I have always found it interesting how a person can relate a real life situation to chemistry. "The Nature of Glass Remains Anything but Clear" by Kenneth Chang explains how glass is actually a liquid even though it appears to be a solid. Peter Harrowell explains, "They're the thickest and gooiest of liquids and the most disordered and structureless of rigid solids." It is not yet totally understood how or why glass is a solid. Understanding glass could help make better eyeglasses and help drug makers make medicines that could be taken orally instead of injected through the bloodstream. Many different theorists have made hypotheses about glass, but no one is quite sure what is correct. However, they know that, "in liquids, molecules jiggle around along random, jumbled paths. When cooled, a liquid either freezes, as water does into ice, or it does not freeze and forms a glass instead." Understanding how glass works can open many doors to the future.
