Petronas Towers

The Petrones Towers in Kuala Lumpur, Malaysia, are the second talzest buildings of the world. The towers are also known as the Petrona Twin Towers. Petronas is short for Petroliam Nasional Bhd. Malaysia's national petroleum corporation. The twin towers were built to house the headquarters of Petronas. The towers have shopping and entertainment facilities, a petroleum museum, a symphony hall,a mosque. and a multimedia conference centre.
The towers are set in the heart of the city. Both the towers have 88 storeys that rise to a height of 378 m. The total height at the towers is 452 m and they cover an area of 4,27,353 sq m. The towers are jioined by a flexible sky bridge on the 41st and 42nd floors. The towers were considered the tallest buildings in the world by the Council on Tall Buildings and Urban Habitat until the completion of Taipei 101.



Architect and architecture


The Petronas Towers were designed by Pelli Clarke Pelli Architects (formerly known as Cesar Pelli and Associates). The towers have a simple geometric form that is common in Muslim architecture. The exterior of the towers has two interlocking squares that
form an eight-pointed star. Eight semi-circles are placed upon the eight-pointed stars to . soften the inner angles. The circular pattern of the buildings rise and gradually taper at I the upper levels. The exterior of the towers is organised in horizontal ribbons of Vision glass and stainless steel which glint and shimmer in the sun. The interior of the towers shows the beauty and tradition of Malaysian arts and handicrafts.


Pinnacles


The peaks or top of the Petronas Towers are made of structural steel. The pinnacles of the towers are 73.5 m tall. One pinnacle was fabricated in Japan and the other was made in Korea. Each pinnacle has a spire,mi1st ball, and ring ball.



Sky bridge


The sky bridge on the 4lst and 42nd floors that connects the two towers was constructed to ease travel between the towers. It is a double-decked sky bridge and it can also function as an escape route in an emergency. The bridge is supported by a three-hinged arch, which consists of giant round bearings at the base. It has a pair of cylindrical legs that IS 51 m long. The legs are locked to a box girder below the centre of the bridge.

Elevator system


The Petronas Towers are equipped with 29 double-decker, high-speed passenger lifts. There are four executive lifts and six heavy-duty service lifts in each tower. The elevators are designed to serve every door of the tower. The lifts can transport passengers from the basement car parking to the top of the towers.


Foundation and inauguration


The construction of the Petronas towers was completed in many phases. The plan for constructing the towers began January 1992. The foundation work of the towers started in March 1992. The towers were inaugurated by Dato Seri Dr Mahathir bin Mohamad, the 4th prime minister of Malaysia, on 31 August 1999.

The first recorded  thermometer  was produced by the Italian, Santorio Santorio (1561-1636) who was one of a group of Venetian scientists working at the end of the Sixteenth Century. As with many inventions the thermometer came about through the work of many scientists and was improved upon by many others. 1596  Galileo Galilei and the first thermoscope Galileo Galilei is often claimed to be the inventor of the thermometer. However the instrument he invented could not strictly be called a thermometer: to be a  thermometer  an instrument must  measure temperature differences; Galileo's instrument did not do this, but merely  indicated  temperature differences. His instrument should rightly be called a  thermoscope . The Thermoscope The predecessor to the thermometer, the thermoscope is a thermometer without a scale; it indicates differences in temperature only ie it can show if the temperature is higher, lower or the same, but unlike a thermometer it cannot measure

Microscope A microscope is an optical instrument that is used to view objects that are invisible to the naked eye.Microscope use a combination of the images of very small objects. The first microscope were known as 'flea glasses' as they were used to view fleas or tiny creeping things.These microscope were simple tubes with a plate  and a lens at the ends.they magnified the image to more than 10 times the actual size. The first microscope the art of grinding glasses and making spectacles was known to people since the 14th century.the first microscope was made by Hans and Zacharias Jansen of the Netherlands in 1590.Hans and Zacharias Jansen were lens maker they made a microscope by placing two lenses in a tube Microscopy Microscopy is the science of examining small objects using microscope.the three branches of microscopy are optical microscopy,electron microscopy and scanning probe microscopy.
