Akbar

Akbar (14 October 1542 – 27 October 1605), known as Akbar the Great, was Mughal Emperor from 1556 until his death. He was the third and greatest ruler of the Mughal Dynasty in India. Akbar succeeded his father, Humayun, under a regent, Bairam Khan, who helped the young emperor expand and consolidate Mughal domains in India. A strong personality and a successful general, Akbar gradually enlarged the Mughal Empire to include nearly all of the Indian Subcontinent north of the Godavari river. His power and influence, however, extended over the entire country because of Mughal military, political, cultural, and economic dominance. To unify the vast Mughal state, Akbar established a centralised system of administration throughout his empire and adopted a policy of conciliating conquered rulers through marriage and diplomacy. In order to preserve peace and order in a religiously and culturally diverse empire, he adopted policies that won him the support of his non-Muslim subjects. Eschewing tribal bonds and Islamic state identity, Akbar strived to unite far-flung lands of his realm through loyalty, expressed through a Persianised culture, to himself as an emperor who had near-divine status.

Mughal India developed a strong and stable economy, leading to commercial expansion and greater patronage of culture. Akbar himself was a great patron of art and culture. He was fond of literature, and created a library of over 24,000 volumes written in Sanskrit, Hindustani, Persian, Greek, Latin, Arabic and Kashmiri, staffed by many scholars, translators, artists, calligraphers, scribes, bookbinders and readers. Holy men of many faiths, poets, architects and artisans adorned his court from all over the world for study and discussion. Akbar's courts at Delhi, Agra, and Fatehpur Sikri became centers of the arts, letters, and learning. Perso-Islamic culture began to merge and blend with indigenous Indian elements, and a distinct Indo-Persian culture emerged characterised by Mughal style arts, painting, and architecture. Disillusioned with orthodox Islam and perhaps hoping to bring about religious unity within his empire, Akbar promulgated Din-i-Ilahi, a syncretic creed derived from Islam, Hinduism, Zoroastrianism, and Christianity. A simple, monotheistic cult, tolerant in outlook, it centered on Akbar as a prophet, for which he drew the ire of the ulema and orthodox Muslims.

Akbar's reign significantly influenced the course of Indian history. During his rule, the Mughal empire tripled in size and wealth. He created a powerful military system and instituted effective political and social reforms. By abolishing the sectarian tax on non-Muslims and appointing them to high civil and military posts, he was the first Mughal ruler to win the trust and loyalty of the native subjects. He had Sanskrit literature translated, participated in native festivals, realizing that a stable empire depended on the co-operation and good-will of his subjects. Thus, the foundations for a multicultural empire under Mughal rule was laid during his reign. Akbar was succeeded as emperor by his son, Jahangir.

Nasir ud-din Muhammad Humayun

Nasir ud-din Muhammad Humayun (7 March 1508 AD – OS 17 January 1556 AD) was the second Mughal Emperor who ruled a large territory consisting of what is now Afghanistan, Pakistan, and parts of northern India from 1530–1540 and again from 1555–1556. Like his father, Babur, he lost his kingdom early, but with Persian aid, he eventually regained an even larger one. On the eve of his death in 1556, the Mughal empire spanned almost one million square kilometers.

He succeeded his father in India in 1530, while his half-brother Kamran Mirza, who was to become a rather bitter rival, obtained the sovereignty of Kabul and Lahore, the more northern parts of their father's empire. He originally ascended the throne at the age of 23 and was somewhat inexperienced when he came to power.

Humayun lost Mughal territories to the Pashtun noble, Sher Shah Suri, and, with Persian aid, regained them 15 years later. Humayun's return from Persia, accompanied by a large retinue of Persian noblemen, signaled an important change in Mughal court culture. The Central Asian origins of the dynasty were largely overshadowed by the influences of Persian art, architecture, language and literature. There are many stone carvings and thousands of Persian manuscripts in India from the time of Humayun.

