In 2006, 362 people died in the crush at Mina, where pilgrims gathered to perform the ritual. However, this year's ritual, which happened in late December and early January, went off without any incident.
So what was it, pure luck? Certainly not; according to Dirk Helbing of the Dresden University of Technology, Germany, it was sound planning based on the study of crowd dynamics that helped prevent casualties during one of Islam's most holiest traditions.
The problem began Tuesday afternoon, blocking several European, Middle East and northeast African radio and television stations, as well as Agence France-Presse's news service. All transferred their satellite transmissions to another frequency to resume operations.

A simple calculation to give the expected temperature of a planet's upper atmosphere balances the amount of sunlight absorbed by the energy lost to the lower atmosphere. But the calculated values don't tally with the actual observations of the Gas Giants: they are consistently much hotter.
It has long been thought that the culprit behind the heating process was the ionosphere, being driven by the planet's magnetic field, or magnetosphere. By using numerical models of Saturn's atmosphere the researchers found that the net effects of the winds driven by polar energy inputs is not to heat the atmosphere but to actually cool it.

Lu told an audience at the University of Hawaii-Manoa Monday evening the 200 million U.S. dollar to 300 million dollar spacecraft would exert enough gravitational pull to alter an astroid's orbit.
"We're only trying to get a really tiny change in the velocity of the asteroid to prevent an impact," said Lu, a former University of Hawaii solar physicist.
The new weapon had its first media demonstration Wednesday.
Comment: Weapons like these are being built to be used against dissidents at home. You can take that to the bank.

The so-called Active Denial System creates an intense burning sensation causing people to run for cover, but no lasting harm, officials said.
