The C14 method has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.
All plants and animals on Earth are made principally of carbon.
Eventually, a particle is emitted from the carbon 14 atom, and carbon 14 disappears.
Libby found that it took 5568 years for half the radiocarbon to decay.
Because carbon is very common on Earth, there are alot of different types of material which can be dated by scientists.
Below is a list of the different kinds of materials which can be dated: Libby tested the new radiocarbon method on carbon samples from prehistoric Egypt whose age was known.
Rasmus Nyerup's quote reminds us of the tremendous scientific advances which have taken place in the 20th century.
In Nyerup's time, archaeologists could date the past only by using recorded histories, which in Europe were based mainly on the Egyptian calendar.
Libby later received the Nobel Prize in Chemistry in 1960 for the radiocarbon discovery.
