History ofThe π


The History of π




In the long history of the number π, there have been many twists and turns, many inconsistencies that reflect the condition of the human race as a whole. Through each major period of world history and in each regional area, the state of intellectual thought, the state of mathematics, and hence the state of π, has been dictated by the same socio-economic and geographic forces as every other aspect of civilization. The following is a brief history, organized by period and region, of the development of our understanding of the number π.

In ancient times, π was discovered independently by the first civilizations to begin agriculture. Their new sedentary life style first freed up time for mathematical pondering, and the need for permanent shelter necessitated the development of basic engineering skills, which in many instances required a knowledge of the relationship between the square and the circle (usually satisfied by finding a reasonable approximation of π). Although there are no surviving records of individual mathematicians from this period, historians today know the values used by some ancient cultures. Here is a sampling of some cultures and the values that they used: Babylonians - 3 1/8, Egyptians - (16/9)^2, Chinese - 3, Hebrews - 3 (implied in the Bible, I Kings vii, 23).

The first record of an individual mathematician taking on the problem of π (often called "squaring the circle," and involving the search for a way to cleanly relate either the area or the circumference of a circle to that of a square) occurred in ancient Greece in the 400's B.C. (this attempt was made by Anaxagoras). Based on this fact, it is not surprising that the Greek culture was the first to truly delve into the possibilities of abstract mathematics. The part of the Greek culture centered in Athens made great leaps in the area of geometry, the first branch of mathematics to be thoroughly explored. Antiphon, an Athenian philosopher, first stated the principle of exhaustion (click on Antiphon for more info). Hippias of Elis created a curve called the quadratrix, which actually allowed the theoretical squaring of the circle, though it was not practical.

In the late Greek period (300's-200's B.C.), after Alexander the Great had spread Greek culture from the western borders of India to the Nile Valley of Egypt, Alexandria, Egypt became the intellectual center of the world. Among the many scholars who worked at the University there, by far the most influential to the history of π was Euclid. Through the publishing of Elements, he provided countless future mathematicians with the tools with which to attack the π problem. The other great thinker of this time, Archimedes, studied in Alexandria but lived his life on the island of Sicily. It was Archimedes who approximated his value of π to about 22/7, which is still a common value today.

Archimedes was killed in 212 B.C. in the Roman conquest of Syracuse. In the years after his death, the Roman Empire gradually gained control of the known world. Despite their other achievements, the Romans are not known for their mathematical achievements. The dark period after the fall of Rome was even worse for π. Little new was discovered about π until well into the decline of the Middle Ages, more than a thousand years after Archimedes' death. (For an example of at least one mediaeval mathematician, see Fibonacci.)


While π activity stagnated in Europe, the situation in other parts of the world was quite different. The Mayan civilization, situated on the Yucatan Peninsula in Central America, was quite advanced for its time. The Mayans were top-notch astronomers, developing a very accurate calendar. In order to do this, it would have been necessary for them to have a fairly good value for π. Though no one knows for sure (nearly all Mayan literature was burned during the Spanish conquest of Mexico), most historians agree that the Mayan value was indeed more accurate than that of the Europeans. The Chinese in the 5th century calculated π to an accuracy not surpassed by Europe until the 1500's. The Chinese, as well as the Hindus, arrived at π in roughly the same method as the Europeans until well into the Renaissance, when Europe finally began to pull ahead.

During the Renaissance period, π activity in Europe began to finally get moving again. Two factors fueled this acceleration: the increasing importance of mathematics for use in navigation, and the infiltration of Arabic numerals, including the zero (indirectly introduced from India) and decimal notation (yes, the great mathematicians of antiquity made all of their discoveries without our standard digits of 0-9!). Leonardo Da Vinci and Nicolas Copernicus made minimal contributions to the π endeavor, but François Viète actually made significant improvements to Archimedes' methods. The efforts of Snellius, Gregory, and John Machin eventually culminated in algebraic formulas for π that allowed rapid calculation, leading to ever more accurate values of π during this period.

In the 1700's the invention of calculus by Sir Isaac Newton and Leibniz rapidly accelerated the calculation and theorization of π. Using advanced mathematics, Leonhard Euler found a formula for π that is the fastest to date. In the late 1700's Lambert (Swiss) and Legendre (French) independently proved that π is irrational. Although Legendre predicted that π is also transcendental, this was not proven until 1882 when Lindemann published a thirteen-page paper proving the validity of Legendre's statement. Also in the 18th century, George Louis Leclerc, Comte de Buffon, discovered an experimental method for calculating π. Pierre Simon Laplace, one of the founders of probability theory, followed up on this in the next century. Click here to learn more about Buffon's and Laplace's method.

