Anna Hazare Biography

  • Kisan Bapat Baburao Hazare known as Anna Hazare.His date of birth is on 15 January 1940.Anna Hazare was born in Bhingar village in Ahmednagar district of Maharashtra state in western India to Baburao Hazare and Laxmi Bai, an unskilled labourer family.He was raised by his childless aunt in Mumbai but could not continue beyond VII standard and had to quit midway due to problems.He has two sisters.He is unmarried.Anna Hazare started his career as a driver in the Indian Army.During his 15-year tenure as a soldier, he was posted to several states like Sikkim, Bhutan, Jammu-Kashmir, Assam, Mizoram, Leh and Ladakh and braved challenging weathers.Anna was greatly influenced by Swami Vivekananda’s teachings.In the year 1965, Pakistan attacked India and at that time, Hazare was posted at the Khemkaran border. On November 12, 1965, Pakistan launched air attacks on Indian base and all of Hazare’s comrades became martyrs.In 1978, he took voluntary retirement from the 9th Maratha Battalion.After serving 15 Years in Army Anna took the voluntary retirement and returned to his native place in Ralegan Siddhi, in the Parner tehsil of Ahmednagar district.Ralegan Siddhi falls in the drought-prone area with a mere 400 to 500 mm of annual rainfall.There were no weirs to retain rainwater.During the month of April and May, water tankers were the only means of drinking water.Almost 80 per cent of the villagers were dependent on other villages for food grains. Residents used to walk for more than four to six kilometers in search of work.Hazare came across the work of one Vilasrao Salunke, a resident of Saswad near Pune who had started a novel project of water management through watershed development in a joint venture with the Gram Panchyat. Hazare visited the project and decided to implement it in Ralegan Siddhi.He steered the villagers to begin working towards water conservation.At the outset, they completed 48 Nala Bunding work, contour trenches, staggered trenches, gully plugs, meadows development and of forestation of 500 hectares of land. Thereafter, they constructed five RCC weirs and 16 Gabion Weirs.This resulted in increase in the ground water level.Hazare’s Ralegan Siddhi became the first role model of an ideal village from the worst village to an ideal village.Anna rightly thought that Development is marred by corruption and started a new venture in 1991 called Bhrashtachar Virodhi Jan Aandolan (BVJA) or public movement against corruption.It was found that some 42 forest officers had duped the state government for crores of rupees through corruption in confederacy.Hazare submitted the evidences to the government but the latter was reluctant to take action against all these officers as one of the ministers of the ruling party was involved in the scam.A distressed Hazare returned the Padmashree Award to the President of India and also returned the Vriksha Mitra Award given by then prime minister of India Rajiv Gandhi.He further went on an indefinite hunger strike in Alandi on the same issue.Finally, the government woke up and took action against the criminal and corrupt officers as well as six of the ministers were forced to resign and more than 400 officers from different government offices were sent back to home.In 1995 Shiv Sena-BJP government came to power in the state
  • Hazare raised the issue of alleged massive land purchase by Gholap's wife Shashikala in Nashik between April to September 1996.He forwarded the available documentary evidences in support of his allegations to then Maharashtra Governor P. C. Alexander .On 4 November 1997, Gholap filed a defamation suit against Hazare for accusing him of corruption.On 9 September 1998, Anna Hazare was imprisoned in the Yerawada Jail after being sentenced to simple imprisonment for three months by the Mumbai Metropolitan Court all political parties, every one from Maharashtra except the BJP and the Shiv Sena came in support of him.Later due to public protest, outcry the Government of Maharashtra ordered his release from the jail.The state government has opened cooperative societies, credit societies & urban banks everywhere in states.However, the directors of such societies do the corruption and failed to pay back the basic amount to the members of the societies.Thus poor people get cheated when Anna saw this he again began his agitation against this.Hazare agitated for over eight months.The result was that more than Rs 125 crore was recovered from defaulters and the members of such societies heaved a sigh of relief.Recovery of around Rs. 400 crores is in the pipeline.After this Anna started to fight for the Right to information act.Government ignored Anna.In 1997 Anna agitated in Azad Maidan in Mumbai to create mass public awareness about RTI amongst the youth.