Subsequently, in a very short time, Humayun was able to expand the Empire further, leaving a substantial legacy for his son, Akbar. His peaceful personality, patience and non-provocative methods of speech earned him the title ’Insān-i-Kamil (‘Perfect Man’), among the Mughals.[full citation needed]

"Honesty is the best policy"

Honesty refers to a facet of moral character and connotes positive and virtuous attributes such as integrity, truthfulness, and straightforwardness, including straightforwardness of conduct, along with the absence of lying, cheating, theft, etc. Furthermore, honesty means being trustworthy, loyal, fair, and sincere.

Honesty is valued in many ethnic and religious cultures.

"Honesty is the best policy" is a proverb of Benjamin Franklin; however, the quote "Honesty is the first chapter in the book of wisdom" is attributed to Thomas Jefferson, as used in a letter to Nathaniel Macon.

William Harvey

William Harvey (1 April 1578 – 3 June 1657) was an English physician. He was the first to describe completely and in detail the systemic circulation and properties of blood being pumped to the body by the heart, though earlier writers had provided precursors of the theory.After his death the William Harvey Hospital was constructed in the town of Ashford, several miles from his birthplace of Folkestone.

Charles Robert Darwin

Charles Robert Darwin,(12 February 1809 – 19 April 1882) was an English naturalist famous primarily for his theory of biological evolution.[He established that all species of life have descended over time from common ancestors,and along with Alfred Russell Wallace introduced the scientific theory that this branching pattern of evolution resulted from a

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species.By the 1870s the scientific community and much of the general public had accepted evolution as a fact. However, many favoured competing explanations and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution.In modified form, Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. Studies at the University of Cambridge encouraged his passion for natural science.His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's uniformitarian ideas, and publication of his journal of the voyage made him famous as a popular author.

Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations and in 1838 conceived his theory of natural selection.Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had priority.He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay which described the same idea, prompting immediate joint publication of both of their theories.Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature.In 1871 he examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed by The Expression of the Emotions in Man and Animals. His research on plants was published in a series of books, and in his final book, he examined earthworms and their effect on soil.

In recognition of Darwin's pre-eminence as a scientist, he was honoured with a major ceremonial funeral and buried in Westminster Abbey, close to John Herschel and Isaac Newton.Darwin has been described as one of the most influential figures in human history.
process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

Christian Friedrich Samuel Hahnemann


Christian Friedrich Samuel Hahnemann (10 April 1755– 2 July 1843) was a German physician, best known for creating a system of alternative medicine called homeopathy.
Contents

Christian Friedrich Samuel Hahnemann was born in Meissen, Saxony, near Dresden. His father, along with many other family members, was a painter and designer of porcelain, for which the town of Meissen is famous.

As a young man, Hahnemann became proficient in a number of languages, including English, French, Italian, Greek and Latin. He eventually made a living as a translator and teacher of languages, gaining further proficiency in "Arabic, Syriac, Chaldaic and Hebrew".

Hahnemann studied medicine for two years at Leipzig. Citing Leipzig's lack of clinical facilities, he moved to Vienna, where he studied for ten months.After one term of further study, he graduated MD at the University of Erlangen on 10 August 1779, qualifying with honors. His poverty may have forced him to choose Erlangen, as the school's fees were lower.Hahnemann's thesis was titled Conspectus adfectuum spasmodicorum aetiologicus et therapeuticus.

Sir Alexander Fleming

Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish biologist, pharmacologist and botanist. He wrote many articles on bacteriology, immunology, and chemotherapy. His best-known discoveries are the enzyme lysozyme in 1923 and the antibiotic substance penicillin from the mould Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain.

In 1999, Time magazine named Fleming one of the 100 Most Important People of the 20th Century, stating:

    It was a discovery that would change the course of history. The active ingredient in that mould, which Fleming named penicillin, turned out to be an infection-fighting agent of enormous potency. When it was finally recognized for what it was, the most efficacious life-saving drug in the world, penicillin would alter forever the treatment of bacterial infections. By the middle of the century, Fleming's discovery had spawned a huge pharmaceutical industry, churning out synthetic penicillins that would conquer some of mankind's most ancient scourges, including syphilis, gangrene and tuberculosis.

