Dragon's Teeth Square pyramids of reinforced concrete first used in Europe during WW2 to impede the movement of tanks and mechanized infantry. If deployed in the thousands they could stall enemy forces for quite some time. Due to the huge numbers laid and their durable construction, many thousands of dragon’s teeth can still be seen today. They range from 3 to 4 feet tall.
Powerful Radioactive Material Found In Pyramids, Ancient City Teotihuacan in Mexico has long baffled archeologists who discovered the presence of Mica, a powerful radioactive insulator, among the ruins of the ancient city. "In 1906, a worker digging at the site made one of the most important and mysterious discoveries that would forever change how we looked at Teotihuacan. On the fifth deck of the Pyramid of the Sun, a worker discovered a thick layer of laminated mica covering a huge area. It was an odd place for the material to be found". "At that time, in 1906, mica was invaluable in the market. It was used for the construction of capacitors and was considered an incredibly well-appreciated electrical and thermal insulator which had a melting point over 1,100 degrees Celsius. For some obscure reason, the architects of Teotihuacan placed it there in the second century BC, at the time of the greatest expansion of their civilization. The question was why"? (Read More)
Secrets Of Mica Chambers Of Teotihuacan "The so-called mica chambers remain one of several unsolved mysteries of Teotihuacan. Mica is highly elastic, heat-resistant up to 1470 degrees F (800 degrees C), and resistant to both sudden temperature changes (heat/cold) and organic acids. It is unclear what purpose these special rooms served". "According to one theory, sensitive materials were stored in these chambers for protection against extreme external heat for example. Other theories suggest the heat was generated inside the chambers and that the rooms may have served as smelting ovens".
"Mica, rowed the boat ashore"...and finally..... Mica, And Why Its Builders Used It In The Construction Of Teotihuacan "In 1906, another surprising discovery was made in Teotihuacan as researchers discovered a thick layer of Mica on top of the Pyramid of the Sun." "The Mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage. Sheet mica is used in electrical components, electronics, isinglass, and atomic force microscopy. Other uses include diaphragms for oxygen-breathing equipment, marker dials for navigation compasses, optical filters, pyrometers, thermal regulators, stove and kerosene heater windows, radiation aperture covers for microwave ovens and mica thermic heater elements. Mica is birefringent and is therefore commonly used to make quarter and half wave plates. Specialized applications for sheet mica are found in aerospace components in air-, Ground-, and sea-launched missile systems, laser devices, medical electronics, and radar systems. Mica is mechanically stable in micrometer-thin sheets which are relatively transparent to radiation (such as alpha particles) while being impervious to most gases". – Wikipedia "Most importantly, researchers have not found Mica in any other archaeological site in the vicinity, or in the Americas. Why there are traces of Mica at the Pyramid of the Sun and other constructions in Teotihuacan is a mystery that archaeology has yet to explain properly. Mysteriously, the type of Mica used in Teotihuacan is believed to have originated in Brazil".
The Nic Cage Pyramid "Actor Nicolas Cage is an eccentric man. Born Nicolas Kim Coppola, nephew of The Godfather director Francis Ford Coppola, Cage adopted his working name to avoid nepotism on the job and claims to have gotten inspiration from Marvel superhero Luke Cage". "Cage’s acting style has been described by many as “operatic.” He is well known for his emotionally theatrical style, which he dubs “Noveau Shamanic.” "As interesting as his acting career is, his personal life is equally enigmatic. His celebrity success has allowed him to buy private islands, dinosaur fossils, English and German castles, shrunken heads, albino cobras, exotic artworks, a supposedly haunted mansion, and a very strange mausoleum in New Orleans".
