Egyptian science and engineering in building the Great Pyramid
1 - The mass of one stone in the pyramid weighs between 2 tons and 15 tons.
2 - The number of pyramid stones is about 2.3 million stone blocks.
3 - The weight of the granite stone in the ceiling of the King’s Chamber
70 tons, and no one knows how the ancient Egyptians lifted it, despite its enormous size and weight.
4 - The height of the pyramid is 149.4 meters, and the distance between the Earth and the sun is 149.4 mm One kilometer (one of Egypt's mysterious secrets).
5 - The entrance corridor to the pyramid points to the North Star, and the inner vestibule points to the Sirius star.
6 - The circumference of the pyramid divided by the height of the pyramid equals 2 * 3.14. This number 3.14 in mathematics is called the mathematical constant (t).
7 - Some historians indicate that the pyramid was radiating light at night because it was coated with a radioactive substance.
8 - The position of the three pyramids is parallel to the position of three stars in the sky called Orion’s belt
9 - In the pyramid’s rooms and corridors, it was observed that the electronic, electrical, and mechanical devices stopped working, and the reason is unknown.
10 - “Ham Iono” is the genius Egyptian engineer who built this pyramid. It took 20 years to build and about 100,000 Egyptians worked on it.
11 - The four corners of the pyramid’s base point to the original directions of the Earth (east, west, north, south) with amazing accuracy.
12- The orbit that passes through the pyramids area divides the continents and oceans into two completely equal halves in terms of area.
13- The Great Pyramid is located at the intersection of longitude 30 east and latitude 30 north
14- The ceiling of the King’s Room consists of 7 granite blocks in the form of a truss to relieve the loads on the walls of the room. This is an engineering miracle applied in modern buildings.
15- The width of the coffin inside the King’s Chamber is one inch larger than the width of the entrance to the room, meaning that the coffin was placed before the massive truss roof was made.
16- The mass of the pyramid is on a square surface with a side length of 230.4 metres, meaning that the area of the base of the pyramid is approximately equal to 13 acres, to which is added the outer cladding layer with a thickness of 3 metres.
17- The angle of inclination of the pyramid’s sides is equal, which is 51 * 50’ 40” degrees, fixed and equal in all sides of the pyramid.
