> For a number of reasons the study of viscous liquids approaching the glass transition is likely to remain an
> exciting branch of condensed-matter physics for years to come: 
> 
 1 the most basic problems are unsolved; 
> 
 2 computers are still too slow for the secrets of viscous liquid dynamics to be revealed by brute force simulations; and
> 
 3 there is a **small, dimensionless number characterizing viscous liquids just above the glass transition** $10^{−30}$, indicating that a simple and general theory for viscous liquid dynamics may exist. 

> Although the research field is still open to new theoretical developments and even simple phenomenological modeling, **future breakthroughs are likely to come from careful and accurate experiments.**

> ... but to survive undamped to temperatures well above T, in strong glass-formers [lOl,lOZ]. The localization of low frequency modes [103,104] which is thought to be associated with boson peak damping [105] may thus be the key phenomenon triggering the glass transition.

> ....the glass transition is in a state of rapid development. Highlights are the advent of microheterogeneity models which go far to rationalize
> fragility, and **the correlation of boson peak physics with glass transition**. The random energy model deserves more attention.
