It is the oldest and only surviving of the Seven Wonders of the World. It is the Great Pyramid of Giza. It needs no speculation regarding appearance, size or shape. It is located in the city of Giza, a necropolis of ancient Memphis, and today is part of Cairo, Egypt. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an Original Essay The Great Pyramid of Giza is believed to have been built over a period of 20 years. First the site was prepared, then the large stone blocks were transported and placed. An outer casing was used to smooth the surface. This outer shell has disappeared over the years. It is not yet known how the blocks were positioned, but there are many theories. One theory involves the construction of a straight or spiral ramp that was raised as construction progressed. The ramp, covered in mud and water, made it easier to move the blocks. The blocks were pushed or pushed into place. Another theory says the blocks may have been placed using long levers with a short, angled foot. Throughout history, the pyramids of Giza have inspired the human imagination. The pyramids were called "Joseph's granaries" and "Pharaoh's mountains". Today, the Great Pyramid is enshrined, along with other pyramids and the Sphinx, in this region of the Giza Plateau. When the Great Pyramid was built it was 481 feet (145.75 m) tall, over the years it has lost about 30 feet (10 m) from the top. It was the tallest structure on Earth for over 43 centuries, it was surpassed in the 19th century AD. It was covered with a casing of stones to smooth the surface. Some of the casings are still visible near the top of Khefre's pyramid. The angle of inclination of the sides is 54 degrees, 54 minutes, 0 seconds. Each side is carefully oriented with one of the cardinal points of the compass (N, E, S, W). The horizontal cross section is square at any level, each side is 229 m (751 ft) long. The maximum error between side lengths is surprisingly less than 0.1%. This structure is made up of approximately 2 million stone blocks, each of the stones weighing more than two tons. It has been said that there are enough blocks in the three pyramids to build a 3 meter high and 0.3 meter thick wall around France. The area covered by the Great Pyramid could contain St. Peter's in Rome, the cathedrals of Florence, Milan, Westminster and St. Paul's in London combined. The entrance to the pyramid is on the north wall. There are many corridors, tunnels and escape shafts which lead to the king's burial chamber or which must have served other purposes. At the heart of the pyramid is the king's chamber. Each of the inner stones fit together so well that a card won't even fit between them. The sarcophagus is also oriented according to compass directions and is only 1 cm smaller than the entrance to the chamber. It may have been introduced as the structure progressed. There are new theories about the origin and purpose of the Pyramids of Giza. The many different theories have to do with astronomical observatories, places of worship, geometric structures built by a long-gone civilization, and theories relating to extraterrestrials. There is little evidence to support extraterrestrial theories. According to most people the pyramids were built by large armies of slaves, by the ancient pharaohs of Egypt to preserve their bodies. They were meant to be monuments to the pharaoh's greatness, filled with treasures for the afterlife. To build such a massive structure, the pharaohs copied the Great Pyramid. The Great Pyramid does not contain the body of the pharaoh, the treasure chamber and nodarling himself. So who built this wonderful structure? The Great Pyramid is thirty times larger than the Empire State Building, its features are so large that they can be seen from the moon. The base covers 13.6 acres, which is equivalent to seven city blocks in midtown Manhattan. Each side of the pyramid has an area greater than five acres. An eight-foot-wide, four-inch-thick highway lane could be built from San Francisco to New York and inserted inside the Great Pyramid. Only a solid stone mountain could support the enormous weight of the Pyramid, and coincidentally there is a solid flat granite mountain. mountain just below the surface of the ground directly below the pyramid. The pyramid is located at the exact center of the Earth's land mass. This means that its east-west axis corresponds to the longest terrestrial parallel that crosses the Earth, passing through Africa, Asia and America. Likewise, the longest terrestrial meridian on Earth, which passes through Asia, Africa, Europe and Antarctica, also passes through the pyramid. Considering that there is enough space on Earth to have 3 billion pyramids, the odds of it being built where it is are 1 in 3 billion. Like our bridge designs, Pyramid pillars have spheres and sockets embedded within them. Being several football fields long, the pyramid is subject to expansion and contraction due to heat and cold, as well as earthquakes, settling and other similar events. After 4,600 years its structure would have been somewhat damaged without such construction. The 144,000 stones of the casing were so radiant that they could be seen from the mountains of Israel, hundreds of miles away. On sunny mornings and late afternoons, the sunlight reflected from this immense 5-acre mirrored surface meant that the pyramid was visible from the moon. In biblical prophecy 144,000 is the number of people (12,000 for each of the 12 tribes of Israel) who are expected to evangelize the world at the end of time. Amazingly, the outer surface stones are cut within 0.01 inch perfectly straight and almost perfect right angles for all six sides. They were placed together with an expected gap between them of 0.02 inches. Modern technology cannot place 20-ton stones with better precision than those in the pyramid. The 0.02 inch gap was designed to allow room for the glue to seal and hold the stones together. The white cement that connected the stones of the casing and made them waterproof is still intact and more powerful than the blocks it unites. Over the centuries, scientists have made many measurements in an attempt to discover more about the mysteries of the pyramid. Among those intrigued was the great scientist and mathematician Sir Isaac Newton. He was trying to work out his famous law of gravity, he needed to know the diameter of the Earth. In the 1600s, no measurement was precise enough, especially since Newton theorized that the Earth's rotation would cause an equatorial bulge. Having heard the legends that the knowledge of the Earth (past and future) was in the pyramid, Newton began the search. After examining detailed measurements made by researchers before him, Newton identified that several key measurements would be in round numbers if the standard unit of measurement was just 0.001 inch larger than the British inch, which is the Jewish sacred inch. The sacred Hebrew inch, 1/25 of a cubit, equals 1.00106 British inches. This discovery made it possible to reveal the secrets of the pyramid and reveal unmistakable mathematical relationships. "For example, we know from geometry that there is a universal relationship between the diameter of.