  • Anna started to travel across state.Government promised Anna they will pass RTI act but in reality they never did it.For this Anna agitated ten times for this law.When Anna saw that Government is not willing to pass this law Anna went on an indefinite hunger strike at Azad Maidan in the last week of July 2003.After 12 days of Hunger strike in Azad Maidan the President of India signed the draft of the Right to Information Act and ordered the state government to implement it with effect from 2002. The same draft was considered as the base document for the making of the National Right to Information Act-2005.In 2003 Anna Hazare raised corruption charges against 4 ministers of the Congress-NCP government Government ignored him Then Anna started his fast unto death agitation on 9 August 2003.He ended his fast on 17 August 2003 after then chief minister Sushil Kumar Shinde formed a one man commission, headed by the retired justice P. B. Sawant to probe his charges.The P. B. Sawant commission report was submitted on 23 February 2005, indicted Suresh Jain, Nawab Malik and Padmasinh Patil.Suresh Jain and Nawab Malik resigned from the cabinet in March 2005.Jan Lokpal Bill:Agitation and hunger strike at the age of 73 and great victory against powerful and rich government India against corruption movement N. Santosh Hegde, a former justice of the Supreme Court of India and Lokayukta of Karnataka, Prashant Bhushan, a senior lawyer in the Supreme Court along with the members of the India against Corruption movement drafted an alternate bill, named as the Jan Lokpal Bill (People's Ombudsman Bill) with more stringent provisions and wider power to the Lokpal (Ombudsman) .On April 5 2011 Again Anna started second freedom struggle in India.Anna wrote to everyone regarding Jan Lok Pal bill but no one listened him .After that on 5th April 2011 Started fast unto death to wake up the government for India.Anna started war against corruption in India.Hazare has started a fast unto death from 5 April 2011 at Jantar Mantar in Delhi, to press for the demand to form a joint committee of the representatives of the Government and the civil society to draft a new bill with stronger penal actions and more independence to the Lokpal and Lokayuktas (Ombudsmen in the states).In beginning Government of India ignored him, many people said many things, but as First day was over Anna got the support from every corner of India and No one has expected such a support Anna will get for this bill.Over night table were turned and after 4 days of discussion with government of India servants .Finally Prime Minister of India Manmohan Singh realized that demand of Anna is right and government accepted all the demands of Anna.Thus Jantar Mantar saved from becoming another Tahir Square.Anna Hazare won the following awards –
  • Indira Priyadarshini Vrikshamitra award by the Government of India on November 19, 1986 from the hands of Prime Minister of India Rajiv Gandhi.
  • 1989 - Krishi Bhushana award by the Government of Maharashtra.
  • 1990 - Padmashri award, by the Government of India
  • 1992 - Padmabhushan award, by the Government of India
  • 2008 - On April 15 2008, Anna Hazare received the World Bank's 2008 Jit Gill Memorial Award for Outstanding Public Service
  • Care International of the USA, Transparency International, Seoul (South Korea)
  • He received awards worth Rs 25 lakh and donated the entire amount for the Swami Vivekananda Kritadnyata Nidhi (social gratitude fund). Out of the two lakh rupees received from the above amount, mass marriages are carried of at least 25-30 poor couples every year.Anna Hazare has given his life for the benefit of India.He got the home in his village but he has not entered in that house from last 35 years.Anna Hazare has declared he has got Rs68, 688 in bank balance and cash and three pieces of land Hazare's lands were either donated to him or family owned .In his statement, Hazare said two land pieces measuring 0.07 Hectares and two hectares are in his native village in Ralegan Siddhi in Maharashtra while 0.46 hectare of land is in Pimpianer.One of the pieces of land in Ralegan Siddhi was donated by Army to him which he has donated for village use the Pimpianer land was donated to him by a villager.Hazare has further donated this land for village use.Anna Hazare never got any grant from Government of India.

