The Burj Khalifa, known as the Burj Dubai prior to its inauguration in 2010, is a skyscraper in Dubai, United Arab Emirates. With a total height of 829.8 m and a roof height of 828 m, the Burj Khalifa has been the tallest structure and building in the world since it’s topping out in 2009.

Height: 828 m, 830 m to tip CTBUH

Floors: 163

Top floor: 584.5 m (1,918 ft)

Owner: Emaar Properties

Architects: Adrian Smith, George J. Efstathiou, Marshall Strabala

Cost: 150 crores USD

The building was originally named Burj Dubai but was renamed in honour of the ruler of Abu Dhabi and president of the United Arab Emirates, Khalifa bin Zayed Al Nahyan; Abu Dhabi and the UAE government lent Dubai money to pay its debts.Four people died during the construction of BurjKhalifa.
The world's most-prestigious address is home to a select few. With 900 residences including studios, one-, two-, three- and four-bedroom suites, The Residences at Burj Khalifa are designed for the connoisseur. High living becomes a reality where the homes are located on levels 19 to 108 of Burj Khalifa.

Burj Khalifa's construction will have used 330,000 m3 (431,600 cu yd) of concrete and 39,000 tonnes (43,000 ST; 38,000 LT) of steel rebar, and construction will have taken 22 million man-hours. The exterior cladding of Burj Khalifa began in May 2007 and was completed in September 2009.

The opening ceremony included another surprise. The tower, which had been known as the Burj Dubai, was renamed the Burj Khalifa, in honour of Sheik Khalifa bin Zayed Al Nahyan, the president of the neighbouring emirate Abu Dhabi. The last-minute switch carries a symbolic weight in light of the billions of dollars oil-rich Abu Dhabi has poured into Dubai in order to cover its debts.

The Burj is not only the tallest building in the world, it’s also home to the highest observation deck, swimming pool, elevator, restaurant, and fountain in the world.

Speaking of the acrophobia inducing elevator, it travels at speeds roughly 40 miles per hour (65 kilometres per hour) and reaches the observation deck in about 2 minutes.

Once at the top, visitors can enjoy temperatures that are nearly 15 degrees cooler than at the building’s base.

Dubai is built in the middle of the desert, so to withstand the UAE’s 120-degree blistering summer heat the tower is covered with 24,348 cladding panels.

Many skyscrapers are built to bend with the wind—the Burj, which will be exposed to strong desert winds, more than others. According to lead architect George Efstathiou, “the building is tuned to sway slowly so your middle ear doesn’t pick it up,” Efstathiou explained. “They tune it just like a musical instrument so that the harmonics of the building don’t coincide with the harmonics caused by the wind…. We tune it so that on the floors where people are going to be, you don’t feel it that much”.

Before all those floors fill up with people, Burj Khalifa has an empty weight of 500,000 tons.

The building won’t be empty much longer, however. So if you want in, you better hurry; 90 percent of the 900 residences (not including the soon-to-open Giorgio Armani-designed hotel) have been sold.

The Smallest Computer In The World

          The Smallest Computer In The World The Smallest Computer in the World Fits On a Grain of Rice. Researchers at the University of Michigan just created the world's smallest computer (again). After all, it's unclear if the IBM computer even counts as an actual microcomputer. The IBM device lost all its programming and data as soon as it turns off, unlike the Michigan Micro Mote, which retained its programming even when it wasn’t externally powered. “It’s more of a matter of opinion whether they have the minimum functionality required,” said David Blaauw, a professor of electrical and computer engineering at University of Michigan who helped develop the University of Michigan's newest tiny device. If the IBM machine constituted a computer, then University of Michigan would work to gain back their title: their latest micro device measures 0.3mm per side (1/10th the size of IBM’s computer), and is smaller than a grain of rice. The de...
