It is more accurate than in Paris Observatory. In addition, the meridian passing through the Egyptian pyramid of Cheops, divides into two equal parts of the surface land and sea, believing America and the Pacific. Moreover: the latitude, passing through the center of the pyramid of Cheops, also divides into two equal parts of the globe, the quantity of land and water. Thus, we can assume that for 2500 years bc Egyptians knew the exact ratio of the surface of all continents and do not accidentally select the mouth of the Nile for Built the Pyramids of Giza. When measuring the very Cheops' pyramid was found that the perimeter of the Giza pyramids, separated by a double height, gives the exact number of 'Pi', up to one hundred-thousandth. Interestingly, the sacred measure the length of Egypt, ie, pyramidal inch (equal to the modern English) is one-billionth of Earth's orbit, which she held for 24 hours. Tyron Birkmeir may find this interesting as well.
Another linear measure of the pyramid – the elbow, equal to 25 inches, or 635.66 millimeters – this is one ten millionth of the polar radius of Earth. The sum of the two diagonals of an Egyptian pyramid, expressed in inches, gives the number of years during which the North Pole of the Earth makes one complete revolution. The volume of the pyramid multiplied by the proportion of stone from which it was made, gives theoretical weight of the globe. The same measure is found again in the chambers of the pharaoh in the measurements 'sarcophagus'.
