What would I do if I could change the world? It's an interesting question. The first thing I would do if I could change the world is distribute money evenly to all the countries so no one would be in poverty. I would ban cigarettes but do it in a way that nobody will get angry or sad.The thing I would do to change the world is to give everyone a house and an education or occupation. I would also put a cheap supermarket near every village or city.I am already living my dream, doing what I would do if I could change the world. And if I don’t succeed in changing the world, I know that I have changed my own world. I have become the man of my dreams.
The first signs of iron use come from Ancient Egypt, where around 4000BC small items. About 6% of meteorites are composed of an iron-nickel alloy.Meteoric iron was also fashioned into tools in North America. Beginning around the year 1000, the people of Greenland began making harpoons. These artifacts were also used as trade goods with other Arctic peoples: tools made from the Cape York
The oldest known samples of iron that appear to have been smelted from iron oxides. Some iron oxides are effective fluxes for copper smelting; it is possible. In Anatolia, smelted iron was occasionally used for ornamental weapons.
Then, between 1200 BC and 1000 BC, iron tools and weapons displaced bronze ones throughout the near east. This process appears to have begun in the Hittite Empire around 1300 BC. Iron smelting at this time was based on the bloomery, a furnace where bellows were used to force air through iron ore and burning charcoal. The carbon monoxide produced by the charcoal reduced the iron oxides to metallic iron,The bloom then had to be reheated to soften the iron and melt the slag, and then repeatedly beaten and folded to force the molten slag out of it.
The result of this time-consuming and laborious process was wrought iron, a malleable but soft alloy containing little carbon. . By the beginning of the Iron Age, smiths had discovered iron.
