Why Icicles Are Long And Thin
Mathematical Physics Explains How Icicles Grow

February 1, 2007 — When droplets of melted snow drip down an icicle, they release small amounts of heat as they freeze. Heated air travels upwards and helps slow down the growth of the icicle's top, while the tip is growing rapidly. Knowledge of the mathematical equations that govern icicle growth -- the same that apply to stalactites -- could help in the prevention of icicle formation on power lines.
