What is the title 82KY about?

82KY is derived from 82,000 years, that is the scientifically determined age of the oldest known human artifacts that are probably served as personal adornment, jewelry that is! Read more about it in PNAS! Since the purity of gold items are marked as karat , 24K being fine gold (24 parts of gold in 24 parts of metal) and the color is often noted as in 14KY(ellow), one can read the title as fine (yellow ) gold ( 82 parts gold in 82 parts metal). The division of metals into 24 parts for this purpose is totally arbitrary and reflects the earlier widespread use of of the base-12 number system (see dozen, inches, etc.)
