F_1_01 — Trans-Oceanic Contact

Mainstream history asserts that the Americas were isolated from the Old World from ~11,000 BCE until Columbus (1492 CE), with the exception of brief Norse contact (~1000 CE). However, chemical evidence (cocaine and nicot

F_1_26 — Pre-Columbian Chicken DNA & Trans-Pacific Contact

The question of whether chickens (Gallus gallus domesticus) were present in South America before the arrival of Europeans in 1492 is a seemingly mundane zoological problem with profound implications for the history of pr

ZA_3_04 — Antimatter: CP Violation and the Matter-Antimatter Asymmetry

For every fundamental particle there exists an antiparticle with identical mass but opposite charge. When matter and antimatter meet, they annihilate into pure energy. Dirac's 1928 equation predicted antimatter's existen

Topology — the study of properties preserved under continuous deformation (stretching, bending, but not tearing or gluing) — originated with Euler's solution to the Königsberg bridge problem (1736) and evolved into one o
