Shimla, Himachal Pradesh, India

Shimla, also known as Simla, is the capital and largest city of the northern Indian state of Himachal Pradesh. Shimla is also a district which is bounded by Mandi and Kullu in the north, Kinnaur in the east, the state of Uttarakhand in the south-east, and Solan and Sirmaur. In 1864, Shimla was declared as the summer capital of British India, succeeding Murree, northeast of Rawalpindi. After independence, the city became the capital of Punjab and was later named the capital of Himachal Pradesh. It is the principal commercial, cultural and educational centre of the hilly regions of the state. As of 2011, the city had 171,817 permanent residents, and was one of the least populous capital cities in India.

Small hamlets were recorded prior to 1815 when the English forces took control of the area. The climatic conditions attracted the British to establish the city in the dense forests of Himalayas. As the summer capital, Shimla hosted many important political meetings including the Simla Accord of 1914 and the Simla Conference of 1945. After independence, the state of Himachal Pradesh came into being in 1948 as a result of integration of 28 princely states. Even after independence, the city remained an important political centre, hosting the Simla Agreement of 1972. After the reorganisation, the Mahasu district and its major portion were merged with Shimla. Its name is derived from the goddess Shyamala Devi, an incarnation of the Hindu goddess Kali[citation needed]. As of 2011 Shimla comprises 19 hill states, namely Baghal, Baghat, Balsan, Bashahr, Bhajji, Bija, Darkoti, Dhami, Jubbal, Keonthal, Kumharsain, Kunihar, Kuthar, Mahlog, Mangal, Nalagarh (Hindur), Sangri and Tharoch.

Shimla is home to a number of buildings that are styled in the Tudorbethan and neo-Gothic architectures dating from the colonial era, as well as multiple temples and churches. The colonial architecture and churches, the temples and the natural beauty of the city attract a large number of tourists. The major attractions include the Viceroy Lodge, the Christ Church, the Jakhoo Temple, the Mall Road and the Ridge, which together form the city centre. The Kalka–Shimla Railway line built by the British, a UNESCO World Heritage Site, is also a major tourist attraction. Owing to its steep terrain, Shimla hosts the mountain biking race MTB Himalaya, which started in 2005 and is regarded as the biggest event of its kind in South Asia. Shimla also has the largest natural ice skating rink in South Asia. The ice skating season usually begins in the start of December and goes on till the end of February. Apart from being a tourism centre, the city is also an educational hub with a number of colleges and research institutions. The city also has sporting venues like the Indira Gandhi Rajya Khel Parisar, the main sports complex and the Naldehra Golf Club.

The vast majority of the area occupied by the present-day Shimla city was dense forest during the 18th century. The only civilisation consisted of the Jakhoo temple and a few scattered houses. The area was called 'Shimla', named after a Hindu goddess, Shyamala Devi, an incarnation of Kali.

The area of present-day Shimla was invaded and captured by Bhimsen Thapa of Nepal in 1806. The British East India Company took control of the territory as per the Sugauli Treaty after the Anglo-Nepalese War (1814–16). The Gurkha leaders were quelled by storming the fort of Malaun under the command of David Ochterlony in May 1815. In a diary entry dated 30 August 1817, the Gerard brothers, who surveyed the area, describe Shimla as "a middling-sized village where a fakir is situated to give water to the travellers". In 1819, Lieutenant Ross, the Assistant Political Agent in the Hill States, set up a wood cottage in Shimla. Three years later, his successor and the Scottish civil servant Charles Pratt Kennedy built the first pucca house in the area in 1822, near what is now the Himachal Pradesh Legislative Assembly building. The accounts of the Britain-like climate started attracting several British officers to the area during the hot Indian summers. By 1826, some officers had started spending their entire vacation in Shimla. In 1827, Lord Amherst, the Governor-General of Bengal, visited Shimla and stayed in the Kennedy House. A year later, Lord Combermere, the Commander-in-Chief of the British forces in India, stayed at the same residence. During his stay, a three-mile road and a bridge were constructed near Jakhu. In 1830, the British acquired the surrounding land from the chiefs of Keonthal and Patiala in exchange for the Rawin pargana and a portion of the Bharauli pargana. The settlement grew rapidly after this, from 30 houses in 1830 to 1,141 houses in 1881.

