Modelling of post-rain attenuation of microwaves at 22·235 GHz in relation to vertical transport of water vapour

Abstract Attenuation of microwaves (up to 30 GHz) around the water vapour absorption line on 22·235 GHz tends to persist even after the stoppage of rain during the monsoon season. A theoretical model has been developed for the post-rain residual absorption of radio waves at 22·235 GHz (λ = 1·349 cm) by considering the vertical transport of water vapour in the region of the rain event. The theoretical estimate agrees fairly well with that obtained experimentally during different post-rain events, recorded by a radiometer, operating at the Institute of Radio Physics and Electronics, Calcutta University on a round-the-clock basis.

Economics at Columbia: Recollections of the Early 1930S

Two articles, one by W. Allen Wallis on the Mathematical Statistics Group at Columbia University during World War II,1 and the other by Edward Shils on his graduate student days at the University of Chicago in the 1930s,2 have encouraged me to set down my recollections of the Economics Department at Columbia Univer sity during the early 1930s when Wesley Clair Mitchell and John Maurice Clark gave it luster, if not leadership. Their peers in the economics profession at large had selected Mitchell and Clark as the first and second recipients respec tively of the John Bates Clark medal awarded by the American Economic Association to those who had made the greatest contributions to the advance of the discipline. Within three short years at the end of the 1920s the center of gravity of the Economics Department at Columbia shifted radically. In 1928 Henry Moore, an early contributor to mathematical-statistical studies of economics, retired and disappeared from the academic scene where he had never played a prominent role. In 1930 Edwin R. A. Seligman, the long-term chairman of the department suffered a mild heart attack; he retired to be succeeded by Henry Seager, a specialist in labor, who died that same summer while on a visit to Eastern Europe. Seligman was a man of parts. Three decades earlier he had written a little book, The Economic Interpretation of History which pro vided academic respectability to American scholars who sought to deal seriously with Karl Marx.3 He had a long list of contributions to public finance and had played an important role in getting the federal income tax law onto the books. A man of independent means, he supported many students, especially foreign students who ran out of funds. Just prior to his retirement he had completed a major inquiry into consumer credit, a project financed by General Motors, for which it was reported he had received a fee of $250,000 ($2 million in 1989 dollars!) Seligman concluded that there was nothing wrong from the viewpoint of economics or ethics in consumers buying on credit. A Jew by birth, and a leading member of the Ethical Culture Society, Seligman was much conflicted about his Jewishness, especially when confronting those of Zionist persuasion. He once told me that he had contributed to the University of Calcutta but, as a matter of principle, refused to make a donation to the Hebrew University in Jerusalem. Aware of the anti-Semitism in elite U.S. universities, he was concerned about the prospects of young Jewish academicians. One amusing episode: After his retirement, he continued to come to the campus and sought to stay abreast of what was happening. I told him in one of our frequent meetings of a talented new student, Moses Abramovitz. He asked how he spelled his name. When I indicated it was with a v rather than a w, Seligman indicated great relief. The hard core of the old department in addition to Seligman, Seager and Moore in cluded Vladimir G. Simkhovitch who offered courses on socialism and economic history. Russian by birth and German by education, Simkhovitch, even with the perspective of time is not easy to characterize and even harder to evaluate. A collector of Chinese art and a grower of delphiniums in Perry, Maine, he was recognized as an expert in both fields. Most students, the bright as well as the dull, considered his lectures somewhat tedious dis traction from serious work on contemporary economics; they had little interest in his exhaustion of the soil explanation for the decline of Rome4 or his Edward Bernstein-modified critique of Karl Marx.5 But a few of us recognized V. G.'s insightfulness and over looked his failings, defects which included a proneness for character defamation and vindic tiveness as well as immature behavior toward female students.

The National Atlas of India

The Atlas of is not only a significant contribution to understanding the geography of India but also one of the best national atlases in the world.1 Published in English, the atlas contains eight volumes. As a product of the postcolonial era that is geared to economic development, particularly agriculture, this atlas unfolds divergent regional characteristics in the context of a nationwide perspective. The atlas is an excellent display of Indian capabilities: planned and prepared with extreme precision by Indian geographers, the set was printed in color by the Survey of India. The same organization published a preliminary edition of the Atlas, but the 1982 atlas is far more elaborate and detailed than its predecessor.2 The 1957 edition was nonetheless a good beginning, but the new set is the most comprehensive, extensive, and accurate of all atlases published on India and South Asia. No other atlas provides a macro and meso regional treatment of India based on in-depth, data-oriented research and field investigation as does the Atlas. It is even asserted in the preface that the set is the world's largest national atlas. The originator and the guiding force of the atlas was S. P. Chatterjee, who until 1968 had been head of the geography department at the University of Calcutta. He founded and was named director of the National Atlas Organization in 1956. He held the position until his retirement in 1968. Prime Minister Nehru took special interest in establishing this organization as a part of the apparatus of the central government. In the summer of 1955 Chatterjee showed his pilot maps to Nehru and was much encouraged. Chatterjee pointed out that only a handful of countries had published national atlases, and that the U.S.S.R. was the only large country to have one. The publication of a national atlas was then a challenging project not only because India was a large, recently independent country with limited resources but also because it was a democracy. Chatterjee had previous experience preparing and publishing a sizable atlas, Bengal in Maps.3 He undertook the challenge of a national atlas and succeeded. He was supported by a large group of geographers who were primarily trained in the British system of traditional geography that prevailed in Indian universities after the British gave up political control of the country. The National Atlas Organization with a centralized office in Calcutta has a hierarchy of officers and technical and nontechnical personnel. S. P. Dasgupta followed Chatterjee as director in the late 1960s. B. K. Dutt replaced

