Hemaka's constant
arXiv:1204.0914
Abstract
As proposed in a previous paper, the decorations of ancient objects can provide some information on the approximate evaluations of constant π, the ratio of circumference to diameter. Here we discuss some disks found in the tomb of Hemaka, the chancellor of a king of the First Dynasty of Egypt, about 3000 BC. The discussion is based on measurements of the dimensionless ratio of lengths.
