I tend to believe the human occupation to be about 1.28 million bce

Charlie, you need to put dates on all these rocks. pre-clovis just doesn't cut it anymore.


It's inwork, Bro.

Yeah, I agree, preClovis is way to broad of a description, we're finding out. We've got stuff at Cactus Hill and Meadowcroft that has an European, Upper Paleolithic look to it. Then we've got stuff at Topper, Hueyatlaco, Calico and the site I'm researching that has an African look to it: both Early and Middle Stone Age.

No. 2 Fe Smelting Around 3500 B.C., Egyptians smelt iron for the first time, using tiny amounts, mostly for ornamental or ceremonial purposes. This is the first processing secret of what will become the world's dominant metallurgical material.

No. 3 Transistor In 1948, John Bardeen, Walter H. Brattain and William Shockley invent the transistor. This becomes the building block for all modern electronics and the foundation for microchip and computer technology.

No. 4 Invention of Glass Approximately 2200 B.C., northwestern Iranians invent glass. This becomes the second greatest nonmetallic engineering material (following ceramics).

No. 5 Optical Microscopy In 1668, Anton van Leeuwenhoek develops optical microscopy, capable of magnifications of 200 times and greater. This enables study of the natural world invisible to the human eye.

No. 6 Modern Concrete In 1755, John Smeaton invents modern concrete (hydraulic cement), which introduces the dominant construction material of the modern age.

No. 7 Crucible Steel Making Around 300 B.C., metal workers in south India develop crucible steel making, which produces "wootz" steel. This becomes famous as Damascus sword steel hundreds of years later, inspiring artisans, blacksmiths and metallurgists for many generations.

No. 8 Cu Extraction and Casting Approximately 5000 B.C., people in the region of modern Turkey discover that liquid copper can be extracted from malachite and azurite, and that the molten metal can be cast into different shapes. Extractive metallurgy is introduced.

No. 9 X-ray Diffraction In 1912, Max von Laue discovers the diffraction of x-rays by crystals. This creates the means to characterize crystal structures and inspires the development of the theory of diffraction by crystals.

No. 10 Bessemer Process In 1856, Henry Bessemer patents a bottom-blown acid process for melting low-carbon iron. This leads to the era of cheap, large tonnage steel, enabling massive progress in transportation, building construction and general industrialization.

If your serious enough about it, you might even write a paper about your experiments and take a shot at publishing it...never know.

In addition, they showed a projected SEA ROUTE.
