An older couple had a son, who...

An older couple had a son, who was still living with them.The parents were a little worried, as the son was still unableto decide about his career path, so they decided to do a smalltest.
They took a ten-dollar bill, a Bible, and a bottle of whiskey,and put them on the front hall table. Then they hid, hopinghe would think they weren't at home.
The father told the mother, "If he takes the money, he will bea businessman; if he takes the Bible, he will be a priest; butif he takes the bottle of whiskey, I'm afraid our son will bea drunkard."
So the parents took their place in the nearby closet and waitednervously, peeping through the keyhole they saw their sonarrive home.
He saw the note they had left, saying they'd be home later.Then, he took the 10-dollar bill, looked at it against thelight, and slid it in his pocket. After that, he took theBible, flicked through it, and took it also. Finally, hegrabbed the bottle, opened it, and took an appreciative whiffto be assured of the quality, then he left for his roomcarrying all the three items.
The father slapped his forehead, and said, "Damn! It's evenworse than I ever imagined..."
"What do you mean?" his wife inquired.
"He's gonna be a politician." the father replied.

Percy Gilchrist

Born 27 Dec 1851; died 16 Dec 1935 at age 83.Percy Carlyle Gilchrist was an English metallurgist who is known for the Thomas-Gilchrist process (1876-77) he developedwhile assistant to his cousin, Sidney Gilchrist Thomas. This process manufactured low-phosphorus steel known as Thomas steel, in Bessemer converters and was adopted throughout Europe where iron ore has phosphorus impurities. The key feature of this process is the use of lime (calcined dolomite) to line the converter instead of acidic silica. The lime is a base and it captures acidic phosphorus oxides produced when air is blown through the molten iron. The phosphorous content, which otherwise makes steel brittle, was reduced to about 0.04%. Additionally, the cinder waste product of the steelmaking could be used as valuable artificial fertilizer.«
