Perfect Rigour

In 2006, an eccentric Russian mathematician named Grigori Perelman solved one of the world's greatest intellectual puzzles. The Poincare conjecture is an extremely complex topological problem that had eluded the best minds for over a century. In 2000, the Clay Institute in Boston named it one of seven great unsolved mathematical problems, and promised a million dollars to anyone who could find a solution. Perelman was awarded the prize this year - and declined the money. Journalist Masha Gessen was determined to find out why. Drawing on interviews with Perelman's teachers, classmates, coaches, teammates, and colleagues in Russia and the US - and informed by her own background as a math whiz raised in Russia - she set out to uncover the nature of Perelman's astonishing abilities. In telling his story, Masha Gessen has constructed a gripping and tragic tale that sheds rare light on the unique burden of genius.

A gripping and tragic tale that sheds rare light on the unique burden of genius In 2006, an eccentric Russian mathematician named Grigori Perelman solved the Poincare Conjecture, an extremely complex topological problem that had eluded the best minds for over a century. A prize of one million dollars was offered to anyone who could unravel it, but Perelman declined the winnings, and in doing so inspired journalist Masha Gessen to tell his story. Drawing on interviews with Perelman’s teachers, classmates, coaches, teammates, and colleagues in Russia and the United States—and informed by her own background as a math whiz raised in Russia—Gessen uncovered a mind of unrivaled computational power, one that enabled Perelman to pursue mathematical concepts to their logical (sometimes distant) end. But she also discovered that this very strength turned out to be Perelman's undoing and the reason for his withdrawal, first from the world of mathematics and then, increasingly, from the world in general.

More than any other major twentieth-century writer, Pierre Duhem has been the victim of ill-informed guesswork. For instance, many references to Duhem stress the importance of his Catholic faith, but nearly all of them draw the obvious-and entirely erroneous-conclusions about the role of Catholicism in Duhem's thinking. This book pays particular attention to the political and intellectual context of French Catholicism, wracked as it was by the tensions of Dreyfus affair and the so-called modernist crisis. Duhem took his inspiration, not from the papally-sponsored revival of the thought of St. Thomas Aquinas, but from Pascal, a fact that aroused suspicions of skepticism in the minds of conservative Catholics. The tensions between Duhem's work and authoritarian Catholic positions became more explicit as his historical work unfolded. Most famous for his denial of the possibility of a crucial experiment which could unambiguously decide between contending scientific theories, Duhem has often been interpreted as a mere instrumentalist or conventionalist, denying the meaningfulness of a reality behind the theory. Dr. Martin shows that Duhem was a Pascalian who argued for both logic and intuition as indispensable in approaching the truth. Duhem argues that physics could not legitimately be used to attack Christianity, but he held that physics was equally useless for the defense of Christianity, a position which made him unpopular with many Catholics.

This volume presents different conceptions of logic and mathematics and discuss their philosophical foundations and consequences. This concerns first of all topics of Wittgenstein's ideas on logic and mathematics; questions about the structural complexity of propositions; the more recent debate about Neo-Logicism and Neo-Fregeanism; the comparison and translatability of different logics; the foundations of mathematics: intuitionism, mathematical realism, and formalism.

Reviewing research evidence for nursing practice: systematic reviews highlights the key issues involved in conducting different types of systematic reviews - encompassing qualitative studies, quantitative studies and combining quantitative and qualitative studies. It enables nurses and researchers to understand the key principles involved in preparing systematic reviews and to critically appraise the reviews they read and evaluate their usefulness in developing their own practice. Each section starts with an overview of the methodology, followed by a selection of systematic reviews carried out in specialist areas of nursing practice. Part 1 explores systematic reviews and meta-analysis of quantitative research, part 2 explores meta-synthesis and meta-study of qualitative research and part 3 addresses integrative reviews that combine both qualitative and quantitative evidence. The final part explores the use of systematic reviews in service and practice development.

Graciela De Pierris presents a novel interpretation of the relationship between skepticism and naturalism in Hume's epistemology, and a new appraisal of Hume's place within early modern thought. Whereas a dominant trend in recent Hume scholarship maintains that there are no skeptical arguments concerning causation and induction in Book I, Part III of the Treatise, Graciela De Pierris presents a detailed reading of the skeptical argument she finds there and how this argument initiates a train of skeptical reasoning that begins in Part III and culminates in Part IV. This reasoning is framed by Hume's version of the modern theory of ideas developed by Descartes and Locke. The skeptical implications of this theory, however, do not arise, as in traditional interpretations of Hume's skepticism, from the 'veil of perception.' They arise from Hume's elaboration of a presentational-phenomenological model of ultimate evidence, according to which there is always a justificatory gap between what is or has been immediately presented to the mind and any ideas that go beyond it. This happens, paradigmatically, in the causal-inductive inference, and, as De Pierris argues, in demonstrative inference as well. Yet, in spite of his firm commitment to radical skepticism, Hume also accepts the naturalistic standpoint of science and common life, and he does so, on the novel interpretation presented here, because of an equally firm commitment to Newtonian science in general and the Newtonian inductive method in particular. Hume defends the Newtonian method (against the mechanical philosophy) while simultaneously rejecting all attempts (including those of the Newtonians) to find a place for the supernatural within our understanding of nature.

Designed for novice as well as more experienced researchers, Reason & Rigor by Sharon M. Ravitch and Matthew Riggan presents conceptual frameworks as a mechanism for aligning literature review, research design, and methodology. The book explores the conceptual framework—defined as both a process and a product—that helps to direct and ground researchers as they work through common research challenges. Focusing on published studies on a range of topics and employing both quantitative and qualitative methods, the updated Second Edition features two new chapters and clearly communicates the processes of developing and defining conceptual frameworks.

Originally published in 1919, this work on the philosophy of mathematics is both expensive and hard to find in its first edition. It contains Bertrand Russell's ideas on number definition, cardinal numbers, propositional functions and much more. This is a fascinating work and thoroughly recommended for anyone interested in the philosophy of mathematics. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
