  • Researchers from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) used supercomputers to simulate ice formation and confirm the Mpemba Effect.
  • The Mpemba Effect is a phenomenon where hot water can freeze faster than cold water under certain conditions.
  • Aristotle mentioned this effect in his book Meteorologica.
  • Tanzanian student Erasto Mpemba brought attention to this phenomenon in 1969.
