The School of Mathematics, University of Manchester finished moving in to its new building Monday. The building is named after one of its most widely known academics, Alan Turing, one of the founders of computer science and a Reader in Mathematics at Manchester.

Although Turing is one of the city and university’s most famous sons, there are very few things named in his honour. The city council was criticised for naming an uninspiring piece of by-pass Alan Turing Way, and a statue erected by public subscription bears a plaque pointing out the failure of the computing industry to contribute.

The new building deliberately attempts to provide a conducive atmosphere for mathematical collaboration with a design that aims to promote chance encounter in public spaces. It also aims to save energy with solar panels fitted to the roof.

The building also houses the Astronomy and Astrophysics Group, and the Photon Sciences Institute.

New Orleans, Louisiana —After Category 4 storm Hurricane Katrina slammed into New Orleans, on the night before August 29, 2005, several flood control constructions failed. Much of the city flooded through the openings. One of these was the flood wall forming one side of the 17th Street Canal, near Lake Pontchartrain. The U.S. Army Corps of Engineers (USACE) is the primary agency for engineering support during such emergencies. A USACE team was assessing the situation in New Orleans on the 29th, water flow was stopped September 2nd, and the breach was closed on September 5th.

The US Secret Service has released the first photos Wednesday of the new presidential limousine that will transport Barack Obama down Pennsylvania Avenue next Tuesday as part of the 56th Presidential inaugural parade after he is sworn in at the Capitol. The First Limo – the 2009 Cadillac Presidential Limousine – will replace President Bush’s Cadillac DTS Presidential Limousine that rolled out in 2004.

Nicknamed “The Beast”, the hulking machine is a new model year 2009, modified limousine. According to General Motors, the new “2009 Cadillac Presidential Limousine” is the first not to carry a specific model name. The Obama Mobile was introduced on January 14 with noticeably different styling borrowed from the Cadillac Escalade and STS, while the suspension is most likely related to the Chevrolet Kodiak medium-duty truck.

Mr. David Caldwell of General Motors has revealed that the sleek black car would include a hand-crafted interior and “state of the art electronics.” The car’s high-tech security features include five-inch-thick (12.7-centimeter-thick) bombproof glass, tough-as-nails tires, and a sealed interior that’s invulnerable to chemical attack. The armoured limousine has been heavily modified to withstand potential attacks by weapons or bombs. The San Francisco Chronicle puts it in a proper perspective noting, “a half-inch of transparent armor is enough to stop a .44 Magnum round at point-blank range; at a thickness of 1 1/4 to 1 1/2 inches, the same material can withstand higher-velocity bullets fired from military assault rifles.”

According to spy photographer, Brenda Priddy, and General Motors, the limousine, which has the intricate, dual-textured grille, is also equipped with standard Goodyear Regional RHS truck tires in a 285/70R19.5 size, on 19.5-inch wheels. The rims have a run-flat device (manufactured by Hutchinson Industries). Xenon headlights from the Escalade are installed in the front, while the rear has some STS part. The doors are at least 20 centimeters (8 inches) thick. It carries the US flag on the front fenders and an embroidered Seal of the President of the United States is affixed to several panels in the back.

According to the US Secret Service, the vehicle would be a “valuable asset” in providing the President with the highest level of protection. “Although many of the vehicle’s security enhancements cannot be discussed, it is safe to say that this car’s security and coded communications systems make it the most technologically advanced protection vehicle in the world,” Nicholas Trotta, Assistant Director for the Office of Protective Operations said in a statement. The new limousine is the responsibility of White House Transportation Agency.

The Presidential State Car is the official state car used by the President of the United States. It is informally known as “Cadillac One”. The current Presidential State Car is a 2005 hand-crafted, armored, and stretched DTS (DeVille Touring Sedan) built on a GM four-wheel drive platform. It was first used on the second inauguration parade of George W. Bush in 2005. But the version to be used by President Obama uses a GMC Topkick chassis, while maintaining the Cadillac exterior.