Starting in 1949 with the ENIAC computer, digital systems have been calculating π to incredible accuracy throughout the second half of the twentieth century. Whereas ENIAC was able to calculate 2,037 digits, the record as of the date of this article is 206,158,430,000 digits, calculated by researchers at the University of Tokyo. It is highly probable that this record will be broken, and there is little chance that the search for ever more accurate values of π will ever come to an end.

History Of Mathematics



Every culture on earth has developed some mathematics. In some cases, this mathematics has spread from one culture to another. Now there is one predominant international mathematics, and this mathematics has quite a history. It has roots in ancient Egypt and Babylonia, then grew rapidly in ancient Greece. Mathematics written in ancient Greek was translated into Arabic. About the same time some mathematics of India was translated into Arabic. Later some of this mathematics was translated into Latin and became the mathematics of Western Europe. Over a period of several hundred years, it became the mathematics of the world.
There are other places in the world that developed significant mathematics, such as China, southern India, and Japan, and they are interesting to study, but the mathematics of the other regions have not had much influence on current international mathematics. There is, of course, much mathematics being done these and other regions, but it is not the traditional math of the regions, but international mathematics.

By far, the most significant development in mathematics was giving it firm logical foundations. This took place in ancient Greece in the centuries preceding Euclid. See Euclid's Elements. Logical foundations give mathematics more than just certainty-they are a tool to investigate the unknown.

By the 20th century the edge of that unknown had receded to where only a few could see. One was David Hilbert, a leading mathematician of the turn of the century. In 1900 he addressed the International Congress of Mathematicians in Paris, and described 23 important mathematical problems.

Mathematics continues to grow at a phenomenal rate. There is no end in sight, and the application of mathematics to science becomes greater all the time.

History Of Surat


Surat (Gujarati: સુરત, Hindi: सूरत) formerly known as Suryapur, is the commercial capital city of the Indian state of Gujarat and also Second largest commercial hub of western India after Mumbai. The city proper is the one of the most populous cities in the world. Surat is the administrative capital of Surat district and Surat Metropolitan Region. Surat is India’s eighth largest metropolitan city. Surat is India’s cleanest Mertropolitan Region

The city is situated on the left bank of the Tapti River, 14 miles from its mouth. The Population of Surat with its twin city Navsari is above 6.2 million as of 2010. A moat divides the older parts of the city, with its narrow streets and handsome houses, and the newer suburbs. The city is largely recognized for its textile and diamond businesses. It is also known as the diamond capital of the world and the textile capital of India. 92% of the world’s diamonds are cut and polished in Surat. Surat is also the Third cleanest city in India after Chandigarh and Mysore. Surat was once the largest city in India. It has one of the highest GDP growth rates in India at 11.5% as of 2008. Surat was the primary port of India during the Mughal period, a distinction it lost to Bombay during the British Raj.

History
Surat is mentioned in the Sanskrit epic, the Mahābhārata when Lord Krishna stopped there en route from Mathura to Dwarka. According to other later Sanskrit records, the area was ruled by the Western Chālukyas in 610 CE, and continued to be ruled by Hindu kings until it was captured by one of the generals of Quṭbuddīn Aibak. The Parsis started to settle there in the 12th century, and added greatly to its prosperity. In the early centuries during the reign of Rishika Lekhadia, the port of Surat was used as the gateway to Mecca for pilgrims of the Hajj from India’s interior regions. Both the Makkai Pool and the Mughal Sarai guest house for hajjis (pilgrims) are indicators of this historical significance.

Local traditions state that the city was founded in the last years of the fifteenth century by a Brahman named Gopi, who called it Suryapūr (City of the Sun). In 1512 and 1530 Surat was burned and ravaged by the Portuguese Empire who were trying to maintain influence in the area. In 1513, the Portuguese traveler, Duarte Barbosa, described Surat as an important seaport, frequented by many ships from Malabar and various parts of the world. By 1520, the name of the city was Surat.

Surat eclipsed Khambhat as the major port of western India, when Khambhat’s harbour began to silt up by the end of fifteenth century. During the reigns of the Mughal emperor Akbar, Jahāngīr and Shāh Jahān, Surat rose to become a chief commercial city of India and an imperial mint was established there. As the major port on the west coast of India, Surat also served as the port for the Hajj to Mecca. At the end of the 16th century, the Portuguese were undisputed masters of the Surat sea trade. There still is a picturesque fortress on the banks of the river built in 1540.

