Nonetheless, 1950 is a long time ago now—should we adjust the starting point to 2000?No, the same problem would have to be addressed again in the coming years.Radiocarbon dating was invented in the late 1940's, and within a few decades, it was discovered that while the dates retrieved from the method have a sound, repeatable progression, they are not a one-to-one match with calendar years.Most importantly, researchers discovered that radiocarbon dates are affected by the amount of carbon in the atmosphere, which has fluctuated greatly in the past for both natural and human-caused reasons (such as the invention of iron smelting, the Industrial Revolution, and the invention of the combustion engine).One advantage to using BP is it avoids the occasionally irate philosophical debate about whether, in this multicultural world of ours, it is more appropriate to use AD and BC, with their explicit references to Christianity, or to use the same calendar but without the explicit references: CE (Common Era) and BCE (Before the Common Era).The problem is, of course, that CE and BCE still use the estimated date of the birth of Christ as the reference points for its numbering system: the two years 1 BCE and 1 CE are numerically equivalent to 1 BC and 1 AD.

Unlike radiocarbon dates, TL dates are calculated in straight calendar years—and the dates measured range from a few years to hundreds of thousands of years.Tree rings, which keep a record of the amount of carbon in the atmosphere when they are created, are used to calibrate or fine-tune radiocarbon dates to their calendar dates.Scholars use the science of dendrochronology, which matches those annular rings to known carbon fluctuations.Scientists have developed a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage.Reporting at the 239th National Meeting of the American Chemical Society (ACS), they said it could allow scientific analysis of hundreds of artifacts that until now were off limits because museums and private collectors did not want the objects damaged.
