ZA_4_26 — Luminiferous Aether: The Medium That Wasn't, and the Physics It Created

Luminiferous aether — from the Latin lumen (light) and Greek aithēr (upper sky) — was the hypothetical medium through which light was thought to propagate. Just as sound requires air, 19th-century physics held that light

ZA_4_25 — Caloric Theory: The Heat Fluid That Built Thermodynamics

Caloric theory held that heat is a self-repelling, weightless, indestructible fluid — calorique — that flows from hotter bodies to cooler ones and can be stored within matter. Formalized by Antoine-Laurent de Lavoisier i
