History of Iron and Steel I have researched the origin of hot metal cars for many years. In the very early years of iron production and later steel production historical is sketchy at best. Almost in plant equipment was built on sight and sometimes no drawings were used. The ability of American fabricators in the late 1700 and the 1800 amazes me. A case in point is Otto Mears a German immigrant that built most of the three foot gauge railroads in the Colorado Rockies. He had a third grade education

People such as farmers were turned in serfs. This was a portrait of what might be to come from an oligarchy type of government

It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are

Iron Man: The Real Hero In today’s society‚ the concern of people and laws are not about doing good but rather having the appearance of good. People no longer care about what they need to stand for‚ only that they look like they aren’t sitting down.
