I really enjoyed the article, brilliant!
I was interested to see in this discussion that there is still a question mark over the use of the metre in Ancient Egypt. What do you make of the fact that, at the Giza pyramid complex, the geometry that defines the space between and the size of the pyramids combines a rectangle with the number of days in 12 lunar months and phi expressed in metres, a square which contains in metres the number of days in an eclipse or draconic year, and a rectangle which combines phi with the number 741, in metres, 741 being linked to the solar year and 12 lunations like this: 365.242199 x 2 - (365.242199 - 354.62) = 741.126597
The first of these rectangles goes through the apexes of all the first and second pyramids and the meridian that marks the apex of the third pyramid. The second rectangle fixes the position of the second pyramid in relation to the other two, as it passes through the third pyramid and runs along the side of the first rectangle which fixes the centres of the Great Pyramid and the third pyramid. The square fixes the size of the Great Pyramid and second pyramid, as it goes through the south western corner of each of them. All this is expressed in metres.
