On a day lost to history, some fortuitous humans found a glistening meteorite, mostly iron and nickel, that had barreled through the atmosphere and crashed into the ground. Thus began an obsession that gripped the species. Over the millennia, our ancestors would work the material, discovering better ways to draw iron from the Earth itself and eventually to smelt it into steel. We’d fight over it, create and destroy nations with it, grow global economies by it, and use it to build some of the greatest inventions and structures the world has ever known.
I now know more about steel than I ever did and I had fun reading this very accessible article with my 12 year old.
