A young woman asks her mother, "Mom, how many kind of penises are there?"
The mother, surprised, answers, "Well, daughter, a man goes through three phases. In a man's twenties, a man's penis is like an oak, mighty and hard. In his thirties and forties, it is like a birch, flexible but reliable. After his fifties, it is like a Christmas tree."
"A Christmas tree?" the young woman asks.
"Yes, dried up and the balls are there for decoration only."
Airy Transit CircleIn 1850, the Airy Transit Circle was first used at the Royal Observatory, Greenwich. The instrument was designed by George Biddell Airy, the Astronomer Royal. It was set up on the Prime Meridian - the north-south line of longitude 0° - which marks the start of the Universal day for the world. The time at which a star passed over the meridian was measured with a regulator (an extremely accurate clock). The transit was used to measure the angle of a star at that instant. From this data, the co-ordinates of that star could be determined and plotted on a star chart. Navigation at sea depended on the accuracy of these charts, and the Airy Transit Circle was a great improvement on the previous technology.« |