The President of the United States travels in one of two armoured Cadillac limousines based upon the normal sedan, the Cadillac DTS, with heavy customisation. Lincoln cars have also been used in the past, most notably by President John F Kennedy. The current limousines were custom-built by O’Gara, Hess and Eisenhart, founded in Fairfield, Ohio in 1942. It specializes in armouring limousines for presidents and heads of state.

President William McKinley was the first US president to ride in an automobile. However, it was President Theodore Roosevelt who rode on the first government-owned car, a white Stanley Steamer. Roosevelt’s successor, William Howard Taft, was the first president to use a presidential state car that was permanently stored in the White House garage.

Meanwhile, Obama’s 2005 Chrysler 300C Hemi was auctioned on eBay with a starting bid of $100,000 and a buy-it-now price of $1,000,000. It has less than 21,000 miles on it and is in like-new condition. He leased the car in 2004 and traded it for a Ford Escape Hybrid in 2007. The car was sold to Tim O’Boyle.

The Eastern Conference defeated their Western Conference counterparts at the 2008 National Basketball Association All-Star Game held at New Orleans Arena in New Orleans, Louisiana on Sunday. The final score was 134-128.

The East took an early 11 point lead in the first 5 minutes, due to an injured Kobe Bryant only playing 2 minutes before sitting on the bench for the rest of the game. “There’s one player we really, really missed, and that was Kobe,” said West coach Byron Scott. The West later reduced the lead to 2 points, but at halftime, the East led 74-65.

The West trailed by 13 at the beginning of the fourth quarter, but rallied behind New Orleans point guard Chris Paul, who had seven assists in the final period. With 2:48 remaining, Brandon Roy scored a layup on an assist from Paul, giving the West a 122-119 lead, their biggest lead of the game.

The East then answered back with two three-pointers from Ray Allen, before Chris Paul tied the game with a three-pointer of his own. However, the East would then take the lead and the game with layups from Dwyane Wade and Allen, as well as a driving dunk from LeBron James. A Brandon Roy three-pointer put the game within three points with 8.7 seconds left, but 3 free throws from Ray Allen sealed the win for the East.

“The fourth quarter was crazy,” said Chris Paul. “We were down 13. We picked up the intensity. We took the lead a few times but Ray Allen was unbelievable the way he shot the ball. And that last dunk by LeBron, we had two people on him but that still wasn’t enough.”

With 27 points, 8 rebounds, and 9 assists, James was named the All-Star Game’s Most Valuable Player for the second time in his career. Some television commentators also considered Ray Allen a likely choice for the award, with 14 of his 28 points coming in the final 3 minutes of the game. “I think Ray Allen had a heck of a shooting night,” James said after being presented the award.

SpaceX called off the much-delayed inaugural launch of their new Falcon 1 rocket on Saturday from Kwajalein’s Omelek Island launch site. The intent was to launch the U.S. Air Force Academy’s FalconSat 2 satellite, which will monitor plasma interactions with the Earth’s upper atmosphere and magnetosphere.

The launch was delayed, then finally cancelled after an oxygen boil-off vent had accidentally been left open. The oxygen was unable to cool the helium pressurant, which then proceeded to evaporate faster than it could be replenished. A main computer issue, probably serious enough to cause a scrub on its own, was also discovered.

This long-anticipated flight was originally expected to be launched in January 2005, however a series of setbacks forced a series of delays, with the flight most recently scheduled to be in early 2006. It was intended to be launched from the Kwajalein atoll in the middle of the Pacific Ocean.

The maiden voyage was originally intended to launch from Vandenberg Air Force Base in California with a Naval Research Laboratory satellite and a Space Services Incorporated space burial payload.

Junior Senator of New York and former United States 2008 presidential candidate Hillary Rodham Clinton attended a ceremony marking the grand opening of the Erie Canal Harbor in Buffalo, New York. This marks the first time in nearly 100 years that the inner harbor of Buffalo’s Canal waterfront has seen significant development, dedicated to tourism and the people.

