G.W. Bush
Gesto "nobile" di Bush: dopo aver stretto alcune mani tra la folla ad Haiti si pulisce la mano sulla camicia di Clinton:
Forse gli haitiani sono troppo neri.

chile earthquake
Chile quake Shifted Earth's axis, Shortened the lenght of a day
The devastating earthquake in Chile that killed almost 700 people probably also shifted the Earth’s axis, say NASA scientists, permanently making days shorter by 1.26 microseconds. But since a microsecond is one-millionth of a second, you may not have noticed.
Richard Gross, a geophysicist at NASA’s Jet Propulsion Laboratory, says he has done the calculations. Gross says the earthquake, which measured 8.8 on the Richter scale, moved large amounts of rock, altered the distribution of mass on the planet, and moved the Earth’s axis by about 2.7 milliarcseconds (about 8 centimeters or 3 inches). The change in axis directly impacts Earth’s rotation, and the rate of the planet’s rotation determines the length of a day.
To explain this phenomenon, scientists used an ice skating analogy: When a skater spins on ice, he draws his arms closer in to his body to spin faster, because the speed of his rotation is dependent on the way mass is distributed across his body.
Scientists point out that the duration of a day can change depending on different geological events.
