Download or read book Fivefold Symmetry written by Istv n Hargittai and published by World Scientific. This book was released on 1992 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fivefold symmetry is common in flowers, fruits, molecules, logos, and buildings, but it is a forbidden symmetry in the world of crystals. A few years ago, the so-called quasicrystals were discovered displaying fivefold symmetry, and it caused a minirevolution in crystallography. There has been increased awareness of fivefold symmetry in all domains of human interest ever since. The present book brings together authors and ideas on a common theme from mathematics, the sciences, design, and anthropology to history, literature, and the arts. Its 29 chapters are an offering by scientists and humanists from 13 countries to a broad readership of professionals and laypersons about fivefold symmetry and the areas that are being bridged by this unique concept.

Download or read book Disordered Materials written by Paolo Ossi and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The teaching of solid state physics essentially concerns focusing on crystals and their properties. We study crystals and their properties because of the simple and elegant results obtained from the analysis of a spatially periodic system; this is why the analysis can be made considering a small set of atoms that represent the whole system of many particles. In contrast to the formal neat approach to crystals, the study of str- turally disordered condensed systems is somewhat complicated and often leads to relatively imprecise results, not to mention the experimental and computational e?ort involved. As such, almost all university textbooks, - cluding the advanced course books, only brie?y touch on the physics of am- phous systems. In any case, both the fundamental aspect and the ever wider industrial applications have given structurally disordered matter a role that should not be overlooked. The study of amorphous solids and their structure, stability and properties is a vibrant research branch; it is di?cult to imagine how any physicist, chemist or engineer who has to deal with materials could possibly ignore this class of systems.

Download or read book In Our Own Image written by Istvan Hargittai and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The title of our volume refers to what is well described by the following two quota tions:"Godcreated man in his own image"l and "Man creates God in his own image."2 Our approach to symmetry is subjective, and the term "personal" symmetry reflects this approach in our discussion of selected scientific events. We have chosen six icons to symbolize six areas: Kepler for modeling, Fuller for new molecules, Pauling for helical structures, Kitaigorodskii for packing, Bernal for quasicrystals, and Curie for dissymmetry. For the past three decades we have been involved in learning, thinking, speaking, and writing about symmetry. This involvement has augmented our principal activities in molecular structure research. Our interest in symmetry had started with a simple fascination and has evolved into a highly charged personal topic for us. At the start of this volume, we had had several authored and edited symmetry related books behind 3 us. We owe a debt of gratitude to the numerous people whose interviews are quoted 4 in this volume. We very much appreciate the kind and gracious cooperation of Edgar J. Applewhite (Washington, DC), Lawrence S. Bartell (University of Michigan), R.

Download or read book The Golden Ratio And Fibonacci Numbers written by Richard A Dunlap and published by World Scientific. This book was released on 1997-12-16 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this invaluable book, the basic mathematical properties of the golden ratio and its occurrence in the dimensions of two- and three-dimensional figures with fivefold symmetry are discussed. In addition, the generation of the Fibonacci series and generalized Fibonacci series and their relationship to the golden ratio are presented. These concepts are applied to algorithms for searching and function minimization. The Fibonacci sequence is viewed as a one-dimensional aperiodic, lattice and these ideas are extended to two- and three-dimensional Penrose tilings and the concept of incommensurate projections. The structural properties of aperiodic crystals and the growth of certain biological organisms are described in terms of Fibonacci sequences.

Download or read book Designing the Molecular World written by Philip Ball and published by Princeton University Press. This book was released on 2020-10-06 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the most exciting scientific developments in recent years have come not from theoretical physicists, astronomers, or molecular biologists but instead from the chemistry lab. Chemists have created superconducting ceramics for brain scanners, designed liquid crystal flat screens for televisions and watch displays, and made fabrics that change color while you wear them. They have fashioned metals from plastics, drugs from crude oil, and have pinpointed the chemical pollutants affecting our atmosphere and are now searching for remedies for the imperiled planet. Philip Ball, an editor for the prestigious magazine Nature, lets the lay reader into the world of modern chemistry. Here, for example, chemists find new uses for the improbable buckminsterfullerene molecules--60-atom carbon soccerballs, dubbed "buckyballs"--which seem to have applications for everything from lubrication to medicine to electronics. The book is not intended as an introduction to chemistry, but as an accessible survey of recent developments throughout many of the major fields allied with chemistry: from research in traditional areas such as crystallography and spectroscopy to entirely new fields of study such as molecular electronics, artificial enzymes, and "smart" polymer gels. Ball's grand tour along the leading edge of scientific discovery will appeal to all curious readers, with or without any scientific training, to chemistry students looking for future careers, and to practicing chemical researchers looking for information on other specialties within their discipline.

Download or read book Crystal Quasicrystal Transitions written by M.J. Yacamán and published by Elsevier. This book was released on 1993-03-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of five-fold diffraction symmetry by D. Schechtman in 1985 shocked crystallography to its roots. Incommensurable modulation of a crystal changes former identical unit cells into different ones. This radical revolution has given rise to the study of an entirely new class of matter, the quasicrystalline materials. The study of these quasi-periodic crystals brings a unique elucidation of the fundaments of crystallography and the relationship between lattice structure and macroscopic properties. This book covers the transitions between the crystalline and the quasicrystalline state. A thorough understanding of the transition from quasiperiodic to periodic lattices is essential in order to investigate the uniqueness of quasicrystals. In this well-written volume, an overview is given of the most important problems in quasicrystallography today. Leading experts provide insight into recent experimental advances achieved by studying the phase transitions between crystalline and quasicrystalline states. In the theoretical chapters one is introduced to the depth of insight into the nature of crystallography which has arisen through a rigorous understanding of the quasicrystal structure. This book is an essential source of reference for crystallographers, crystal growers and solid state physicists working in the field.

Download or read book In Search of Sir Thomas Browne The Life and Afterlife of the Seventeenth Century s Most Inquiring Mind written by Hugh Aldersey-Williams and published by W. W. Norton & Company. This book was released on 2015-06-15 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extraordinary life and ideas of one of the greatest—and most neglected—minds in history. Sir Thomas Browne (1605–1682) was an English writer, physician, and philosopher whose work has inspired everyone from Ralph Waldo Emerson to Jorge Luis Borges, Virginia Woolf to Stephen Jay Gould. In an intellectual adventure like Sarah Bakewell's book about Montaigne, How to Live, Hugh Aldersey-Williams sets off not just to tell the story of Browne's life but to champion his skeptical nature and inquiring mind. Mixing botany, etymology, medicine, and literary history, Aldersey-Williams journeys in his hero's footsteps to introduce us to witches, zealots, natural wonders, and fabulous creatures of Browne's time and ours. We meet Browne the master prose stylist, responsible for introducing hundreds of words into English, including electricity, hallucination, and suicide. Aldersey-Williams reveals how Browne’s preoccupations—how to disabuse the credulous of their foolish beliefs, what to make of order in nature, how to unite science and religion—are relevant today. In Search of Sir Thomas Browne is more than just a biography—it is a cabinet of wonders and an argument that Browne, standing at the very gates of modern science, remains an inquiring mind for our own time. As Stephen Greenblatt has written, Browne is "unnervingly one of our most adventurous contemporaries."
