The teacher noticed that Johnny had been day dreaming for a long time. She decided to get his attention."Johnny," she said, "If the world is 25,000 miles around and eggs are sixty cents a dozen, how old am I? "Thirty-four," Johnny answered unhesitatingly.
The teacher replied "Well, that's not far from my actual age. Tell me...how did you guess?"
Oh, there's nothing to it," Johnny said. "My big sister is seventeen and she's only half-crazy."

Indian satellite

In 1975, the first satellite built in India was launched from Volgograd Launch Station, Russia, on a Soviet Intercosmos C-1 rocket. It was named Aryabhata, after a noted 5th-century Indian mathematician. The 360-kg satellite had been built during 20 months by the Indian Space Research Organization (ISRO) in Peenya, Bangalore, by a team led by Prof. U. R. Rao. Its shape was a 26-sided polygon, 1.4-m diam., with all faces covered in solar cells, except the top and bottom. It was designed to carry out experiments in X-ray astronomy, aeronomics, and solar physics, communicating with a 46-watt VHF transmitter. However, after only 4 days in orbit, a power failure ended any further experiments. It remained in orbit nearly 17 years, until it reentered the Earth's atmosphere on 11 Feb 1992.«
