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!"

Fred Whipple

Died 30 Aug 2004 at age 97 (born 5 Nov 1906).Fred Lawrence Whipple was an American astronomer who proposed the “dirty snowball” model for comet nuclei. In the 1930s, using a new, two-station method of photography, he determined meteor trajectories and found that nearly all visible meteors are made up of fragile material from comets, and that none come from beyond the solar system. Whipple suggested (1950) that comets have icy cores inside thin insulating layers of dirt, and that jets of material ejected as a result of solar heating were the cause of orbital changes. This model was confirmed in 1986 when spacecraft flew past comet Halley. Whipple's work on tracking artificial satellites led to improved knowledge of the shape of the earth and greatly improved positions on earth.
