MOTHER TERESA

Mother Teresa (26 August 1910 – 5 September 1997), born Agnesë Gonxhe Bojaxhiu was an Albanian Catholic nun with Indian citizenship who founded the Missionaries of Charity in Kolkata (Calcutta), India in 1950. For over 45 years she ministered to the poor, sick, orphaned, and dying, while guiding the Missionaries of Charity's expansion, first throughout India and then in other countries. Following her death she was beatified by Pope John Paul II and given the title Blessed Teresa of Calcutta.
By the 1970s, she was internationally famed as a humanitarian and advocate for the poor and helpless, due in part to a documentary and book Something Beautiful for God by Malcolm Muggeridge. She won the Nobel Peace Prize in 1979 and India's highest civilian honour, the Bharat Ratna, in 1980 for her humanitarian work. Mother Teresa's Missionaries of Charity continued to expand, and at the time of her death it was operating 610 missions in 123 countries, including hospices and homes for people with HIV/AIDS, leprosy and tuberculosis, soup kitchens, children's and family counselling programs, orphanages, and schools.
She has been praised by many individuals, governments and organizations; however, she has also faced a diverse range of criticism. These include objections by various individuals and groups, including Christopher Hitchens, Michael Parenti, Aroup Chatterjee, Vishva Hindu Parishad, against the proselytizing focus of her work including a strong stance against contraception and abortion, a belief in the spiritual goodness of poverty and alleged baptisms of the dying. Medical journals also criticised the standard of medical care in her hospices and concerns were raised about the opaque nature in which donated money was spent.

ALBERT EINSTIEN

Albert Einstein (14 March 1879–18 April 1955) was a theoretical physicist, philosopher and author who is widely regarded as one of the most influential and best known scientists and intellectuals of all time. He is often regarded as the father of modern physics. 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."
His many contributions to physics include the special and general theories of relativity, the founding of relativistic cosmology, the first post-Newtonian expansion, explaining the perihelion advance of Mercury, prediction of the deflection of light by gravity and gravitational lensing, the first fluctuation dissipation theorem which explained the Brownian movement of molecules, the photon theory and wave-particle duality, the quantum theory of atomic motion in solids, the zero-point energy concept, the semi classical version of the Schrödinger equation, and the quantum theory of a monatomic gas which predicted Bose–Einstein condensation.
Einstein published more than 300 scientific and over 150 non-scientific works. Einstein additionally wrote and commentated prolifically on numerous philosophical and political subjects.

MOHANDAS KARAMCHAND GANDHI

Mohandas Karamchand Gandhi (2 October 1869 – 30 January 1948) was the pre-eminent political and spiritual leader of India during the Indian independence movement. He was the pioneer of satyagraha—resistance to tyranny through mass civil disobedience, a philosophy firmly founded upon ahimsa or total nonviolence—which led India to independence and inspired movements for civil rights and freedom across the world. Gandhi is commonly known around the world as Mahatma Gandhi or "Great Soul", an honorific first applied to him by Rabindranath Tagore), and in India also as Bapu He is officially honoured in India as the Father of the Nation; his birthday, 2 October, is commemorated there as Gandhi Jayanti, a national holiday, and worldwide as the International Day of Non-Violence.
Gandhi first employed non-violent civil disobedience while an expatriate lawyer in South Africa, during the resident Indian community's struggle for civil rights. After his return to India in 1915, he organized protests by peasants, farmers, and urban labourers concerning excessive land-tax and discrimination. After assuming leadership of the Indian National Congress in 1921, Gandhi led nationwide campaigns to ease poverty, expand women's rights, build religious and ethnic amity, end untouchability, and increase economic self-reliance. Above all, he aimed to achieve Swaraj or the independence of India from foreign domination. Gandhi famously led his followers in the Non-cooperation movement that protested the British-imposed salt tax with the 400 km (240 mi) Dandi Salt March in 1930. Later, in 1942, he launched the Quit India civil disobedience movement demanding immediate independence for India. Gandhi spent a number of years in jail in both South Africa and India.
As a practitioner of ahimsa, he swore to speak the truth and advocated that others do the same. Gandhi lived modestly in a self-sufficient residential community and wore the traditional Indian dhoti and shawl, woven with yarn he had hand spun himself. He ate simple vegetarian food, eventually adopting a fruitarian diet, and also undertook long fasts as a means of both self-purification and social protest.

SIR ISAAC NEWTON

Sir Isaac Newton (4 January 1643 – 31 March 1727) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian who is considered by many scholars and members of the general public to be one of the most influential people in human history. His 1687 publication of the Philosophiæ Naturalis Principia Mathematica is considered to be among the most influential books in the history of science, laying the groundwork for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the scientific revolution.
Newton also built the first practical reflecting telescope and developed a theory of colour based on the observation that a prism decomposes white light into the many colours that form the visible spectrum. He also formulated an empirical law of cooling and studied the speed of sound
Newton remains uniquely influential to scientists, as demonstrated by a 2005 survey of members of Britain's Royal Society asking who had the greater effect on the history of science and had the greater contribution to humankind, Newton or Albert Einstein. Royal Society scientists deemed Newton to have made the greater overall contribution on both

26\11 MUBAI ATTACKS

The 2008 Mumbai attacks were more than ten coordinated shooting and bombing attacks across Mumbai, India's largest city, by Muslim terrorists from Pakistan. The attacks, which drew widespread condemnation across the world, began on 26 November 2008 and lasted until 29 November, killing at least 173 people and wounding at least 308.

