golden ratio

The Golden Ratio, also called Divine Proportion, is what artists reckon to be the ratio controlling the dimensions of any beautiful figure and which applies to monuments from the Parthenon and the domes of Persia, to the art of the Renaissance.The pyramid exhibits such a high degree of precision in construction and orientation that it is little wonder ill- founded legends have grown up around it. It is said to be the most accurately aligned structure in existence, facing true North with only 3/ 60th of a degree of error (the misalignment in the telescope's sensor axis of the Paris observatory is 7min of arc, or twice the pyramid's error, while the Meridian Building at Greenwich Observatory in London has an inclination of 9min). Moreover, the pyramid's site was selected so as to allow for astronomical observations. It was determined as a site that would be suitable for a building with 61/2 million tons of stone, whose height was 147m and base area 53000 m . So, whereas Egyptologists adopt the view that the ancient Egyptians built the Great Pyramid as a tomb for Khufu, others suggest that their intention was to build a geodesic monument that would demonstrate their knowledge of the earth's shape and size, or perhaps an astronomical observatory.math
