PM's speech at the 125th Birth Anniversary Celebrations of Ramanujan at Chennai

“We have gathered here today to celebrate the life and work of a great son of India and of Tamil Nadu, and one of the greatest mathematicians the world has seen. It is a pleasure to participate in this function in the memory of Srinivas Ramanujan, whose extraordinary genius so very brightly lit up the world of mathematics in the second decade of the last century. Men and women of such dazzling brilliance and deep intellect are born but rarely. Indeed, Srinivas Ramanujan's genius was ranked by the English mathematician G. H. Hardy in the same class as giants like Euler, Gauss, Archimedes and Isaac Newton. While we rightly claim Ramanujan as one of our own, he equally belonged to all humanity like the other great men and women in any sphere of human thought.

Before I proceed further, let me compliment the Ministry of Human Resource Development, and my colleague Kapil Sibal, for planning year long celebrations to mark the 125th birth anniversary of Ramanujan. As a tribute to the great mathematician, our government has decided to declare his birthday, that is December 22, as the National Mathematics Day and the year 2012 as a whole as the National Mathematical Year. India has a long and glorious tradition of mathematics that we need to encourage and nurture. I hope these steps will help in providing the additional impetus to the study of mathematics in our country, apart from making our people more aware of the work of Ramanujan.

Mathematics seems to have acquired an independent identity as an intellectual discipline early on in human history. This identity became more sharply defined in the second half of the millennium before Christ, thanks to major developments in Greece. In this period, India too made great strides in mathematics, though in ways very different from the Greeks. In the early centuries of the Common Era, India was in fact in the lead in mathematical developments. Aryabhata in the fifth century, followed by Brahmagupta in the next are reckoned to be among the all-time great mathematicians. And we taught the world to think of zero as a number and the modern way of representing all numbers with 10 symbols. This arguably is the single most important mathematical development in all human history.

Indian mathematics remained in the forefront for almost a thousand years following Aryabhata. The last name in the great mathematicians we produced in this period is that of Madhava of Kerala. I understand Madhava had discovered the essentials of Calculus some two centuries before Newton and Leibnitz. His work however was not known beyond the school he had created in Kerala. That school unfortunately did not last beyond the middle of the 16th century.

Intellectual activity receded into the background in the country for the next few centuries to revive only in the nineteenth century. In the early part of the nineteenth century, most of our intellectual energies were given to humanities and it is towards the end of the century that India began taking an interest in the sciences. In the second decade of the 20th century, the country could once again stake a claim to producing world class mathematics, and that was because of the work of Srinivasa Ramanujan. Ramanujan came from an economically disadvantaged background and had but a minimal training in mathematics and yet his genius overcame formidable difficulties to reach the pinnacle of greatness. The whole of India is proud of Ramanujam and many an Indian has been inspired by his shining example. Tamil Nadu of course has a special claim on him for he was a Tamilian. Along with Sir C. V. Raman and Subramanyam Chandrashekhar, he is among the three great men of science and mathematics that Tamil Nadu and India have given to the world in modern times.

The story of Ramanujan cannot be told without a mention of the Cambridge mathematician G. H. Hardy, who was responsible for Ramanujan getting the recognition that was his legitimate due. The parts that Hardy and Cambridge, which became Ramanujan's alma-mater, played in the great mathematician’s development represent the very best of the academic traditions of the West. The stories of the special relationship between G.H. Hardy and Ramanujan are a part of the folklore of mathematics.

The fascinating and inspiring story of Ramanujan needs to be told to the world. I am, therefore, very happy that the organizers have chosen this occasion to honour Professor Robert Kanigel who has written an excellent biography of Ramanujan and I am very happy that he is present here among us today. I greet you sir, and I understand that yours is a book that has made Ramanujan well known to the public at large all over the world, capturing vividly the atmosphere of the early nineteenth century academic world in that part of the world as well as in Britain. I am also happy that on this occasion, a new edition of the Notebooks of Ramanujan is also being released. These are photographic reproductions of unpublished mathematical work of Ramanujan, written out in his own hand in a series of notebooks during the days he spent in the city of Chennai. The originals, I am told are in the University of Madras and I congratulate the University authority for preserving them in its archives.

The Government of India sets great store by science and has pursued a policy of encouraging scientific activities of diverse kinds. Given our traditions, we naturally attach special importance to mathematics. Since Ramanujan, a number of mathematicians from the country have distinguished themselves by performing at very high levels. However, it is a matter of concern that for a country of our size the number of competent mathematicians that we have is badly inadequate. Over more than the last three decades many of our young men and women with a natural ability in mathematics have not pursued the discipline at advanced levels. This has also resulted in a decline in the quality of our mathematics teachers both at the school and college levels. There is a general perception in our society that the pursuit of mathematics does not lead to attractive career opportunities. This perception must change. This perception may have been valid some years ago but today there are many new career opportunities available to mathematicians, and the teaching profession itself has become much more attractive in recent years.

