We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].
In Nyerup's time, archaeologists could date the past only by using recorded histories, which in Europe were based mainly on the Egyptian calendar.Welcome to the K12 section of the Radiocarbon WEBinfo site.The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.I have tried here to answer some of the frequently asked questions that I receive from students via email, as well as providing some basic information about scientific dating methods."Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.
Libby of the University of Chicago after the end of World War 2.
Libby later received the Nobel Prize in Chemistry in 1960 for the radiocarbon discovery.
They used pottery and other materials in sites to date 'relatively'.
They thought that sites which had the same kinds of pots and tools would be the same age.
The relative dating method worked very well, but only in sites which were had a connection to the relative scale. When radiocarbon dating was developed, it revolutionised archaeology, because it enabled them to more confidently date the past, and to build a more accurate picture of the human past.
The archaeologist Colin Renfrew (1973) called it the development of this dating method 'the radiocarbon revolution' in describing its great impact upon the human sciences.
