A woman was sure that her husband was cheating on her, and having an affair with the maid. So she laid down a trap.
One evening she suddenly sent the maid home for the weekend and didn't tell the husband.
That night when they went to bed, the husband gave the old story: Excuse me my dear, my stomach aches, and went to the bathroom.
The wife promptly went into the maid's bed. She switched the lights off. When he came in silently, he wasted no time or words but quickly got on top of her...
When he finished and was still panting, the wife said: "You didn't expect to find me in this bed, did you?" And then she switched on the light...
"No madam," said the gardener.

Neptunium

In 1940, discovery of element 93, neptunium (symbol Np) was announced by Edwin M. McMillan and Philip H. Abelson working at the University of California at Berkeley. While studying nuclear fission, McMillan had discovered neptunium as a decay product of uranium-239 by beta decay. They were able to prove that its chemical and nuclear properties were unique, and thus a new element. Its later isolation in metallic form (Oct 1944) provided final proof. It was named neptunium after Neptune, the planet immediately beyond Uranus. As the first element heavier than uranium, it was called a transuranium element. For his discovery, McMillan was awarded a share of the Nobel Prize for Chemistry in 1951. Later, when discovered, element 94 was named plutonium, for the planet beyond Neptune.«[Image: McMillan recreating the search for neptunium at the time of the announcement of the discovery]