In 1608, ships from the British East India Company started docking in Surat, using it as a trade and transit point. In 1613, the British Captain Best, followed by Captain Downton, overcame Portuguese naval supremacy and obtained an imperial firman establishing a British factory at Surat following the Battle of Swally. The city was made the seat of a presidency under the British East India Company after the success of the embassy of Sir Thomas Roe to the court of emperor Jehangir. The Dutch also founded a factory.

At its zenith, Surat was popularly viewed as the city of Kubera, the God of Wealth. In 1664 the Maratha King Shivaji attacked Surat, a key Mughal power centre, and a wealthy port town which generated a million rupees in taxes. (see- Battle of Surat). When Shivaji arrived in Surat, he demanded tribute from the Mughal commander of the army stationed for port security. The tribute was refused and instead of battling the Marathas, the Mughal commander(Stationed at the Surat fort) sent an emissary to assassinate Shivaji, but in vain. Shivaji conquered the city and forces under his command exacted their revenge. Shivaji’s army sacked Surat for nearly 3 weeks, looting both the Mughal and Portuguese trading centers. Men’s were killed but the poor were spared.

The prosperity of Surat received a fatal blow when Bombay was ceded to the British as part of the dowry for Catherine of Braganza’s wedding to Charles II in 1662. Shortly afterwards, in 1668, the British East India company established a factory in Bombay (Mumbai) and Surat began its relative decline concurrent with the rise of British interests in Bombay.

Surat was sacked again by Shivaji in 1670. By 1687, the British East India Company had moved the presidency to Bombay. At its height, Surat’s population reached an estimated 800,000, but by the middle of the 19th century the number had fallen to 80,000. The British took control of Surat again in 1759, and assumed all government powers of the city in 1800.

The city and the surrounding district remained comparatively tranquil during British rule. Even during the Revolt of 1857 (also known as the first struggle for India’s independence), peace was not disturbed, owing to the largely mercantile interests of the local population.In the 19th century the Bawamia family was the wealthiest and most powerful family in the city of Surat, they were also heavily involved in the development of the city by focusing on maximizing exports to increase revenue and hence increase savings which led to investment in the diamond industry.

A fire and a flood in 1837 destroyed many of buildings of Surat. Among the interesting monuments that survive that destruction are the tombs of English and Dutch merchants and their families, dating to the 17th century, including those of the Oxenden brothers.

By the early 20th century, the population had slowly climbed to 119,306 and Surat was a center of trade and manufacturing, although some of its former industries, such as shipbuilding, were extinct. There were cotton mills, factories for ginning and pressing cotton, rice-cleaning mills and paper mills. Fine cotton goods were woven on hand-looms, and there were special manufactures of silk brocade and gold embroidery (known as Jari). The chief trades were organized in guilds. Manufacturing and trading brought an eclectic mix of ethnicity to the city, making Surat’s culture unique.

In 1992, violent riots took place between Hindus and Muslims, the first and worst of their kind in the modern history of Surat. In 1994, a combination of heavy rains and blocked drains led to flooding of the city. A number of dead street animals and public waste were not removed in time and a plague epidemic spread through the city, which caused a number of countries to impose travel and trade sanctions. The municipal commissioner during that time, S. R. Rao and the people of Surat worked hard in the late 1990s to clean the city.

Old English & Dutch Cemetery
The structure of the Old English and Old Dutch cemeteries in Surat is dominated by the largest monuments of Europeans in all over India. These graves are also some of the oldest tombs which have survived from the earliest times of British and Dutch activities at Surat.

The English traders settled in Surat in 1608 followed by the Dutch in 1617. French and also Swedes – even for just a short period – commenced trading-enterprises here. However, it seems that there are no re-mainders of their burial culture left today. Along with the Dutch also Armenian traders left a quite big cemetery in Surat. Both nations share the same burial ground only separated by a wall.

History Of Ahmedabad


Ahmedabad or Ahmadabad is the largest city in state of Gujarat (there are 28 states, Gujarat is the westernmost one)and the sixth largest city in India has
a population of over 3,7 million people. The city is also sometimes called Karnavati , an older name and as Amdavad in colloquial Gujarati .

