Racemization dating method

Seriation is thought to be the first application of statistics in archaeology. The most famous seriation study was probably Deetz and Dethlefsen's study Death's Head, Cherub, Urn and Willow, on changing styles on gravestones in New England cemeteries.The method is still a standard for cemetery studies.Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site.Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating.For example, JJA Worsaae used this law to prove the Three Age System.Seriation, on the other hand, was a stroke of genius.For example, since each Roman emperor had his own face stamped on coins during his realm, and dates for emperor's realms are known from historical records, the date a coin was minted may be discerned by identifying the emperor depicted.Many of the first efforts of archaeology grew out of historical documents--for example, Schliemann looked for Homer's Troy, and Layard went after the Biblical Ninevah--and within the context of a particular site, an object clearly associated with the site and stamped with a date or other identifying clue was perfectly useful. Outside of the context of a single site or society, a coin's date is useless.

    “To focus so much on the behavior and using that to define somebody’s relationship with God is legalism,” Kim said. Another Christian friend of mine, Jane, recently flashed me her chastity ring, but told me she’s willing to do “other bedroom activities” that don’t involve going “all the way.” To her, there’s nothing wrong with testing the waters with a serious boyfriend before they get married.
