The breakdown of classical nucleation theory at low temperatures for silicate glasses has been a puzzle for decades. Here, Xiaet al. show with a long-term experiment for the specific case of a barium-silicate glass that this anomaly is in fact an artifact arising from insufficient heating time...

angle expands to 50 degrees.“The paper reveals how you would greatly improve the realism, and image depth, and physical simplicity of 3-D display systems, particularly those that don’t require you to wear glasses,” says Gregg Favalora, a principal at the engineering consultancy Optics for ...
The temperature at which the extrapolated entropy of the glass becomes smaller than that of the crystal and therefore an ideal glass transition is hypothesized; originated by Walter Kauzmann in 1948. Extensive Refers to the relation that a quantity scales proportional to the system size. Subextensive...
