David Hatcher Childress, popular Lost Cities author and star of the History Channel’s long-running show Ancient Aliens, takes us to the mysterious ruins in the mountains of Peru and Bolivia in search of ancient technology and the secrets of megalith building. In his new book, packed with photos and diagrams, Childress examines the amazing stonecutting at Puma Punku, a site neighboring the ancient ruins of Tiwanaku near Lake Titicaca in Bolivia. He looks at whether the so-called “Inca walls”-found in Cuzco and at other sites such as Sacsayhuaman, Ollantaytambo and Machu Picchu-were really made by the Incas. The evidence seems to support the idea that they were actually constructed by a far older culture. Childress examines the megalithic construction and underground chambers of Chavin in the Cordillera Blanca of Peru, possibly the oldest megalithic site in South America. He also speculates on the existence of a sunken city in Lake Titicaca and reveals new evidence that the Sumerians may have arrived in South America over 4,000 years ago. Childress demonstrates that the use of “keystone cuts” with metal clamps poured into them to secure megalithic construction was an advanced technology used all over the world, from the Andes to Egypt, Greece and Southeast Asia. He maintains that only power tools could have made the intricate articulation and drill holes found in extremely hard granite and basalt blocks in Bolivia and Peru, and that the megalith builders had to have had advanced methods for moving and stacking gigantic blocks of stone, some weighing over 100 tons. The incredible high-tech world of South America is illuminated in the informative and breezy style for which Childress has always been known. Chapters in the book include: The Lost World of South America; The Enigma of Ancient Technology; Ancient Technology at Tiwanaku and Puma Punku; The Sumerian Mining Complex at Tiwanaku; Mysteries of Lake Titicaca and the Towers; Ancient Technology in Cuzco; The Megaliths of Ollantaytambo; Did the Incas Build Machu Picchu?; and more!

The Olmec language and Teotihuacan language are still outside this preliminary classification: the ones represented by the Olmec area and those of Teotihuacan, which are currently being studied and discovered. Though it is still difficult to prove, there is some probability that the Olmec language preceded Totonac. In contrast, it is more specific than the writings and speech of Teotihuacan, which led to Nahua's development. The Mexican population that migrated to Nicaragua later spread this language in its various variants throughout the central Valley of Mexico, even reaching the south of Mesoamerica, to Nicaragua. During the destruction and abandonment of Teotihuacan around 600, the written system of their successors, the Toltecs, was lost but may have been revived later in Aztec ideographic writing.

Science in Latin America has roots that reach back to the information gathering and recording practices of the Maya, Aztec, and Inca civilizations. Spanish and Portuguese conquerors and colonists introduced European scientific practices to the continent, where they hybridized with local traditions to form the beginnings of a truly Latin American science. As countries achieved their independence in the nineteenth century, they turned to science as a vehicle for modernizing education and forwarding "progress." In the twentieth century, science and technology became as omnipresent in Latin America as in the United States and Europe. Yet despite a history that stretches across five centuries, science in Latin America has traditionally been viewed as derivative of and peripheral to Euro-American science. To correct that mistaken view, this book provides the first comprehensive overview of the history of science in Latin America from the sixteenth century to the present. Eleven leading Latin American historians assess the part that science played in Latin American society during the colonial, independence, national, and modern eras, investigating science's role in such areas as natural history, medicine and public health, the eighteenth-century Enlightenment, politics and nation-building, educational reform, and contemporary academic research. The comparative approach of the essays creates a continent-spanning picture of Latin American science that clearly establishes its autonomous history and its right to be studied within a Latin American context.

A detailed look into ancient advanced technology, science, and medicine--some of which has yet to be reproduced today • Explores countless examples of ancient high tech, including robotics, artificial intelligence, aircraft, solar-powered cannons, high-speed drills, illuminated underground temples, massive refrigerators, and subterranean cities • Examines evidence of advanced medicine in ancient times • Includes examples from ancient Egypt, China, Greece, Babylon, Siberia, the Americas, and India The first self-igniting match was invented in 1805 by Jean Chancel, a French chemist. Yet, in Babylon, 3,600 years before, identical sulfur matches were in common use. On the Panchavarnaswamy Temple in India, built millennia ago, there is a detailed carving of a man on a bicycle, yet the bicycle wasn’t invented in the modern world until 1817. These inventions are only two examples of technology lost in the Dark Ages. Exploring the sophisticated tech achieved by ancient civilizations hundreds and thousands of years ago, Frank Joseph examines evidence of robotics and other forms of artificial intelligence; manned flight, such as hot-air balloons and gliders; and military science, including flamethrowers, biological warfare, poison gas, and solar-powered cannons. He reveals how ancient construction engineers excavated subterranean cities, turned stone walls into glass, lifted 100-ton blocks of granite, illuminated underground temples and pyramids, and stored their food in massive refrigerators. Examples explored in the book include the first known alarm clock, invented by Plato in 4th-century-BC Greece; 600-year-old Aztec whistles that reproduce animal sounds and human voices with uncanny accuracy; Stone Age jewelry from Siberia worked by a high-speed drill; sex robots in ancient Troy, Greece, and China; ancient Egyptian aircraft; and India’s iron pillar exposed to sixteen hundred years of monsoons but still standing rust-free. The author also explores evidence of advanced medicine in ancient times, particularly in Egypt and China, from brain surgery, optometry, and prosthetics to dentistry, magnet therapy, and cancer cures. By examining the achievements of our ancient ancestors, we can not only reverse-engineer their inventions but also learn from their civilizations’ mistakes, enabling us to avoid more dark ages. Imagine how scientifically advanced humanity would be if our early achievements had escaped destruction and been allowed to develop?

