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?

A “brilliant and practical” study of why our brains aren’t built for media multitasking—and how we can learn to live with technology in a more balanced way (Jack Kornfield, author of The Wise Heart) Most of us will freely admit that we are obsessed with our devices. We pride ourselves on our ability to multitask—read work email, reply to a text, check Facebook, watch a video clip. Talk on the phone, send a text, drive a car. Enjoy family dinner with a glowing smartphone next to our plates. We can do it all, 24/7! Never mind the errors in the email, the near-miss on the road, and the unheard conversation at the table. In The Distracted Mind, Adam Gazzaley and Larry Rosen—a neuroscientist and a psychologist—explain why our brains aren't built for multitasking, and suggest better ways to live in a high-tech world without giving up our modern technology. The authors explain that our brains are limited in their ability to pay attention. We don't really multitask but rather switch rapidly between tasks. Distractions and interruptions, often technology-related—referred to by the authors as “interference”—collide with our goal-setting abilities. We want to finish this paper/spreadsheet/sentence, but our phone signals an incoming message and we drop everything. Even without an alert, we decide that we “must” check in on social media immediately. Gazzaley and Rosen offer practical strategies, backed by science, to fight distraction. We can change our brains with meditation, video games, and physical exercise; we can change our behavior by planning our accessibility and recognizing our anxiety about being out of touch even briefly. They don't suggest that we give up our devices, but that we use them in a more balanced way.

The book provides a broad, multidisciplinary platform to learn more about the properties of nanoporous gold from an interdisciplinary perspective from an overview of state-of-the-art applications and techniques to the latest research progress.

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.

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!
