Een nieuwe kijk op het binnenste van onze planeetIedereen kent Jules Verne’s Naar het middelpunt van de aarde. Deze roman was gebaseerd op de laatste inzichten uit de geologie, maar sloeg de plank toch behoorlijk mis. De diepste boring in de aardkost is circa 12 kilometer diep, slechts 0.1% van de diameter van de Aarde. Anderhalve eeuw na het verschijnen van ‘Naar het middelpunt van de aarde’ weten we weliswaar al veel meer over de aardkorst, maar zijn de aardmantel en aardkern nog steeds een terra incognita.Op grond van onze huidige kennis en inzichten, nemen Rob de Meijer en Wim van Westrenen u als terranauten après la lettre mee naar het middelpunt van de Aarde. In het boek beschrijven zij de verschijnselen en eigenschappen van diverse delen van het binnenste van onze planeet: de bewegende delen van de korst, de stroming van gesteenten in de mantel, en de vloeibare en vaste delen van de ijzer-nikkelkern. Op de grens van mantel en kern stuiten ze op een grote verrassing: een gigantische, natuurlijke kerncentrale. Zo’n reactor zou volgens de auteurs ook het ontstaan van de Maan kunnen verklaren. Miljarden jaren geleden is een natuurlijke kernreactor ‘kritisch’ geworden, bij de hitte die daarbij ontstond, is een stuk van onze planeet weggeslagen: onze Maan. Vervolgens komen de onderliggende processen en de manier waarop informatie over de wereld onder onze voeten wordt verkregen aan de orde. Ten slotte wordt de Aarde vergeleken met andere planeten in ons zonnestelsel. Een baanbrekende nieuwe visie op de Aarde en de Maan.

This book is a rigorous introduction to the characterization of composite materials by means of ultrasonic waves. Composites are treated here not simply as uniform media, but as inhomogeneous layered anisotropic media with internal structure characteristic of composite laminates. The objective here is to concentrate on exposing the singular behavior of ultrasonic waves as they interact with layered, anisotropic materials, materials which incorporate those structural elements typical of composite laminates. This book provides a synergistic description of both modeling and experimental methods in addressing wave propagation phenomena and composite property measurements. After a brief review of basic composite mechanics, a thorough treatment of ultrasonics in anisotropic media is presented, along with composite characterization methods. The interaction of ultrasonic waves at interfaces of anisotropic materials is discussed, as are guided waves in composite plates and rods. Waves in layered media are developed from the standpoint of the "Stiffness Matrix", a major advance over the conventional, potentially unstable Transfer Matrix approach.Laminated plates are treated both with the stiffness matrix and using Floquet analysis. The important influence on the received electronic signals in ultrasonic materials characterization from transducer geometry and placement are carefully exposed in a dedicated chapter. Ultrasonic wave interactions are especially susceptible to such influences because ultrasonic transducers are seldom more than a dozen or so wavelengths in diameter. The book ends with a chapter devoted to the emerging field of air-coupled ultrasonics. This new technology has come of age with the development of purpose-built transducers and electronics and is finding ever wider applications, particularly in the characterization of composite laminates.

The world is made up of structures too small to see with the naked eye, too small to see even with an electron microscope. Einstein established the reality of atoms and molecules in the early 1900s. How can we see a world measured in fractions of nanometers? (Most atoms are less than one nanometer, less than one-billionth of a meter, in diameter.) This beautiful and fascinating book gives us a tour of the invisible nanoscale world. It offers many vivid color illustrations of atomic structures, each accompanied by a short, engagingly written essay. The structures advance from the simple (air, ice) to the complex (supercapacitator, rare earth magnet). Each subject was chosen not in search of comprehensiveness but because it illustrates how atomic structure creates a property (such as hardness, color, or toxicity), or because it has a great story, or simply because it is beautiful. Thus we learn how diamonds ride volcanoes to the earth's surface (if they came up more slowly, they'd be graphite, as in pencils); what form of carbon is named after Buckminster Fuller; who won in the x-ray vs. mineralogy professor smackdown; how a fuel cell works; when we use spinodal decomposition in our daily lives (it involves hot water and a package of Jell-O), and much more.The amazing color illustrations by Stephen Deffeyes are based on data from x-ray diffraction (a method used in crystallography). They are not just pretty pictures but visualizations of scientific data derived directly from those data. Together with Kenneth Deffeyes's witty commentary, they offer a vivid demonstration of the diversity and beauty found at the nanometer scale.