The mathematical community has a duty to find out ways and means to address the shortage of top quality mathematicians in our country. It must reach out to the public particularly in the modern context where mathematics has tremendous influence on every kind of human behaviour. In many ways, mathematics can be regarded as the mother science. The Natural Sciences have had a long symbiotic relationship with mathematics. Life Sciences did not seem to have much use for mathematics till about a hundred years ago, but lately mathematical interventions have had a tremendous impact on Biology. Mathematics has also influenced the study of Social Sciences in a big way. The work of many of the Nobel Laureates in Economics is highly mathematical. Students, parents and people at large need to be more aware of these facts so that the study of mathematics as an academic discipline gains popularity in our country. I am happy that the activities planned in the National Mathematical Year would focus on promotion of mathematics at all levels- from schools to cutting edge research.

The Ramanujan story illustrates the inadequacy of the university evaluation system in the early decades of the last century while at the same time it shows that the system displayed enough flexibility to take care of mavericks like Ramanujan. There have been many reforms since those days but there would still be talent which would elude proper evaluation. Our institutions of higher learning, therefore, must be sensitive to this problem. A genius like Ramanujan would shine bright even in the most adverse of circumstances, but we should be geared to encourage and nurture good talent which may not be of the same caliber as that of Ramanujan.

Let me end by wishing the National Mathematical Year all success. I expect the activities initiated during this year would be continued in the coming years as well, so as to help our country make it to the forefront of education and research in mathematics. That is my ardent prayer and with these words I thank you for listening to me patiently.”

SUBMERGE the polemics, legal tangles and conflicting technical claims, and the participants in the inter-State dispute over the Mullaperiyar dam – one of the oldest and highest ‘solid masonry gravity dams' in the world – will no longer be able to ignore the anxiety and panic that the 116-year-old structure has created among the people in Idukki, especially, and four other districts in Kerala.

The spontaneous initial outpouring of the people was followed by unusual protests demanding the decommissioning of the dam in the wake of intense rain and repeated low-intensity tremors in Idukki district, at locations over 30 kilometres away from Mullaperiyar, on November 18 and 26.

Following seasonal rains in the catchment areas of the dam, the reservoir was fast filling up when the first of the quakes occurred, and the spillway level of 136 feet (41.45 metres) was crossed within a few days.

The dam filled to capacity and the series of “minor” earthquakes activated an unprecedented unity of purpose in Kerala. Ever since the detection of fresh leaks on the dam's surface in 1979, people have demanded that the water level in the reservoir be lowered and a new dam be built.

The protests have taken the form of silent marches, hunger strikes, hartals and ‘human walls' in the five districts through which the Periyar flows, and other State-wide campaigns, some involving violence. The State government, on its part, demanded immediate mediatory and legal remedies from the Centre and the Supreme Court.

Mullaperiyar is the first in a series of hydroelectric and irrigation projects across Kerala's longest river, the Periyar, which originates in the Western Ghats and drains into the Arabian Sea and the backwaters near Kochi. Tamil Nadu, across the Western Ghats, is the sole beneficiary of the British-built dam and it is against any further reduction in the water level in the reservoir. Instead, it wants the level to be raised to 142.40 ft (43.4 m), as an interim measure, and further to 152 ft (46.32 m), as per the recommendations of a committee of the Central Water Commission (CWC) that examined the dam nearly two decades ago and suggested several measures to strengthen it.

By constructing the dam in the deep jungles of the Western Ghats, about 2,800 ft (853 m) above sea level, the British rulers of the then Madras Presidency had, from 1895, diverted the West-flowing Periyar river across the Ghats to the east, through a 5,704-feet (1,738.5 m) tunnel that opened into a tributary of the Vaigai river in the then Madurai district. This remarkable engineering feat achieved with the hard labour of mostly Indian workers today sustains irrigation and drinking water supply in five districts of southern Tamil Nadu. (The Periyar is also known as the Mullaperiyar, after a tributary, the Mullayar, joins it about 50 km from its origin in the Sivagiri Hill, east of Peerumedu.)

Though the dam is located in Kerala, it is controlled, managed and operated by Tamil Nadu, under a lease agreement of 1886 between the British and the erstwhile Travancore State, and validated subsequently by Kerala and Tamil Nadu in 1970.

The original agreement gave the British the right over “all the waters” of the Mullaperiyar and its catchment for diversion to the British territory (now Tamil Nadu) for 999 years. The waters of a river with about 5,284 square kilometres (out of a total of 5,398 sq km) of its catchment area in Kerala, stored in a reservoir within Kerala territory, thus came to be used exclusively by the people of southern Tamil Nadu from 1895 onwards, when the diversion project was inaugurated. According to one estimate, over 70 lakh people in Tamil Nadu's Theni, Dindigul, Madurai, Sivaganga and Ramanathapuram districts today depend on the waters of the Mullaperiyar reservoir (the scenic Thekkady lake) for the irrigation of about 2.5 lakh acres (1 acre = 0.4 hectare) and for drinking water needs. The (upper) Periyar has thus transformed a once-drought-prone region in the southern part of Tamil Nadu into breathtaking green valleys, vineyards and rich fields growing paddy, banana, coconut and a variety of vegetables and fruit. Since 1970, Tamil Nadu has been using the water to generate 140 megawatt (MW) of electricity as well.

