JESUS CHRIST


J E S U S





Jesus Christ, also known as Jesus of Nazareth, is a Jewish teacheHe said that one must be mild and reformer of religion who has become the central figure of Christianity. Christians follow the example of Jesus, accept his words to be true, and worship him as God. He is one of the most famous, most recognized, and most influential persons in the history of the world.

Most historians agree that he was a Jew from a place called Judea, in a town called Nazareth, in what is now Israel. They also agree that he was thought of as a teacher and a healer, and that he was baptized by John the Baptist. He was crucified in Jerusalem on the orders of Pontius Pilate. The Quran claims that Jesus was a Muslim.








Jesus taught mainly love and forgiveness for others, as well as being humble about one's religion. He said that one must be mild, like a child, and never boast. He taught that people who ignore God and other people do not deserve his blessing, but God would still forgive them if they repented. Jesus opposed the other Jewish priests because they used religion to boast. This led to other Jewish leaders hating Jesus, because Jesus was trying to stop them. Jesus also opposed human authority, leading to the Roman authorities executing him because of his threat to their power.


There are stories about the life of Jesus by different writers. The best known are the four Christian books called the Gospels. They form the beginning of the New Testament, a part of the Bible. The word "gospel" means "good news". They tell a little about his birth and hidden early life, but mostly about his public life: his teachings, miracles, ministry, death, and "resurrection" (return from death). The four Gospels are named after their respective writers: Matthew, Mark, Luke, and John.

Several Jewish and Roman historians, such as Flavius Josephus, Tacitus, Pliny the Younger, and Suetonius include Jesus in their writings. They usually only tell of his execution or problems between the Roman government and his followers; they do not talk about his life, since his life was not a problem they had with Jesus.

CHARLES BABBAGE



CHARLES BABBAGE

Charles Babbage (26 December 179118 October 1871) was an English mathematician, analytical philosopher, mechanical engineer and computer scientist. He was the first person to come up with the idea of a computer that could be programmed. Unfinished parts of his mechanisms are on display in the London Science Museum.
Charles Babbage was born in England, at 44 Crosby Row, Walworth Road, London. Babbage's father, Benjamin Babbage, was a banker in London who owned the Bitton Estate in Teignmouth. His mother was Betsy Plumleigh Babbage. In 1808, the Babbage family moved into the old Rowdens house in East Teignmouth.
His Brain is also on display in the Science Museum in London.

Works

Knowing that there were lots of errors in the calculation of mathematical tables, Babbage wanted to find a method by which they could be calculated mechanically, removing errors made by humans. Three different factors seem to have influenced him: a dislike of untidiness; his experience working on logarithmic tables; and existing work on calculating machines carried out by Wilhelm Schickard, Blaise Pascal, and Gottfried Leibniz. He first talked about the principles of a calculating engine in a letter to Sir Humphrey Davy in 1822.


Part of Babbage's difference engine, assembled after his death by Babbage's son, using parts found in his laboratory.
Babbage's engines were among the first mechanical computers. His engines were not actually completed because he did not have enough money. Babbage realised that a machine could do the work better and more reliably than a human being. Babbage controlled building of some steam-powered machines that more or less did their job; calculations could be mechanized to an extent. Although Babbage's machines were large machines they were organized in a way similar to modern computer architecture. The data and program memory were separated, operation was instruction based, control unit could make conditional jumps and the machine had a separate I/O unit. Ada Lovelace studied how to program them.

HISTORY OF INDIA



HISTORY OF INDIA

The HISTORY OF INDIA includes the prehistoric settlements and societies in the Indian subcontinent; the advancement of civilisation from the Indus Valley Civilisation to the eventual blending of the Indo-Aryan culture to form the Vedic Civilisation; the rise of Hinduism, Jainism and Buddhism; the onset of a succession of powerful dynasties and empires for more than three millennia throughout various geographic areas of the subcontinent, including the growth of Muslim dominions during the Medieval period intertwined with Hindu powers; the advent of European traders and privateers, resulting in the establishment of British India; and the subsequent independence movement that led to the Partition of India and the creation of the Republic of India. 





Considered a cradle of civilisation, the Indus Valley Civilisation, which spread and flourished in the north-western part of the Indian subcontinent from 3300 to 1300 BCE, was the first major civilisation in South Asia. A sophisticated and technologically advanced urban culture developed in the Mature Harappan period, from 2600 to 1900 BCE. This civilisation collapsed at the start of the second millennium BCE and was later followed by the Iron Age Vedic Civilisation. The era saw the composition of the Vedas, the seminal texts of Hinduism, coalesce into Janapadas (monarchical, state-level polities), and social stratification based on caste. The Later Vedic Civilisation extended over the Indo-Gangetic plain and much of the subcontinent, as well as witnessed the rise of major polities known as the Mahajanapadas. In one of these kingdoms, Magadha, Gautama Buddha and Mahavira propagated their Shramanic philosophies during the fifth and sixth century BCE.






