    Arnold. The theorem states that for general algebraical equations of a degree higher than 4, there are no formulas representing roots of these equations in terms of coefficients with only arithmetic operations and radicals.A secondary, and more important aim of this book, is to acquaint the reader with two very important branches of modern mathematics: group theory and theory of functions of a complex variable.This book also has the added bonus of an extensive appendix devoted to the differential Galois theory, written by Professor A.G. Khovanskii.As this text has been written assuming no specialist prior knowledge and is composed of definitions, examples, problems and solutions, it is suitable for self-study or teaching students of mathematics, from high school to graduate.

    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 distinctive aspects of women's experience which can provide the resources needed for the creation of a truly human understanding.
