What is the purpose of absolute dating
But other timekeeping methods exist and are still used in the modern world, circumventing the easy processing of dates and history between cultures.Throughout history, time has been defined in a variety of ways: by everything from the current ruler, or empire, or not defined at all. Different cultures around the world record time in different fashions.According to the Gregorian calendar, it is the year 2009 AD. The Kaliyuga Hindu Calendar maintains it is 5110, the Islamic calendar 1430 and the Persian, 2630.Dates could be assigned based upon scientific evidence rather than on the inconsistent mathematics, historical comparisons and simulated typologies of artifacts that had previously regulated time.The most well known and oft used form of radiometric dating is radiocarbon dating. It has helped define the ages of man in ways never thought possible and led the way for a vanguard of scientific techniques that have further defined time for humanity and beyond.Chances are, right now, you have a Gregorian calendar stuck to your wall.This calendar, with the months January through December, is a business standard used in many places round the world to define the year: one which hearkens back to Christian and Roman Imperial precedents.
And samples must be collected carefully, as often they have been in stable environments prior to their unearthing by industrious archaeologists and may be easily degraded in the open air or attacked by moisture and sunlight once gathered.The historians of one hundred years ago could only dream of such a wonderful, albeit frightening atomic clock ticking away, helping to mark the passing of the years and the ages of man. No scientific technique is perfect, despite sometimes obsequious media coverage of their capabilities. Among other scholarly scientific suppositions, it assumes that the amount of carbon fourteen in the atmosphere has remained constant bar minor recent fluctuations due to the industrialization of the past few centuries and our impact on the environment.And also, rather importantly, the laws of radioactive decay hypothesize that once a living organism is dead, it no longer interacts with anything in its environment which would affect the speed of its radioactive decay.
But what does it actually do and how much can it tell us?