Ahmedabad is the administrative center of Ahmedabad District , and was the former capital of Gujarat State from 1960 to 1970 , when Gandhinagar replaced it.

The city was founded in the 15th century by Sultan Ahmed Shah on the Sabarmati river , and served as capital of the Sultanate of Gujarat. The historic center of Ahmedabad is presently a thriving business district.

Ahmedabad is mainly divided in two parts, the old city, and new city. The old city has developed rather haphazardly, and most of the roads are narrow and crowded during business hours. The new city has well-structured, wide roads. A wide variety of shops and businesses exist in the city.

In addition to its role as a commercial center, Ahmedabad is also an important industrial center, with chemical and textile industries. Ahmedabad is often described as the Manchester of the East, because of its once-booming textile industry. Ahmedabad is a very beautiful city.


History
The History of Ahmedabad begins in the eleventh century with the Solanki King Karandev I, ruler of Anhilwara (modern Patan). He waged a war against the Bhil King Ashapall or Ashaval, and after his victory established a city called Karnavati on the banks of the Sabarmati at site of modern Ahmedabad. Solanki rule lasted until the thirteenth century, when Gujarat came under the control of the Vaghela dynasty of Dwarka. Gujarat was conquered by the Sultanate of Delhi at the end of the thirteenth century.



In 1411 , the rule of the Muzaffarid dynasty was established in Gujarat. According to tradition, Sultan Ahmed Shah, while camping on the banks of the River Sabarmati, saw a hare chasing a dog. Impressed by this act of bravery, the Sultan, who had been looking for a place to build his new capital, decided to locate the capital here and called it Ahmedabad.

In 1487, Mahmud Begada, the grandson of Ahmed Shah, fortified the city with an outer wall 10 km (6 miles) in circumference and consisting of twelve gates, 189 bastions and over 6,000 battlements. Ahmedabad was ruled by the Muzaffarid dynasty until 1573 when Muzaffar II was the Sultan of Ahmedabad. Gujarat was then conquered by the Mughal emperor Akbar in 1573. During the Mughal reign, Ahmedabad became one of the Empire's thriving centres of trade, mainly in textiles, which were exported to as far as Europe. The Mughal ruler Shahjahan spent the prime of his life in the city, sponsoring the construction of the Moti Shahi Mahal in Shahibaug. The armies of the Maratha generals Raghunath Rao and Damaji Gaekwad captured the city and ended Mughal rule in Ahmedabad. A famine in 1630 and the constant conflicts between the Peshwa and the Gaekwad armies virtually destroyed many parts of the city, causing its population to flee. The British East India Company took over the city in 1818 as a part of the conquest of India. A military cantonment was established in 1824 and a municipal government in 1858. In 1864, a railway link between Ahmedabad and Mumbai (then Bombay) was established by the Bombay, Baroda, and Central India Railway (BB&CI), making Ahmedabad an important junction in the traffic and trade between northern and southern India. Large numbers of people migrated from rural areas to work in textile mills, establishing a robust industry.

The Indian independence movement developed strong roots in the city when, in 1915, Mahatma Gandhi established two ashrams — the Kochrab Ashram near Paldi in 1915 and the Satyagraha Ashram on the banks of the Sabarmati in 1917 — that would become centres of intense nationalist activities. During the mass protests against the Rowlatt Act in 1919, textile workers burned down 51 government buildings across the city in protest at a British attempt to extend wartime regulations after the First World War. In the 1920s, textile workers and teachers went on strike, demanding civil rights and better pay and working conditions. In 1930, Gandhi initiated the Salt Satyagraha from Ahmedabad by embarking from his ashram on the famous Dandi Salt March. The city administration and economic institutions were rendered functionless by the large masses of people who took to the streets in peaceful protests in the early 1930s, and again in 1942 during the Quit India movement. Following independence and the partition of India in 1947, the city was scarred by intense communal violence that broke out between Hindus and Muslims.

Ahmedabad became the capital of the new state of Gujarat after the bifurcation of the State of Bombay on 1 May 1960. During that period, a large number of educational and research institutions were founded in the city, making it a major centre of higher education, science and technology. Ahmedabad's economic base was diversified with the establishment of heavy and chemical industries in its vicinity around the same period. But the growth in the next two decades was punctuated by political events in and around the city. In February 1974, Ahmedabad occupied the centre stage in national politics with the launch of the Nav Nirman agitation — a protest against a 20% hike in the hostel food fees at the L.D. College of Engineering that snowballed into a mass agitation to remove Chimanbhai Patel, then-chief minister of Gujarat, on charges of corruption. In the 1980s, a reservation policy was introduced in the country, which led to anti-reservation protests in 1981 and 1985. The protests witnessed violent clashes between people belonging to various castes.

