"This variation on a memento mori skeleton ring features the skeleton on a black ground beneath the central crystal (rather than the usual skull or hair seen in rings of this type). The band is a high-carat gold in a beautiful scrolled design with black enameling, and it memorializes the deceased: “J. Gardiner Ob. 19 May 1764 AE 51.” Two smaller crystals bookend the central crystal."

In mathematics, the notion of permutation relates to the act of permuting, or rearranging, members of a set into a particular sequence or order (unlike combinations, which are selections that disregard order). For example, there are six permutations of the set {1,2,3}, namely (1,2,3), (1,3,2), (2,1,3), (2,3,1), (3,1,2), and (3,2,1). #Education #Permutation #Glogster

NEW TERM - "CLIMATEGATE" Surpassing "Globalwarming" as a Google Search! The new term that is spreading like lightning, “climategate”. For example, a recent search permutation yield this stat: "global warming" – 10,100,000 searches / "climategate" – 10,400,000 searches. Note that these are web searches, not news searches, but Google suggests a few news stories first. These two searches were conducted about 1 minute apart.
