The earliest experiments in radiocarbon dating were done on ancient material from Egypt. Libby’s team obtained acacia wood from the 3rd Dynasty Step Pyramid of Djoser to test a hypothesis they had developed.Libby reasoned that since the half-life of C years, the Djoser sample’s C14 concentration should be about 50% of the concentration found in living wood (for further details, see Arnold and Libby, 1949). Subsequent work with radiocarbon testing raised questions about the fluctuation of atmospheric C14 over time.It was he who helped Isis work the ritual to bring Osiris back from the dead, and who drove the magical poison of Set from her son, Horus with the power of his magic.
Stadelmann suggested that the shafts allowed the king's soul to travel to the "stars that never die" (the circumpolar stars in the northern sky) and the "land of light" (the southern sky).
This argument has a certain simplicity, and seems quite reasonable.
The numbers of C14 atoms and non-radioactive carbon atoms remain approximately the same over time during the organism’s life.
Pi is the relationship between the lunar and solar cycle from the earthly perspective.
No similar shafts were found in other pyramids, but symbolic doors were often used (making the construction of physical doors rather unnecessary).