“Hello Buffalo!” stated an enthusiastic Clinton to a crowd of 500 people. “It is such a privilege and joy to see this project and all that it means not only for Buffalo, but Western New York. This truly has been a labor of love. All of the people before you, plus so many others have seen this vision and have been committed to making it a reality.”

“In a few minutes [I will] walk to the center of the Whipple Truss bridge and reenact that famous ceremony that took place 183 years ago,” added Clinton. “[The original development] took so many immigrant workers and so many leaders who never ever wavered. Local economies boomed, commerce exploded and this (the Canal) became one of the greatest infrastructure achievements in the history of the world,” Clinton added.

In 1825, then state governor DeWitt Clinton dedicated the canal to the city in almost the same spot where Clinton stood. He traveled the entire route of the Canal, bringing water from each stop. In a ceremony, the water was dumped from buckets off the truss bridge, something Clinton and other politicians reenacted today. Off to her right, the Buffalo Fire Department sprayed water into the harbor from a fire fighting boat, just as it did over 100 years ago. Cannons were also fired into the air just like they were when governor Clinton celebrated building of the Canal.

“I am very proud to support the redevelopment of the Erie Canal Harbor. The progress we are celebrating today, will continue. I am as convinced as can be, that as we see progress here at the inner harbor and the outer harbor, we are going to see the revival of Buffalo continue,” said Clinton.

The project cost almost US$55 million to build, and its not over yet. A stretch of lakeside parks, trails and mixed use commercial and residential development is also planned for Buffalo’s waterfront. City mayor Byron Brown says the redevelopment will attract hundreds of millions of dollars in new projects.

Several other politicians were also present such as Senior N.Y Senator Charles Schumer, former Buffalo mayor Anthony Masiello and congressman Brian Higgins.

“By reclaiming our past, we are forging our future. The Erie Canal project is an economic shot in the arm for Buffalo and Western New York that will spur business, jobs and tourism,” stated Schumer.

Wednesday, April 29, 2009THEMIS space probes discovered that the Northern lights are seen when electrical tornadoes, rotating faster than a million miles an hour, hover about 40,000 miles (60,000 km) above the earth. The energy spins down to the Earth’s ionosphere where the tornadoes become unstable, and interact with the Earth’s magnetic field.

Professor Karl-Heinz Glassmeier, director of the Institute for Geophysics and Extraterrestrial Physics in Braunschweig Germany, explains, “When these space tornadoes reach the upper atmosphere their enormous energy heats the air so strongly it starts glowing. That is what generates the aurorae.”

“It is here that all the energy is released, forming the aurorae. What we see as beautiful lights and colors are actually the product of a violent electrical storm in space. While these electrical discharges do not cause any direct harm to humans, they can damage man-made structures such as power transformers and communications systems,” said Andreas Keiling, a physicist at the University of California at Berkeley.

Time History of Events and Macroscale Interactions during Substorms (THEMIS) are five probes launched by NASA in February 2007, which orbited Earth recording the volume and electrical current which was higher than 100,000 amperes.

Scientists had previously concluded that aurorae are caused by electrically charged particles discharged as solar winds from the sun which interact with the Earth’s magnetic field. However, these solar discharges strike the Earth where the sun is shining and the aurorae occur in the opposite hemisphere and are visible in the night sky.

This anomaly was cleared up by THEMIS satellites which showed that the Earth’s magnetic field held the charged particles before deflecting them from the day side of the planet across to the opposite side of the planet where the particles massed into huge clouds. There the accumulated charge expands continuously until finally the cloud becomes unstable releasing its energy as a geomagnetic tornado which travels down towards the earth along magnetic field lines becoming visible as aurorae in the sky.

The scientists presented their findings at the European Geosciences Union (EGU) in Vienna, Austria just this week.
