All I Need is a Miracle

A woman was walking along the beach when she stumbled upon a genie's lamp. She picked it up and rubbed it. Lo-and-behold a genie appeared. The amazed woman asked if she got three wishes.
The Genie said, "Nope. Due to inflation, constant downsizing, low wages in third-world countries and fierce global competition, I can only grant you one wish. So, what'll it be?"
The woman didn't hesitate. She said, "I want peace in the Middle East. See this map? I want these countries to stop fighting with each other."
The Genie looked at the map and exclaimed, "Gadzooks, lady! These countries have been at war for thousands of years. I'm good, but not THAT good! I don't think it can be done. Make another wish."
The woman thought for a minute. She said, "Well, I've been trying to find the right husband. You know, one that's considerate and fun, likes to cook and helps with the housecleaning, has a great sense of humor and gets along with my family, doesn't watch sports all the time and is faithful. That's what I wish for. A good mate."
The Genie let out a long sigh and said, "Let me see that map again."

Telescope lens

In 1947, after 11 years of grinding and polishing a 200-inch diameter telescope lens for the Mount Palomar Observatory was completed at the California Institute of Technology. This lens, the first of its size made in the U.S., began when 20 tons of molten glass at 2,700 deg. Fahrenheit were poured into a ceramic mold at Corning Glass Works, N.Y. on 2 Dec 1934. The glass lens was allowed to cool only one or two degrees per day over the next eleven months, and then brought to room temperature. The telescope in which the lens was mounted was named the Hale Telescope in recognition of the late Dr. George E. Hale who had initiated the project. The completed telescope was first used on 1 Feb 1949 by taking pictures of a Milky Way constellation.