Mechanism of Shoulder Movements and a Plea for the Recognition of ???Zero Position??? of Glenohumeral Joint

Towards a metaphysic of self

The four sections below are concerned with an article of Professor Krish nachandra Bhattacharyya (1875—1949) on 'Mind and Matter'. The text of the article appears in the second section. The article is published here for the first time. It has been found in the unpublished manuscripts of Professor Bhattacharyya. For kind permission to print this article of his father's, I am indebted to my teacher Professor Kalidas Bhattacharyya. Professor Krishnachandra Bhattacharyya was King George V Professor of Philosophy in the University of Calcutta in the mid-thirties. By common consent, he is the most original and creative among the academic philosophers of India, situating Indian thought in the perspective of the world-philosophy of his time and, what is most important in a philosophic context, creatively reacting to Western thought and thus making additions to the corpus of philosophy. Professor Bhattacharyya's task was thus vastly different from, and more complex than, the task of those who, at the turn of the century of British rule in India, contented themselves with just comparing and contrasting Indian and Western philosophical concepts: important as such work undoubt edly was, all that it amounted to was writing history of philosophy. The much-needed creative reaction to Western thought was possible on the part of Professor Bhattacharyya because, while he did react with a traditional mind (if we may say so), he did not continue traditionalism. As a true philosopher who does not ignore his historical milieu but on the contrary makes history contemporary, Professor Bhattacharya exploited the big jolt that Indian mind received through the West by trying to formulate, initially in Western terms, the logic of the notions or concepts of Indian thought and then bring out the differentia of that logic. Only thus is one's mentality restored to oneself, only thus is any originality in thought possible. The article which is being printed is not dated by Professor Bhattacharyya. However, in his notebook from which the article is extracted, there is a 'list of the work' which Professor Bhattacharyya contemplated completing

Bibhutibhusan datta (1888–1958), historian of Indian mathematics

Born to a poor Bengali family, Bibhutibhusan Datta (1888–1958) was indifferent to wordly pleasures and gains. He never married. His doctoral thesis was on hydrodynamics, but he is best known for his work on the history of mathematics. He retired voluntarily from the University of Calcutta at the age of 45 and in 1938 took sany a sa (literally, renunciation) to become known as Swami Vidyaranya. He also wrote on Indian religion and philosophy.

Bose Institute of Physical Sciences, University of Calcutta in July 1978.

The universities and the government in Sri Lanka

AT the end of the nineteenth century the British colony of Ceylon, now Sri Lanka, had a well-developed system of primary and secondary schools but no university. In the early decades of that century the island's most esteemed secondary school, the Colombo Academy supported ,and directed by the state, was the main if not sole centre for such courses of higher education as existed. Later known as Queen's College it became affiliated to Calcutta University in 1859. Renamed Royal College, it became the first "col lege" 1 to provide some form of post-matriculate education since it prepared students for the external examinations conducted by the University of London. Few students, ho~,ever, proceeded beyond the intermediate examination. The children of the wealthier ctasses were sent to British universities for their educabion, and the less affluent went to universities in India. Medical education was better provided through the Ceylon Medical College which was established .in 1870. In general, ho,wever, the island continued to depend on institutions overseas to meet its need for the education of medical personnel as well in the other professions. By the last quarter of the nineteenth century .there was increasing demand by the island's educated classes for the establishment of a university in Ceylon. By the first decade of the twentieth century, this agitation had developed into what came to be known as " t h e university movement". The early natio.nalists regarded a university as essential to "national existence" and vital for .the purpose of arresting " the process of den, atio.nalisation ". The two outstanding figures in " the university movement" were the great orientalist, Ananda Coomaraswamy, and Sir Ponnambalam Arunachalam, who was the foremost Ceylonese civil servar~t of his day and who was soon to emerge as one of the outstanding Ceylonese political figures of the first quarter of the present century. The major premise of the arguments of the leading members of .the university movement was .that external examinations conducted by British universities were a poor substitute for a real university education in an indigenous university. In the Ceylon National Review, the journal of the Ceylon Social Reform League founded in 1905, Coomaraswamy sketched his ideal of a "Sri Dantean University ": an institution which would .impart an education and not merely " estimate ;the amountof knowledge possessed by