Combermere's successor Earl Dalhousie visited Shimla in the same year. After this, the town saw regular visits from the Governors General and Commanders-in-Chief of British India. A number of young British officers started visiting the area to socialise with the higher-ups; they were followed by ladies looking for marriage alliances for their relatives. Shimla thus became a hill station famous for balls, parties and other festivities. Subsequently, residential schools for pupils from upper-class families were established nearby. By the late 1830s, the city also became a centre for theatre and art exhibitions. As the population increased, a number of bungalows were built and a big bazaar was established in the town. The Indian businessmen, mainly from Sood and Parsi communities, arrived in the area to cater to the needs of the growing European population. On 9 September 1844 the foundation of the Christ Church was laid. Subsequently, several roads were widened and the construction of the Hindustan-Tibet road with a 560-feet tunnel was taken up in 1851–52. This tunnel, now known as the Dhalli Tunnel, was started by a Major Briggs in 1850 and completed in the winter of 1851–52. The 1857 uprising caused a panic among the European residents of the town, but Shimla remained largely unaffected by the rebellion.

In 1863, the Viceroy of India, John Lawrence, decided to shift the summer capital of the British Raj to Shimla. He took the trouble of moving the administration twice a year between Calcutta and this separate centre over 1,000 miles away, despite the fact that it was difficult to reach. Lord Lytton (Viceroy of India 1876–1880) made efforts to plan the town from 1876, when he first stayed in a rented house, but began plans for a Viceregal Lodge, later built on Observatory Hill. A fire cleared much of the area where the native Indian population lived (the "Upper Bazaar" nowadays known as the Ridge), and the planning of the eastern end to become the centre of the European town forced them to live in the Middle and Lower Bazaars on the lower terraces descending the steep slopes from the Ridge. The Upper Bazaar was cleared for a town hall, with many facilities such as library and theatre, as well as offices for police and military volunteers as well as municipal administration.

During the "Hot Weather", Shimla was also the Headquarters of the Commander-in-Chief, India, the head of the Indian Army, and many Departments of the Government. The summer capital of the regional Government of the Punjab moved from Murree, in modern-day Pakistan, to Shimla in 1876. They were joined by many of the British wives and daughters of the men who remained on the plains. Together these formed Shimla Society, which, according to Charles Allen, "was as close as British India ever came to having an upper crust." This may have been helped by the fact that it was very expensive, having an ideal climate and thus being desirable, as well as having limited accommodation. British soldiers, merchants and civil servants moved here each year to escape from the heat during summer in the Indo-Gangetic plain. The presence of many bachelors and unattached men, as well as the many women passing the hot weather there, gave Shimla a reputation for adultery, and at least gossip about adultery: as Rudyard Kipling said in a letter cited by Allen, it had a reputation for "frivolity, gossip and intrigue".

Statue of Liberty (Colossal Neoclassical Sculpture), Liberty Island, New York

The Statue of Liberty is a colossal neoclassical sculpture on Liberty Island in New York Harbor in New York City, in the United States. The copper statue, a gift from the people of France to the people of the United States, was designed by French sculptor Frédéric Auguste Bartholdi and built by Gustave Eiffel. The statue was dedicated on October 28, 1886.

The Statue of Liberty is a robed female figure representing Libertas, the Roman goddess. She holds a torch above her head, and in her left arm carries a tabula ansata (a tablet evoking the law) inscribed "July 4, 1776", the date of the American Declaration of Independence. A broken chain lies at her feet. The statue became an icon of freedom and of the United States, and was a welcoming sight to immigrants arriving from abroad.

Bartholdi was inspired by French law professor and politician Édouard René de Laboulaye, who is said to have commented in 1865 that any monument raised to American independence would properly be a joint project of the French and American peoples. Due to the post-war instability in France, work on the statue did not commence until the early 1870s. In 1875, Laboulaye proposed that the French finance the statue and the Americans would provide the site and build the pedestal. Bartholdi completed the head and the torch-bearing arm before the statue was fully designed, and these pieces were exhibited for publicity at international expositions.

The torch-bearing arm was displayed at the Centennial Exposition in Philadelphia in 1876, and in Madison Square Park in Manhattan from 1876 to 1882. Fundraising proved difficult, especially for the Americans, and by 1885 work on the pedestal was threatened due to lack of funds. Publisher Joseph Pulitzer of the New York World started a drive for donations to complete the project that attracted more than 120,000 contributors, most of whom gave less than a dollar. The statue was constructed in France, shipped overseas in crates, and assembled on the completed pedestal on what was then called Bedloe's Island. The statue's completion was marked by New York's first ticker-tape parade and a dedication ceremony presided over by President Grover Cleveland.

