This article explores the place of computation in the history of quantum theory by examining the development of several approximation methods to solve the Schröödinger equation without using empirical information, as these were worked out in the years from 1927 to 1933. These ab initio methods, as they became known, produced the results that helped validate the use of quantum mechanics in many-body atomic and molecular systems, but carrying out the computations became increasingly laborious and difficult as better agreement between theory and experiment was pursued and more complex systems were tackled. I argue that computational work in the early years of quantum chemistry shows an emerging practice of theory that required human labor, technological improvement (computers), and mathematical ingenuity.

The chapter is a prologue to the main narrative of the book. It offers an evaluation of Macaulay’s minute which paved the way for introduction of modern education in India, the idea of National System Of Education which dominated Indian thinking on education for over sixty years from the Partition of Bengal (1905) to the Kothari Commission (1964), and the division of responsibility between the Central and Provincial Governments for educational development during British Raj. It offers a succinct account of the key recommendations of the landmark Sarjent Committee on Post-War Educational Development, the Radhakrishnan Commission on University Development, and the Mudaliar Commission on Secondary Education, of the drafting history of the provisions relating to education in the Constitution, the spectacular expansion of access after Independence, the evolution of regulatory policies and institutions like the University Grants Commission (UGC), and of the delicate compromise over language policy.

Abstract This biographical essay is designed to give a survey of Constantin Brunnerʼs early years, from his childhood and youth until the end of his student days, based on the available letters, manuscripts and published writings. A major focus is on Brunnerʼs intellectual development from protected child, spiritually shaped by Jewish orthodoxy, to aspiring religious scholar and finally to the secular philosopher known today. The article is therefore a contribution to a range of research topics: to the field of German-Jewish biography during the period of the German Empire; but also to the history of ideas, particularly in relation to the secularization of religious minorities. It also touches upon developments inside the Jewish community: the way different intellectual and religious currents are related to each other, the informal networks between Jewish intellectuals and how national (German or Jewish) identity is related to the Jewish self-image.

This article contributes to the debate about the history of the political economy of the European Economic Community (EEC). It retraces the efforts during the early years of the EEC to implement a form of ‘European economic programming’, that is, a more ‘dirigiste’ type of economic governance than is usually associated with European integration. Based on a variety of archives, it offers a new account of the making and failure of this project. It argues that, at the time, the idea of economic programming found many supporters, but its implementation largely failed for political as well as practical reasons. In so doing, it also brings to light the role of economists during the early years of European integration.


Richard Nichols, The Diaries of Robert Hooke, The Leonardo of London, 1635-1703 . Lewes, Sussex: The Book Guild, 1994, Pp. 185, £15.00. ISBN 0- 86332-930-6. Richard Nichols is a science master turned historian of science who celebrates in this book Robert Hooke’s contributions to the arts and sciences. The appreciation brings together comments from Hooke’s Diaries , and other works, on each of his main enterprises, and on his personal interaction with each of his principal friends and foes. Further references to Hooke and his activities are drawn from Birch’s History of the Royal Society, Aubrey’s Brief Lives , and the Diaries of Evelyn and of Pepys. The first section of the book, ‘Hooke the Man’, covers his early years of education at home in Freshwater, at Westminster school and at Christ Church, Oxford, where he soon joined the group of experimental philosophers who set him up as Curator of the Royal Society and Professor of Geometry at Gresham College, Bishopsgate. Hooke’s domestic life at Gresham College is described - his intimate relationships with a series of housekeepers, including his niece, Grace Hooke, and his social life at the College and in the London coffee houses.

This article provides a succinct but comprehensive review of the history of the American Academy of Podiatric Sports Medicine. Three time periods are described: the pre-academy era, the early years of podiatric sports medicine leading up to the academy’s founding, and the academy’s founding and the 1970s. An appreciation of the academy’s past facilitates understanding of its present state and future direction. (J Am Podiatr Med Assoc 93(4): 315-320, 2003)

The article is devoted to the early years of formation of Kharkiv scenography school and to the creative and pedagogical activities of Olexander Khvostenko-Khvostov (1895–1967). It was reported that the bold experiments of this artist, in the field of theatrical design of 1918–1922, made him one of the central figures of Kharkiv avant-garde scene (“Mystery Buff”; “The Army in the City”; “Lilyuli”, etc), strengthening the reputation of an innovator and causing the beginning of pedagogical activity at the Kharkiv Art College in 1921. The theatrical and decorative workshop was opened at the faculty of painting at the Kharkiv Art College in 1922, it was headed by A. Khvostenko-Khvostov. Among the first graduates were such bright alumni as A. Volnenko, P. Suponin, V. Ryftin, A. Bosulaev, B. Chernyshov, and others. Fundamental provisions of the educational program, which A. Khvostenko borrowed from the teaching practice of A. Exter (Kyiv Studio, 1918–1920), reflected the formation idea of future theater artist’s synthetic thinking. It is known that the education program of the Theater and Scenery Workshop of KAC, equally with the Studio of A. Exter, in addition to the subjects common to all students of painting and drawing faculty as special subjects (theatrical scenery, technique and technology of the stage, etc.) included also the history of theater (I. Turkeltaub), material culture, costume, music and literature (A. Beletsky). O. Khvostenko paid special attention to theoretical and practical issues of composition. He introduced the course of fundamentals of directing (V. Vasilko) as a compulsory subject. Much of what the students mastered at the Workshop was tested on the professional stages of Kharkiv theaters. Associated with the Kharkiv Art School for a quarter of a century (1921–1946), O. Khvostenko-Khvostov has not still been included in the pantheon of its outstanding teachers.

Automatic speech processing (ASP) is understood as covering word recognition, the processing of higher linguistic components (syntax, semantics, and pragmatics), and the processing of computational paralinguistics (CP), which deals with speaker states and traits. This chapter attempts to track the role of prosody in ASP from the word level up to CP. A short history of the field from 1980 to 2020 distinguishes the early years (until 2000)—when the prosodic contribution to the modelling of linguistic phenomena, such as accents, boundaries, syntax, semantics, and dialogue acts, was the focus—from the later years, when the focus shifted to paralinguistics; prosody ceased to be visible. Different types of predictor variables are addressed, among them high-performance power features as well as leverage features, which can also be employed in teaching and therapy.

It may be of interest to the Society if I submit to its notice some observations made last year, which render it necessary to re-write the history of one of the best known monuments of Rome.The monument, which for fifty-six years has been called the Column of Phocas, was formerly, when nothing but the pillar itself was seen above ground, the subject of much curiosity and speculation among the visitors of the Forum. The “nameless column with the buried base” was thought by some to be the sole relic of a great temple or other public building. By others it had been conjectured to be part of the famous bridge by which Caligula united his palace on the Palatine with the temple of Capitoline Jupiter. In the early years of the century, among other works of the same kind, it was resolved to clear away the soil and débris from the substructure of this column; and on the 13th of March, 1813, the inscription of its pedestal, which had remained for centuries a few feet below the level of the ground, was uncovered, and revealed the fact that it had supported a statue dedicated by the exarch Smaragdus to the honour of a Caesar, whose name had been erased, but who, by other indications, could be no other than Phocas, an emperor of evil reputation, but to whom Rome and the world owe some gratitude for having been instrumental in dedicating the Pantheon to Christian worship, and so preserving from ruin one of the noblest and most original architectural works of antiquity.
