 95% of the universe's total energy content consists of two components that have never been directly detected: dark matter (~26.4%) and dark energy (~68.7%), with ordinary baryonic matter comprising only ~4.

The quantum internet envisions a global network that distributes quantum entanglement between distant nodes, enabling fundamentally new capabilities: quantum key distribution (QKD) for information-theoretically secure co
ZA_4_24 — Bose-Einstein Condensates
A Bose-Einstein condensate (BEC) is a state of matter in which a dilute gas of bosons is cooled to temperatures near absolute zero (~100 nanokelvin), causing a macroscopic fraction of the particles to occupy the lowest q
