Optic flow provides all the information necessary to guide a walking human or a mobile robot to its target. Over the past 50 years, a body of research on optic flow spanning the disciplines of neurophysiology, psychophysics, experimental psychology, brain imaging and computational modelling has accumulated. Today, when we survey the field, we find independent lines of research have now converged and many arguments have been resolved; simultaneously the underpinning assumptions of flow theory are being questioned and alternative accounts of the visual guidance of locomotion proposed. At this critical juncture, this volume offers a timely review of what has been learnt and pointers to where the field is going.

Philosophical Lectures on Probability contains the transcription of a series of lectures held by Bruno de Finetti (one of the fathers of subjective Bayesianism) and collected by the editor Alberto Mura at the Institute for Advanced Mathematics in Rome in 1979. The book offers a live in-context outlook on de Finetti’s later philosophy of probability. On several points de Finetti’s remarks revise widespread interpretations of his thought and reveal to be topical in the light of recent developments.

Abductive Reasoning: Logical Investigations into Discovery and Explanation is a much awaited original contribution to the study of abductive reasoning, providing logical foundations and a rich sample of pertinent applications. Divided into three parts on the conceptual framework, the logical foundations, and the applications, this monograph takes the reader for a comprehensive and erudite tour through the taxonomy of abductive reasoning, via the logical workings of abductive inference ending with applications pertinent to scientific explanation, empirical progress, pragmatism and belief revision.

Are Western epistemology, metaphysics, methodology and the philosophy of science grounded only in men's distinctive understandings of themselves, others, and nature? Does this less than human understanding distort our models of reason and of scientific inquiry? In different ways, the papers in this collection explore the evidence for these increasingly reasonable and intriguing questions. They identify how it is distinctively masculine perspectives on masculine experience which have shaped the most fundamental and formal aspects of systematic thought in philosophy and the natural and social sciences - precisely the aspects of thought believed most gender-neutral. They show how these understandings ground Aristotle's biology and metaphysics; the very definition of the problems of philosophy in Plato, Descartes, Hobbes and Rousseau; the `adversary method' which is the paradigm of philosophic and scientific reasoning; principles of individuation in philosophical ontology and the philosophy of language; individualistic assumptions in psychology; functionalism in sociological and biological theory; evolutionary theory; the methodology of political science; Marxist political economy; and conceptions of `objective inquiry' in the social and natural sciences. These essays also begin to identify for us the distictive aspects of women's experience which can provide the resources needed for the creation of a truly human understanding.

Mechanics is the science of motion of the bodies of the material universe. For centuries, this frame of our experience has been conceived in various manners.

Nature always tends to minimize its effort in achieving its goal. Whether it is the maxi- mum area of Queen Dido of Carthage, the minimum resistance of Newton or the shortest time of Bernouilli, most physical problems fall, theoretically at least, within the jurisdiction of variational calculus.

The German edition of this book appeared in 1932 under the title "Die gruppentheoretische Methode in der Quantenmechanik". Its aim was, to explain the fundamental notions of the Theory of Groups and their Representations, and the application of this theory to the Quantum Mechanics of Atoms and Molecules. The book was mainly written for the benefit of physicists who were supposed to be familiar with Quantum Mechanics. However, it turned out that it was also used by. mathematicians who wanted to learn Quantum Mechanics from it. Naturally, the physical parts were too difficult for mathematicians, whereas the mathematical parts were sometimes too difficult for physicists. The German language created an additional difficulty for many readers. In order to make the book more readable for physicists and mathe­ maticians alike, I have rewritten the whole volume. The changes are most notable in Chapters 1 and 6. In Chapter t, I have tried to give a mathematically rigorous exposition of the principles of Quantum Mechanics. This was possible because recent investigations in the theory of self-adjoint linear operators have made the mathematical foundation of Quantum Mechanics much clearer than it was in t 932. Chapter 6, on Molecule Spectra, was too much condensed in the German edition. I hope it is now easier to understand. In Chapter 2-5 too, numerous changes were made in order to make the book more readable and more useful.
