How Our Place in the Cosmos is Designed for Discovery

The Privileged Planet

Oscillators are an important component in today's RF and microwave systems, and practitioners in the field need to know how to design oscillators for stability and top performance. Offering engineers broader coverage than other oscillator design books on the market, this comprehensive resource considers the complete frequency range, from low-frequency audio oscillators to more complex oscillators found at the RF and microwave frequencies. Packed with over 1,200 equations, the book gives professionals a thorough understanding of the principles and practice of oscillator circuit design and emphasizes the use of time-saving CAD (computer aided design) simulation techniques. From the theory and characteristics of oscillators, to the design of a wide variety of oscillators (including tuned-circuit, crystal, negative-resistance, and relaxation oscillators), this unique book is a one-stop reference practitioners can turn to again and again when working on their challenging projects in this field.

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.

Puerto Rico es un territorio no incorporado de los Estados Unidos de América desde la invasión militar por los Estados Unidos en 1898 en Puerto Rico. Con cuatrocientos cinco años de colonización de España y ciento ocho años por los Estados Unidos, Puerto Rico es la colonia más antigua del mundo. Este es un hecho no conocido por muchos norteamericanos, sorprendentemente tampoco por muchos puertorriqueños. Este libro trata sobre la perspectiva de un psiquiatra sobre este problema. He trabajado por los pasados treinta y tres años en psiquiatría clínica comunitaria tanto en Puerto Rico como New Bedford, Massachussets. Durante este tiempo he podido observar muchas cualidades de la personalidad de los puertorriqueños. He descubierto un tipo de personalidad muy común en los puertorriqueños, la he llamado la Personalidad Colonizada. Este tipo de personalidad es resultado directo de esta experiencia única de ser la colonia más antigua del mundo.

Earth. The Final Frontier Contrary to popular belief, Earth is not an insignificant blip on the universe’s radar. Our world proves anything but average in Guillermo Gonzalez and Jay W. Richards’ The Privileged Planet: How Our Place in the Cosmos Is Designed for Discovery. But what exactly does Earth bring to the table? How does it prove its worth among numerous planets and constellations in the vastness of the Milky Way? In The Privileged Planet, you’ll learn about the world’s: life-sustaining capabilities water and its miraculous makeup protection by the planetary giants And how our planet came into existence in the first place.
