This volume brings together a collection of essays on the history and philosophy of probability and statistics by one of the eminent scholars in these subjects. Written over the last fifteen years, they fall into three broad categories. The first deals with the use of symmetry arguments in inductive probability, in particular, their use in deriving rules of succession. The second group deals with three outstanding individuals who made lasting contributions to probability and statistics in very different ways: Frank Ramsey, R.A. Fisher, Alan Turing, and Abraham de Moivre. The last group of essays deals with the problem of "predicting the unpredictable."
Essays on Supersymmetry by C. Fronsdal,M. Flato,T. Hirai Pdf
to our own also needs to be understood. Such unification may also require that the supersymmetry group possess irreducible representations with infinite reductiori on the Poincare subgroup, to accommodate an infinite set of particles. Such possibilities were 5 envisaged long ago and have recently reappeared in Kaluza-Klein . 6 d' . th 7 S . l' th supergraVlty an m superstnng eory. upersymmetry Imp Ies at forces that are mediated by bose exchange must be complemented by forces that are due to the exchange of fermions. The masslessness of neutrinos is suggestive-we continue to favor the idea that neutrinos are fundamental to weak interactions, that they will finally play a more central role than the bit part assigned to them in Weinberg-Salam theory. There seems to be little room for doubting that supersymmetry is badly broken-so where should one be looking for the first tangible manifestations of it? It is remarkable that the successes that can be legitimately claimed for supersymmetry are all in the domain of massless particles and fields. Supergravity is not renormalizable, but it is an improvement (in this respect) over ordinary quantum gravity. Finite super Yang-Mills theories are not yet established, but there is now a strong concensus that they soon will be. In both cases massless fields are involved in an essential way.
Vol. 1 represents a new ed. of papers which were originally published in Essays on mirror manifolds (1992); supplemented by the additional volume: Mirror symmetry 2 which presents papers by both physicists and mathematicians. Mirror symmetry 1 (the 1st volume) constitutes the proceedings of the Mathematical Sciences Research Institute Workshop of 1991.

Selected Essays of Wilson Harris by A.J.M. Bundy Pdf
Wilson Harris is one of the outstanding literary innovators of the century. His novels date from The Palace of the Peacock to Jonestown . This long-awaited volume matches Harris's career with his critical writings, from 1961 to the present day. Selected Essays of Wilson Harris brings together twenty-one lectures, addresses and essays to make available Harris's full range of writings on subjects including: * the literate imagination * traditions of myth and fable in Central and South America * the North American literary imagination, from Edgar Allen Poe, Herman Melville and Ralph Ellison, to William Faulkner and Jean Rhys * inheritances and legacies of writers of the postcolonial diaspora This comprehensive collection also comes complete with: * an extensive editorial introduction, providing valuable historical and theoretical context for the essays * a map of Guyana * bibliographies of Harris's fiction and non-fiction * appendices on the legends of El Dorado and the Holy Grail.
Essays on Life Sciences, with Related Science Fiction Stories by Pier Luigi Luisi Pdf
This collection of essays highlights, in a new, critical fashion, some of the classic questions in life science. These include “what is life?”; “what is death?”; “what is consciousness?”; “why is life cellular?”; and “why are enzymes macromolecules?”. It also explores whether evolution is pre-determined, whether science and spirituality can harmonize with each other, whether artificial intelligence is at odds with the human spirit, and whether, and to what extent, we are genetically determined. In this text, some of the main conceptual tools used to tackle life’s many aspects are necessarily reviewed, such as the systems view of life, the notion of contingency, and the concept of autopoiesis. Each of the three chapters of the book contains a number of short science fiction stories which discuss aspects of the present-day development of artificial intelligence.
From Summetria to Symmetry: The Making of a Revolutionary Scientific Concept by Giora Hon,Bernard R. Goldstein Pdf
Many literary critics seem to think that an hypothesis about obscure and remote questions of history can be refuted by a simple demand for the production of more evidence than in fact exists. The demand is as easy to make as it is impossible to satisfy. But the true test of an hypothesis, if it cannot be shown to con?ict with known truths, is the number of facts that it correlates and explains. Francis M. Cornford [1914] 1934, 220. It was in the autumn of 1997 that the research project leading to this publication began. One of us [GH], while a visiting fellow at the Center for Philosophy of Science (University of Pittsburgh), gave a talk entitled, “Proportions and Identity: The Aesthetic Aspect of Symmetry”. The presentation focused on a confusion s- rounding the concept of symmetry: it exhibits unity, yet it is often claimed to reveal a form of beauty, namely, harmony, which requires a variety of elements. In the audience was the co-author of this book [BRG] who responded with enthusiasm, seeking to extend the discussion of this issue to historical sources in earlier periods. A preliminary search of the literature persuaded us that the history of symmetry was rich in possibilities for new insights into the making of concepts. John Roche’s brief essay (1987), in which he sketched the broad outlines of the history of this concept, was particularly helpful, and led us to conclude that the subject was worthy of monographic treatment.
Symmetry and Economic Invariance by Ryuzo Sato,Rama V. Ramachandran Pdf
Symmetry and Economic Invariance (second enhanced edition) explores how the symmetry and invariance of economic models can provide insights into their properties. Although the professional economist of today is adept at many of the mathematical techniques used in static and dynamic optimization models, group theory is still not among his or her repertoire of tools. The authors aim to show that group theoretic methods form a natural extension of the techniques commonly used in economics and that they can be easily mastered. Part I provides an introduction that minimizes prerequisites including prior knowledge of group theory. Part II discusses recent developments in the field.