Acharya Patanjali,Father of Yoga

The Science of Yoga is one of several unique contributions of India to the world. It seeks to discover and realize the ultimate Reality through yogic practices. Acharya Patanjali, the founder, hailed from the district of Gonda (Ganara) in Uttar Pradesh. He prescribed the control of prana (life breath) as the means to control the body, mind and soul. This subsequently rewards one with good health and inner happiness. Acharya Patanjali's 84 yogic postures effectively enhance the efficiency of the respiratory, circulatory, nervous, digestive and endocrine systems and many other organs of the body. Yoga has eight limbs where Acharya Patanjali shows the attainment of the ultimate bliss of God in samadhi through the disciplines of: yam, niyam, asan, pranayam, pratyahar, dhyan and dharna. The Science of Yoga has gained popularity because of its scientific approach and benefits. Yoga also holds the honored place as one of six philosophies in the Indian philosophical system. Acharya Patanjali will forever be remembered and revered as a pioneer in the science of self-discipline, happiness and self realisation.

Acharya kapil,Father of cosmology

Celebrated as the founder of sankhya philosophy, acharya kapil is believed to have beeen born in BCE 3000 to the illustrious sage kardam and devhuti.He gifted the world with sankhya school of thought.His pioneer work threw light on the nature and principles of the ultimate Soul (Purusha), primal matter (Prakruti) and creation. His concept of transformation of energy and profound commentaries on atma, non-atma and the subtle elements of the cosmos places him in an elite class of master achievers - incomparable to the discoveries of other cosmologists. On his assertion that Prakruti, with the inspiration of Purusha, is the mother of cosmic creation and all energies, he contributed a new chapter in the science of cosmology. Because of his extrasensory observations and revelations on the secrets of creation, he is recognized and saluted as the Father of Cosmology

Acharya Kanad,Founder of Atomic Theory

As the founder of "Vaisheshik Darshan"- one of six principal philosophies of India - Acharya Kanad was a genius in philosophy. He is believed to have been born in Prabhas Kshetra near Dwarika in Gujarat. He was the pioneer expounder of realism, law of causation and the atomic theory. He has classified all the objects of creation into nine elements, namely: earth, water, light, wind, ether, time, space, mind and soul. He says, "Every object of creation is made of atoms which in turn connect with each other to form molecules." His statement ushered in the Atomic Theory for the first time ever in the world, nearly 2500 years before John Dalton. Kanad has also described the dimension and motion of atoms and their chemical reactions with each other. The eminent historian, T.N. Colebrook, has said, "Compared to the scientists of Europe, Kanad and other Indian scientists were the global masters of this field."

Acharya Sushrut,Father of plastic surgery

A genius who has been glowingly recognized in the annals of medical science. Born to sage Vishwamitra, Acharya Sudhrut details the first ever surgery procedures in "Sushrut Samhita," a unique encyclopedia of surgery. He is venerated as the father of plastic surgery and the science of anesthesia. When surgery was in its infancy in Europe, Sushrut was performing Rhinoplasty (restoration of a damaged nose) and other challenging operations. In the "Sushrut Samhita," he prescribes treatment for twelve types of fractures and six types of dislocations. His details on human embryology are simply amazing. Sushrut used 125 types of surgical instruments including scalpels, lancets, needles, Cathers and rectal speculums; mostly designed from the jaws of animals and birds. He has also described a number of stitching methods; the use of horse's hair as thread and fibers of bark. In the "Sushrut Samhita," and fibers of bark. In the "Sushrut Samhita," he details 300 types of operations. The ancient Indians were the pioneers in amputation, caesarian and cranial surgeries. Acharya Sushrut was a giant in the arena of medical science.

ACHARYA CHARAK

Acharya Charak has been crowned as the Father of Medicine. His renowned work, the "Charak Samhita", is considered as an encyclopedia of Ayurveda. His principles, diagoneses, and cures retain their potency and truth even after a couple of millennia. When the science of anatomy was confused with different theories in Europe, Acharya Charak revealed through his innate genius and enquiries the facts on human anatomy, embryology, pharmacology, blood circulation and diseases like diabetes, tuberculosis, heart disease, etc. In the "Charak Samhita" he has described the medicinal qualities and functions of 100,000 herbal plants. He has emphasized the influence of diet and activity on mind and body. He has proved the correlation of spirituality and physical health contributed greatly to diagnostic and curative sciences. He has also prescribed and ethical charter for medical practitioners two centuries prior to the Hippocratic oath. Through his genius and intuition, Acharya Charak made landmark contributions to Ayurvedal. He forever remains etched in the annals of history as one of the greatest and noblest of rishi-scientists.

Homi J. Bhabha

Famous Indian nuclear physicist Homi Jehangir Bhabha was born on 30 October 1909 in Mumbai. Bhabha played a key role in the development of the Indian atomic energy program. Widely referred to as the father of India's nuclear weapons program, Bhabha had his education at the Elphinstone College and the Royal Institute of Science before obtaining his doctorate from the University of Cambridge in 1934. He was influenced greatly by the legendary Paul Dirac. Bhabha was a research scientist at the Cavendish Laboratories at Cambridge. When he was stranded in India as a result of the Second World War, he set up the Cosmic Ray Research Unit at the Indian Institute of Science, Bangalore under Nobel Laureate C. V. Raman in 1939.

Dr. Bhabha is credited with establishing the Tata Institute of Fundamental Research(TIFR) with the help of eminent industrialist J. R. D. Tata. After India won independence from the British, Bhabha established the Atomic Energy Commission of India in 1948. He represented India in various international forums including the United Nations and his tenure represented a high in terms of the progress of India's atomic energy programme. The climax of this programme came on May 18, 1974 when India exploded a nuclear device at Pokhran, Rajasthan joining a select club of nations.

This legendary scientist died in an air crash near Mont Blanc on Januuary 24, 1966. Many possible theories have been advanced for the aircrash, including a conspiracy theory. The atomic energy centre in Trombay was renamed as Bhabha Atomic Research Centre in his honour. In addition to being a famous scientist, Bhabha was also a painter and a classical music and opera enthusiast, besides being an amateur botanist.

Vikram Sarabhai

Considered as the Father of the Indian Space Program, Vikram Ambalal Sarabhai was born on 12th August 1919 to Ambalal Sarabhai and Sarala Sarabhai. After matriculating from the Gujarat College, he cleared the Intermediate Science Examination and moved to London. He joined St. John's College, University of Cambridge. Due to the problems of Second World War he returned to India and joined the Indian Institute of Science, Bangalore.

