Sunspot

In 1947, the largest sunspot group recorded was observed on the sun's southern hemisphere. Its size was estimated at 7 billion square miles, or an area of 6100 millionths of the Sun's visible hemisphere. Sunspots are areas of somewhat cooler surface than the surrounding solar gases, and appear as dark spots on the solar surface. Astronomers measure the sizes of sunspots as millionth fractions of the Sun's visible area. Typically, a big sunspot measures 300 to 500 millionths, whereas the entire surface area of the Earth is only 169 millionths of the solar disk.

Three men were discussing at a bar about coincidences. The first man said, " my wife was reading a "tale of two cities" and she gave birth to twins"
"That’s funny", the second man remarked, "my wife was reading 'the three musketeers' and she gave birth to triplets"
The third man shouted, "Good God, I have to rush home!"
When asked what the problem was, he exclaimed, " When I left the house, my wife was reading Ali baba and the forty Thieves"!!!