In 1979, Tamil Nadu was forced to reduce the water level in the reservoir after detection of leaks in the dam. However, its requirement of the Periyar waters for irrigation had only been increasing year after year. The total irrigated area in the Periyar-Vaigai basin has expanded substantially, leading to a quantum jump in the water required from the reservoir. Farmers' groups in Tamil Nadu area have demanded that the Mullaperiyar water level be raised and “new channels” be opened from the Periyar system for irrigating new areas.

During most of the Periyar project's early history, the section of Kerala falling on the downstream areas of the reservoir seemed to have remained generally a water-surplus region, with plenty of rain (and meagre population in the Ghat areas). But from the late 1970s, soon after Kerala constructed the Idukki hydroelectric project 50 km downstream of the Mullaperiyar dam and denudation and encroachment of the surrounding areas increased, the State too began to feel the pinch. But it could not use (particularly during summer) even a wee drop from the huge source of water within its own territory.

For most part of the year, no water flowed from the Mullaperiyar reservoir to Kerala even as the population in the valleys between the Idukki and Mullaperiyar dams too began to increase. Almost all the water that reached the Idukki reservoir for most part of the year was only from the catchment areas downstream and from the Periyar's tributaries.

Safety concerns

The detection of leaks in the Mullaperiyar dam in 1979 had led to concerns about the dam's safety even though the reservoir level was brought down to 136 ft. Minor earthquakes were regularly reported in the region, and by the 1990s, Kerala government representatives, in private conversations, began expressing bitterness at the insensitivity of Tamil Nadu to the security concerns in Kerala. “Whether any State can rely permanently on the resources of another State” was a question that began to be raised, but at no time was there a demand that the Periyar waters be denied to Tamil Nadu.

A senior adviser to the State government on Inter-State River Water Disputes put it succinctly to Frontline in October 1998, when the dispute had reached a new low: “The case of the Mullaperiyar dam is peculiar in that the beneficiary is comfortably situated elsewhere and the donor stands to face the peril if something happens. Some experts have said the dam is safe. But can any government afford to throw caution to the winds?”

WE CELEBRATED OUR MOTHER'S 70 TH BIRTHDAY AT OOTTY


It was a good experience that we have gone to ootty to celebrate our mother's birth day at OOTTY.

To feel the touch of nature, Ooty is a right spot for the lover of nature. It is located at a distance of 105 km away from Coimbatore. It sparkles with fresh vegetation and sceneries. It is “queen of all hill station”. The height of the hills in the Nilgiri range varies between 2280 and 2290 meters. It attracts the tourist by its charming flowers. Lofty mountains, dense forest, acres and acres of tea estates are green feast for the eyes of the tourist.

The fast food world man runs his life in this world of tension; and living in the sweltering heat; to while away his short leisure hour he can spend that with nature (ooty).The weather of valley is salubrious. Ooty is a best place to know the culture and tradition of India and tribal people.

Botanical gardens, lamb’s rock and Dobabetta peak, kalhatty fallskandal, cross shrine, mini garden and rose garden; Mudumalai Wildlife Sanctuary and National Park are till more amusing places in Ooty and its surroundings. Ooty lake boating is a remarkable spot which highly entertains the tourist. Udagamandalam otherwise called as Ooty. Its mountain train journey on a ratchet and restrain track which commences from kallar will give a new adventures effect. Finally Nature never betrays the tourist.

MAGIC OF SSLC

The newly introduced grading system has helped children and their parents overcome fear. The coverage given by the media to rank holders has had a negative impact on other students. This is one reason why suicide rates among students in this age group increased. The government should take steps to reduce the number of dropouts before the next academic year begins. One must not forget that the SSLC examination is not the end of the road called education, but a gateway for further learning.There is no doubt that the SSLC examination results this year were fantastic. But the common man is not foolish to believe that it happened just because the system of evaluation changed. The inflated success in the examination has only devalued the average standard of education.

There was a time when people used to respect the quality of education in south India and Kerala, in particular. But now the authorities have managed to change the impression. The standards of education cannot be raised in one stroke.

It is dangerous to deliver a message that one can get through the examination without putting in much effort. To raise the scale of success, ‘moderation’ was used generously. Even though this has helped in reducing anxiety among students, the seats for higher studies are limited to those who scored well.

In this new system, hardly anyone fails.

We can streamline the process by introducing an entrance examination for admission to Plus Two.
