<p>Although humans have touched or used "glass" daily since ancient egyptian times, we have yet to achieve a detailed understanding of its atomistic structure. Glass, like all amorphous material, lacks the periodic long-range order that characterizes crystals (in which the atoms occupy the positions of a regular lattice). However, chemical-bonding constraints enforce the rather high degree of short-range order that is already present in glass during its high-temperature fluid state?the state from which glass is eventually produced via cooling. Although we have some knowledge as to what each atom's immediate surrounding typically looks like in glass, the degree of order on intermediate length scales (the medium-range order) has been controversial for decades.</p>