Albert Einstein

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"),he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".The latter was pivotal in establishing quantum theory.

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the large-scale structure of the universe.

He was visiting the United States when Adolf Hitler came to power in 1933 and did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the U.S., becoming an American citizen in 1940.On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential developing of "extremely powerful bombs of a new type" and recommending that the U.S. begin similar research. This eventually led to what would become the Manhattan Project. Einstein was in support of defending the Allied forces, but largely denounced using the new discovery of nuclear fission as a weapon. Later, with the British philosopher Bertrand Russell, Einstein signed the Russell–Einstein Manifesto, which highlighted the danger of nuclear weapons. Einstein was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955.

Einstein published more than 300 scientific papers along with over 150 non-scientific works.His great intellectual achievements and originality have made the word "Einstein" synonymous with genius.

James Watt

James Watt(19 January 1736 – 25 August 1819)was a Scottish inventor and mechanical engineer whose improvements to the Newcomen steam engine were fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world.

While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and re-heating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually he adapted his engine to produce rotary motion, greatly broadening its use beyond pumping water.

Watt attempted to commercialise his invention, but experienced great financial difficulties until he entered a partnership with Matthew Boulton in 1775. The new firm of Boulton and Watt was eventually highly successful and Watt became a wealthy man. In his retirement, Watt continued to develop new inventions though none were as significant as his steam engine work. He died in 1819 at the age of 83. Watt has been described as one of the most influential figures in human history.

He developed the concept of horsepower and the SI unit of power, the watt, was named after him.

Thomas Alva Edison

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park",he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.

Edison is the fourth most prolific inventor in history, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany. He is credited with numerous inventions that contributed to mass communication and, in particular, telecommunications. These included a stock ticker, a mechanical vote recorder, a battery for an electric car, electrical power, recorded music and motion pictures.

His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Edison developed a system of electric-power generation and distribution
to homes, businesses, and factories – a crucial development in the modern industrialized world. His first power station was on Pearl Street in Manhattan, New York.

The Wright brothers

The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American brothers, inventors, and aviation pioneers who were credited with inventing and building the world's first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight, on December 17, 1903. From 1905 to 1907, the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.

The brothers' fundamental breakthrough was their invention of three-axis control, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium.This method became standard and remains standard on fixed-wing aircraft of all kinds.From the beginning of their aeronautical work, the Wright brothers focused on developing a reliable method of pilot control as the key to solving "the flying problem". This approach differed significantly from other experimenters of the time who put more emphasis on developing powerful engines.Using a small homebuilt wind tunnel, the Wrights also collected more accurate data than any before, enabling them to design and build wings and propellers that were more efficient than any before.Their

They gained the mechanical skills essential for their success by working for years in their shop with printing presses, bicycles, motors, and other machinery. Their work with bicycles in particular influenced their belief that an unstable vehicle like a flying machine could be controlled and balanced with practice.From 1900 until their first powered flights in late 1903, they conducted extensive glider tests that also developed their skills as pilots. Their bicycle shop employee Charlie Taylor became an important part of the team, building their first aircraft engine in close collaboration with the brothers.
first U.S. patent, 821,393, did not claim invention of a flying machine, but rather, the invention of a system of aerodynamic control that manipulated a flying machine's surfaces.

Bangla town in London!




Winding through fields, the street was formerly called Whitechapel Lane. It derives its current name from brick and tile manufacture started in the 15th century, which used the local brick earth deposits.By the 17th century, the street was being developed from the south as a result of expanding population.

Brewing came to Brick Lane before 1680, with water drawn from deep wells. One brewer was Joseph Truman, first recorded in 1683. His family, particularly Benjamin Truman, went on to establish the sizeable Black Eagle Brewery on Brick Lane.The Brick Lane Market first developed in the 17th century for fruit and vegetables sold outside the City.

Successive waves of immigrants settled in the area: in the 17th century, French Huguenots expanded into the area for housing; the master weavers were based in Spitalfields.Starting with the Huguenots, the area became a centre for weaving, tailoring and the developing clothing industry. It continued to attract immigrants, who provided semi- and unskilled labour.

