Story summary
- The Mpemba Effect (ME) posits that hotter water can freeze faster than colder water under specific conditions.
- This phenomenon has been studied since Aristotle but lacks a definitive explanation.
- Recent models, including TIP4P/Ice and Lennard-Jones, demonstrate ME can occur without metastability, influenced by critical fluctuations.
- Findings reveal that different models produce varying results on ice formation and nucleation barriers.