The statue was administered by the United States Lighthouse Board until 1901 and then by the Department of War; since 1933 it has been maintained by the National Park Service. Public access to the balcony surrounding the torch has been barred for safety reasons since 1916.

According to the National Park Service, the idea for the Statue of Liberty was first proposed by Édouard René de Laboulaye the president of the French Anti-Slavery Society and a prominent and important political thinker of his time. The project is traced to a mid-1865 conversation between Édouard René de Laboulaye, a staunch abolitionist and Frédéric Bartholdi, a sculptor. In after-dinner conversation at his home near Versailles, Laboulaye, an ardent supporter of the Union in the American Civil War, is supposed to have said: "If a monument should rise in the United States, as a memorial to their independence, I should think it only natural if it were built by united effort—a common work of both our nations." The National Park Service, in a 2000 report, however, deemed this a legend traced to an 1885 fundraising pamphlet, and that the statue was most likely conceived in 1870. In another essay on their website, the Park Service suggested that Laboulaye was minded to honor the Union victory and its consequences, "With the abolition of slavery and the Union's victory in the Civil War in 1865, Laboulaye's wishes of freedom and democracy were turning into a reality in the United States. In order to honor these achievements, Laboulaye proposed that a gift be built for the United States on behalf of France. Laboulaye hoped that by calling attention to the recent achievements of the United States, the French people would be inspired to call for their own democracy in the face of a repressive monarchy."
Bartholdi's design patent

According to sculptor Frédéric Auguste Bartholdi, who later recounted the story, Laboulaye's comment was not intended as a proposal, but it inspired Bartholdi. Given the repressive nature of the regime of Napoleon III, Bartholdi took no immediate action on the idea except to discuss it with Laboulaye. Bartholdi was in any event busy with other possible projects; in the late 1860s, he approached Isma'il Pasha, Khedive of Egypt, a plan to build "Progress" or "Egypt Carrying the Light to Asia", a huge lighthouse in the form of an ancient Egyptian female fellah or peasant, robed and holding a torch aloft, at the northern entrance to the Suez Canal in Port Said. Sketches and models were made of the proposed work, though it was never erected. There was a classical precedent for the Suez proposal, the Colossus of Rhodes: an ancient bronze statue of the Greek god of the sun, Helios. This statue is believed to have been over 100 feet (30 m) high, and it similarly stood at a harbor entrance and carried a light to guide ships.

Any large project was further delayed by the Franco-Prussian War, in which Bartholdi served as a major of militia. In the war, Napoleon III was captured and deposed. Bartholdi's home province of Alsace was lost to the Prussians, and a more liberal republic was installed in France.  As Bartholdi had been planning a trip to the United States, he and Laboulaye decided the time was right to discuss the idea with influential Americans. In June 1871, Bartholdi crossed the Atlantic, with letters of introduction signed by Laboulaye.

Arriving at New York Harbor, Bartholdi focused on Bedloe's Island (now named Liberty Island) as a site for the statue, struck by the fact that vessels arriving in New York had to sail past it. He was delighted to learn that the island was owned by the United States government—it had been ceded by the New York State Legislature in 1800 for harbor defense. It was thus, as he put it in a letter to Laboulaye: "land common to all the states." As well as meeting many influential New Yorkers, Bartholdi visited President Ulysses S. Grant, who assured him that it would not be difficult to obtain the site for the statue. Bartholdi crossed the United States twice by rail, and met many Americans who he thought would be sympathetic to the project. But he remained concerned that popular opinion on both sides of the Atlantic was insufficiently supportive of the proposal, and he and Laboulaye decided to wait before mounting a public campaign.
Bartholdi's Lion of Belfort

Bartholdi had made a first model of his concept in 1870. The son of a friend of Bartholdi's, American artist John LaFarge, later maintained that Bartholdi made the first sketches for the statue during his U.S. visit at La Farge's Rhode Island studio. Bartholdi continued to develop the concept following his return to France. He also worked on a number of sculptures designed to bolster French patriotism after the defeat by the Prussians. One of these was the Lion of Belfort, a monumental sculpture carved in sandstone below the fortress of Belfort, which during the war had resisted a Prussian siege for over three months. The defiant lion, 73 feet (22 m) long and half that in height, displays an emotional quality characteristic of Romanticism, which Bartholdi would later bring to the Statue of Liberty

Antarctica (Most Coldest Place on Earth), Earth's Southernmost Continent

Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometers (5,400,000 square miles), it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is a desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland. The temperature in Antarctica has reached −89.2 °C (−128.6 °F), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra.