This innovator got married to the famous dancer of that time, Mrinalini Sarabhai in 1942. The whole family of Vikram Sarabhai was involved in freedom struggle and he himself was greatly influenced by Mahatma Gandhi. Vikram Sarabhai again went abroad and after getting doctorate's degree for his thesis 'Cosmic Ray Investigation in Tropical Latitudes', Sarabhai returned to India in 1947. After returning to an independent India he felt the need of science and technology for the development of the nation. He wholeheartedly plunged into developing the Space Programs of India. He was not an ordinary scientist interested in just development of rockets and space programs instead was the man who was inclined to use all the aspects of science and technology as 'levers of development'.

To help the cause of the developing India, Vikram Sarabhai founded the Physical Research Laboratory in Ahmedabad. He was not just a scientist, but a dreamer, an innovator who not only developed science and technology institutions but also laid the foundation of some of the developmental and management institutes. The Indian Institute of Management (IIM), Ahmedabad and the Nehru Foundation for Development are the two world- famous organizations established by this philanthropist. He also set up Ahmadabad Textiles Industrial Research Association(ATIRA),Centre for Environmental Planning and Technology (CEPT) and Blind Man Association(BMA). One of the greatest achievements of Vikram Sarabhai was the development of Indian Space Research Organization (ISRO). It was due to his efforts that this space organization came into being.

Vikram Sarabhai left for his heavenly abode on 31st December 1971 at Kovalam.

Aryabhatta

1.Aryabhatta:
Aryabhatta is a renowned mathematician and astronomer of ancient India. He was born in 476 AD in Kerala. He studied at the University of Nalanda. One of his major work was Aryabhatiya written in 499 AD. The book dealt with many topics like astronomy, spherical trigonometry, arithmetic, algebra and plane trigonometry. He jotted his inventions in mathematics and astronomy in verse form. The book was translated into Latin in the 13th century. Through the translated Latin version of the Aryabhattiya, the European mathematicians learned how to calculate the areas of triangles, volumes of spheres as well as how to find out the square and cube root.

In the field of astronomy, Aryabhatta was the pioneer to infer that the Earth is spherical and it rotates on its own axis which results in day and night. He even concluded that the moon is dark and shines because of the light of sun. He gave a logical explanation to the theory of solar and lunar eclipses. He declared that eclipses are caused due to the shadows casted by the Earth and the moon. Aryabhatta proposed the geocentric model of the solar system which states that the Earth is in the center of the universe and also laid the foundation for the concept of Gravitation. His propounded methods of astronomical calculations in his Aryabhatta-Siddhatha which was used to make the the Panchanga (Hindu calendar). What Copernicus and Galileo propounded was suggested by Aryabhatta nearly 1500 years ago.

Aryabhatta's contribution in mathematics is unparalleled. He suggested formula to calculate the areas of a triangle and a circle, which were correct. The Gupta ruler, Buddhagupta, appointed him the Head of the University for his exceptional work. Aryabhatta gave the irrational value of pi. He deduced ? = 62832/20000 = 3.1416 claiming, that it was an approximation. He was the first mathematician to give the 'table of the sines', which is in the form of a single rhyming stanza, where each syllable stands for increments at intervals of 225 minutes of arc or 3 degrees 45'. Alphabetic code has been used by him to define a set of increments. If we use Aryabhatta's table and calculate the value of sin(30) (corresponding to hasjha) which is 1719/3438 = 0.5; the value is correct. His alphabetic code is commonly known as the Aryabhata cipher.

Venkatraman Ramakrishnan and Thomas Steitz and Israeli Ada Yonath Scientists

Americans Venkatraman Ramakrishnan and Thomas Steitz and Israeli Ada Yonath won the 2009 Nobel Prize in chemistry on Wednesday for mapping ribosomes, the protein-producing factories within cells, at the atomic level.

India-born Venkatraman Ramakrishnan is a senior scientist at the MRC Laborartory of Molecular Biology at Cambridge.Born in 1952 in Chidambaram, Tamil Nadu, Ramakrishnan shares the Nobel prize with Thomas E Steitz (US) and Ada E Yonath (Israel) for their "studies of the structure and function of the ribosome".Ramakrishnan earned his B.Sc. in Physics (1971) from Baroda University and his Ph.D. in Physics (1976) from Ohio University.He moved into biology at the University of California, San Diego, where he took a year of classes, then conducted research with Dr Mauricio Montal, a membrane biochemist."This year's Nobel Prize in Chemistry awards Venkatraman Ramakrishnan, Thomas A Steitz and Ada E Yonath for having showed what the ribosome looks like and how it functions at the atomic level," the Nobel committee said in its citation. All three have used a method called X-ray crystallography to map the position for each and every one of the hundreds of thousands of atoms that make up the ribosome, it said.

