ZH_3_14 — Nighttime Navigation Without Instruments: Stars, Moon, and Memory

For most of human history, navigators crossing deserts, oceans, and arctic wastes found their way using the stars, the Moon, the Sun's position, and memory — without magnetic compasses, chronometers, or sextants. Non-ins

ZH_5_10 — Naked-Eye Observational Limits: Precision, Techniques, and Ancient Achievement

For all but the last ~400 years of human history, every astronomical observation was made with the unaided eye. Understanding the limits and capabilities of naked-eye observation is therefore essential for evaluating anc