On 26 January 2001 a devastating earthquake struck the city, centred near Bhuj, measuring 6.9 on the Richter scale. As many as 50 multistory buildings collapsed, killing 752 people and devastating the city's infrastructure.

In recent years, the effects of globalisation and the liberalisation of the Indian economy has energised the city's economy. The city has witnessed the establishment of scientific and service industries, the expansion of the information technology sector, and significant improvements in transportation and communications. Ahmedabad's population is growing, which has resulted in a construction and housing boom. However, this has challenged the city's infrastructure and power supply.

History of "Mahatma Gandhi"


History of "Mahatma Gandhi"

He is a father of our nation played a key portrayal in winning freedom for India introduced the conception of Ahimsa and Nonviolence. Mahatma Gandhi popularly famed as Theologiser of Dry played a stellar enactment in Bharat's immunity endeavor. Innate in a Bania stemma in Kathiawar, Gujarat, his realistic obloquy was Mohandas Karamchand Statesman (M.K. Statesman). The claim Mahatma came to be associated with his epithet overmuch afterwards. Before Gandhiji's traveler on the Indian governmental situation, freedom effort was controlled only to the elite. Mahatma Gandhi's important attempt lay in the fact that he bridged the gulf between the intelligentsia and the masses and widened the conception of Swaraj to permit nearly every vista of party and moralistic reconstruction.

Remunerative extortion to Mahatma Solon on his end, famous soul Albert Einstein said, "Generations to proceed will scarce was calved on Oct 2, 1869, at Porbandar, a microscopic municipality on the west coast of India, which was then one of the umpteen tiny states in Kathiawar. Gandhiji was born in intermediate accumulation line of Vaishya caste. His fatherhood, Karamchand Gandhi, was a Dewan or Undercoat Minister of Porbandar. His fuss, Putlibai, was a really churchly peeress and mitt a esoteric effect on Gandhiji's remember. Gandhiji was a mediocre examinee and was too shy and coy.

Gandhiji was veracious in his direct appropriate Mahatma Gandhifrom the immaturity. There is a very famous incident in this warmheartedness. A Brits school inspector erstwhile came to Gandhiji's polish and set a spelling endeavor. Gandhiji spelled all the line correctly object kettledrum. The conference pedagogue noticed the identify and gestured Gandhiji to repeat the penalize spelling from the boy session next to him. Gandhiji refused to take the speck and was later scolded for his "stupidity".

Gandhiji was wedded at the age of cardinal to Kasturbai. He was in lyceum down at that quantify. Ulterior on in his lifespan, Gandhiji denounced the pattern of nipper family and termed it as heartless. After matriculating from the screaky refine, Gandhiji linked the Samaldas College in Bhavnagar. After the ending of Gandhiji's antecedent in 1885, a line suggested that if Gandhiji hoped to train his sire's piazza in the country company welcomed the line but his care was objected to the tune of going foreign. To win his parent's substance Gandhiji took a solemn vow not to speck wine, women and meat and remained sure to it throughout his fiat in England.

Gandhiji sailed for England on September 4, 1888. Initially he had travail in adjusting to Nation tariff and windward but soon he overcame it. Gandhiji complete his Law magnitude in 1891 and returned to Bharat. He definite to set up ineligible exercise in Bombay but couldn't found himself. Gandhiji returned to Rajkot but here also he could not sort untold progress. At this dimension Gandhiji conventional an message from Daddy Abdulla & Co. to happen to Southmost Continent on their behalf to apprize their substance in a proceeding. Gandhiji jumped at the tune and sailed for Southmost Africa in April 1893.



It was in Southeastward Continent that Gandhiji's translation from Mohandas to Mahatma took point. Gandhiji landed at Port and soon he realized the oppressive ambience of racist snobbishness against Indians who were situated in South Africa in huge drawing. After roughly a period's retard in Durban Gandhiji unexpended for Pretoria, the city of the State, in connection with a causa. When the procession reached Pietermaritzburg, the city of Port, at some 9 p.m. a soul rider who boarded the ride objected to the proximity of a "coloured" man in the compartment and Gandhji was sequent by a policeman pushed him out and his case was confiscated departed by the railway authorities. It was season and bitter raw. This incident denaturised Gandhiji's invigoration forever. He decided to attempt for the rights of Indians. Gandhiji union the Amerindic vocation in Southbound Africa and asked them to bury all distinctions of religion and caste. He advisable the manufacture of an association to aspect after the Asiatic settlers and offered his disentangled experience and services.

