> Well if i could could figure out howto write it as a fractional rate in a couple of days so could the ancient. I have no idea how the greeks and the Pythagoreans wrote out the diagonal of a unitsquare, but i am sure they could find a nice ratio to work with just as i did.

> Could you math guys look at a special old structure hexagon, the archeologs is just like the mathematicians rather clueless. They think it is a couple of century old system sewage plant. But for anyone with a brain one can clearly see that they marked out a sunboat. It does not seem that properly aligned from east to west go figure. It is a rather strange built up pentagon isn't it but it is not driven by irrationality on the contrary it is built from a very high rational point of view. The ancient priests had very precise mathematical ideas that they encoded in their work.

Call me sloppy popeye i think its a hexagon
