Слайд 2These clock tower of the Parliament of the United Kingdom is
heard all over the world. Microphones radio services the BBC transmit their fight every hour. With the first stroke of big Ben in the night of 31 to 1 planet officially under international interim standard goes into the New Year.
Слайд 3The big Ben bell tower in London, part of the architectural
complex of Westminster Palace. The official name of big Ben “Clock tower of Westminster Palace”, also referred to as the “Tower of St. Stephen”
Слайд 4The clock tower rises 98 metres above the river Thames. Mounted
on a tower clock mechanism, characterized by high accuracy. We can say that this is the “main clock” of the state. Huge, specially cast for the bell tower “big Ben”, weighing 13,5 tons, strikes the hours. Fight the Big Ben British continuously transmit radio. During the parliamentary session, after dark, the tower turns a spotlight.
Слайд 5In big Ben tourists are not allowed. To get to the
top of 96 meter tower can only by a narrow spiral staircase. 334 steps lead to small open area in the center of which is the legendary bell which gave the name to the Clock tower. His height of over 2 meters and a diameter of nearly 3 meters.
Слайд 6Big Ben and its surrounding other small bells ringing knock out
the following words: “Through this hour the Lord keeps me, and his strength will not allow anyone to stumble”. When the chimes strike the first blow of the hammer on big Ben exactly coincides with the first seconds of the hour. Every 2 days the mechanism undergoes thorough inspection and lubrication, counted daily temperature and pressure. But, as any clock mechanism, the clock tower of the British Parliament sometimes late or in a hurry. I must say that the error is not large, just 1.5 — 2 seconds. To remedy the situation all you need is a coin, old English penny. No one really knows who first came up with the idea to use coins, but the idea worked. Old English penny placed on the pendulum 4 meters long accelerates its motion for 2.5 seconds per day. Adding or removing a penny Keeper thus achieves accuracy. The mechanism, despite its almost 1.5 century history and weight 5 tons, works perfectly.
Слайд 7The dials of big Ben look at all 4 sides of
the world. They are made from opal Birmingham, the hands of the clock made of cast iron, and minute made of copper sheet. It is estimated that the minute hands are for the year the total distance of 190 km.
Слайд 8Big Ben is a symbol of its time, the period of
greatest dawn of the country. And the inscription in Latin at the base of each of the four dials: “Domine Salvam fac Reginam nostram Victoriam primam” (“God save Queen Victoria!”) — a tribute of personal respect for the monarch, and in which there was such a thing as the British Empire. Around the perimeter of the tower on the right and left of the clock is inscribed with one phrase in Latin: “Laus Deo” (“praise the Lord” or “Thank God”)
Слайд 9Charles Berry, the architect who built the Palace of Westminster, in
1844, requested the Parliament to grant the construction hours on the tower of St. Stephen. To build a watch mechanic took Benjamin by Valami. It was agreed that a new clock will be the largest and finest in the world, and their bell — the most difficult one to call him was heard if not the entire Empire, then, at least, throughout its capital.
Слайд 10When the project was completed hours, between its author and the
authorities began arguing about the accuracy of the hours. The astronomer Royal, Professor George airy insisted that the first stroke of the bell every hour was performed with an accuracy of one second. The accuracy was checked every hour by Telegraph, connecting big Ben to Greenwich mean Observatory.
Слайд 11Valami told that for hours, open to the winds and weather,
such precision, and that generally it is useless. Five years of this dispute, and eiri won. The project Valami was rejected. Clock with the required accuracy have been made a certain dent. They weighed five tons.
Слайд 12Then began the considerable efforts on the casting of the bell
and the debate in Parliament on this issue. It was at this time and include the version of the origin of the name big Ben. The official version: bell is named in honor of the chief of construction works sir Benjamin Hall. For its impressive size foreman gave the nickname Big Ben. According to another, unofficial version, the bell was named after the famous strongman and boxer since the times of Queen Victoria Benjamin count.
Слайд 13When the clock and bell have already been brought up and
mounted, it became clear that iron arrows are too heavy and filling of a light alloy. The clock tower were set in motion may 21, 1859. Until 1912 the clock was lit by gas jets, which were later replaced with electric lamps. And on the radio for the first time the chimes sounded on 31 December 1923.
Слайд 14After big Ben during the second world war a bomb fell,
the clock started to go not so sure.
Слайд 15These watches has received huge popularity both in England and abroad.
In London there was a lot of “Little Bens”, reduced copies of the tower of St. Stephen's Cathedral with a clock on top. Such towers — something between an architectural structure and outdoor living rooms for hours — began to build almost all intersections. The most famous “Little Ben” is near the railway station Victoria, but in fact in almost every area of London you can find little Ben)
