I think there is an orthographic and/or grammar and/or spelling error in the page title "Chronology of computation of pi". I think it should read Chronology of computations of pi (or "Chronology of the computation of pi"). I post this comment here with the current date; if someone runs across this page in some months and there has not been any protest, I think we should move it to the new title (creates a redirect, anyway).

(PS: I would even prefer "approximations" instead of "computations", but this goes beyond the correction of a spelling error.) — MFH:Talk 20:08, 16 March 2006 (UTC)

[edit] Egyptian valueof Pi

You have included the value of Problem 50 and ignored the value of problem 48 in your stated value of Pi. The 3x3 grid square of 9 units convereted to an octagon goes hand in hand with the 9 unit diameter circle. This is to give a maximum (3.16) and minimum (3.111') value for Pi. The egyptian are not stating Pi - 3.16 !

[edit] Another Egyptian value of Pi

It might be that the Egyptians had an better approximation of pi than it says now in the article, also at an earlier date. E.g. in the wikipedia article about the "Great Pyramid of Giza" it says the pyramid is thought to be 280cubits high with 440cubits long basesides (cubits stands for Royal Cubit, a standard egyptian length used in those days).

It makes the ratio between height and sum of the 4 baseside-lengths of this pyramid as 2 pi (1760 diveded by 280). This all might mean that the egyptians had an about two times more accurate number for pi with 22/7 in about 2500 BC (the generally accepted estimated date of completion of the Great Pyramid as stated in the same article about the pyramid). 83.83.104.161 (talk) 08:42, 28 January 2008 (UTC)sonty567
