Cellular Automata an Complexity | Stephen Wolfram usato Scienze Matematica e Ingegneria

Cellular Automata an Complexity | Stephen Wolfram usato Scienze Matematica e Ingegneria

Are mathematical equations the best way to model nature? For many years it had been assumed that they were. But in the early 1980s, Stephen Wolfram made the radical proposal that one should instead build models that are based directly on simple computer programs. Wolfram made a detailed study of a class of such models known as cellular automata, and discovered a remarkable fact: that even when the underlying rules are very simple, the behavior they produce can be highly complex, and can mimic many features of what we see in nature. And based on this result, Wolfram began a program of research to develop what he called “A Science of Complexity.”The results of Wolfram's work found many applications, from the so-called Wolfram Classification central to fields such as artificial life, to new ideas about cryptography and fluid dynamics. This book is a collection of Wolfram's original papers on cellular automata and complexity. Some of these papers are widely known in the scientific community; others have never been published before. Together, the papers provide a highly readable account of what has become a major new field of science, with important implications for physics, biology, economics, computer science and many other areas.

Knots and Surfaces | N. D. Gilbert, T. Porter usato Scienze Matematica e Ingegneria

This highly readable text details the interaction between the mathematical theory of knots and the theories of surfaces and group presentations. It expertly introduces several topics critical to the development of pure mathematics while providing an account of math "in action" in an unusual context. Beginning with a simple diagrammatic approach to the study of knots that reflects the artistic and geometric appeal of interlaced forms, Knots and Surfaces takes the reader through recent research advances. Topics include topological spaces, surfaces, the fundamental group, graphs, free groups, and group presentations. The authors skillfully combine these topics to form a coherent and highly developed theory to explore and explain the accessible and intuitive problems of knots and surfaces to students and researchers in mathematics.

Mapplethorpe. The complete flowers | Robert Mapplethorpe, Herbert Muschamp usato Fotografici Fotografia

Mapplethorpe. The complete flowers | Robert Mapplethorpe, Herbert Muschamp usato Fotografici Fotografia

Flower are one of the most common subjects for artwork, yet Mapplethorpe excels at bringing something radically new to his flower photographs. Setting them in a universe apart, their poses are classical, reduced to a series of essential forms. Their compositions are profoundly simple but mask a complex dynamic. Each one is evocative, and almost always sexually charged. When photographed by Mapplethorpe, these delicate organisms become almost muscular in their raw power. AUTHOR: Robert Mapplethorpe was born in 1946 and was raised in Long Island, New York. He received a B.F.A. from Pratt Institute in Brooklyn. By the early 1980s, he challenged the definition of photography with new techniques and formats. Mapplethorpe continued to create powerful images until his death from AIDS in 1989. 53 colour & 227 duotone photos

Argovian Sun | Andreas Dobler usato Arte Contemporanea

Argovian Sun | Andreas Dobler usato Arte Contemporanea

During the course of his anything but linear career, characterized by recurring excursions into other cultural areas including music, film and theater, painting has remained the most constant element in Andreas Doblers activities. In his youth, he was strongly influenced by pop music, psychedelic culture and its ties to the neo-surrealism of the 60s and 70s, as well as science fiction and comic aesthetics. He continues today to mine both media-oriented and popular culture, his taste for fantasy art and culture, ordinary subjects, the phenomena of pop culture and the aesthetic fringes of art having proven an abundant source for his figurative painting. In the 80s Doblers pictures often depicted objects taken from daily life (chest expanders, ski poles, cotton swabs, chocolate, etc.) combined in strange ways and lent a monumental aspect. Later, in the 90s, he used travel brochures to produce paintings and drawings of exotic hotel complexes with their palm trees, swimming pools and fantastically designed apartment buildings--spaces in which various desires are projected, allowing one to escape the day-to-day world. More than sarcastic commentary or simple pop icons, Doblers works translate his penchant for narrative and his interest in music and mise en scene, which he uses moreover as tools in his pictorial work.