"This year's three Laureates have all generated 3D models that show how different antibiotics bind to the ribosome. These models are now used by scientists in order to develop new antibiotics, directly assisting the saving of lives and decreasing humanity's suffering," the citation said.

Better known as Venky among friends, Ramakrishnan started out as a theoretical physicist. After graduate school, he designed his own 2-year transition from physics to biology.

As a postdoctoral fellow at Yale University, he worked on a neutron-scattering map of the small ribosomal subunit of E Coli. He has been studying ribosome structure ever since.

Ramakrishnan has authored several important papers in academic journals.

In the August 26, 2000 issue of Nature, Ramakrishnan and his coworkers published the structure of the small ribosomal subunit of Thermus thermophilus, a heat-stable bacterium related to one found in the Yellowstone hot springs.

With this 5.5 Angstrom-resolution structure, Ramakrishnan's group identified key portions of the RNA and, using previously determined structures, positioned seven of the subunit's proteins. In the September 21, 2000 issue of Nature, Ramakrishnan published two papers. In the first of these, he presents the 3 Angstrom structure of the 30S ribosomal subunit.

His second paper reveals the structures of the 30S subunit in complex with three antibiotics that target different regions of the subunit. In this paper, Ramakrishnan discusses the structural basis for the action of each of these drugs.

After his postdoctoral fellowship, Ramakrishnan joined the staff of Brookhaven National Laboratory in ther US. There, he began his collaboration with Stephen White to clone the genes for several ribosomal proteins and determine their three-dimensional structures.

He was also awarded a Guggenheim fellowship during his tenure there, and he used it to make the transition to X-ray crystallography.

Ramakrishnan moved to the University of Utah in 1995 to become a professor in the Department of Biochemistry. There, he initiated his studies on protein-RNA complexes and the entire 30S subunit.

He since moved to the MRC Laboratory of Molecular Biology in Cambridge, where he is a Senior Scientist and Group Leader in the Structural Studies Division. He joins the list of several Nobel laureates who worked at the laboratory.

The Royal Swedish Academy of Sciences said their work has been fundamental to the scientific understanding of life and has helped researchers develop antibiotic cures for various diseases.

Yonath is the fourth woman to win the Nobel chemistry prize and the first since 1964, when Dorothy Crowfoot Hodgkin of Britain received the prize.

This year's three laureates all generated three-dimensional models that show how different antibiotics bind to ribosomes.

``These models are now used by scientists in order to develop new antibiotics, directly assisting the saving of lives and decreasing humanity's suffering,'' the academy said in its announcement.

``All three have used a method called X-ray crystallography to map the position for each and every one of the hundreds of thousands of atoms that make up the ribosome,'' the academy said.

Alfred Nobel, a Swedish industrialist who invented dynamite, established the Nobel Prizes in his will in 1895. The first awards were handed out six years later.

Each prize comes with a 10 million kronor ($1.4 million) purse, a diploma, a gold medal and an invitation to the prize ceremony in Stockholm on Dec. 10. The Peace Prize is handed out in Oslo.

On Monday, three American scientists shared the Nobel Prize in medicine for discovering a key mechanism in the genetic operations of cells, an insight that has inspired new lines of research into cancer.

The physics prize on Tuesday was split between a Hong Kong-based scientist who helped develop fiber-optic cable and two Canadian and American researchers who invented the ``eye'' in digital cameras _ technology that has revolutionized communications and science.

The literature and peace prize winners will be announced later this week and the economics announcement is set for Monday.

Har Gobind Khorana

Har Gobind Khorana is an Indian-American molecular biologist. He was awarded the Nobel Prize in Physiology or Medicine in 1968. An intense worker of the interpretation of the genetic code and its functioning in protein synthesis, Har Gobind Khorana was also awarded the Louisa Gross Horwitz Prize from Columbia University in the same year. Har Gobind Khorana became a naturalised citizen of the United States in 1966, and eventually received the National Medal of Science.

Har Gobind Khorana was born in Raipur, Kabir Wala, in January 9, 1922. He spent his childhood in a poor village in British India. Har Gobind Khorana`s father was the village "patwari", or taxation official and his father home schooled him. Later he was admitted in the D.A.V. Multan High School and he finished his B.Sc. from Punjab University, Lahore in 1943 and M.Sc from Punjab University in 1945. Har Gobind Khorana began his studies at the University of Liverpool in 1945. After being awarded a PhD in 1948, he continued his postdoctoral studies in Zürich, until 1949.

Later, Har Gobind Khorana spent two years at Cambridge and his interests in proteins and nucleic acids started at that time. In 1952 he went to the University of British Columbia, Vancouver and in 1960, he moved to the University of Wisconsin-Madison. In 1970, Har Gobind Khorana became the prestigious Alfred Sloan Professor of Biology and Chemistry at the Massachusetts Institute of Technology where he worked until retiring in 2007. A member of the Board of Scientific Governors at The Scripps Research Institute, Har Gobind Khorana currently holds Professor Emeritus status at MIT.

