Glass might look and feel like a perfectly ordered solid, but up close its chaotic arrangement of particles more closely resemble the tumultuous mess of a freefalling liquid frozen in time.
scientists Dimitrios Fraggedakis, Muhammad Hasyim, and Kranthi Mandadapu of the University of California, Berkeley, there is a behavior on the temperature boundary of supercooled liquids and solids where the static particles remain excited, 'twitching' in place.in everyday life: solid, liquid, and gas, or vapor. Each is defined by the relationships between their particles and surrounds.
Just how these seemingly haphazard connections switch from viscous streams of flowing molecules to a static landscape is far from obvious. "Our theory predicts the onset temperature measured in model systems and explains why the behavior of supercooled liquids around that temperature is reminiscent of solids even though their structure is the same as that of the liquid,""The onset temperature for glassy dynamics is like a melting temperature that 'melts' a supercooled liquid into a liquid. This should be relevant for all supercooled liquids or glassy systems.