In the 19th century, Irish,and Ashkenazi Jews immigrated to the area.jewish immigration continued into the early 20th century.

The Sunday market, like the ones on Petticoat Lane and nearby Columbia Road, dates from a dispensation given by the government to the Jewish community in the 19th century. At the time, there were no Sunday markets open because of the Christian observance of Sabbath. Located at the junction with of Cheshire and Sclater streets, the market sells bric-a-brac as well as fruit, vegetables and many other items. Near the junction with Hanbury Street are two indoor markets; Upmarket and Backyard Market. In 2010, the Brick Lane Farmers' Market opened, intended to be held every Sunday in nearby Bacon Street;it has now closed.
In the later 20th century, Bangladeshis comprised the major group of immigrants and gradually predominated in the area.Many Bangladeshi immigrants to Brick Lane were from the Greater Sylhet region. These settlers helped shape Bangladeshi migration to Britain; many families from Jagannathpur and Bishwanath tend to live in the Brick Lane area.

Rishi Bankim Chandra Chattopadhyay

Rishi Bankim Chandra Chattopadhyay(27 June 1838 – 8 April 1894)was a Bengali writer, poet and journalist.He was the composer of India’s national song Vande Mataram, originally a Bengali and Sanskrit stotra personifying India as a mother goddess and inspiring the activists during the Indian Freedom Movement. Bankim Chandra wrote 13 novels and several ‘serious, serio-comic, satirical, scientific and critical treaties’ in Bengali. His works were widely translated into other regional languages of India as well as in English.

Bankim Chandra was born to an orthodox Brahmin family at Kanthalpara, North 24 Parganas. He was educated at Hoogly College and Presidency College, Calcutta. He was one of the first graduates of the University of Calcutta. From 1858, until his retirement in 1891, he served as a deputy magistrate and deputy collector in the Government of British India.

Bankim Chandra is widely regarded as a key figure in literary renaissance of Bengal as well as India. Some of his writings, including novels, essays and commentaries, were a breakaway from traditional verse-oriented Indian writings, and provided an inspiration for authors across India.

When Bipin Chandra Pal decided to start a patriotic journal in August 1906, he named it Vande Mataram, after Bankim Chandra's song. Lala Lajpat Rai also published a journal of the same name.

Ishwar Chandra Vidyasagar

Ishwar Chandra Vidyasagar CIE (26 September 1820 – 29 July 1891),Ishwar Chandra Bandopadhyay was an Indian Bengali polymath and a key figure of the Bengal Renaissance.Vidyasagar was a philosopher, academic, educator, writer, translator, printer, publisher, entrepreneur, reformer, and philanthropist. His efforts to simplify and modernize Bengali prose were significant. He also rationalized and simplified the Bengali alphabet and type, which had remained unchanged since Charles Wilkins and Panchanan Karmakar had cut the first (wooden) Bengali type in 1780.He received the title "Vidyasagar" ("Ocean of learning" or "Ocean of knowledge") from the Calcutta Sanskrit College (where he graduated), due to his excellent performance in Sanskrit studies and philosophy. In Sanskrit, Vidya means knowledge or learning and Sagar means ocean or sea. This title was mainly given for his vast knowledge in all subjects which was compared to the vastness of the ocean.

Michael Madhusudan Dutt

Michael Madhusudan Dutt
or Michael Madhusudan Dutt(25 January 1824 – 29 June 1873) was a popular 19th-century Bengali poet and dramatist.He was born in Sagordari (Bengali: সাগরদাঁড়ি), on the bank of Kopotaksho (Bengali: কপোতাক্ষ) River, a village in Keshabpur Upazila, Jessore District, East Bengal (now in Bangladesh). His father was Rajnarayan Dutt, an eminent lawyer, and his mother was Jahnabi Devi. He was a pioneer of Bengali drama. His famous work Meghnad Bodh Kavya (Bengali: মেঘনাদবধ কাব্য), is a tragic epic. It consists of nine cantos and is exceptional in Bengali literature both in terms of style and content. He also wrote poems about the sorrows and afflictions of love as spoken by women.