Har Gobind Khorana was married to Esther Elizabeth Sibler, who is of Swiss origin, in 1952. They together have three children, Julia Elizabeth (born May 4th, 1953), Emily Anne (born October 18th, 1954), and Dave Roy (born July 26th, 1958). Har Gobind Khorana worked with Ribonucleic acid (RNA), with two repeating units (UCUCUCU ? UCU CUC UCU) and produced two alternating amino acids. This combined with the Nirenberg and Leder experiment and showed that UCU codes for Serine and CUC codes for Leucine.

Har Gobind Khorana also worked with the RNAs with three repeating units (UACUACUA ? UAC UAC UAC, or ACU ACU ACU, or CUA CUA CUA) and thus produced three different strings of amino acids. RNAs with four repeating units including UAG, UAA, or UGA, produced only dipeptides and tripeptides and deduced that UAG, UAA and UGA are stop codons. In this way, Har Gobind Khorana and his team had established that the mother of all codes, the biological language common to all living organisms, is spelled out in three-letter words that are each set of three nucleotides codes for a specific amino acid.

The Nobel lecture of Har Gobind Khorana was delivered on December 12, 1968. He was also the first to create oligonucleotides or the strings of nucleotides and also to isolate DNA ligase, an enzyme that links pieces of DNA together. These custom-designed pieces of simulated genes are extensively used in biology labs for sequencing, cloning and engineering new plants and animals. This invention of Har Gobind Khorana has become mechanical and commercialised so that anyone now can order an unreal gene from any of a number of companies and one merely needs to fax the genetic sequence to one of the companies and receive an oligonucliotide with the preferred sequence.

Har Gobind Khorana once again proved the capability of Indian scientists and their researches that were accredited internationally

Prasanta Chandra Mahalanobis an Indian Scientist

Prasanta Chandra Mahalanobis (June 29, 1893-June 28, 1972) was an Indian scientist and applied statistician. He is best known for the Mahalanobis distance, a statistical measure. He did pioneering work on anthropometric variation in India. He founded the Indian Statistical Institute, and contributed to large scale sample surveys. His father, Prabodh Chandra, was an active member of the Sadharan Brahmo Samaj. His mother, Nirodbasini, belonged to a family of considerable academic achievements. He graduated in Physics in 1912 from the Presidency College, Kolkata and completed Tripos at King's College, Cambridge. He then returned to Calcutta. Inspired by the Biometrika and mentored by Acharya Brajendranath Seal he started his statistical work. Initially he worked on analyzing university exam results, anthropometric measurements on Anglo-Indians of Calcutta and some metrological problems. He also worked as a meteorologist for some time. In 1924, when he was working on the probable error of results of agricultural experiments, he met Ronald Fisher, with whom he established a life-long friendship. He also worked on schemes to prevent floods. His most important contributions are related to large scale sample surveys. He introduced the concept of pilot surveys and advocated the usefulness of sampling methods. His name is also associated with the scale free multivariate distance measure, the Mahalanobis distance. He founded the Indian Statistical Institute on 17 December, 1931.
In later life, he contributed prominently to newly independent India's five-year plans starting from the second. His variant of Wassily Leontief's Input-output model was employed in the second and later plans to work towards rapid industrialisation of India and with his colleagues at his institute, he played a key role in developing the required statistical infrastructure. He also had an abiding interest in cultural pursuits and served as secretary to Rabindranath Tagore, particularly during the latter's foreign travels, and also his alma mater Visva Bharati University, for some time.He received one of the highest civilian awards Padma Vibhushan from the Government of India for his contribution to science and services to the country. He died on Jun 28, 1972, a day before his seventy-ninth birthday. Even at this age, he was still active doing research work and discharging his duties as the Secretary and Director of the Indian Statistical Institute and as the Honorary Statistical Advisor to the Cabinet of the Government of India. He had got Weldon Medal from Oxford University in 1944 and Padma Vibhushan in 1968. He was also elected a fellow of the Royal Society, London in 1945 and Honorary President of International Statistical Institute in 1957.

