Savez-vous découvrir des sources souterraines ? faire bouger des portes en gonflant et dégonflant votre poitrine ? Prendre des charbons ardents entre vos mains ? Conduire la tête encagoulée ? Donner de violents coups de bâton sans faire mal à votre partenaire ? Êtes-vous doués de « pouvoirs » ? Ce livre vous montre comment y parvenir. Ce qui revient à déjouer les charlatans et marchands d’illusion qui cherchent à vous berner pour abuser de votre crédulité. Ainsi fait-on grand bruit autour du saint suaire de Turin ou du sang miraculeux de saint Janvier. Ce livre vous donne une recette, parmi d’autres, pour accomplir vous aussi ces miracles. Soyez miraculeux ! Contre l’autorité sectaire des gourous, il défend la pensée scientifique en vous amusant. Henri Broch est professeur de physique et directeur du laboratoire de zététique à l’université de Nice-Sophia-Antipolis. Il a publié, avec Georges Charpak, Devenez sorciers, devenez savants, qui a été un immense succès.
Written by one of the top experts in the fields of combinatorics and representation theory, this book distinguishes itself from the existing literature by its applications-oriented point of view. The second edition is extended, placing more emphasis on applications to the constructive theory of finite structures. Recent progress in this field, in particular in design and coding theory, is described.
This volume contains a collection of studies describing and analyzing stereotypes of women in the religions of Ancient Israel and Mesopotamia, and in Zoroastrianism, Judaism, Medieval Christianity, Islam, Indian Sufism, Hinduism, Buddhism, Tibetan religions, and modern Neopaganism. In all these traditions the stereotypes are based on generalizations, which are socially, culturally or religiously legitimized, and which seem to have a lasting influence on society's conceptions of women. They represent oversimplified opinions, which are, however, regularly challenged by the women who are affected by them. In all traditions the stereotypes are ambiguous, either because women have challenged their validity, or because historical developments in society have reshaped them. They influence public opinion by emphasizing dominant views, as a strategy to restrain women and to keep them controlled by the rules and morals of a male-dominated society.
Zeta and q-Zeta Functions and Associated Series and Integrals is a thoroughly revised, enlarged and updated version of Series Associated with the Zeta and Related Functions. Many of the chapters and sections of the book have been significantly modified or rewritten, and a new chapter on the theory and applications of the basic (or q-) extensions of various special functions is included. This book will be invaluable because it covers not only detailed and systematic presentations of the theory and applications of the various methods and techniques used in dealing with many different classes of series and integrals associated with the Zeta and related functions, but stimulating historical accounts of a large number of problems and well-classified tables of series and integrals. Detailed and systematic presentations of the theory and applications of the various methods and techniques used in dealing with many different classes of series and integrals associated with the Zeta and related functions
This book is an introduction to one of the important as pects of Numerical Analysis, namely the approximate solution of functional equations. We intend to show, by a few brief examples, the different theoretical and practical problems related to the numerical approximation of boundary value problems. We have chosen for this the approximate solution of certain linear elliptic partial differential equations (the first two parts of the book) and the approximate solution of a nonlinear elliptic differential equation. This book is not a systematic study of the subject, but the methods developed here can be applied to large classes of linear and nonlinear elliptic problems. The book assumes that the reader's knowledge of Anal ysis is comparable to what is taught in the first years of graduate studies. This means a good knowledge of Hilbert spaces, elements of measure theory and theory of distributions. The subject matter of the book covers the usual content of a first course on Numerical Analysis of partial differential equations.
Recent years have seen a spectacular rise of the New Age movement and an ever-increasing interest in its beliefs and manifestations. This fascinating work presents the first-ever comprehensive analysis of New Age Religion and its historical backgrounds, thus providing the reader with a means of orientation in the bewildering variety of the movement. Making extensive use of primary sources, the author thematically analyses New Age beliefs from the perspective of the study of religions. While looking at the historical backgrounds of the movement, he convincingly argues that its foundations were laid by so-called western esoteric traditions during the Renaissance. Hanegraaff finally shows how the modern New Age movement emerged from the increasing secularization of those esoteric traditions during the 19th century. This ground-breaking publication is compulsive reading for all those involved or interested in the New Age movement.
Astronomy is by nature an interdisciplinary activity: it involves mathematics, physics, chemistry and biology. Astronomers use (and often develop) the latest technology, the fastest computers and the most refined software. In this book twenty-two leading scientists from nine countries talk about how astronomy interacts with these other sciences. They describe modern instruments used in astronomy and the relations between astronomy and technology, industry, politics and philosophy. They also discuss what it means to be an astronomer, the history of astronomy, and the place of astronomy in society today.
Notwithstanding its title, the reader will not find in this book a systematic account of this huge subject. Certain classical aspects have been passed by, and the true title ought to be "Various questions of elementary combina torial analysis". For instance, we only touch upon the subject of graphs and configurations, but there exists a very extensive and good literature on this subject. For this we refer the reader to the bibliography at the end of the volume. The true beginnings of combinatorial analysis (also called combina tory analysis) coincide with the beginnings of probability theory in the 17th century. For about two centuries it vanished as an autonomous sub ject. But the advance o...
L.E.J. Brouwer (1881-1966) is best known for his revolutionary ideas on topology and foundations of mathematics (intuitionism). The present collection contains a mixture of letters; university and faculty correspondence has been included, some of which shed light on the student years, and in particular on the exchange of letters with his PhD adviser, Korteweg. Acting as the natural sequel to the publication of Brouwer’s biography, this book provides instrumental reading for those wishing to gain a deeper understanding of Brouwer and his role in the twentieth century. Striking a good balance of biographical and scientific information, the latter deals with innovations in topology (Cantor-Sc...