From an early age, Dutt aspired to be an Englishman in form and manner. Born to a Hindu landed-gentry family, he converted to Christianity as a young man, to the ire of his family, and adopted the first name Michael. In later life he regretted his attraction to England and the Occident. He wrote ardently of his homeland in his poems and sonnets from this period.

Dutt is widely considered to be one of the greatest poets in Bengali literature and the father of the Bengali sonnet. He pioneered what came to be called amitrakshar chhanda (blank verse). Dutt died in Kolkata, India on 29 June 1873.

Kazi Nazrul

Kazi Nazrul Islam known popularly as Nazrul, was a Bengali poet, musician and revolutionary who pioneered poetic works espousing intense spiritual rebellion against fascism and oppression. His poetry and nationalist activism earned him the popular title of "বিদ্রোহী কবি" Bidrohī Kobi (Rebel Poet). Accomplishing a large body of acclaimed works through his life, Nazrul is officially recognised as the national poet of Bangladesh and highly commemorated in India.

Born into a Bengali Muslim Quazi (Kazi) family, Nazrul received religious education and worked as a muezzin at a local mosque. He learned of poetry, drama, and literature while working with theatrical groups. After serving in the British Indian Army, Nazrul established himself as a journalist in Calcutta. He assailed the British Raj in India and preached revolution through his poetic works, such as "Bidrohi" ("The Rebel") and "Bhangar Gaan" ("The Song of Destruction"), as well as his publication "Dhumketu" ("The Comet"). His impassioned activism in the Indian independence movement often led to his imprisonment by British authorities. While in prison, Nazrul wrote the "Rajbandir Jabanbandi" "রাজবন্দীর জবানবন্দী" ("Deposition of a Political Prisoner"). Exploring the life and conditions of the downtrodden masses of India, Nazrul worked for their emancipation.

Nazrul's writings explore themes such as love, freedom, and revolution; he opposed all bigotry, including religious and gender. Throughout his career, Nazrul wrote short stories, novels, and essays but is best known for his poems, in which he pioneered new forms such as Bengali ghazals. Nazrul wrote and composed music for his nearly 4,000 songs (including gramophone records),collectively known as Nazrul geeti (Nazrul songs), which are widely popular today. In 1942 at the age of 43 he began suffering from an unknown disease, losing his voice and memory. It is often said, the reason was slow poisoning by British Government but later a medical team in Vienna diagnosed the disease as Morbus Pick,a rare incurable neurodegenerative disease. It caused Nazrul's health to decline steadily and forced him to live in isolation for many years. Invited by the Government of Bangladesh, Nazrul and his family moved to Dhaka in 1972, where he died four years later.

Rabindranath Thakur

Rabindranath Thakur was a Bengali polymath who reshaped his region's literature and music. Author of Gitanjali and its "profoundly sensitive, fresh and beautiful verse",he became the first non-European to win the Nobel Prize in Literature in 1913.In translation his poetry was viewed as spiritual and mercurial; however, his "elegant prose and magical poetry" remain largely unknown outside Bengal. Tagore introduced new prose and verse forms and the use

of colloquial language into Bengali literature, thereby freeing it from traditional models based on classical Sanskrit. He was highly influential in introducing the best of Indian culture to the West and vice versa, and he is generally regarded as the outstanding creative artist of modern South Asia.

A Pirali Brahmin from Calcutta, Tagore wrote poetry as an eight-year-old.At age sixteen, he released his first substantial poems under the pseudonym Bhānusiṃha ("Sun Lion"), which were seized upon by literary authorities as long-lost classics.He graduated to his first short stories and dramas—and the aegis of his birth name—by 1877. As a humanist, universalist internationalist, and strident anti-nationalist he denounced the Raj and advocated independence from Britain. As an exponent of the Bengal Renaissance, he advanced a vast canon that comprised paintings, sketches and doodles, hundreds of texts, and some two thousand songs; his legacy endures also in the institution he founded, Visva-Bharati University.

