Metals and How to Weld Them (1954) by T.B. Jefferson and Gorham Woods is a practical manual which describes the structure of various metals used in industry, their mechanical and physical properties, and the processes and procedures necessary for welding them.

Geneticists like David Reich have made astounding advances in the field of genomics, which is proving to be as important as archaeology, linguistics, and written records as a means to understand our ancestry. In Who We Are and How We Got Here, Reich allows listeners to discover how the human genome provides not only all the information a human embryo needs to develop but also the hidden story of our species.

Stunning new archaeological discoveries in North America together with new genetic evidence have launched a revolution in our understanding of the remote past of our species and of the origins of civilization. Graham Hancock, the internationally best-selling author has been overwhelmingly vindicated by recent discoveries. America Before: The Key to Earth's Lost Civilization is a mind-dilating exploration of the mystery of ancient civilizations, amazing archaeological discoveries, and profound implications for how we lead our lives today.

The Viking Age - from 750 to 1050 saw an unprecedented expansion of the Scandinavian peoples into the wider world. As traders and raiders, explorers and colonists, they ranged from eastern North America to the Asian steppe. But for centuries, the Vikings have been seen through the eyes of others, distorted to suit the tastes of medieval clerics and Elizabethan playwrights, Victorian imperialists, Nazis, and more. None of these appropriations capture the real Vikings, or the richness and sophistication of their culture.

This classic presents historical, archaeological, and anthropological evidence to support the theory that ancient Egypt was a black civilization.

Guyanese intellectual Walter Rodney emerged as one of the leading thinkers and activists of the anticolonial revolution. In 1980, shortly after founding of the Working People's Alliance in Guyana, the 38-year-old Rodney would be assassinated. In his magnum opus, Rodney incisively argues that grasping "the great divergence" between the West and the rest can only be explained as the exploitation of the latter by the former. This meticulously researched analysis of the repercussions of European colonialism in Africa remains an indispensable study for grasping global inequality today.

Today's view of history cannot account for ancient anomalies, such as the Pyramids and advanced knowledge contained in India's Vedas. But in 1894, an Indian sage gave us an explanation not only for our hidden past but for the trends of today and for our future enlightenment - the 24,000-year yuga cycle.

Origin is the story of who the first peoples in the Americas were, how and why they made the crossing, how they dispersed south, and how they lived based on a new and powerful kind of evidence: their complete genomes. Origin provides an overview of these new histories throughout North and South America, and a glimpse into how the tools of genetics reveal details about human history and evolution.

Whether it is true or not that not more than 12 persons in all the world are able to understand Einstein's Theory, it is nevertheless a fact that there is a constant demand for information about this much-debated topic of relativity. The books published on the subject are so technical that only a person trained in pure physics and higher mathematics is able to fully understand them. In order to make a popular explanation of this far-reaching theory available, the present book was written.

In ancient, pre-literate cultures across the globe, tribal elders had encyclopedic memories. They could name all the animals and plants across a landscape, identify the stars in the sky, and recite the history of their people. Yet today, most of us struggle to memorize more than a short poem. Using traditional Aboriginal Australian song lines as a starting point, Dr. Lynne Kelly has since identified the powerful memory technique used by our ancestors and indigenous people around the world.

Tracing the migrations of the Denisovans and their interbreeding with Neanderthals and early human populations in Asia, Europe, Australia, and the Americas, Andrew Collins and Greg Little explore how the new mental capabilities of the Denisovan-Neanderthal and Denisovan-human hybrids greatly accelerated the flowering of human civilization over 40,000 years ago. They show how the Denisovans displayed sophisticated advances, including precision-machined stone tools and jewelry, tailored clothing, celestially-aligned architecture, and horse domestication.

Technology has grown greatly in the recent past from self-driving cars to automated warehouses to websites being able to suggest what videos we should watch next based on our preferences to showing us ads that relate to things we are interested in and the world we are living in these days. It is, perhaps, like a sci-fi scene from movies of some decades ago.

This audiobook is the conclusive history of the field of artificial intelligence (AI), following its history from the fantasies of early pioneers to the more effective work of the present AI engineers. The audiobook incorporates numerous outlines and straightforward depictions of AI programs that will enable the easygoing per user to increase a comprehension of how these and other AI frameworks really work. The work was written especially for beginners. The topic is treated with simplicity and it is easy to read and understand.

In this engaging exploration, archaeologist Ian Hodder departs from the two prevailing modes of thought about human evolution: the older idea of constant advancement toward a civilized ideal and the newer one of a directionless process of natural selection. Instead, he proposes a theory of human evolution and history based on "entanglement," the ever-increasing mutual dependency between humans and things.

In recent years, the common perception of the Neanderthals has been transformed, thanks to new discoveries and paradigm-shattering scientific innovations. It turns out that the Neanderthals' behavior was surprisingly modern: they buried the dead, cared for the sick, hunted large animals in their prime, harvested seafood, and communicated with spoken language. Meanwhile, advances in DNA technologies are compelling us to reassess the Neanderthals' place in our own past.
