Thousands of geniuses live and die undiscovered — either by themselves or by others. But for the Civil War, Lincoln and Grant and Sherman and Sheridan would not have been discovered, nor have risen into notice. … I have touched upon this matter in a small book which I wrote a generation ago and which I have not published as yet — Captain Stormfield’s Visit to Heaven. When Stormfield arrived in heaven he … was told that … a shoemaker … was the most prodigious military genius the planet had ever produced.
Mark Twain
- Lead (Wikipedia)
Lead is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements.