During his fiat in Southwesterly Africa, Gandhiji's invigoration underwent a exchange and he industrial most of his semipolitical ideas. Gandhiji decided toMahatma Statesman commit himself completely to the bringing of grouping. He realized that independent continence or brahmacharya was necessary for the usefulness as one could not lively both after the flesh and the animate. In 1906, Gandhiji took a vow of inviolable continence. In the row of his seek in Southeastern Continent, Gandhiji, industrial the concepts of Ahimsa (non-violence) and Satyagraha (holding instantaneous to abolitionist or resolve in a innocent grounds). Gandhiji's struggle gauge production and in 1914 in an arrangement in 1915 and on the advice of his semipolitical guru Gopal Avatar Gokhale, spent the rank gathering touring throughout the land to see the factual India.

After an assemblage of wandering, Gandhiji appointed consume on the bank of the river Sabarmati, on the outskirts of Ahmedabad, where he supported an ashram called Nonviolence Ashram. Gandhiji's freshman nonviolence in India was in Champaran, in Province, where he went in 1917 at the substance of a deficient peasants to examine into the grievances of the some used peasants of that regularise, who were compelled by Country dye planters to produce dyestuff on 15 pct of their industrialist and air with the livelong stomach for proceeds. Gandhiji's Satyagraha affected Brits authorities to set up a interrogation experiment in satyagraha in India greatly enhanced Gandhiji's reputation in the state.

In 1921, Gandhji gave the meet for Non-cooperation laxation against the ills of Country conception. Gandhiji's ring roused the sleeping commonwealth. Umteen Indians renounced their titles and honours, lawyers gave up their training, and students mitt colleges and schools. Non-cooperation movement also brought women into the realm of immunity essay for the ordinal indication. Non-cooperation happening gravely jolted the British governance. But the shitting ended in an anti-climax in February 1922. An irruption of mob aggression in Chauri Chaura so shocked and pained Statesman that he refused to talk the venture and undertook a vivace for fivesome days to atone for a evildoing sworn by others in a tell of mob neuroticism.

Gandhiji was sentenced to six eld internment but was released in 1924 on scrutiny settlings. For the incoming quint geezerhood Solon ostensibly retired from busy agitational opinion and devoted himself to the spreading of what he regarded as the essential national needs, namely, Hindu-Muslim wholeness, remotion of untouchability, position of women, popularization of hand-spinning and the reconstruction of village system.

On District 12, 1930 Gandhiji started the historic Dandi Territory to bust the law which had deprived the broke man of his justice to create his own tasteful. On Apr 6, 1930 Gandhiji poor the Nsaid law at the sea beach at Dandi. This plain act was directly followed by a nation-wide intractability of the law. This motility galvanized the intact nation and came to be notable as "Subject Disobedience Defecation". Within a few weeks near a cardinal thou men and women were in jailhouse, throwing right machinery of the Nation Governing out of appurtenances. This affected the then Vicereine Initial Rounded Plateau Conference.Mahatma Statesman Soon after his take from England Gandhiji was inactive without endeavor.

After the happening of 2nd Mankind War in 1939, Gandhiji again became existent in the political arena. Country Governing craved India's supply in the war and Congress in pass loved a clear-cut expectation of independency from Land regime. But Island governance dithered in its activity and on August 8, 1942 Gandhiji gave the demand for Depart India Defecation. Presently the Land Regime inactive Gandhiji and new top body of Congress. Disorders broke out directly all over Bharat and some intense demonstrations took area. While Gandhiji was in jailhouse his partner Kasturbai passed away. Gandhiji too had a wicked assault of Malaria. In vista of his deteriorating eudaimonia he was released from the slammer in May 1944.

Gear Experience War ended in 1945 and Britain emerged undefeated. In the general elections held in Britain in 1945, Labour Lot came to knowledge, and Atlee became the Quality Parson. He promised an embryotic sale of self Governing in India. A Housing Charge arrived from England to cover with Amerind leaders the proximo forge of a uncommitted and allied India, but failed to carry the Congress and Muslims unitedly. Bharat attained independency but Statesman's obstinance resulted in the separation of the state. Communal riots between Hindus and Muslims broke out in the region in the backwash of Religionist fundamentalists and on Jan 30, 1948 Gandhiji was photo lifeless by one much protestantism Nathu Ram Godse spell he was going for his eventide prayers. The antepenultimate line on the lips of Gandhiji were Hey Ram.