Birbal Sahni,a great Indian Scientist

A Great scientist who lived only for knowledge. He declined high posts. He was a genius who shone in several spheres. He was a great teacher and a great man.Birbal Sahni, FRS (1891-1949) was an Indian paleobotanist who studied the fossils of the Indian subcontinent. He founded what is today the Birbal Sahni Botanical Institute in Lucknow, India. Birbal Sahni was born on 14th November 1891 and got his early education in India at Lahore and graduated from Emmanuel College, Cambridge in 1914. He later studied under Professor A. C. Seward, and was awarded the D.Sc. degree of London University in 1919. He returned to India and served as Professor of Botany at Banaras Hindu University, Varanasi and Punjab University for about a year. In 1921, he was appointed as the first Professor and Head of the Botany Department of the Lucknow University. The University of Cambridge recognized his researches by the award of the degree of Sc. D. in 1929. During the following years he not only continued his investigations but collected around him a group of devoted students from all parts of the country and built up a reputation for the University which soon became the first Center for botanical and palaeobotanical investigations in India. He established the Institute of Palaeobotany under the aegis of The Palaeobotanical Society on 10th September, 1946 which initially functioned in the Botany Department of Lucknow University but later moved to its present premises at 53 University Road, Lucknow in 1949. On 3rd April, 1949 the Prime Minister of India Jawaharlal Nehru laid down the foundation stone of the new building of the Institute, however, a week later, on 10th April 1949, Professor Sahni succumbed to a heart attack. Professor Sahni was recognized by several academies and institutions in India and abroad for his research. He was elected a Fellow of the Royal Society of London (FRS) in 1936, the highest British scientific honor, awarded for the first time to an Indian botanist.
His greatest contribution was the discovery of a new group of fossil gymnosperms which he called the "Pentoxyleae".

Bharath Gyan

Bharath Gyan, a Chennai-based NGO engaged in research on India's traditions and culture, has produced a report which states that Lord Ram did indeed exist, and even put a date on his birth: January 10, 5114 BCE (Before the Christian Era).

The Colonial British historians who came to shape our thoughts about 200 years back called Ramayana and other texts of India as mythological.

How right were they in their branding Indian Itihaasa as mythological? In the last decade or so, the scientific advancements that have taken place, have helped scientific historians revisit the text for historical proofs.

Bharath Gyan has researched information on Rama from a rational, scientific and logical perspective to try and understand if Rama has in reality been a historical person.

Design Engineering

K Ramanathan, Head, United Nations ESCAP - APCTT, spoke in length about Design Engineering and its impact on improving competitiveness. He said that firms compete on the basis of customer value creation and the customer value is a function of quality, delivery, flexibility, convenience and cost. Ramanathan held that design engineering is an important element of technological capability portfolio of a firm and should include design engineering, design for manufacturability, design for maintenance, etc.

R&D in Agriculture,Health and Infrastructure.

Dr DV Singh of Roorkee University, while outlining the role of public-private partnership in Govt policy said that the issue never figured out in Govt's Science and Technology statement as late as 1981. It was only in the policy statement of 2003 that the govt stressed the need of R&D in Agriculture, Health and Infrastructure. He said that India has more than 300 R&D institutions where 1000 of compounds are synthesised annually. India has also become a vaccine hub for major pharmaceutical companies. "Given these facts, India should be recognised as a high-skilled-manpower country rather than backstage of R&D," he said.

Connecticut Retreat for the Insane,Hartford, Connecticut

The Fellows of the Connecticut State Medical Society voted to petition the state legislature for an act of incorporation and funding of a public institution for the care of people with mental illness. The legislature did so and, on January 27, 1823, the Society voted to locate the facility at Hartford, on land owned by Ira Todd. The Connecticut Retreat for the Insane, later named the Hartford Retreat, opened for the admission of patients in 1824.

The Connecticut Retreat's name and humane philosophy of treatment were patterned after those of the York Retreat, in England. The first superintendent of the Hartford Retreat was Eli Todd. The institution's name has changed several times but was called the Hartford Retreat for many years. It is now named the Institute of Living.

Walter Dill Scott was first applied psychologists

Walter Dill Scott(1869-1955) was born on a farm near the town of Normal, Illinois. Scott’s father was ill; therefore all the responsibility of running the farm was put on Walter’s shoulders. While plowing a field one afternoon, he had the idea about work efficiency. Scott realized that if he was going to accomplish anything, he would need to stop wasting time. Scott realized that he lost ten minutes out of his time; he could be doing something important, every time he gave the cows a ten minute rest. So he decided to carry a book around with him and spend every spare minute of his time reading and learning something new (Schultz & Schultz, 2004).

Scott wanted to go to college, but in order to do that he had to pick and can blackberries, salvaged scrap metal to sell and take on other odds jobs. At age nineteen, he enrolled at Illinois State Normal University. He wanted to become a missionary to China, but by the time he graduated from Chicago theological seminary there were no room for missionaries. Scott then started taking a liking to psychology when he enrolled in a psychology class and enjoyed it, and when he read a magazine article about Wundt’s Leipzig laboratory (Schultz & Schultz, 2004).

On July 21, 1898, Scott went to study with Wundt, and then two years later he obtained his Ph.D. Scott then became a psychology and pedagogy instructor at Northwestern University. A few years later his interest changed when an advertising executive asked him to think of a way to apply psychology to advertising to make it more successful (Schultz & Schultz, 2004).

