Singing In Church

A minister decided to try something a little different one Sunday morning.
He said, "Today, in church, I am going to say a single word and you are going to help me preach. Whatever single word I say, I want you to sing whatever hymn comes to your mind."
The pastor shouted out, "Cross!"
Immediately the congregation started singing in unison "The Old Rugged Cross."
The pastor hollered out, "Grace!" The congregation began to sing "Amazing Grace, how sweet the sound."
The pastor said, "Power!" The congregation sang "There is Power in the Blood."
The Pastor said, "Sex!"
The congregation fell in total silence. Everyone was in shock. They all nervously began to look around at each other, afraid to say anything. Then all of a sudden, from the back of the church, a little old 87-year-old grandmother stood up and began to sing "Precious Memories."

Tungsten filaments

In 1913, Dr William David Coolidge patented (U.S. No. 1,082,933) a method for making ductile tunsten for the purpose of making filaments for electric lamps. When Coolidge joined the General Electric Research Laboratory (1905), he was given the task of replacing the fragile carbon filaments in electric light bulbs with tungsten filaments, although tungsten was difficult to work. He developed a way to superheat the metal tunsten in order to draw it out into the fine threads used for lamp filaments. Coolidge then improved the X-ray tube by using a heated tungsten filament cathode in vacuum producing electrons, instead of residual gas molecules in the tube. This permitted higher operating voltages, higher energy X rays and the treatment of deeper-seated tumors.
