Intervention: How Humanity from the Future Has Changed Its Own Past
The metal revolution The development of humanity's mastery over metal is a mystery, since the required temperatures for smelting metal exceeded anything that Neolithic man would have needed for any purpose. So how and why did smelting start? Add to that the fact that the first usable metal, bronze, is an alloy of copper and the much rarer tin and we begin to see the scale of the puzzle. Intervention supplies a convincing answer. The megalithic yard Neolithic peoples created a sophisticated, fully integrated system of measurements based on the actual size and mass of the Earth - a 'marker' for future scientific developments, surfacing again, apparently out of the blue, in 18th-century Washington, DC. But the most spectacular revelation lies in our future. By looking at the mathematics underlying many of the inventions, we discover, with unexpected precision, when our first contact with our future selves will happen. This will occur within the lifetime of most readers of this extraordinary book.
