Phys.org / Researchers use AI to evaluate a systematic framework to describe molecular order in liquid water

Water is the most abundant liquid on Earth's surface, and it is highly anomalous compared with other liquids because it expands upon freezing. The anomalies in water have been linked to how its microscopic structure changes ...
