Wish granted???

A couple had been married for 35 years, and the pair was also celebrating their 60th birthdays. During the celebration, a fairy godmother appeared and said that because they had been such a loving couple all those years, she would give them each one wish.

The wife said she wanted to travel around the world. The fairy godmother waved her magic wand and BOOM! The wife had the tickets in her hand.

Then it was the husband's turn. He paused for a moment, then said boldly, "Well, I'd like to have a wife 30 years younger than I." The fairy godmother picked up her wand and BOOM! He was now 90.

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.
