Book Description
This book presents the study on Ancient Geopolymers in South America and Easter Island regions, exploring the artificial nature of the volcanic rocks used in the construction of Easter Island's statues. Contrary to the belief that the statues were carved and transported, Davidovits suggests they were made on-site using geopolymer technology. He proposes that this knowledge came from Amerindians from the Andes, specifically the Tiahuanaco region near Lake Titicaca. The book is divided into two parts: the first examines geopolymeric artificial stone technologies in the Andes, and the second establishes a connection between these technologies and Easter Island, 3,700 km away. Davidovits' research includes geological expeditions, SEM analysis, petrography, and a comprehensive review of international literature. It is intriguing to observe that in both cases, Pumapunku /Tiwanaku in the Andes and Easter Island, volcanic rocks are involved which contain biological carbon. These discoveries undeniably support the theory of geopolymeric artificial manufacturing, challenging traditional archaeological views.

Book Description
In this book, Professor Joseph Davidovits explains the intriguing theory that made him famous. He shows how the Pyramids were built by using re-agglomerated stone (a natural limestone treated like a concrete), and not with huge carved blocks, hauled on fragile ramps. Archaeology bears him out, as well as hieroglyphic texts, scientific analysis, religious and historical facts. Several independant scientific studies reveal the ultimate proofs that the pyramids blocks are not natural. You may find various papers or opinions challenging the theory, but all prefer ignoring these analysis. Believing or not in the artificial stone theory is now simply irrelevant. It is a fact, a truth that is still fought by some people for irrational purposes. Here we finally have the first complete presentation on how and why the Egyptian pyramids were built. We discover its brilliant creator, the great scribe and architect, Imhotep. Joseph Davidovits sweeps aside the conventional image which cripples Egyptology and delivers a captivating and surprising view of Egyptian civilisation. He charts the rise of this technology, its apogee with the Pyramids at Giza, and the decline. Everything is logical and brilliant, everything fits into place. Chapter by chapter, the revelations are sensational, especially when Joseph Davidovits explains why the pharaohs stopped building great pyramids because of an over-exploitation of raw materials and a likely environmental disaster. We understand why Cheops and Ramses II represent two Egyptian civilisations completely different in their beliefs. On the one hand, the God Khnum mandates Cheops to build his pyramid in agglomerated stone, while on the other hand, the God Amun orders Ramses to carve stone for the temples of Luxor and Karnak. 30 years after the best seller book: The Pyramids: an enigma solved, after 30 years of new research, and new discoveries, you will understand why the theory is more alive than ever, why more and more scientists and archaeologists agree, simply because it is the truth.

Book Description
The pyramids of Egypt have remained one of the oldest and most puzzling mysteries of mankind. Until now, no one, Egyptologists included, has satisfactorily explained how the pyramids were built. The traditional theory explaining that long lines of workers hoisted and dragged massive blocks up enormous ramps does not adequately address the hazards and complexities that make such an operation highly unlikely, especially since hundreds of the largest blocks in the pyramids are situated at great heights. The uncanny fit of blocks, as close as 1/500th of an inch, puzzles Egyptologists. Hard metals, such as iron and bronze, were not yet developed to produce good stone-cutting tools. Logistical problems of constructing the Great Pyramid are staggering and have never been reconciled; the scale and perfection is too grand. During the 20-year reign of the pharaoh who built it, about 2 1/2 million blocks were produced and perfectly assembled. As scientific methods of investigation become more sophisticated, the list of enigmas lengthens and more questions are raised than answered. Dr. Joseph Davidovits, research chemist and founder of the chemistry of geopolymerization, has solved the mystery. He has recovered the great, forgotten technology used to build the pyramids. His discovery is so dramatic and far reaching in scope that major aspects of ancient history will require rethinking. This technology and proof of its use in ancient Egypt are vividly and convincingly presented in the Pyramids: An Enigma Solved. Our concept of ancient Egypt will never be the same! -- Dust jacket.

Book Description
This book makes the case for why we should care about islands and their sustainability. Islands are hotspots of biocultural diversity and home to 600 million people that depend on one-sixth of the earth’s total area, including the surrounding oceans, for their subsistence. Today, they are at the frontlines of climate change and face an existential crisis. Islands are, however, potential “hubs of innovation” that are uniquely positioned to be leaders in sustainability and climate action. This volume argues that a full-fledged program on “island industrial ecology” is urgently needed, with the aim of offering policy-relevant insights and strategies to sustain small islands in an era of global environmental change. The nine contributions in this volume cover a wide range of applications of socio-metabolic research, from flow accounts to stock analysis and their relationship to services in space and time. They offer insights into how reconfiguring patterns of resource use will allow island governments to build resilience and adapt to the challenges of climate change.

Book Description
Have we been visited by extraterrestrial beings? Did these “ancient aliens” contribute to the birth of human civilization? Do our ancient monuments contain evidence of their presence? The Ancient Alien Question reveals an array of astonishing truths, including: A radically different understanding of the pyramids and how they were constructed The origins of crystal skulls and how they were found The extraordinary stories behind monuments such as the Nazca lines and Puma Punku, and who built them How extraterrestrials came to our planet and the evidence that supports this Analyzing the historical and archaeological evidence, Philip Coppens demonstrates that there is substantial proof that our ancestors were far more technologically advanced than currently accepted, and that certain cultures interacted with non-human intelligences. Our ancestors were clearly not alone. Forty years after Erich von Däniken posed these questions in Chariots of the Gods, Coppens provides clear and concise answers to the great historical enigmas in a most accessible and readable format. Your view of human history will never be the same again!

Book Description
The world's most artful and skillful stone architecture is found at Tiahuanaco at the southern end of Lake Titicaca in Bolivia. The precision of the stone masonry rivals that of the Incas to the point that writers from Spanish chroniclers of the sixteenth century to twentieth-century authors have claimed that Tiahuanaco not only served as a model for Inca architecture and stone masonry, but that the Incas even imported stonemasons from the Titicaca Basin to construct their buildings. Experiments aimed at replicating the astounding feats of the Tiahuanaco stonecutters--perfectly planar surfaces, perfect exterior and interior right angles, and precision to within 1 mm--throw light on the stonemasons' skill and knowledge, especially of geometry and mathematics. Detailed analyses of building stones yield insights into the architecture of Tiahuanaco, including its appearance, rules of composition, canons, and production, filling a significant gap in the understanding of Tiahuanaco's material culture.
