Download or read book Eccentric Symmetries written by Nancy Springer and published by Untreed Reads. This book was released on 2016-12-21 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eccentric Symmetries, 20 fantasy short stories spanning the forty-year career of author Nancy Springer, showcases tales ranging from the quirky to the transcendent. Including mythic tales of long ago and far away such as award-winner “The Boy Who Plaited Manes,” this collection also contains wry, sometimes humorous contemporary fantasy stories such as "Rumple What?" and "Snow Spawn," plus mystic magical realism in which cabbage roses grow down from the ceiling (“Mariposa”) and hard-edged future fantasy stories such as “We Don’t Know Why,” a tale of failing “angels.” Like our lives, the stories in Eccentric Symmetries are mostly off-kilter, even laughable, but sometimes achieve a luminous moment of perfect balance, an epiphany. In this carefully selected collection, every fantasy reader should find something to love.
Download or read book Symmetries and Dynamics of Star Clusters written by Jaroslav Haas and published by Springer Science & Business Media. This book was released on 2014-01-18 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this PhD thesis, which was nominated for publication in this series by the Astronomical Institute at Charles University, Prague, the author investigates the orbital evolution of an initially thin stellar disc around a supermassive black hole, considering various perturbative sources of gravity. His findings, obtained by both direct numerical N-body modelling and using standard perturbation methods, offer a viable theoretical explanation for the observed configuration of young stars in the Galactic Centre. This marks a significant contribution to a topic of great interest in contemporary astrophysics. The author also shows in his thesis that a secular instability (m = 1 mode) may occur in the embedding spherical cluster of old stars. This increases the richness of possible evolution scenarios of the embedding cluster and may lead to effective feeding of supermassive black holes through tidal disruption of stars on extremely eccentric orbits.
Download or read book Symmetries in Quantum Physics written by U. Fano and published by Elsevier. This book was released on 1996-06-17 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text focuses on the physics of symmetries, developing symmetries and transformations through concrete physical examples and contexts rather than presenting the information axiomatically, mathematically, and abstractly. Readers are introduced gradually to advanced mathematical procedures, including the Wigner and Racah algebras and their applications to various symmetry groups. The book also includes some of the latest research on the use of non-invariance and non-compact groups in the consideration of relativistic and many-particle problems of atoms and nuclei.This book is an updated replacement for the text Irreducible Tensorial Sets (Academic Press, 1959). Parts A and B of the present book grew out of occasional lectures in the intervening decades at the University of Chicago, where it became neccessary to update or elaborate upon certain points. Part C has been built more recently to deal with innovations and new information in the field of mathematical physics. The book as a whole develops the subject of symmetry from a physical point of view, allowing students and researchers to gain new insight on their subject. This book can be used both as a text and as a reference by students and scientists in the field.Adapts and extends the earlier Irreducible Tensor Sets (Academic Press, 1959) to classroom useExtends to multi-particle systems and relativityIncludes problems in each chapter for homework assignmentsEmbraces the latest research on non-invariance groups

Download or read book Symmetry in Plants written by Roger V. Jean and published by World Scientific. This book was released on 1998 with total page 900 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with biological, mathematical, descriptive, causal and systemic phyllotaxis. It aims at reflecting the widest possible range of ideas and research closely related to phyllotaxis and contains 30 well illustrated chapters.The book has three parts of equal importance. The first two parts concern data collecting, pattern recognition and pattern generation to which students of phyllotaxis are well accustomed. The third part is devoted to the problem of origins of phyllotactic patterns, giving the field of phyllotaxis the universality it requires to be fully understood.Phyllotaxis-like patterns are found in places where genes are not necessarily present. Part III concerns general comparative morphology, homologies with phyllotactic patterns, and recent trends on evolution that can help to understand phyllotaxis.The distinguished researchers who accepted to participate in the production of this book, strongly contributed to the field of phyllotaxis in the past and have devoted a lot of their time to the fascinating subject coming up with most valuable findings, or are newcomers with original ideas that may be very relevant for the future of the field. The book summarizes and updates their contributions, and promotes new avenues in the treatment of phyllotaxis.This book on mathematical and biological phyllotaxis is the first collective book ever. A landmark in the history of phyllotaxis.

