How was your game, dear?

"How was your game, dear?" asked Jack's wife Tracy. 
"Well, I was hitting pretty well, but my eyesight's gotten so bad I couldn't see where the ball went," he answered. 
"But you're 75 years old, Jack!" admonished his wife, "Why don't you take my brother Scott along?" 
"But he's 85 and doesn't play golf anymore," protested Jack. 
"But he's got perfect eyesight. He would watch the ball for you," Tracy pointed out. 
The next day Jack teed off with Scott looking on. Jack swung and the ball disappeared down the middle of the fairway. "Do you see it?" asked Jack. 
"Yup," Scott answered. 
"Well, where is it?" yelled Jack, peering off into the distance. 
"I forgot."

Cosmic rays generate electricity

In 1939, cosmic rays entering a Geiger-Mueller counter produced electrical impulses used to control electrical power. This first ever such event, was used for the illumination ceremony of the 1939 New York World's Fair. The counter, at the Hayden Planetarium, New York City, switched on an electrical circuit wired to a display at the Lagoon of Nations where relays activated local battery circuits ringing bells and flashing lights to signal each capture of a cosmic ray. Albert Einstein as guest speaker explained cosmic rays. Sadly his accent and faulty amplification made his words incomprehensible to the crowd. Upon the tenth ray's signal, a huge light was to be turned on to illuminate the 600-ft Trylon triangular spire, but the power source failed.«[Image: Trylon spire.]
