$How an Earth-Curvature Calculator Works This video derives the geometry behind an Earth-curvature calculator instead of treating it as a black box. Using the Pythagorean theorem, observer height, target distance, Earth’s radius, hidden height, and an effective-radius correction for atmospheric refraction, the calculations reproduce the calculator’s predicted horizon and visibility values.$
