Hermione,
Forgive me. I will belabor this thread no more beyond this post, however I do believe you are misreading what I have said, and in fact are taking the opposite meaning from my statements.
You state, "The theory that the AE knew about pi has been aired on Ma'at on countless occasions", and that you are weary of this subject.
I have been as clear as I have been able to be that I am not talking about an Egyptian understanding of Pi. Rather, I am talking about their fascination with squaring the circle both for area and circumference. This is not the same thing, although in modern parlance it is assumed to be. If you are ever so moved, you can read my varied and previous posts, my website, or contact me directly for further discussion.
I do not mean to weary you or others, but it is precisely this distinction which lies at the heart of the matter. The distinction is there, and indeed, it requires that one not think in modern terms. Think 11 to 14 for a circle squared for circumference (side of square to circle's diameter), and 8 to 9 for a circle squared for area (side of square to circle's diameter). The interior designs of at least four Old Kingdom pyramids give all appearance of flowing from these two understandings. The Pi relationship need never be mentioned, nor even be recognized. I reiterate that this is an issue that is more than just semantics, and obviously carries with it rather widespread implications.
Best,
Lee Cooper
