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.
For periods without a historic record, attempts have been made to categorize tool kits, pottery styles, and architectural forms into regional timelines.
These various chronologies and their inherent inconsistencies, known as ‘relative dates,’ are a constant series of hurdles in the quest of historians and archaeologists to record mankind’s existence on earth.
However, in the 1940s, the organization of time was transformed by the revelation of radiometric dating and the subsequent creation of a scientific chronology of humankind, known as ‘absolute dating’.
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.
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.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.But what does it actually do and how much can it tell us?Radiocarbon dating is a side benefit of a naturally occurring scientific process.Living organisms absorb a proportional amount of radioactive carbon fourteen isotopes to what is constantly present in the earth’s atmosphere.
