Tilted Mirrors


Book Description

"Instead of examining the impact of media on society, Tilted Mirrors explores the impact of society on media. How do communities affect the way media build different issue perspectives or frames? Introducing an unusual composite "Media Vector" score, the book adopts an innovative "community structure" approach, using modern national databases to link selected city characteristics and nationwide newspaper reporting on critical issues. Several media frame-building patterns emerge. The "Buffer Hypothesis" connects larger proportions of privileged groups "buffered" from economic uncertainty in cities to more favorable reporting on human rights claims or scientific advances (e.g., Anita Hill, physician-assisted suicide and embryonic stem cell research). Other frame-building patterns - Violated Buffer, Vulnerability, Protection and Stakeholder - also illuminate critical issues (e.g., banning smoking advertising to children, the Supreme Court stopping presidential vote counting in 2000, capital punishment, Patient's Bill of Rights, gun control, Arctic oil drilling, trying juveniles as adults, gays in the Boy Scouts, and those with HIV/AIDS). Positioned at the crossroads of communication/journalism, political science and sociology disciplines, Tilted Mirrors is a supplemental text for courses in mass media, media effects, communication or journalism research methods, political communication or sociology of communication."--BOOK JACKET.




Lens Design


Book Description

There is no shortage of lens optimization software on the market to deal with today's complex optical systems for all sorts of custom and standardized applications. But all of these software packages share one critical flaw: you still have to design a starting solution. Continuing the bestselling tradition of the author's previous books, Lens Design, Fourth Edition is still the most complete and reliable guide for detailed design information and procedures for a wide range of optical systems. Milton Laikin draws on his varied and extensive experience, ranging from innovative cinematographic and special-effects optical systems to infrared and underwater lens systems, to cover a vast range of special-purpose optical systems and their detailed design and analysis. This edition has been updated to replace obsolete glass types and now includes several new designs and sections on stabilized systems, the human eye, spectrographic systems, and diffractive systems. A new CD-ROM accompanies this edition, offering extensive lens prescription data and executable ZEMAX files corresponding to figures in the text. Filled with sage advice and completely illustrated, Lens Design, Fourth Edition supplies hands-on guidance for the initial design and final optimization for a plethora of commercial, consumer, and specialized optical systems.




Full Tilt


Book Description

Full of roller-coaster twists and turns, Neal Shusterman's page-turner is an Orpheus-like adventure into one boy's psyche. Sixteen-year-old Blake and his younger brother, Quinn, are exact opposites. Blake is the responsible member of the family. He constantly has to keep an eye on the fearless Quinn, whose thrill-seeking sometimes goes too far. But the stakes get higher when Blake has to chase Quinn into a bizarre phantom carnival that traps its customers forever. In order to escape, Blake must survive seven deadly rides by dawn, each of which represents a deep, personal fear--from a carousel of stampeding animals to a hall of mirrors that changes people into their deformed reflections. Blake ultimately has to face up to a horrible secret from his own past to save himself and his brother--that is, if the carnival doesn't claim their souls first!




Principles of Adaptive Optics


Book Description

Since the publication of the second edition of Principles of Adaptive Optics, the developments and applications in this area have increased tremendously. Observatories are now producing outstanding science through adaptive optics technology; components, such as micromachined deformable mirrors and very low noise detectors, are revolutionizing the f







Measuring the Universe


Book Description

A one-stop guide to astronomical instrumentation and data acquisition, with a focus on the underlying principles behind each instrument's operation.




Modern Pictorial Perspective


Book Description

This slim and focused guide to understanding and analyzing perspective in drawing was written by T. Heaton Cooper, a longtime instructor at the Cleveland School of Art. It consists of 50 examples: every left-hand page features a graphic representation of the written descriptions on the opposite page, providing an improved understanding of the concepts via visual examples. Discussions and directions on foreshortening and shadows in relation to perspective complement the illustrations. Students, art teachers, and artists wishing to improve their skills will find this book an ideal resource for study and reference. Its compact size will make it an easy addition to the paint box or sketch kit.




Diffraction-Limited Imaging with Large and Moderate Telescopes


Book Description

This book deals with the fundamentals of wave optics, polarization, interference, diffraction, imaging, and the origin, properties, and optical effects of turbulence in the Earth's atmosphere. Techniques developed during the last few decades to overcome atmospheric image degradation (including passive methods, speckle interferometry in particular, and active methods such as adaptive optics), are highlighted. Also discussed are high resolution sensors, image processing, and the astronomical results obtained with these techniques.




Make It Glow!


Book Description

Presents simple experiments, with step-by-step, illustrated instructions, for studying the science of light, including how rainbows are made and how light can change directions.
