White hairs

One day, a girl walks to her mother and look at her mother's hair and sadly said: "Why are some of your hair white mom?"

The mother replied, "Well, every time that you do something wrong and make me cry or unhappy, one of my hairs turns white.

The girl thought about this revelation a while, and then said, "Momma, how come *all* of grandma's hairs are white?"

While a Kentucky manufacturer of iron kettles, he discovered that cold air blown on red-hot iron caused the metal to become white-hot by igniting the carbon and thus eliminating impurities. He applied his “air boiling”technique to his own product, but his customers decried “Kelly's fool steel,”and his business declined. In a legal fight, by asserting his practical efforts investigating the process had been carried out earlier in time, his belated patent of 23 Jun 1857 won priority over the U.S. patent of Sir Henry Bessemer of Great Britain. However, Kelly's invention was only a first step. They jointly licenced their patents. Bessemer's further developments were more successful. The Bessemer-Kelly process won acceptance, produced the first inexpensive steel, and furthered the industrial age.«
