All that is necessary is for anyone to produce one shred of archival evidence of their having noted pi or pi approximate as a mathematical concept. The Ancient Egyptians were trained in cubits, unit fractions and seked and sadly therein lies the problem. The Ancient Egyptians by the use of unit fractions were unable to express mathematically our values of pi, phi, sqrt2, sqrt3 or sqrt5. If they were unable to express these values in their writings how could they possibly be used in their calculations or designs?
From the ancient archives problem #50 of the Rhind Mathematical Papyrus, we know the Ancient Egyptian used 8/9 diameter squared to find the approximate area of a circle. The written solution says, "subtract 1/9 of of the diameter which leaves 8 khet. The area is 8 multiplied by 8, or 64 setat." Where is there any mention of pi?
There is also problem #10 of the Moscow Mathematical Papyrus calculating the the surface area of a hemisphere by a similar method. "Take 1/9 of 9 (since) the basket is half an egg-shell. You get 1 Calculate the remainder which is 8. Calculate 1/9 of 8. You get 2/3 + 1/6 + 1/18. Find the remainder of this 8 after subtracting 2/3 + 1/6 + 1/18. You get 7 + 1/9. Multiply 7 + 1/9 by 4 + 1/2. You get 32. Behold this is its area. You have found it correctly". Where is there any mention of pi.
Although everyone assumes and wants to believe otherwise neither of these methods made use of pi. There is not one mention of pi or an approximation of pi anywhere in the ancient archives. Logically if there are no notations of pi in the ancient archives it should be evident they did not feel pi important enough to their world of mathematics to be noted.
Our finding pi ratio in a circle doesn't prove a thing since finding pi, an inherent value of any circle, is what we were trained to do. Not true of the Ancient Egyptian Builders. Ten million calculation finding pi does not prove the Ancient Egyptians were aware of pi! One notation from the ancient archives will!
