Guillermo Gonzalez – författare

The long-awaited second edition of this well-received textbook gives a thorough introduction to observational astronomy. Starting with the basics of positional astronomy and systems of time, it continues with charts and catalogs covering both historically important publications and modern electronic databases. The book builds on a fundamental discussion of the basics of light and the effects of the atmosphere on astronomical observations. Chapters include discussions of optical telescopes, detectors, photometry, variable stars, astrometry, spectroscopy, and solar observations. This edition contains new discussions of measurements with CCDs and appendices give basic statistical methods, useful astronomical software and websites, and sources of accurate time-calibration signals. Observational Astronomy is the perfect textbook for upper level undergraduate or beginning graduate courses on astronomy. Examples based on real astronomical data are placed throughout the text. Each of the well-illustrated chapters is supported by a set of graduated problems and suggestions for further reading.

This textbook provides a solid foundation into many approaches that are used in the analysis of advanced electromagnetic wave propagation problems. The techniques discussed are essential to obtain closed-form solutions or asymptotic solutions and meet an existing need for instructors and students in electromagnetic theory. The book covers various advanced mathematical methods used in the evaluation of the electromagnetic fields in rectangular, cylindrical and spherical geometries. The mathematics of special functions (i.e., Bessel, Hankel, Airy, Legendre, Error, etc.) are covered in depth, including appropriate Appendices. The author takes particular care to provide detailed explanations of auxiliary potentials, Hertz’s vectors, Debye potentials, as well as the use of Green functions, the Watson transformation and the method of steepest descent in the solution of electromagnetic problems. Overall, Advanced Electromagnetic Wave Propagation Methods is a good source for the many skills required in obtaining closed form and asymptotic solution, which in many instances cannot be obtained using computer codes of Maxwell’s equations. Thus, it provides an excellent training for preparing graduate students in their research work. This book is intended for a graduate course in electromagnetic theory for students in electrical engineering. Students in physics and professionals will also find it appropriate and useful.

Este libro trata sobre las observaciones del Dr. Guillermo Gonzlez en relacin al desarrollo de la personalidad colonizada en Puerto Rico. Este tipo de personalidad ha sido descrito anteriormente por otros psiquiatras y psiclogos ampliamente en la literatura mundial, pero nunca en Puerto Rico. Este tipo de personalidad se desarrolla en el individuo a consecuencia de vivir prolongadamente en las distintas colonias que se reconocen internacionalmente. La definicin de una colonia utilizada en este libro es la que oficialmente utiliza la Organizacin de las Naciones Unidas (ONU) en su Comit de Descolonizacin. El libro intenta corregir vacos y deficiencias de informacin en relacin al situacin objetiva de Puerto Rico y los puertorriqueos. En relacin a Puerto Rico, en 1952 la ONU sac incorrectamente a Puerto Rico de su listado de colonias. Esta decisin fue incorrecta, pues con la creacin del Estado Libre Asociado, conocido en los EEUU como Commonwealth of Puerto Rico, el ttulo de propiedad de Puerto Rico todava reside en los EEUU, segn el Tratado de Pars de 1898. Desde entonces y hasta el presente, Puerto Rico es gobernado mediante decretos de los presidentes y leyes elaboradas en el Congreso de los EEUU. Esta admisin de hechos est oficialmente descrita en el informe del presidente Obama de 2011. En Noviembre 6 del 2012 se celebrar un plebiscito sobre el status de las relaciones con los EEUU. El autor describe en su libro cmo la personalidad colonizada en los puertorriqueos influenciar y decidir la eleccin plebiscitaria en Puerto Rico.

The Provocative Classic The Privileged Planet in a Fully Revised, 20th Anniversary Edition! Are we just an accident of cosmic evolution? Is Earth a “lonely speck in the great enveloping cosmic dark” as the late Carl Sagan put it? Or is there more to the story? In this provocative book, Guillermo Gonzalez and Jay W. Richards marshal a staggering array of scientific evidence to counter the modern dogma that Earth is nothing more than the winner of a blind cosmic lottery.   When The Privileged Planet was first published in 2004, it garnered both praise and rage. But its argument has stood the test of time. In this completely revised 20th anniversary edition, Gonzalez and Richards show how thousands of discoveries of extrasolar planets over the last two decades have only strengthened their case.   They take readers on a mind-expanding journey through our solar system and beyond. Along the way, they explore the mystery of total solar eclipses, the crucial role of water and carbon, the fine-tuning of physics that makes advanced life possible, and the beginning of cosmic time. From our cozy blue planet to the edge of the known universe, they show how earthlike planets are exquisitely fit not only to sustain life but to provide the best platform to discover the hidden wonders of the cosmos.  The Privileged Planet compels us to reconsider our place in the universe. Far from a cosmic fluke, our world is ingeniously designed not just for life but for discovery.