Grammar and Meaning. A Semantic Approach to English Grammar | Howard Jackson usato Saggi di letteratura Linguistica

Grammar and Meaning. A Semantic Approach to English Grammar | Howard Jackson usato Saggi di letteratura Linguistica

Grammar and Meaning is an introduction to the study of grammar of contemporary English. It provides an impressive survey of all the main areas of English grammar, from words through to sentences and texts. It introduces and explains the linguistic terms needed to talk about the ways in which language works, from simple terms like adjective to more complex terms like non-finite clause. To meet the needs of both students and scholars, Howard Jackson has produced an innovative approach to the study of English grammar. Instead of concentrating on the formal and theoretical discussion of grammar, as many introductions do, this original analysis examines the 'meanings' we want to express when we use language. Beginning with the question, "What do we talk about?", it goes on to investigate how these meanings are structured in the grammar of English. These notions are closer to our ordinary understanding of what language is doing, and therefore the forms and structures of grammar are more easily grasped. The book is extensively illustrated with examples from real English. With analytical exercises in each chapter and a comprehensive glossary of terms, the book will prove and invaluable aid to students of English language, linguistics and English as a Foreign Language, whilst also being accessible to anyone who studies English grammar as part of their course.

Principles of Lasers | Orazio Svelto usato Scienze Fisica

Principles of Lasers | Orazio Svelto usato Scienze Fisica

R. G. Cooks This introduction has three purposes: (a) to summarize some of the chief features of energy spectrometry of ions and to sketch in a little of the background to this subject, (b) to present some simple facts about collision processes which one skilled in, say, mass spectrometry but innocent of any knowledge of bimolecular collisions might find of value, and (c) to indicate the scope and content of the volume. 1. The Subject This book takes as its subject, ion-molecule and ion-atom reactions occurring at high energies. It emphasizes the study of inelastic reactions at high energy through measurements of translational energy. The investiga tion of these reactions using other procedures has been important in the cases of the simpler systems. In particular, the emitted radiation has been investigated and this subject is therefore discussed where appropriate. For more complex species, however, there is little information available other than from energy spectra. The defining characteristic of the energy range of interest is that momentum transfer to the neutral target is negligible for small scattering angles. The result of this apparently bland condition is a welcome simplicity in the interpretation of the results of what appears to be developing into a R. G. Cooks • Department of Chemistry, Purdue University, West Lafayette, Indiana 47907. 2 Introduction unique form of spectroscopy. The names ion kinetic-energy spectrometry, translational energy spectrometry, collision spectroscopy, and energy-loss spectrometry have all been used to describe this subject (d. Section 5).

Four Colors Suffice - How the Map Problem Was Solved | Robin Wilson usato Scienze Matematica e Ingegneria

Four Colors Suffice - How the Map Problem Was Solved | Robin Wilson usato Scienze Matematica e Ingegneria

On October 23, 1852, Professor Augustus De Morgan wrote a letter to a colleague, unaware that he was launching one of the most famous mathematical conundrums in history--one that would confound thousands of puzzlers for more than a century. This is the amazing story of how the "map problem" was solved. The problem posed in the letter came from a former student: What is the least possible number of colors needed to fill in any map (real or invented) so that neighboring counties are always colored differently? This deceptively simple question was of minimal interest to cartographers, who saw little need to limit how many colors they used. But the problem set off a frenzy among professional mathematicians and amateur problem solvers, among them Lewis Carroll, an astronomer, a botanist, an obsessive golfer, the Bishop of London, a man who set his watch only once a year, a California traffic cop, and a bridegroom who spent his honeymoon coloring maps. In their pursuit of the solution, mathematicians painted maps on doughnuts and horseshoes and played with patterned soccer balls and the great rhombicuboctahedron. It would be more than one hundred years (and countless colored maps) later before the result was finally established. Even then, difficult questions remained, and the intricate solution--which involved no fewer than 1,200 hours of computer time--was greeted with as much dismay as enthusiasm. Providing a clear and elegant explanation of the problem and the proof, Robin Wilson tells how a seemingly innocuous question baffled great minds and stimulated exciting mathematics with far-flung applications. This is the entertaining story of those who failed to prove, and those who ultimately did prove, that four colors do indeed suffice to color any map. This new edition features many color illustrations. It also includes a new foreword by Ian Stewart on the importance of the map problem and how it was solved.

