This married couple was sitting in a fine restaurant when the wife looks over at a nearby table and sees a man in a drunken stupor.
The husband asks "I notice you've been watching that man for some time now. Do you know him?"
"Yes" she replies. "He's my ex-husband and has been drinking like that since I left him seven years ago."
"That's remarkable" the husband replies. "I wouldn't think anybody could celebrate that long."
First refracting telescopeIn 1608, Johannes Lippershey (c.1570-c.1619) demonstrated a new invention, the first optical (refracting) telescope - prototype of the modern telescopes - to the Netherlands States General. Lippershey was a lens grinder who furnished spectables. An apprentice discovered that - by separating both a long-focus lens and a short-focus lens in front of the eye - distant objects appeared closer. Lippershey mounted lenses in tubes, applied for a patent in 1608, and also offered them for sale to the Dutch government, which appreciated their military value. When Galileo heard of the device, he made a similar arrangement and used it to study the heavens. It was named a "telescope" by a guest at an outdoor banquet 14 Apr 1611 honouring Galileo, where he demonstrated it to the assembly.« |
