A woman was sure that her husb...

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.

Achromatic lenses

In 1758, optician John Dolland, having created achromatic lenses, reported this to the Royal Society. Isaac Newton had described the blurring effect due to chromatic abberation, but could not solve the problem in simple lenses, which was important in the preparation of lenses for telescopes and microscopes. A concave face of a lens of flint glass (which has a greater color dispersion than crown glass) is cemented to a convex face of a crown glass lens. Thus the dispersion properties causing chromatic aberration are removed from both lenses simultaneously. Although Dollond patented the discovery of the achromatic lens in the mid-18th century, it is widely believed that he was not its inventor, but learned about it from lens maker George Bass.
