Ex-Girlfriend

A man and his wife are dining at a table in a plush restaurant, and the husband keeps staring at a drunken lady swigging her drink as she sits alone at a nearby table.
The wife asks, "Do you know her?"
"Yes," sighs the husband, "she's my ex-girlfriend. I understand she took to drinking right after we split up seven years ago, and I hear she hasn't been sober since."
"My God!" says the wife. "Who would think a person could go on celebrating that long?"

Peter Dollond

Died 2 Jul 1820 (born 1730).British optician, son of John Dollond. Peter, though lacking a theoretical background, invented the triple achromatic lens still in wide use, made substantial improvements in the astronomical refracting telescope, and improved navigation instruments of his day. In 1765, he placed convex lenses of crown glass on either side of a biconcave flint glass lens to make the achromatic triplet lens to further improve the correction of colour fringes. (In 1733, Chester Moore Hall had invented the achromatic lens system by joining a crown glass lens and a flint glass lens, which reduce chromatic aberration.)