Although myths and speculation about a Terra Australis ("Southern Land") date back to antiquity, Antarctica is noted as the last region on Earth in recorded history to be discovered and colonized by humans, being only first sighted in 1820 by the Russian expedition of Fabian Gottlieb von Bellingshausen and Mikhail Lazarev on Vostok and Mirny, who sighted the Fimbul ice shelf. The continent, however, remained largely neglected for the rest of the 19th century because of its hostile environment, lack of easily accessible resources, and isolation. In 1895, the first confirmed landing was conducted by a team of Norwegians.

Antarctica is a de facto condominium, governed by parties to the Antarctic Treaty System that have consulting status. Twelve countries signed the Antarctic Treaty in 1959, and thirty-eight have signed it since then. The treaty prohibits military activities and mineral mining, prohibits nuclear explosions and nuclear waste disposal, supports scientific research, and protects the continent's ecozone. Ongoing experiments are conducted by more than 4,000 scientists from many nations.

Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. There are a number of rivers and lakes in Antarctica, the longest river being the Onyx. The largest lake, Vostok, is one of the largest sub-glacial lakes in the world. Antarctica covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations

Antarctica is divided in two by the Transantarctic Mountains close to the neck between the Ross Sea and the Weddell Sea. The portion west of the Weddell Sea and east of the Ross Sea is called West Antarctica and the remainder East Antarctica, because they roughly correspond to the Western and Eastern Hemispheres relative to the Greenwich meridian.

About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft). In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape.

West Antarctica is covered by the West Antarctic Ice Sheet. The sheet has been of recent concern because of the real, if small, possibility of its collapse. If the sheet were to break down, ocean levels would rise by several metres in a relatively geologically short period of time, perhaps a matter of centuries. Several Antarctic ice streams, which account for about 10% of the ice sheet, flow to one of the many Antarctic ice shelves: see ice-sheet dynamics.

East Antarctica lies on the Indian Ocean side of the Transantarctic Mountains and comprises Coats Land, Queen Maud Land, Enderby Land, Mac. Robertson Land, Wilkes Land, and Victoria Land. All but a small portion of this region lies within the Eastern Hemisphere. East Antarctica is largely covered by the East Antarctic Ice Sheet.
Mount Erebus, an active volcano on Ross Island

Vinson Massif, the highest peak in Antarctica at 4,892 m (16,050 ft), is located in the Ellsworth Mountains. Antarctica contains many other mountains, on both the main continent and the surrounding islands. Mount Erebus on Ross Island is the world's southernmost active volcano. Another well-known volcano is found on Deception Island, which is famous for a giant eruption in 1970. Minor eruptions are frequent and lava flow has been observed in recent years. Other dormant volcanoes may potentially be active. In 2004, a potentially active underwater volcano was found in the Antarctic Peninsula by American and Canadian researchers.

Antarctica is home to more than 70 lakes that lie at the base of the continental ice sheet. Lake Vostok, discovered beneath Russia's Vostok Station in 1996, is the largest of these subglacial lakes. It was once believed that the lake had been sealed off for 500,000 to one million years but a recent survey suggests that, every so often, there are large flows of water from one lake to another.

There is some evidence, in the form of ice cores drilled to about 400 m (1,300 ft) above the water line, that Lake Vostok's waters may contain microbial life. The frozen surface of the lake shares similarities with Jupiter's moon, Europa. If life is discovered in Lake Vostok, it would strengthen the argument for the possibility of life on Europa. On 7 February 2008, a NASA team embarked on a mission to Lake Untersee, searching for extremophiles in its highly alkaline waters. If found, these resilient creatures could further bolster the argument for extraterrestrial life in extremely cold, methane-rich environments.

