Prasanta Chandra Mahalanobis

He sometimes spoke of "zero" as the symbol of the absolute (Nirguna Brahman) of the extreme monistic school of Hindu philosophy, that is, the reality to which no qualities can be attributed, which cannot be defined or described by words and which is completely beyond the reach of the human mind. According to Ramanujan the appropriate symbol was the number "zero" which is the absolute negation of all attributes.

Seng in "Professor P.C. Mahalanobis and the Development of Population Statistics in India"

The 'Mahalanobis Era' in statistics which started in the early twenties has ended. Indeed it will be remembered for all time to come as the golden period of statistics in India, marked by intensive development of a new technology and its applications for the welfare of mankind.

We believe that the idea underlying this integral concept of statistics finds adequate expression in the ancient Indian work Sankhya in |Sanskrit the usual meaning is ‘number‘, but the original root meaning was ‘determinate knowledge’ in the Atharva Veda a derivative from Sankhyata occurs both in the sense of ‘well-known‘ as well as ‘numbered’. The lexicons give both meanings. Amarakosa gives Sankhya – vicarana (deliberation, analysis) as well as ‘number’; also Sankhyavan – panditah (wise, learned).

What at first strongly attracted my admiration was that the Professor‘s work was not imitative….The experience of India will serve as a guidance and as an example worthy of imitating.

some evidence is available to indicate that, in India, an increase in the income of the poorer people leads to an increase in the size of the family; and also that this tapers off after a certain critical level of income is attained, and is followed by a reduction in the size of the family at higher levels of living When a sufficient number of people reach the critical income, there would be a gradual decrease in the average birth rate with further increase in income.

l have liked your article very much. The way you have narrated the history of my humanism in an evolutionary perspective has made this aspect of mine clearer even to me.

[He} was one of Tagore's rare friends who did not place him simply on a high pedestal full of only aura and fame, but treated him as a lively intellectual and affectionate companion.

Without the progress of equality and improvement in the level of living at least beyond the poverty line, for one quarter of the population of the world who live in South Asia, there would be grave repercussions on the rest of the world. The problem of the underdeveloped country is, in one sense, of greater concern to the advanced countries because international rivalries and tensions arise from the desire to establish spheres of influence over underdeveloped areas. The very existence of underdeveloped regions would he therefore a continuing threat to world security, and world peace. A quick transformation of the underdeveloped countries into industrialized economies would reduce the sphere of conflicting interests; and hence decrease the tension between East and West.

...l have been deeply struck by his broad and comprehensive approach to National Development and his astonishing energy. He is full of ideas and it is always a pleasure to discuss any subject with him.

No technique of random sample has, so far as I can find, been developed in the United States or elsewhere, which can compare in accuracy or in economy with that described by Professor Mahalanobis.

Just as Tagore sought to bring humanity closer through Visva-Bharati or his one-nest-world university at Santiniketan, Prasanta Chandra strove to use the ideal of humanism through statistics.

l have always noticed how you are always capable to maintain objectivity in your judgement about people and l have always recognised that to be a great quality in you.

It would be, however, a fatal mistake to establish an expensive system of education on the model of the advanced countries which would have little relevance to local needs and would be beyond the means of the national economy. It is necessary to evolve a system, through experimentation and trial and success, which would be within the means of the national economy.

Population in India is widely differentiated in ethnic composition, geographical and climatic conditions, social and cultural stratification, as well as by differences in economic status. Differential fertility therefore assumes a far more complex picture in India than anywhere in the world. Ethnic. geographical. socio-cultural and economic dilferences give a four-fold patterning with many complicated interactions. It is essential therefore to study different population groups separately.
