Comets are chance visitors from the icy reaches of the outer Solar

System. In this lecture I describe the properties of comets, their

historical importance, and introduce the "dirty snowball" model of a

comet nucleus. At the end of class I created a model of a comet nucleus

from common household and office materials, unfortunately I could not

arrange for a videographer in time. Recorded 2007 Nov 28 in 1000

McPherson Lab on the Columbus campus of The Ohio State University.