Most of the Indian subcontinent was conquered by the Maurya Empire during the 4th and 3rd centuries BCE. From the 3rd century BCE onwards Prakrit and Pali literature in the north and the Tamil Sangam literature in southern India started to flourish. Wootz steel originated in south India in the 3rd century BCE and was exported to foreign countries. During the Classical period, various parts of India were ruled by numerous dynasties for the next 1,500 years, among which the Gupta Empire stands out. This period, witnessing a Hindu religious and intellectual resurgence, is known as the classical or "Golden Age of India". During this period, aspects of Indian civilisation, administration, culture, and religion (Hinduism and Buddhism) spread to much of Asia, while kingdoms in southern India had maritime business links with the Middle East and the Mediterranean. Indian cultural influence spread over many parts of Southeast Asia which led to the establishment of Indianised kingdoms in Southeast Asia (Greater India).
  
The most significant event between the 7th and 11th century was the Tripartite struggle centred on Kannauj that lasted for more than two centuries between the Pala Empire, Rashtrakuta Empire, and Gurjara Pratihara Empire. Southern India saw the rise of multiple imperial powers from the middle of the fifth century, most notable being the Chalukya, Chola, Pallava, Chera, Pandyan, and Western Chalukya Empires. The Chola dynasty conquered southern India and successfully invaded parts of Southeast Asia, Sri Lanka, Maldives and Bengalin the 11th century. The early medieval period Indian mathematics influenced the development of mathematics and astronomy in the Arab world and the Hindu numerals were introduced.






Muslim rule started in parts of north India in the 13th century when the Delhi Sultanate was founded in 1206 CE by Central Asian Turks; though earlier Muslim conquests made limited inroads into modern Afghanistan and Pakistan as early as the 8th century. The Delhi Sultanate ruled the major part of northern India in the early 14th century, but declined in the late 14th century. This period also saw the emergence of several powerful Hindu states, notably Vijayanagara, Gajapati, Ahom, as well as Rajput states, such as Mewar. The 15th century saw the creation of Sikhism. The early modern period began in the 16th century, when the Mughals conquered most of the Indian subcontinent. 


The Mughals suffered a gradual decline in the early 18th century, which provided opportunities for the Marathas, Sikhs and Mysoreans to exercise control over large areas of the subcontinent.

From the late 18th century to the mid-19th century, large areas of India were annexed by the British East India Company of the British Empire. Dissatisfaction with Company rule led to the Indian Rebellion of 1857, after which the British provinces of India were directly administered by the British Crown and witnessed a period of rapid development of infrastructure, economic decline and major famines. During the first half of the 20th century, a nationwide struggle for independence was launched with the leading party involved being the Indian National Congress which was later joined by other organisations. The subcontinent gained independence from the United Kingdom in 1947, after the British provinces were partitioned into the dominions of India and Pakistan and the princely states all acceded to one of the new states.






REPUBLIC OF INDIA




On 15 August 1947, British Indian Empire was partitioned into two countries, India (Hindustan) and Pakistan. With this the British Raj in the Indian subcontinent ended. On 26 January 1950, Hindustan adopted a constitution. From that day, Hindustanis became the Republic of India or Indians.
During last 60 years, Republic of India has seen different stages in its national life. Some of them are as follows:
  • It fought three wars against Pakistan, and one war against China. Wars with Pakistan were fought in 1947, 1965, and 1971. In 1999, it had a limited skirmish in Kargil. The war with China was fought in 1962. In 1971, the Republic of India also helped Bangladesh in its freedom struggle.
  • Under the leadership of Jawaharlal Nehru (the first Prime Minister of India), India had adopted a socialist economy. Some economists think it was a mixed economy. In a mixed economy, socialism and capitalism continue together. During this period, lasting for several years up to end-1980s, India could rapidly develop its infrastructure, science and technology.
  • By the early 1990s, India had changed its economic policies. It started several reforms to attract more capital from other countries. Local businessmen and industrialists also got more freedom to carry out their activities.
  • In 1974, India had already detonated its first nuclear bomb. It repeated the same in 1998. With this, it became a nuclear power.
Presently (As of 2006), India is currently the tenth largest economy in terms of gross GDP. It is the 4th largest economy of the world when accounting for purchasing power parity. Some economists think that in coming decades, India’s economy will become still larger.