In 1903, Scott wrote The Theory and Practice of Advertising, the first book on the topic of advertising. In 1905, he was promoted to professor and in 1909, he was appointed to professor of applied psychology and director of the bureau of salesmanship research at Pittsburgh Carnegie Technical University (Schultz & Schultz, 2004).

When the United States entered World War I, Scott offered to help the army select military personal. At first his ideas were not well liked; and not everyone was convinced about psychology’s practical values. An army general was not convinced on Scott’s selection techniques, but eventually Scott was able to persuade the general in using his selection techniques. Scotts was later rewarded with the army’s Distinguished Service Metal (Schultz & Schultz, 2004).

After World War I, Scott formed his own company called The Scott Company. His company provided consulting services to corporations wanting assistance with problems of personal selection and worker efficiency. While running his own company, he was also president of Northwestern University from 1920 to 1939 (Schultz & Schultz, 2004).

Scott argued that consumers do not act rational, and therefore they can be easily influenced. He said that emotion, sympathy, and sentimentality are all factors that increase consumer suggestibility. Applying his laws of suggestibility, he recommended that companies use direct commands to sell their products. He suggested that companies use return coupons because they required consumers to take direct action. His techniques were used by advertisers and by 1910 were used all over the country (Schultz & Schultz, 2004).

Scott came up with a rating scale and group test to measure characteristics of people who were already successful as sales people, business executives, and military personal. He also questioned army officers and business managers, asking them to rank the importance of appearance, demeanor, and character. Scott then ranked job applicants on the qualities found for effective job performance. Scott also developed psychological test to measure intelligence and other abilities, but instead of individual test he made test that could be given to groups of people. Scott was not only measuring general intelligence but he was also interested how a person applies their intelligence. He defined intelligence in practical terms such as judgment, quickness, and accuracy. He compared applicants’ test scores with scores of employees who were successful, and was not concerned about what those test scores would say about the personals mental problems (Schultz & Schultz, 2004).

Sanger, Dr Frederik: British scientist awarded Nobel Prize in Chemistry in 1958 for his work in determining the composition of the insulin molecule. By his discovery he has put science a step forward towards knowing how disease attacks the human body. In 1980, he became only the fourth person ever to be awarded a second Nobel Prize.

Sarabhai, Dr Vikram A.: former Chairman of India’s Atomic Energy Commission and the Indian Space Research Organization (ISRO) died on December 30, 1971. Dr Sarabhai was an eminent physicist mainly interested in the astrophysical implications of Cosmic Ray Time Variations.

Sen, P.K. (Dr): is the Indian surgeon who performed Asia’s first heart transplant operation in Mumbai.

Simpson, Sir James Young: (1811-70) British physicist who was largely instrumental in the introduction of chloroform as an anaesthetic in 1847.

Soddy, Frederick: (1877-1956) British physical chemist. He was a pioneer of research into atomic disintegration. He coined the term “isotopes”; did classic work on radioactivity.

Solvay, Earnest: (1838-1922) Belgian chemist known for devising a process known after his name for manufacture of sodium carbonate.

Susruta: was a fourth century Hindu surgeon and physician. He wrote an important book on medicine and also a thesis on the medical properties of garlic.

Sutherland, Dr Earl W.: was the recipient of the Nobel Prize for Medicine, 1971. He is credited with the discovery that the hormones in the human body produce another substance known as cyclic A.M.P., which activates them and controls the body’s cells. He has demonstrated that changes in the level of cyclic A.M.P. in the body can influence its disease-resisting capacity. This discovery opens up new vistas for the development of drugs that can treat diseases which have so far been regarded as incurable.

Teller, Edward (Dr): is a U.S. nuclear scientist who has played a major role in developing the hydrogen bomb. He is in fact known as the “father of the H-bomb”.

Thomson, Sir J.J.: (1856-1940) British physicist. He discovered the electron which inaugurated the electrical theory of the atom. He is regarded as the founder of modern physics.

Tsiolkovsky: was a Russian teacher who in 1903 published a treatise presenting remarkably accurate calculations on rocket dynamics and space-travel. He is looked upon as the earliest among the pioneers who laid the foundations of space exploration. The Russians call him the “Father of Rocketry”.

Varahmihira: (505-587) was a distinguished Indian astronomer, mathematician and philosopher. He was one of the nine gems of the court of king Vikramaditya.

Verne, Jules: (1828-1905) French science-fiction writer was author of “From the Earth to the Moon” published in 1865. The book carried a more or less accurate prediction of the launching and flight of Apollo-8.

Volta, A.: (1745-1827) Italian physicist and pioneer of electrical science; invented voltaic pile, the electrophorus and electroscope. The volt is named after him.

Voronoff, S.: Russian scientist best known for his method of preventing or delaying senility by grafting healthy animal glands, into the human body.