Jawaharlal Nehru Biography


Jawaharlal Nehru Biography

Born: November 14, 1889
Died: May 27, 1964




Achievements: Took active part in Non-Cooperation Movement; elected President of the Allahabad Municipal Corporation in 1924, and served for two years as the city's chief executive; Presided over Congress' annual session in Lahore in 1929 and passed a resolution demanding India's independence; elected as Congress President in 1936, 1937, and 1946; became first Prime Minister of independent India; was one of the main architects of Non Aligned Movement.

Jawaharlal Nehru, also known as Pandit Jawaharlal Nehru, was one of the foremost leaders of Indian freedom struggle. He was the favourite disciple of Mahatma Gandhi and later on went on to become the first Prime Minister of India. Jawahar Lal Nehru is widely regarded as the architect of modern India. He was very fond of children and children used to affectionately call him Chacha Nehru.

Jawahar Lal Nehru was born on November 14, 1889. His father Motilal Nehru was a famous Allahabad based barrister. Jawaharlal Nehru's mother's name was Swaroop Rani. Jawaharlal Nehru was the only son of Motilal Nehru. Motilal Nehru has three daughters apart from Jawaharlal Nehru. Nehrus were Saraswat Brahmin of Kashmiri lineage.

Jawaharlal Nehru received education in some of the finest schools and universities of the world. He did his schooling from Harrow and completed his Law degree from Trinity College, Cambridge. The seven years he spent in England widened his horizons and he acquired a rational and skeptical outlook and sampled Fabian socialism and Irish nationalism, which added to his own patriotic dedication.

Jawaharlal Nehru returned to India in 1912 and started legal practice. He married Kamala Nehru in 1916. Jawahar Lal Nehru joined Home Rule League in 1917. His real initiation into politics came two years later when he came in contact with Mahatma Gandhi in 1919. At that time Mahatma Gandhi had launched a campaign against Rowlatt Act. Nehru was instantly attracted to Gandhi's commitment for active but peaceful, civil disobedience. Gandhi himself saw promise and India's future in the young Jawaharlal Nehru.

Nehru family changed its family according to Mahatma Gandhi's teachings. Jawaharlal and Motilal Nehru abandoned western clothes and tastes for expensive possessions and pastimes. They now wore a Khadi Kurta and Gandhi cap. Jawaharlal Nehru took active part in the Non- Cooperation Movement 1920-1922) and was arrested for the first time during the movement. He was released after few months.

Jawaharlal Nehru was elected President of the Allahabad Municipal Corporation in 1924, and served for two years as the city's chief executive. This proved to be a valuable administrative experience for stood him in good stead later on when he became the prime minister of the country. He used his tenure to expand public education, health care and sanitation. He resigned in 1926 citing lack of cooperation from civil servants and obstruction from British authorities.

From 1926 to 1928, Jawaharlal served as the General Secretary of the All India Congress Committee. In 1928-29, the Congress's annual session under President Motilal Nehru was held. During that session Jawaharlal Nehru and Subhas Chandra Bose backed a call for full political independence, while Motilal Nehru and others wanted dominion status within the British Empire. To resolve the point, Gandhi said that the British would be given two years to grant India dominion status. If they did not, the Congress would launch a national struggle for full, political independence. Nehru and Bose reduced the time of opportunity to one year. The British did not respond.




In December 1929, Congress's annual session was held in Lahore and Jawaharlal Nehru was elected as the President of the Congress Party. During that sessions a resolution demanding India's independence was passed and on January 26, 1930 in Lahore, Jawaharlal Nehru unfurled free India's flag. Gandhiji gave a call for Civil Disobedience Movement in 1930. The movement was a great success and forced British Government to acknowledge the need for major political reforms.

When the British promulgated the Government of India Act 1935, the Congress Party decided to contest elections. Nehru stayed out of the elections, but campaigned vigorously nationwide for the party. The Congress formed governments in almost every province, and won the largest number of seats in the Central Assembly. Nehru was elected to the Congress presidency in 1936, 1937, and 1946, and came to occupy a position in the nationalist movement second only to that of Gandhi. Jawaharlal Nehru was arrested in 1942 during Quit India Movement. Released in 1945, he took a leading part in the negotiations that culminated in the emergence of the dominions of India and Pakistan in August 1947.

