For everyone who has looked up at the stars on a clear nightand longed to know more about them, here is the perfectintroduction and guide to discovering the stars. Discover the Stars leads you on a tour of all the stars andconstellations visible with the naked eye and introduces you todeep-sky objects that can be seen with binoculars or a simpletelescope. The tour is conducted by the editor of Astronomymagazine, Richard Berry, whose two-color, computer-plotted sky mapsand clear instructions make stargazing fun and productive from yourfirst night out. The heart of Discover the Stars is two sections of big, beautifulsky maps and charts. The first section features twelve maps thatshow the entire sky overhead as it appears during each month of theyear. These outline all the constellations visible anywhere in theNorthern Hemisphere, and the accompanying text reveals the richancient mythology that surrounds the star groups. The second section is made up of twenty-three star ch

This rigourous and self-contained book describes mathematicaland, in particular, stochastic methods to assess the performance ofnetworked systems. It consists of three parts. The first part is areview on probability theory. Part two covers the classical theoryof stochastic processes (Poisson, renewal, Markov and queuingtheory), which are considered to be the basic building blocks forperformance evaluation studies. Part three focuses on therelatively new field of the physics of networks. This part dealswith the recently obtained insights that many very different largecomplex networks - such as the Internet, World Wide Web, proteins,utility infrastructures, social networks - evolve and behaveaccording to more general common scaling laws. This understandingis useful when assessing the end-to-end quality of communicationsservices, for example, in Internet telephony, real-time video andinteracting games. Containing problems and solutions, this book isideal for graduate students taking courses in performanceanalys

From Publishers Weekly In this lively volume, Cambridge physicist Barrow (The Book ofNothing) considers the natural constants-the handful of seeminglyeternal numerical values, such as the speed of light, the weight ofthe proton, Planck's constant or the four dimensions of space andtime-that constitute the "bedrock" of physical reality. Theseconstants quantify some of the simplest statements that sciencemakes about the world, but as this fascinating work of popularscience demonstrates, they have profound implications for the fateof the universe and our place within it. And, Barrow hints, theymight not be truly constant. He traces scientists' evolvingunderstanding of the natural constants as they grew to assume acentral role in modern relativity theory and quantum mechanics, andoutlines ongoing attempts to determine whether they are justinexplicable facts of nature or the logical consequence of somefundamental Theory of Everything. He also raises importantphilosophical and even religious questions. The n

The ecological literature on marsupials is dominated byde*ive natural history, and there has hitherto been littleattempt at either synthesis or evolutionary interpretation. Thisbook attempts to provide such a synthesis, by drawing on both thede*ive data base and predictions from the burgeoningliterature on behavioural and evolutionary ecology. It documentsthe excellent potential the study of marsupials provides forresolution of theoretical questions of general importance inbiology. It does this in three ways. First, by describing theimpressive diversity of marsupial life history strategies andtrophic roles. Second, by careful comparison with the eutherians,the scope of the marsupial radiation is used to analyse the role ofdevelopmental constraints and adaptive radiation in determining thediversification of higher taxa. Lastly, it is suggested that theaccessibility of marsupial young during their obligatory pouch lifefacilitates measurement, manipulation and assessment of kinship notpossible in other mammalia

The sustainable exploitation of the marine environment dependsupon our capacity to develop systems of management with predictableoutcomes. Unfortunately, marine ecosystems are highly dynamic andthis property could conflict with the objective of sustainableexploitation. This book investigates the theory that the populationand behavioural dynamics of predators at the upper end of marinefood chains can be used to assist with management. Since thesespecies integrate the dynamics of marine ecosystems across a widerange of spatial and temporal scales, they offer new sources ofinformation that can be formally used in setting managementobjectives. This book examines the current advances in theunderstanding of the ecology of marine predators and willinvestigate how information from these species could be used inmanagement.

From one of the most significant neuroscientists at worktoday, a pathbreaking investigation of a question that hasconfounded philosophers, psychologists, and neuroscientists forcenturies: how is consciousness created? Antonio Damasio has spent the past thirty years studying andwriting about how the brain operates, and his work has garneredacclaim for its singular melding of the scientific and thehumanistic. In Self Comes to Mind, he goes against thelong-standing idea that consciousness is somehow separate from thebody, presenting compelling new scientific evidence thatconsciousness—what we think of as a mind with a self—is to beginwith a biological process created by a living organism. Besides thethree traditional perspectives used to study the mind (theintrospective, the behavioral, and the neurological), Damasiointroduces an evolutionary perspective that entails a radicalchange in the way the history of conscious minds is viewed andtold. He also advances a radical hypothesis regarding the o

There has been an explosive growth in the field ofcombinatorial algorithms. These algorithms depend not only onresults in combinatorics and especially in graph theory, but alsoon the development of new data structures and new techniques foranalyzing algorithms. Four classical problems in networkoptimization are covered in detail, including a development of thedata structures they use and an analysis of their running time.Data Structures and Network Algorithms attempts to provide thereader with both a practical understanding of the algorithms,described to facilitate their easy implementation, and anappreciation of the depth and beauty of the field of graphalgorithms.