Mayan ideas spread via broadcast and influenced divergent cultures and languages. It is possible to trace the influence of the Mayan civilization far beyond its confines (400 to 600 A.D.). One or two of these lesser civilizations may have existed contemporaneously with the great Mayan civilization, but most were at their best long after the great culture had declined. This chapter will emphasize the ties between these lesser civilizations and the Mayas and analyze their characteristics. Toward Mexico and the Isthmus of Panama, we will proceed northwest. Along the Gulf of Mexico and across the Isthmus of Tehuantepec, the Mayas developed their arts of life in narrowing bands. In terms of importance, Comalcalco appears to be the most westerly Mayan city. A large ruin is also located near San Andres Tuxtla, and the Tuxtla Statuette is among the earliest dated Maya objects. Archaic and Maya figurines coexist in this coastal belt, where arid and humid conditions coexist. Mayan culture may have originated here. Little has been studied on the archaeology of this part of Mexico. Although the earliest known rubber specimens were found at Chichen Itza's Sacred Cenote, the material's ceremonial and practical uses are primarily related to the Olmeca and Totonac cultures. In southern Vera Cruz and western Tabasco, where the Aztecs later called Nonoalco, the Olmeca may be found. Ancient Mexican traditions frequently mention this region as a symbol of Maya civilization. Incense, water-proofing, drumstick tips, etc., were all made from rubber. There was also a sacred game played with a large rubber ball, with goals set high in parallel walls of a specially constructed court, which could be compared to basketball. Olmeca may have been a Mayan tribe, but they may also have spoken Mexican. The Olmeca ruled parts of the Mexican highlands before the Toltecs, according to Ixtlilxochitl's history. When the Toltec empire collapsed, they may have fled south, for we find a group of this name in Nicaragua at the time of the Conquest.

Ancient Peru and Bolivia, like Egypt, contain enigmas and mysteries, especially in stone which most conventional scholarship can`t explain. Rather than simply being the exclusively the works of cultures such as the Inca, there are many megalithic wonders which defy both the conventional time lines and known levels of technology attributed to the ancient people of South America. The most glaring example is most likely Puma Punku, near the shore of Lake Titicaca in Bolivia, which hints at not only being several thousand years old, but also seems to have been achieved using what we would call high level machine technology. There are also many sites in Peru, and especially near the city of Cusco that also show the hall marks of having been made by cultures using technology supposedly not known by cultures such as the Inca. A massive collection of photographic and and detailed analysis is contained in this book, as well as on site observations by leading engineers.

Today, the word "God" carries a lot of baggage. People conjure up different meanings for it based on their backgrounds and cultures; it often evokes positive and negative emotions. Humanity living in God's awareness on a day-to-day basis is often complicated for people from the Dwapara Yuga. As previously discussed, atheism and science often limit the Kali Yuga conception of God. According to Sri Yukteswar, God is not a venerable personage who resides in an antiseptic corner of the universe. As a result of God's consciousness, which is pure and beyond form and limitations, our consciousness is an inextricable expression of his consciousness. As we become more aware of ourselves, we become part of God's pure consciousness. Humanity has discovered more profound, subtle aspects of its true identity through the yugas. The layers of wrapping that hide the gift inside get removed as we move through the yugas. Most wrappings will be removed in Satya Yuga, revealing the gift underneath as if through a thin layer of tissue. Each individual in Satya Yuga will experience "God the Spirit beyond this visible world" after removing the last layer.

A unique study of the engineering and tools used to create Egyptian monuments • Presents a stone-by-stone analysis of key Egyptian monuments, including the statues of Ramses II and the tunnels of the Serapeum • Reveals that highly refined tools and mega-machines were used in ancient Egypt From the pyramids in the north to the temples in the south, ancient artisans left their marks all over Egypt, unique marks that reveal craftsmanship we would be hard pressed to duplicate today. Drawing together the results of more than 30 years of research and nine field study journeys to Egypt, Christopher Dunn presents a stunning stone-by-stone analysis of key Egyptian monuments, including the statue of Ramses II at Luxor and the fallen crowns that lay at its feet. His modern-day engineering expertise provides a unique view into the sophisticated technology used to create these famous monuments in prehistoric times. Using modern digital photography, computer-aided design software, and metrology instruments, Dunn exposes the extreme precision of these monuments and the type of advanced manufacturing expertise necessary to produce them. His computer analysis of the statues of Ramses II reveals that the left and right sides of the faces are precise mirror images of each other, and his examination of the mysterious underground tunnels of the Serapeum illuminates the finest examples of precision engineering on the planet. Providing never-before-seen evidence in the form of more than 280 photographs, Dunn’s research shows that while absent from the archaeological record, highly refined tools, techniques, and even mega-machines must have been used in ancient Egypt.