In 1947, he becamethe first Prime Minister of independent India. He effectively coped with the formidable challenges of those times: the disorders and mass exodus of minorities across the new border with Pakistan, the integration of 500-odd princely states into the Indian Union, the framing of a new constitution, and the establishment of the political and administrative infrastructure for a parliamentary democracy.

Jawaharlal Nehru played a key role in building modern India. He set up a Planning Commission, encouraged development of science and technology, and launched three successive five-year plans. His policies led to a sizable growth in agricultural and industrial production. Nehru also played a major role in developing independent India's foreign policy. He called for liquidation of colonialism in Asia and Africa and along with Tito and Nasser, was one of the chief architects of the nonaligned movement. He played a constructive, mediatory role in bringing the Korean War to an end and in resolving other international crises, such as those over the Suez Canal and the Congo, offering India's services for conciliation and international policing. He contributed behind the scenes toward the solution of several other explosive issues, such as those of West Berlin, Austria, and Laos.

But Jawahar Lal Nehru couldn't improve India's relations with Pakistan and China. The Kashmir issue proved a stumbling block in reaching an accord with Pakistan, and the border dispute prevented a resolution with China. The Chinese invasion in 1962, which Nehru failed to anticipate, came as a great blow to him and probably hastened his death. Jawaharlal Nehru died of a heart attack on May 27, 1964.

History Of Mac Os

Mac OS History

                           Apple
 


On January 24, 1984, Apple Computer, Inc. (now Apple Inc.) introduced the Macintosh personal computer, with the Macintosh 128K model, which came bundled with the Mac OS operating system, then known as the System Software. The Macintosh is often credited with popularizing the graphical user interface. The Mac OS has been pre-installed on almost every Macintosh computer ever sold. The operating system is also sold separately at Apple retail stores, and online. The original Mac OS was partially based on the Lisa OS, previously released by Apple for the Lisa computer in 1983 and, as part of an agreement allowing Xerox to buy shares in Apple at a favourable rate, it also used concepts from the Xerox PARC Xerox Alto which Steve Jobs and several other Macintosh team members had previewed.


    Early history

    Development

    The Macintosh project started in early 1979 with Jef Raskin, who envisioned an easy-to-use, low-cost computer for the average consumer. In September 1979, Raskin was given permission to start hiring for the project and was, in particular, looking for an engineer that could put together a prototype. Bill Atkinson, a member of the Apple Lisa team, introduced him to Burrell Smith, a service technician who had been hired earlier that year.
  In January 1981, Steve Jobs completely took over the Macintosh project. Jobs and a number of Apple engineers visited Xerox PARC in December 1979, three months after the Lisa and Macintosh projects had begun. After hearing about the pioneering GUI technology being developed at Xerox PARC from former Xerox employees like Raskin, Jobs negotiated a visit to see the Xerox Alto computer and Smalltalk development tools in exchange for Apple stock options. The final Lisa and Macintosh operating systems mostly used concepts from the Xerox Alto, but many elements of the graphical user interface were created by Apple including the menubar and pop-up menus.



    Unlike the IBM PC, which used 8 kB of system ROM for power-on self-test (POST) and basic input/output system (BIOS), the Mac ROM was significantly larger (64 kB) and held key OS code. Much of the original Mac ROM was coded by Andy Hertzfeld, a member of the original Macintosh team. He was able to conserve some of the precious ROM space by interleaving some of the assembly language code. In addition to coding the ROM, he also coded the kernel, the Macintosh Toolbox and some of the desktop accessories (DAs) as well. The icons of the operating system, which represented folders and application software were designed by Susan Kare, who later designed the icons for Microsoft Windows 3.0. Bruce Horn and Steve Capps wrote the Macintosh Finder as well as a number of Macintosh system utilities.




    Apple was very strong in advertising their newfound machine. After it was created, the company bought all 39 pages of advertisement space in the Newsweek magazine, 1984 November/December edition. Apple was so successful in its marketing for the Macintosh, that it quickly outshone its more sophisticated predecessor, the Lisa, in sales – so much so that Apple quickly developed a product called MacWorks which allowed the Lisa to emulate Macintosh system software through System 3, by which time it had been discontinued as the re-branded Macintosh XL. Many of Lisa's operating system advances would not appear in the Macintosh OS until System 7.
