Available in PDF, EPUB and Kindle. Book excerpt: This book is based on notes for the course Fractals:lntroduction, Basics and Perspectives given by MichaelF. Barnsley, RobertL. Devaney, Heinz-Otto Peit gen, Dietmar Saupe and Richard F. Voss. The course was chaired by Heinz-Otto Peitgen and was part of the SIGGRAPH '87 (Anaheim, California) course pro gram. Though the five chapters of this book have emerged from those courses we have tried to make this book a coherent and uniformly styled presentation as much as possible. It is the first book which discusses fractals solely from the point of view of computer graphics. Though fundamental concepts and algo rithms are not introduced and discussed in mathematical rigor we have made a serious attempt to justify and motivate wherever it appeared to be desirable. Ba sic algorithms are typically presented in pseudo-code or a description so close to code that a reader who is familiar with elementary computer graphics should find no problem to get started. Mandelbrot's fractal geometry provides both a description and a mathemat ical model for many of the seemingly complex forms and patterns in nature and the sciences. Fractals have blossomed enormously in the past few years and have helped reconnect pure mathematics research with both natural sciences and computing. Computer graphics has played an essential role both in its de velopment and rapidly growing popularity. Conversely, fractal geometry now plays an important role in the rendering, modelling and animation of natural phenomena and fantastic shapes in computer graphics.

Download or read book Ultraviolet Astronomy and the Quest for the Origin of Life written by Ana I. Gomez de Castro and published by Elsevier. This book was released on 2021-03-27 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultraviolet Astronomy and the Quest for the Origin of Life addresses the use of astronomical observations in the ultraviolet range to better understand the generation of complex, life-precursor molecules. The origin of RNA is still under debate but seems to be related to the generation of pools of complex organic molecules submitted to heavy cycles of solution in water and drying. This book investigates whether these cycles require a planetary surface or may occur in space by examining both the theoretical and observational aspects of the role of UV radiation in the origin of life. This book offers the latest advances in these studies for astronomers, astrobiologists and planetary scientists. - Addresses both the theoretical and observational aspects of the role of Ultraviolet (UV) radiation in the origin of life - Builds on the requirements to produce prebiotic molecules in space and the implications for the origin of RNA - Investigates the use of ultraviolet observations related to planetary system formation, the evolution of young planetary disks, and the interaction of stars with planetary atmospheres

Download or read book Physics and Chemistry of Comets written by Walter F. Huebner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: As this excellent book demonstrates, the study of comets has now reached the fas cinating stage where we understand comets in general simple tenns while, at the same time, we are uncertain about practically all the details of cometary nature, structure, processes, and origin. In every aspect, even including dynamics, a choice among several or many competing theories is made impossible simply by the lack of detailed knowledge. The space missions, snapshot studies of two comets, partic ularly the one that immortalizes the name of Sir Edmund Halley, have produced a huge mass of valuable new infonnation and a number of surprises. Nonetheless, we face the tantalizing realization that we have obtained only a fleeting glance at two of perhaps a hundred billion (lOll) or more comets with possibly differing natures, origins, and physical histories. To my personal satisfaction, comets seem to have discrete nuclei made up of dirty snowballs, as I concluded four decades ago, but perhaps they are more like frozen rubbish piles.

Download or read book Molecular Clouds as Probes of Milky Way Structure and Interstellar Turbulence written by Julia Duval and published by . This book was released on 2010 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Galactic Ring Survey, a 13 CO survey of the first quadrant of the Milky Way, is used to probe the spiral structure of the Galaxy and to constrain the formation and turbulent structure of molecular clouds. A sample of 829 molecular clouds has been identified in the Galactic Ring Survey (GRS). Kinematic distances to 750 of these GRS clouds are derived. The Galactic surface mass density of molecular gas is subsequently computed from 13 CO and 12 CO emission detected in the GRS and the University of Massachusetts-Stony Brook surveys. The Galactic distribution of molecular clouds is strongly enhanced along the Scutum-Crux, Sagittarius, and Perseus arms. These molecular data are consistent with a four-arm model of the Galaxy, while the locations of the Scutum-Crux and Perseus arms are consistent with the distribution of the old stellar population inferred from infrared maps. Physical properties of molecular clouds such as size, mass, and density, are also derived in order to compare clouds located inside and outside spiral arms, and to constrain formation models. Molecular clouds located inside inferred spiral arms are found to be more massive, to have higher surface mass densities, and to be more strongly gravitationally bound than inter-arm clouds. This supports cloud formation models involving spiral structure and suggests that molecular clouds must have lifetimes of a few million years. The turbulent structure of molecular clouds is a fundamental component of star formation. The GRS is the first large scale, fully sampled 13 CO survey of the Galaxy allowing the observation of the sub-parsec-scale structure of molecular clouds. Principal Component Analysis applied to both GRS clouds and numerical simulations allows the derivation of turbulent energy spectra over scales ranging from 0.1 pc to 50 pc. The slope of the energy spectrum, E(k), versus the wavenumber, k, obtained for the GRS clouds is consistent with compressible, intermittent turbulence. The slopes and amplitudes of the energy spectra of the clouds are fairly constant over three decades of masses, which indicates that turbulence is driven on large scales by an external, Galactic pool of kinetic energy.
