Avul pakir hainulabdeen abdul kalam was born on 15 OCTOBER 1931 to Tamil Muslimfamily in the pilgrimage centre of Rameswaram on pamban island ,then in the Madras presidency and now in the state of Tamil Nadu.His father jainulabudeen was a boat owner and imamof a local mosque;his mother ashiamma was a housewife .His father owned a ferry that took Hindhupligrims back and forth between RAMESWARAM and the now uninhabited DHANUSHKODI . kalam was the yougest of four brothers and one sister in his family.His ancestors had been wealthy traders and landowners ,with numerus properties and large tracts of land. Their business had involved trading groceries between the mainland and the island and to and from SRILANKA ,as well as ferrying poligrims betweenthe maintained and pamban.As a result ,the family acquired the title of "Mara kalam iyakkivar"(wooden boat steeres),which over the years became shortened to "Marakier" with the opening of thePAMBAN BRIDGEto the mainland in 1914 however,the businesses failed and the family fortune and properies were lost over time,apart from the ancestral home. By his early childhood ,kalam'sfamily gad become poor; at an early age,he sold newspapers to supplement his family's income.
In his school years,kalam had average grades but was described as a bright and hardworking student who had a strong desire to learn.He spent hours on his studies, espcially mathematics.After completing his education at the schwartz highersecondary school,Ramanathapuram,kalam went on to attend SAINT JOSEPH'S COLLEGE,TIRUCHIRAPPALLI then affiliated with the UNIVERSITY OF MADRAS ,from where he graduated in PHYSICS in 1954.He moved to MADRAS om 1995 to study aerospace engineering in MADRAS INSTITUTE OF TECHNOLOGY. while kalm was workin on a senir class project the dean was dissarisfied with his lack of progress and threatened to rvoke his scholarship unless the prohect was finished within the next three days.Kalam met the deadline,impressing the dean,who later said to him,"I Was putting you under stress and asking you to meet a difficult deadline . He narrowly missed achieving his dream of becoming a fighter pilot,as he placed 9nth in qualifiers,and only eight positions were available inthe IAF.
This was my first stage, in which I learnt leadership from three great teachers—Dr Vikram Sarabhai , Prof Satish Dhawan and Dr Brahm Prakash. This was the time of learning and acquisition of knowledge for me.
After graduating from the Madras Institute of Technology in 1960, Kalam joined the Aeronautical Development Establishment of the Defence Research and Development Organisation (DRDO) as a scientist after becoming a member of the Defence Research & Development Service (DRDS). He started his career by designing a small hovercraft, but remained unconvinced by his choice of a job at DRDO. Kalam was also part of the INCOSPAR committee working under Vikram Sarabhai, the renowned space scientist. In 1969, Kalam was transferred to the Indian Space Research Organisation (ISRO) where he was the project director of India's first Satellite Launch Vehicle (SLV-III) which successfully deployed the Rohini satellite in near-earth orbit in July 1980; Kalam had first started work on an expandable rocket project independently at DRDO in 1965.In 1969, Kalam received the government's approval and expanded the programme to include more engineers.
In 1963 to 1964, he visited NASA's Langley Research Center in Hampton, Virginia; Goddard Space Flight Center in Greenbelt, Maryland; and Wallops Flight Facility. Between the 1970s and 1990s, Kalam made an effort to develop the Polar Satellite Launch Vehicle (PSLV) and SLV-III projects, both of which proved to be successful.
Kalam was invited by Raja Ramanna to witness the country's first nuclear test Smiling Buddha as the representative of TBRL, even though he had not participated in its development. In the 1970s, Kalam also directed two projects, Project Devil and Project Valiant, which sought to develop ballistic missiles from the technology of the successful SLV programme. Despite the disapproval of the Union Cabinet, Prime Minister Indira Gandhi allotted secret funds for these aerospace projects through her discretionary powers under Kalam's directorship. Kalam played an integral role convincing the Union Cabinet to conceal the true nature of these classified aerospace projects. His research and educational leadership brought him great laurels and prestige in the 1980s, which prompted the government to initiate an advanced missile programme under his directorship. Kalam and Dr V S Arunachalam, metallurgist and scientific adviser to the Defence Minister, worked on the suggestion by the then Defence Minister, R. Venkataraman on a proposal for simultaneous development of a quiver of missiles instead of taking planned missiles one after another.R Venkatraman was instrumental in getting the cabinet approval for allocating ₹388 crores for the mission, named Integrated Guided Missile Development Programme (IGMDP) and appointed Kalam as the chief executive. Kalam played a major part in developing many missiles under the mission including Agni, an intermediate range ballistic missile and Prithvi, the tactical surface-to-surface missile, although the projects have been criticised for mismanagement and cost and time overruns.
Kalam served as the Chief Scientific Adviser to the Prime Minister and Secretary of the Defence Research and Development Organisation from July 1992 to December 1999. The Pokhran-II nuclear tests were conducted during this period in which he played an intensive political and technological role. Kalam served as the Chief Project Coordinator, along with Rajagopala Chidambaram, during the testing phase. Media coverage of Kalam during this period made him the country's best known nuclear scientist. However, the director of the site test, K Santhanam, said that the thermonuclear bomb had been a "fizzle" and criticisied Kalam for issuing an incorrect report. Both Kalam and Chidambaram dismissed the claims.
In 1998, along with cardiologist Soma Raju, Kalam developed a low cost coronary stent, named the "Kalam-Raju Stent". In 2012, the duo designed a rugged tablet computer for health care in rural areas, which was named the "Kalam-Raju Tablet".
