A little girl is sitting on he...

A little girl is sitting on her grandpa's lap and studying the wrinkles on his old face. She gets up the nerve to rub her fingers over the wrinkles. Then she touches her own face and looks more puzzled. Finally the little girl asks, "Grandpa, did God make you?"
"He sure did honey, a long time ago," replies her grandpa.
"Well, did God make me?" asks the little girl.
"Yes, He did, and that wasn't too long ago," answers her grandpa.
"Boy," says the little girl, "He's sure doing a lot better job these days isn't He?"

National light-pollution law

In 2002, the first national law prohibiting "light pollution" went into effect. The Czech Republic became the first nation to outlaw excess outdoor light. All outdoor light fixtures in the country must be shielded to ensure light goes only in the direction intended, and not above the horizontal. Czech astronomers had lobbied for the legislation. Light from street and road signs bounces off molecules in the atmosphere, making skies less dark. This light pollution is a particular problem for astronomers since even low levels of man-made light from distant cities can obscure their view of faint objects far away in space. Better designed, non-polluting light fixtures should give everyone better more energy efficiency and reduce glare on roads and in residential areas.[Image: Skyglow 120km north of Adelaide, Australia.]