Eight of the attacks occurred in South Mumbai: at Chhatrapati Shivaji Terminus, the Oberoi Trident, the Taj Mahal Palace & Tower, Leopold Cafe, Cama Hospital (a women and children's hospital), the Orthodox Jewish-owned Nariman House,the Metro Cinema,[11] and a lane behind the Times of India building and St. Xavier's College. There was also an explosion at Mazagaon, in Mumbai's port area, and in a taxi at Vile Parle. By the early morning of 28 November, all sites except for the Taj hotel had been secured by Mumbai Police and security forces. An action by India's National Security Guards (NSG) on 29 November (the action is officially named Operation Black Tornado) resulted in the death of the last remaining attackers at the Taj hotel, ending all fighting in the attacks.

Ajmal Kasab, the only attacker who was captured alive, disclosed that the attackers were members of Lashkar-e-Taiba, the Pakistan-based militant organization, considered a terrorist organization by India, the United States, and the United Kingdom, among others. The Indian Government said that the attackers came from Pakistan, and their controllers were in Pakistan.

On 7 January 2009, after more than a month of denying the nationality of the attackers, Pakistan's Information Minister Sherry Rehman officially accepted Ajmal Kasab's nationality as Pakistani. On 12 February 2009, Pakistan's Interior Minister Rehman Malik, in a televised news briefing, confirmed that parts of the attack had been planned in Pakistan and said that six people, including the alleged mastermind, were being held in connection with the attacks.

RAIDITION

In physics, radiation describes any process in which energy travels through a medium or through space, ultimately to be absorbed by another body. Non-physicists often associate the word with ionizing radiation (e.g., as occurring in nuclear weapons, nuclear reactors, and radioactive substances), but it can also refer to electromagnetic radiation (i.e., radio waves, infrared light, visible light, ultraviolet light, and X-rays) which can also be ionizing radiation, to acoustic radiation, or to other more obscure processes. What makes it radiation is that the energy radiates (i.e., it travels outward in straight lines in all directions) from the source. This geometry naturally leads to a system of measurements and physical units that are equally applicable to all types of radiation. Some radiations can be hazardous.

THE DIFFERENT TYPES OF RAIDIATIONS
Alpha radiation

Alpha (α) decay is a method of decay in large nuclei. An alpha particle (helium nucleus, He2+), consisting of 2 neutrons and 2 protons, is emitted. Because of the particle's relatively high charge, it is heavily ionizing and will cause severe damage if ingested. However, due to the high mass of the particle, it has little energy and a low range; typically alpha particles can be stopped with a sheet of paper (or skin).




Beta(+/-) radiation

Beta-minus (β-) radiation consists of an energetic electron. It is less ionizing than alpha radiation, but more than gamma. The electrons can often be stopped with a few centimeters of metal. It occurs when a neutron decays into a proton in a nucleus, releasing the beta particle and an antineutrino.

Beta-plus (β+) radiation is the emission of positrons. Because these are antimatter particles, they annihilate any matter nearby, releasing gamma photons.

Gamma radiation

Gamma (γ) radiation consists of photons with a frequency of greater than 1019 Hz[1]. Gamma radiation occurs to rid the decaying nucleus of excess energy after it has emitted either alpha or beta radiation.

HISTORY OF THE LEAGUE OF NATIONS

Following in the wake of the failed League of Nations (1919–1946), which the United States never joined, the United Nations was established in 1945 to maintain international peace and promote cooperation in solving international economic, social and humanitarian problems. The earliest concrete plan for a new world organization was begun under the aegis of the U.S. State Department in 1939. Franklin D. Roosevelt first coined the term 'United Nations' as a term to describe the Allied countries. The term was first officially used on 1 January 1942 when 26 governments signed the Atlantic Charter, pledging to continue the war effort. On 25 April 1945, the UN Conference on International Organization began in San Francisco, attended by 50 governments and a number of non-governmental organizations involved in drafting the Charter of the United Nations. The UN officially came into existence on 24 October 1945 upon ratification of the Charter by the five permanent members of the Security Council—France, the Republic of China, the Soviet Union, the United Kingdom and the United States—and by a majority of the other 46 signatories. The first meetings of the General Assembly, with 51 nations represented, and the Security Council, took place in Westminster Central Hall in London in January 1946.

Since its creation, there has been controversy and criticism of the UN organization. In the United States, an early opponent of the UN was the John Birch Society, which began a "get US out of the UN" campaign in 1959, charging that the UN's aim was to establish a "One World Government." After the Second World War, the French Committee of National Liberation was late to be recognized by the US as the government of France, and so the country was initially excluded from the conferences that aimed at creating the new organization. Charles de Gaulle criticized the UN, famously calling it le machin ("the thingie"), and was not convinced that a global security alliance would help maintaining world peace, preferring direct defence treaties between countries.
