The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
Erasto Bartholomeo Mpemba [1] (1950–2023) [note 1] was a Tanzanian game warden who, as a schoolboy, discovered the eponymously named Mpemba effect, a paradoxical phenomenon in which hot water freezes faster than cold water under certain conditions; this effect had been observed previously by Aristotle, Francis Bacon, and René Descartes.

David Auerbach, Supercooling and the Mpemba effect: when hot water freezes quicker than cold, American Journal of Physics, 63(10), 1995. Words like superficial and looks do not indicate hard core physics, and this comes from the source supposedly proving Mpemba? Wrong, try again. Hard Raspy Sci 09:54, 5 November 2005 (UTC)
