Radioactivity

In 1896, Henri Becquerel read a report to the French Academy of Sciences of his investigation of the phosphorescent rays of some “double sulfate of uranium and potassium” crystals. He reported that he placed the crystals on the outside of a photographic plate wrapped in sheets of very thick black paper and exposed the whole to the sun for several hours. When he developed the photographic plate, he saw a black silhouette of the substance exposed on the negative. When he placed a coin or metal screen between the uranium crystals and the wrapped plate, he saw images of those objects on the negative. He did not yet know yet that the sun is not necessary to initiate the rays, nor did he yet realise that he had accidentally discovered radioactivity. He would learn more from a further accidental discovery on 26 Feb 1896.

Toilet Paper

A little old lady goes into the store to do some shopping. She is bewildered over the large selection of toilet paper.
"Pardon me, sir," she says to the store manager, "but can you explain the differences in all these toilet papers?"
"Well," he replies pointing out one brand, "this is as soft as a baby's kiss. It's $1.50 per roll."
He grabs another and says, "This is nice and soft as a bunny, strong but gentle, and it's $1.00 a roll."
Pointing to the bottom shelf he tells her, "We call that our No Name brand, and it's 20 cents per roll."
"Give me the No Name," she says.
She comes back about a week later, seeks out the manager and says, "Hey! I've got a name for your No Name toilet paper. I call it John Wayne."
"Why?" he asks.
"Because it's rough, it's tough and it don't take crap off anybody!"