Tagore modernised Bengali art by spurning rigid classical forms and resisting linguistic strictures. His novels, stories, songs, dance-dramas, and essays spoke to topics political and personal. Gitanjali (Song Offerings), Gora (Fair-Faced), and Ghare-Baire (The Home and the World) are his best-known works, and his verse, short stories, and novels were acclaimed—or panned—for their lyricism, colloquialism, naturalism, and unnatural contemplation. His compositions were chosen by two nations as national anthems: India's Jana Gana Mana and Bangladesh's Amar Shonar Bangla.

Mount Everest

Mount Everest is the Earth's highest mountain, with a peak at 8,848 metres (29,029 ft) above sea level and the 5th tallest mountain measured from the centre of the Earth.It is located in the Mahalangur section of the Himalayas. The international border between China and Nepal runs across the precise summit point. Its massif includes neighboring peaks Lhotse, 8,516 m (27,940 ft); Nuptse, 7,855 m (25,771 ft) and Changtse, 7,580 m (24,870 ft).

In 1856, the Great Trigonometric Survey of British India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). The current official height of 8,848 m (29,029 ft) as recognized by Nepal and China was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975. In 1865, Everest was given its official English name by the Royal Geographical Society upon a recommendation by Andrew Waugh, the British Surveyor General of India. Waugh named the mountain after his predecessor in the post, Sir George Everest. Although Tibetans had called Everest "Chomolungma" for centuries, Waugh was unaware of this because Tibet and Nepal were closed to foreigners at the time thus preventing any attempts to obtain local names.

Mount Everest attracts many highly experienced mountaineers as well as capable climbers willing to hire professional guides. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the standard route) and the other from the north in Tibet. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, wind as well as significant objective hazards from avalanches and the Khumbu Icefall. While the overwhelming majority of climbers will use bottled oxygen in order to reach the top, some climbers have summitted Everest without supplemental oxygen.

The goal of reaching Everest's summit for the first time was initially taken up by tenacious British mountaineers. With Nepal not allowing foreigners into the country at the time, the British made several attempts on the north ridge route from the Tibetan side. After the first reconnaissance expedition by the British in 1921 reached 7,000 m (22,970 ft) on the North Col, the 1922 expedition pushed the North ridge route up to 8,320 m (27,300 ft) marking the first time a human had climbed above 8,000 m (26,247 ft). Tragedy struck on the descent from the North col when seven porters were killed in an avalanche. The 1924 expedition resulted in the greatest mystery on Everest to this day: George Mallory and Andrew Irvine made a final summit attempt on June 8 but never returned; sparking debate as to whether they were the first to reach the top. They had been spotted high on the mountain that day but disappeared in the clouds, never to be seen again until Mallory's body was found in 1999 at 8,155 m (26,755 ft) on the North face. Tenzing Norgay and Edmund Hillary made the first official ascent of Everest in 1953 using the southeast ridge route. Tenzing had reached 8,595 m (28,199 ft) the previous year as a member of the 1952 Swiss expedition.

The Sydney Harbour Bridge

The Sydney Harbour Bridge is a steel through arch bridge across Sydney Harbour that carries rail, vehicular, bicycle and pedestrian traffic between the Sydney central business district (CBD) and the North Shore. The dramatic view of the bridge, the harbour, and the nearby Sydney Opera House is an iconic image of Sydney, New South Wales, and Australia. The bridge is nicknamed "The Coathanger" because of its arch-based design.

Under the directions of Dr J.J.C. Bradfield of the NSW Department of Public Works, the bridge was designed and built by British firm Dorman Long and Co Ltd of Middlesbrough and opened in 1932.The bridge's design was influenced by the Hell Gate Bridge in New York.It is also the sixth longest spanning-arch bridge in the world, and it is the tallest steel arch bridge, measuring 134 metres (440 ft) from top to water level.It was also the world's widest long-span bridge, at 48.8 meters (160 feet) wide, until construction of the new Port Mann Bridge in Vancouver.
