Well, PI is involved in a circle. And this is sounding like circular reasoning to me.
Nosy,
This recalls to me a t.v. show I watched on the pyramids maybe 10 years ago. back when I had a t.v. It might have been on the Discovery channel. I really don't remember. I do recall that the archeologists addressed this pi thing with a solution that made some sense though I don't recall the detail. I think they were showing that pi could show up in the measurements of the pyramid even though the egyptians didn't know what pi was.
What they did was demonstrate the use of a wheel with a marked rim to roll along and measure out length for the sides of the base. Well, using a wheel would tend to as an artifact introduce a pi factor into the measurements.
Does anyone here recall this show, or better something published by pyramid buffs, those interested in reconstructing how the pyraminds were built?
peace,
