Group of dancers performed a traditional Maori dance battle - Haka, in honor of Prince William, who visited New Zealand as a representative of Buckingham Palace. I must say, such emotional dance is certainly better to see live, but photos aren’t bad themselves. Look.  In 1969, Chairman Mao ordered the construction of Beijing's underground city. It was designed for six million residents in case of a nuclear war. The war did not happen and the underground city is in ruins.  The Jin Mao Tower is an 88-storey landmark supertall skyscraper in Shanghai, China. It contains offices and the Shanghai Grand Hyatt hotel. The building employs an advanced structural engineering system of wind and earthquake engineering which fortify it against typhoon winds of up to 200 km/h (with the top swaying by a maximum of 75 cm) and earthquakes of up to 7 on the Richter scale. The steel shafts have shear joints that act as shock absorbers to cushion the lateral forces imposed by winds and quakes, and the swimming pool on the 57th floor is said to act as a passive damper.  |
