Love-hungry teenagers and archaeologists agree: dating is hard.But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.One is the Marcel Richard list of some 900 catalogs that describe 55,000 Greek manuscripts, Biblical and non-Biblical, belonging to 820 libraries or private owners. The general style, handwriting, punctuation, and other features resemble that of the first letter. Minuscule script could be written more rapidly and compactly, which saved both time and parchment.This vast amount of information assists translators and also helps paleographers to date manuscripts more accurately. But much to your delight, the second letter has a date on it. Paleographers have their preferred methods of dating manuscripts.The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.
In the 20th century, additional tools became available to paleographers. Minuscule writing, a small form of book hand, was employed from the 8th or 9th century C. till the middle of the 15th century, when printing by means of movable type began in Europe.
Until this century, relative dating was the only technique for identifying the age of a truly ancient object.
By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.
The absolute dating method first appeared in 1907 with Lord Rutherford and Professor Boltwood at Yale University, but wasn’t accepted until the 1950s.
The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.