L'ethnométhodologie - Une sociologie radicale | Michel de Fornel, Albert Ogien, Louis Quéré usato Scienze umane Sociologia

L'ethnométhodologie - Une sociologie radicale | Michel de Fornel, Albert Ogien, Louis Quéré usato Scienze umane Sociologia

L'ethnométhodologie est un programme de recherche qui se propose d'aborder les phénomènes sociaux différemment des approches dominantes en sciences sociales. Il s'agit pour l'essentiel de revenir au concret, d'arriver, comme le disait Marcel Mauss, " à voir les choses sociales elles-mêmes comme elles sont ", c'est-à-dire telles qu'elles émergent et s'organisent dans l'expérience des agents sociaux, sans préjuger de leur définition. Ce parti pris s'accompagne d'une réorientation de l'analyse : l'explication théorique cède la place à la simple description. Un tel programme, qui implique de rompre tant avec l'intellectualisme qu'avec l'empirisme, a été à l'origine d'approches novatrices dans plusieurs domaines de recherche : l'étude des organisations, l'analyse du travail et de la coopération dans le travail, la sociologie des sciences et des techniques, l'étude de la communication sociale, l'analyse du discours, etc. Cet ouvrage collectif s'efforce de présenter l'état actuel de la recherche en ethnométhodologie, et tente d'évaluer, de façon raisonnée, l'importance de sa contribution aux sciences sociales, trente années après la parution de son ouvrage fondateur, Studies in Ethnomethodology, de Harold Garfinkel. Il poursuit ainsi une double ambition : approfondir la réflexion sur les difficultés - théoriques, conceptuelles, méthodologiques - rencontrées par ceux qui ont inscrit leurs recherches dans la perspective tracée par Garfinkel et ses collègues ; confronter les acquis des travaux en ethnométhodologie aux réactions qu'ils ont suscitées dans la sociologie française.

Ontogeny and phylogeny | Stephen Jay Gould usato Scienze Biologia

Ontogeny and phylogeny | Stephen Jay Gould usato Scienze Biologia

“Ontogeny recapitulates phylogeny” was Haeckel's answer—the wrong one—to the most vexing question of nineteenth-century biology: what is the relationship between individual development (ontogeny) and the evolution of species and lineages (phylogeny)? In this, the first major book on the subject in fifty years, Stephen Jay Gould documents the history of the idea of recapitulation from its first appearance among the pre-Socratics to its fall in the early twentieth century. Mr. Gould explores recapitulation as an idea that intrigued politicians and theologians as well as scientists. He shows that Haeckel's hypothesis—that human fetuses with gill slits are, literally, tiny fish, exact replicas of their water-breathing ancestors—had an influence that extended beyond biology into education, criminology, psychoanalysis (Freud and Jung were devout recapitulationists), and racism. The theory of recapitulation, Gould argues, finally collapsed not from the weight of contrary data, but because the rise of Mendelian genetics rendered it untenable. Turning to modern concepts, Gould demonstrates that, even though the whole subject of parallels between ontogeny and phylogeny fell into disrepute, it is still one of the great themes of evolutionary biology. Heterochrony—changes in developmental timing, producing parallels between ontogeny and phylogeny—is shown to be crucial to an understanding of gene regulation, the key to any rapprochement between molecular and evolutionary biology. Gould argues that the primary evolutionary value of heterochrony may lie in immediate ecological advantages for slow or rapid maturation, rather than in long-term changes of form, as all previous theories proclaimed. Neoteny—the opposite of recapitulation—is shown to be the most important determinant of human evolution. We have evolved by retaining the juvenile characters of our ancestors and have achieved both behavioral flexibility and our characteristic morphology thereby (large brains by prolonged retention of rapid fetal growth rates, for example). Gould concludes that “there may be nothing new under the sun, but permutation of the old within complex systems can do wonders. As biologists, we deal directly with the kind of material complexity that confers an unbounded potential upon simple, continuous changes in underlying processes. This is the chief joy of our science.”