Several governments maintain permanent manned research stations on the continent. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. An Orthodox church—Trinity Church, opened in 2004 at the Russian Bellingshausen Station—is manned year-round by one or two priests, who are similarly rotated every year.
Port Lockroy Museum

The first semi-permanent inhabitants of regions near Antarctica (areas situated south of the Antarctic Convergence) were British and American sealers who used to spend a year or more on South Georgia, from 1786 onward. During the whaling era, which lasted until 1966, the population of that island varied from over 1,000 in the summer (over 2,000 in some years) to some 200 in the winter. Most of the whalers were Norwegian, with an increasing proportion of Britons. The settlements included Grytviken, Leith Harbour, King Edward Point, Stromness, Husvik, Prince Olav Harbour, Ocean Harbour and Godthul. Managers and other senior officers of the whaling stations often lived together with their families. Among them was the founder of Grytviken, Captain Carl Anton Larsen, a prominent Norwegian whaler and explorer who, along with his family, adopted British citizenship in 1910.

The first child born in the southern polar region was Norwegian girl Solveig Gunbjørg Jacobsen, born in Grytviken on 8 October 1913, and her birth was registered by the resident British Magistrate of South Georgia. She was a daughter of Fridthjof Jacobsen, the assistant manager of the whaling station, and Klara Olette Jacobsen. Jacobsen arrived on the island in 1904 and became the manager of Grytviken, serving from 1914 to 1921; two of his children were born on the island.

Emilio Marcos Palma was the first person born south of the 60th parallel south (the continental limit according to the Antarctic Treaty), as well as the first one born on the Antarctic mainland, in 1978 at Base Esperanza, on the tip of the Antarctic Peninsula; his parents were sent there along with seven other families by the Argentine government to determine if the continent was suitable for family life. In 1984, Juan Pablo Camacho was born at the Frei Montalva Station, becoming the first Chilean born in Antarctica. Several bases are now home to families with children attending schools at the station. As of 2009, eleven children were born in Antarctica (south of the 60th parallel south): eight at the Argentine Esperanza Base and three at the Chilean Frei Montalva Station.

Leaning Tower of Pisa (Freestanding Bell Tower), Piazza del Duomo, 56126 Pisa PI, Italy

The Leaning Tower of Pisa  is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa, known worldwide for its unintended tilt.

It is situated behind Pisa's cathedral and is the third oldest structure in the city's Cathedral Square (Piazza del Duomo), after the cathedral and the Pisa Baptistry. The tower's tilt began during construction, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt increased in the decades before the structure was completed and gradually increased until the structure was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries.

The height of the tower is 55.86 meters (183.27 feet) from the ground on the low side and 56.67 meters (185.93 feet) on the high side. The width of the walls at the base is 2.44 m (8 ft 0.06 in). Its weight is estimated at 14,500 metric tons (16,000 short tons). The tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. Prior to restoration work performed between 1990 and 2001, the tower leaned at an angle of 5.5 degrees, but the tower now leans at about 3.99 degrees. This means the top of the tower is displaced horizontally 3.9 meters (12 ft 10 in) from the center.

Construction of the tower occurred in three stages over 199 years. Work on the ground floor of the white marble campanile began on August 14, 1173 during a period of military success and prosperity. This ground floor is a blind arcade articulated by engaged columns with classical Corinthian capitals.

The tower began to sink after construction had progressed to the second floor in 1178. This was due to a mere three-metre foundation, set in weak, unstable subsoil, a design that was flawed from the beginning. Construction was subsequently halted for almost a century, because the Republic of Pisa was almost continually engaged in battles with Genoa, Lucca, and Florence. This allowed time for the underlying soil to settle. Otherwise, the tower would almost certainly have toppled. In 1198, clocks were temporarily installed on the third floor of the unfinished construction.

In 1272, construction resumed under Giovanni di Simone, architect of the Camposanto. In an effort to compensate for the tilt, the engineers built upper floors with one side taller than the other. Because of this, the tower is actually curved. Construction was halted again in 1284 when the Pisans were defeated by the Genoans in the Battle of Meloria.

The seventh floor was completed in 1319. The bell-chamber was finally added in 1372. It was built by Tommaso di Andrea Pisano, who succeeded in harmonizing the Gothic elements of the bell-chamber with the Romanesque style of the tower. There are seven bells, one for each note of the musical major scale. The largest one was installed in 1655.

After a phase (1990–2001) of structural strengthening, the tower is currently undergoing gradual surface restoration, in order to repair visible damage, mostly corrosion and blackening. These are particularly pronounced due to the tower's age and its exposure to wind and rain.
