There were three little boys v...

There were three little boys visiting their grandparents.
The oldest came out and asked his grandpa, "Can you make a sound like a frog, Grandpappy?
Grandpa (being in a kind of ill mood) responds, "No, I don't really want to make the sound of a frog now."
So, the second little boy comes out and asks his grandfather, "Will you please make a sound like a frog?"
Grandpa again says, "No, not now. I don't really want to do that.I'm in a grumpy mood. Maybe later."
Then the third little boy comes out and says, "Grandpa, oh please...Please, please will you make a sound like a frog?"
"Why do all of you boys want me to make a sound like a frog?" Grandpa asked.
The little boy replied with a hopeful face, "Well, Mom said that when you croak, we get to go to Disney World!"

Willard Harrison Bennett

Died 28 Sep 1987 at age 84 (born 13 Jun 1903).Willard Harrison Bennett was an American physicist who discovered (1934) the pinch effect, an electromagnetic process that may offer a way to magnetically confine a plasma at temperatures high enough for controlled nuclear fusion reactions to occur. He proposed (1936) the tandem Van de Graaff accelerator, which later became widely used in nuclear research. He invented a radio-frequency mass spectrometer, developed in 1955. Since it required no heavy magnet, it was the first launched into space to measure the masses of atoms. Sputnik III carried the first R-F mass spectrometer into space. It was the only space instrument used by the Russians and credited to an American inventor in their own Russian-language publications.
