Laying Turf

A painting contractor was speaking with a woman about a job. In the first room, she said she would like a pale blue. The contractor wrote this down and went to the window, opened it, and yelled out "GREEN SIDE UP!" In the second room, she told the painter she would like it painted in a soft yellow. He wrote this on his pad, walked to the window, opened it, and yelled "GREEN SIDE UP!" The lady was somewhat curious but she said nothing. In the third room, she said she would like it painted a warm rose color. The painter wrote this down, walked to the window, opened it and yelled "GREEN SIDE UP!" The lady then asked him, "Why do you keep yelling 'green side up'?"

"I'm sorry," came the reply.

"But I have a crew of blondes laying sod across the street."

1,000th pulsar

In 1998, the discovery of the 1,000th pulsar in our galaxy was announced in a press release by the Jodrell Bank Observatory, University of Manchester, using the 64-meter Parkes Radio Telescope in New South Wales, Australia. A “multibeam”receiver was installed on the telescope in early 1997. This allowed the astronomers from England, Australia, United States, and Italy to find pulsars much faster than before. On average, they found a new pulsar in every hour of observing. By this date, the researchers had found more than 200 pulsars and they expected to find another 600 more before the survey ended. The “multibeam”receiver used consists of 13 hexagonally arranged receivers that allow simultaneous observations.