Neville Price presents a major breakthrough in our understanding of the subject of plate tectonics in this new book. In this ambitious look at the importance of impacts of objects from space on the earth, he challenges the fundamentals of the theory on which geoscience has rested for the past 25 years. In the latter half of the 20th century, earth-scientists gradually became aware of the scale and effect of bombardment by meteoric material on Earth. Prior to 1950 only a handful of small craters were generally accepted as resulting from impact events. Now "e;certain"e; impacts number around 150, with four such features measuring over 100km in diameter.Neville Price evaluates the mechanisms that give rise to plate movements. Generally, such plates move slowly at about the rate-of-growth of human nails and their tracks are usually smooth, gentle curves . Major Impacts and Plate Tectonics presents evidence to show that impacts can cause significant and dramatic changes in track, which cannot be explained by current theories of plate tectonics. The book also demonstrates that such major impact events often coincide with the development of continental flood basalts and oceanic plateau basalts and frequently coincide with major stratigraphic stage boundaries and toxicity, which in turn can be associated with periods of extinction. It concludes that geological history comprises periods of relatively orderly, evolutionary change in Earth and life-forms punctuated by catastrophic changes induced by major impacts that reset the evolutionary clock.

The design of approximation algorithms for spanning tree problems has become an exciting and important area of theoretical computer science and also plays a significant role in emerging fields such as biological sequence alignments and evolutionary tree construction. While work in this field remains quite active, the time has come to collect under one cover spanning tree properties, classical results, and recent research developments.Spanning Trees and Optimization Problems offers the first complete treatment of spanning tree algorithms, from their role in classical computer science to their most modern applications. The authors first explain the general properties of spanning trees, then focus on three main categories: minimum spanning trees, shortest-paths trees, and minimum routing cost spanning trees. Along with the theoretical descriptions of the methods, numerous examples and applications illustrate the concepts in practice. The final chapter explores several other interesting spanning trees, including maximum leaf spanning trees, minimum diameter spanning trees, Steiner trees, and evolutionary trees.With logical organization, well chosen topics, and easy to understand pseudocode, the authors provide not only a full, rigorous treatment of theory and applications, but also an excellent handbook for spanning tree algorithms. This book will be a welcome addition to your reference shelf whether your interests lie in graph and approximation algorithms for theoretical work or you use graph techniques to solve practical problems

There are almost one third of a million species of plants which range in form from unicellular algae a few microns in diameter to gigantic trees that can grow to a height of 100 meters. Plant Life makes sense of the bewildering diversity of plants by treating them not just as photosynthetic factories, but as living organisms that are the survivors of millions of years of evolutionary struggle. The book examines plants from an evolutionary perspective to show how such a wide range of life forms has evolved and continues to thrive.The book is divided into three main sections. The first introductory section sets out the necessary background of evolutionary and taxonomic theory and introduces a classification of living plants based on the ways in which they have evolved. The second part investigates how the challenges of life in the water and on land have led to the evolution of the major taxonomic groups of the plants, and describes the key adaptations that have contributed to the success of each group. The final section shows how the contrasting environments of the world's major climatic zones have led to the evolution of such different floras as those of tropical rainforests, prairies and deserts. This section introduces a fascinating range of plants with ingenious and often bizarre methods of survival and reproduction.The book is enriched by detailed case studies, points for discussion and suggestions for further investigation. In addition, extensive color plates and line drawings bring the world of plants vividly to life. Clear classification charts and a full glossary are also useful.Plant Life is an essential elementary text for undergraduate students and should prove a breath of fresh air for jaded botanists who are accustomed to the traditional taxonomic grind through the plant kingdom.New, environmental approach in keeping with modern course content. Beautifully written in a clear, concise and accessible style. Extensive colour plates, electron micrographs and line drawings bring the world of plants vividly

The theory of random graphs began in the late 1950s in several papers by Erdos and Renyi. In the late twentieth century, the notion of six degrees of separation, meaning that any two people on the planet can be connected by a short chain of people who know each other, inspired Strogatz and Watts to define the small world random graph in which each site is connected to k close neighbors, but also has long-range connections. At a similar time, it was observed in human social and sexual networks and on the Internet that the number of neighbors of an individual or computer has a power law distribution. This inspired Barabasi and Albert to define the preferential attachment model, which has these properties. These two papers have led to an explosion of research. The purpose of this book is to use a wide variety of mathematical argument to obtain insights into the properties of these graphs. A unique feature is the interest in the dynamics of process taking place on the graph in addition to their geometric properties, such as connectedness and diameter.