Book excerpt: Progress in Astronautics and Aeronautics, Volume 21: Thermal Design Principles of Spacecraft and Entry Bodies is a collection of technical papers drawn mainly from the American Institute of Aeronautics and Astronautics Third Thermophysics Specialist Conference, held in Los Angeles, California on June 24-26, 1968 This volume is divided into three parts. The first part covers some aspects of thermal processes and design, including thermal analysis, convection, radiation, ablation, and space rocket effects. The second part surveys the remote measurements of the thermophysical and thermal radiation properties and joint conductance, which are critical criteria for space thermal design. The third part focuses on the space environmental effects on thermal coatings. This part deals first with the theory of radiative degradation, followed by a presentation of the laboratory measurements. This part also looks into the results of several flight experiments. This book will be of great value to thermophysicists, space engineers, and designers who are working in the space science fields.
Download or read book The World in Your Head written by Steven M. Lehar and published by Psychology Press. This book was released on 2003-01-30 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The World In Your Head: A Gestalt View of the Mechanism of Conscious Experience represents a bold assault on one of the greatest unsolved mysteries in science: the nature of consciousness and the human mind. Rather than examining the brain and nervous system to see what they tell us about the mind, this book begins with an examination of conscious experience to see what it can tell us about the brain. Through this analysis, the first and most obvious observation is that consciousness appears as a volumetric spatial void, containing colored objects and surfaces. This reveals that the representation in the brain takes the form of an explicit volumetric spatial model of external reality. Therefore, the world we see around us is not the real world itself, but merely a miniature virtual-reality replica of that world in an internal representation. In fact, the phenomena of dreams and hallucinations clearly demonstrate the capacity of the brain to construct complete virtual worlds even in the absence of sensory input. Perception is somewhat like a guided hallucination, based on sensory stimulation. This insight allows us to examine the world of visual experience not as scientists exploring the external world, but as perceptual scientists examining a rich and complex internal representation. This unique approach to investigating mental function has implications in a wide variety of related fields, including the nature of language and abstract thought, and motor control and behavior. It also has implications to the world of music, art, and dance, showing how the patterns of regularity and periodicity in space and time--apparent in those aesthetic domains--reflect the periodic basis set of the underlying harmonic resonance representation in the brain.

Download or read book Shattered Symmetry written by Pieter Thyssen and published by Oxford University Press. This book was released on 2017-01-02 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The standard model of subatomic particles and the periodic table of the atoms have the common goal to bring order in the bewildering chaos of the constituents of matter. Their success relies on the presence of fundamental symmetries in their core. The purpose of the book is to share the admiration for the power and the beauty of these symmetries. The reader is taken on a journey from the basic geometric symmetry group of a circle to the sublime dynamic symmetries that govern the motions of the particles. The trail follows the lines of parentage linking groups upstream to the unitary symmetry of the eightfold way of quarks, and to the four-dimensional symmetry of the hydrogen atom. Along the way the theory of symmetry groups is gradually introduced with special emphasis on graphical representations. The final challenge is to open up the structure of Mendeleev's table which goes beyond the symmetry of the hydrogen atom. Breaking this symmetry to accommodate the multi-electron atoms requires to leave the common ground of linear algebras and explore the potential of non-linearity.
Download or read book Symmetry written by Ruth B. McDowell and published by C&T Publishing Inc. This book was released on 1994-01-01 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, Ruth guides the quiltmaker in exploring and developing truly original designs. She presents 17 new quilts based upon the 17 pattern concepts, and she leads the reader through the fun of applying the concepts to the creation of new quilts. Her students have often called this process the most useful design workshop they have ever taken. For the beginning designer, she presents the possibilities inherent in very simple asymmetric block designs. Each chapter presents a new block design and a new concept, illustrated by a quilt shown in color, with templates, yardage chart, and directions. Each of the new blocks can be used in other symmetries to produce new patterns. And each of the concepts can be applied to thousands of other blocks.
