President Obama and David Cameron...

President Obama and David Cameron are shown a time machine which can see 100 years into the future. They both decide to test it by asking a question each.
President Obama goes first: "What will the USA be like in 100 years time?"
The machine whirrs and beeps and goes into action and gives him a printout. He reads it out: "The country is in good hands under the new president, crime is non-existent, there is no conflict, the economy is healthy. There are no worries."
David Cameron thinks, "It's not bad time machine, I'll have a bit of that." So he asks: "What will Britain be like in 100 years time?"
The machine whirrs and beeps and goes into action, and he gets a printout.
But he just stares at it.
"Come on David," says Obama, "Tell us what it says."
"I can't! It's all in Arabic!"

Karl Jansky

Born 22 Oct 1905; died 14 Feb 1950 at age 44.Karl Guthe Jansky was an American electrical engineer who discovered cosmic radio emissions in 1932. At Bell Laboratories in NJ, Jansky was tracking down the crackling static noises that plagued overseas telephone reception. He found certain radio waves came from a specific region on the sky every 23 hours and 56 minutes, from the direction of Sagittarius toward the center of the Milky Way. In the publication of his results, he suggested that the radio emission was somehow connected to the Milky Way and that it originated not from stars but from ionized interstellar gas. At the age of 26, Jansky had made a historic discovery - that celestial bodies could emit radio waves as well as light waves.
