Parking the car....
Joe and Joan were sitting down to their usual morning cup of coffee listening to the weather report on the radio. "There will be 3 to 5 inches of snow today, and a snow emergency has been declared," the weather report said.
"You must park your cars on the odd numbered side of the streets."
Joe said, "Jeez, okay," and got up from his coffee.
The next day they were sitting down with their morning cups of coffee. The weather forecast was, "There will be 2 to 4 inches of snow today, and a snow emergency has been declared.
You must park your cars on the even numbered side of the streets." Again Joe replied, "Jeez, okay," and got up from his coffee.
Two days later, again they're sitting down with their cups of coffee and the weather forecast said, "There will be 6 to 8 inches of snow today, and a snow emergency has been declared. You must park your cars on the..." and the power went out and Joe didn't get the rest of the instructions.
He turned to Joan, "Jeez, what am I going to do now, Joan?"

MAGIC SQUARE: Calculate A-B*C
The aim is to place the some numbers from the list (11, 13, 17, 18, 19, 20, 22, 24, 27, 72) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B*C.
SupernovaIn 1181, a supernova was observed by Chinese astronomers in the constellation now known as Cassiopeia, and noted one day later from Japan. Ancient records of Chinese court astronomers reported“a guest star appearing in k'uei invading the Ch'uan-she-hsing”and that it remained visible for 185 days (over 6 months). A supernova remnant, now named 3C58, found by radio astronomers in the 1960s, was first proposed to be the remnant of the supernova 1181 by F. Richard Stephenson. The associated radio and X-ray pulsar rotates sedately at about 15 times per second. Stephenson wrote in 2006 that this supernova is one of only five temporary stars observed in the past 1500 years that have been confidently identified.«[Image: four-day X-ray observation of 3C58 by the Chandra X-ray Observatory, shown in pseudo colour with red representing low energy X-rays and blue for high energy.] |