Kalam was the youngest of five siblings, the eldest of whom was a sister, Asim Zohra (d. 1997), followed by three elder brothers: Mohammed Muthu Meera Lebbai Maraikayar (b. 1916; aged 99), Mustafa Kamal (d. 1999) and Kasim Mohammed (d. 1995). He was extremely close to his elder siblings and their extended families throughout his life, and would regularly send small sums of money to his older relations, himself remaining a lifelong bachelor.
MAHATHMA GANDHI was the leader of the Indian independence movement against British rule. Employing nonviolent civil disobedience, Gandhi led India to independence and inspired movements for civil rights and freedom across the world. The honorific Mahātmā (Sanskrit: "high-souled", "venerable")—applied to him first in 1914 in South Africa —is now used worldwide. In India, he is also called Bapu (Gujarati: endearment for "father", "papa" and Gandhiji. He is unofficially called the Father of the Nation.
Born and raised in a Hindu merchant caste family in coastal Gujarat, western India, and trained in law at the Inner Temple, London, Gandhi first employed nonviolent civil disobedience as an expatriate lawyer in South Africa, in the resident Indian community's struggle for civil rights. After his return to India in 1915, he set about organising peasants, farmers, and urban labourers to protest against excessive land-tax and discrimination. Assuming leadership of the Indian National Congress in 1921, Gandhi led nationwide campaigns for easing poverty, expanding women's rights, building religious and ethnic amity, ending untouchability, but above all for achieving Swaraj or self-rule.
Gandhi famously led Indians in challenging the British-imposed salt tax with the 400 km (250 mi) Dandi Salt March in 1930, and later in calling for the British to Quit India in 1942. He was imprisoned for many years, upon many occasions, in both South Africa and India. Gandhi attempted to practice nonviolence and truth in all situations, and advocated that others do the same. He lived modestly in a self-sufficient residential community and wore the traditional Indian dhoti and shawl, woven with yarn hand-spun on a charkha. He ate simple vegetarian food, and also undertook long fasts as a means of both self-purification and social protest.
Gandhi's vision of an independent India based on religious pluralism, however, was challenged in the early 1940s by a new Muslim nationalism which was demanding a separate Muslim homeland carved out of India. Eventually, in August 1947, Britain granted independence, but the British Indian Empire was partitioned into two dominions, a Hindu-majority India and Muslim-majority Pakistan. As many displaced Hindus, Muslims, and Sikhs made their way to their new lands, religious violence broke out, especially in the Punjab and Bengal. Eschewing the official celebration of independence in Delhi, Gandhi visited the affected areas, attempting to provide solace. In the months following, he undertook several fasts unto death to promote religious harmony. The last of these, undertaken on 12 January 1948 when he was 78, also had the indirect goal of pressuring India to pay out some cash assets owed to Pakistan. Some Indians thought Gandhi was too accommodating. Among them was Nathuram Godse, a Hindu nationalist, who assassinated Gandhi on 30 January 1948 by firing three bullets into his chest.
Mahatma Gandhi's birthday, 2 October, is commemorated in India as Gandhi Jayanti, a national holiday, and worldwide as the International Day of Nonviolence.
Swami vivekananda born Narendranath Datta (Bengali), was an Indian Hindu monk, a chief disciple of the 19th-century Indian mystic Ramakrishna. He was a key figure in the introduction of the Indian philosophies of Vedanta and Yoga to the Western world and is credited with raising interfaith awareness, bringing Hinduism to the status of a major world religion during the late 19th century. He was a major force in the revival of Hinduism in India, and contributed to the concept of nationalism in colonial India.Vivekananda founded the Ramakrishna Math and the Ramakrishna Mission. He is perhaps best known for his speech which began, "Sisters and brothers of America ...," in which he introduced Hinduism at the Parliament of the World's Religions in Chicago in 1893.
Born into an aristocratic Bengali family of Calcutta, Vivekananda was inclined towards spirituality. He was influenced by his Guru, Ramakrishna Deva, from whom he learnt that all living beings were an embodiment of the divine self; therefore, service to God could be rendered by service to mankind. After Ramakrishna's death, Vivekananda toured the Indian subcontinent extensively and acquired first-hand knowledge of the conditions prevailing in British India. He later travelled to the United States, representing India at the 1893 Parliament of the World Religions. Vivekananda conducted hundreds of public and private lectures and classes, disseminating tenets of Hindu philosophy in the United States, England and Europe. In India, Vivekananda is regarded as a patriotic saint and his birthday is celebrated there as National Youth Day.
Alber einsteein was a German-born theoretical physicist. He developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).Einstein's work is also known for its influence on the philosophy of science. Einstein is best known by the general public 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", a pivotal step in the evolution of 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 him to develop his special theory of relativity during his time at the Swiss Patent Office in Bern (1902–1909) , Switzerland. 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 general 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.
Between 1895 and 1914 he lived in Switzerland (except for one year in Prague, 1911–12), where he received his academic diploma from the Swiss Federal Polytechnic in Zürich (later the Eidgenössische Technische Hochschule, ETH) in 1900. He later taught there at the same institute as a professor of theoretical physics between 1912 and 1914 before he left for Berlin. In 1901, after being stateless for more than five years, Einstein acquired Swiss citizenship, which he kept for the rest of his life. In 1905, Einstein was awarded a PhD by the University of Zürich. The same year, his annus mirabilis (miracle year), he published four groundbreaking papers, which were to bring him to the notice of the academic world, at the age of 26.
He was visiting the United States when Adolf Hitler came to power in 1933 and, being Jewish, did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the United States, 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 development 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 supported defending the Allied forces, but generally denounced the idea of using the newly discovered 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. Einstein's intellectual achievements and originality have made the word "Einstein" synonymous with "genius".
