The Day the Universe Changed
by James Lee BurkeIn The Day the Universe Changed, James Burke examines eight periods in history when our view of the world shifted dramatically: in the eleventh century, when extraordinary discoveries were made by Spanish crusaders; in fourteenth-century Florence, where perspective in painting emerged; in the fifteenth century, when the advent of the printing press shook the foundations of an oral society; in the sixteenth century, when gunnery developments triggered the birth of modern science; in the early eighteenth century, when hot English summers brought on the Industrial Revolution; in the battlefield surgery stations of the French revolutionary armies, where people first became statistics; in the nineteenth century, when the discovery of dinosaur fossils led to the theory of evolution; and in the 1820s, when electrical experiments heralded the end of scientific certainty. Based on the popular television documentary series, The Day the Universe Changed is a bestselling history that challenges the reader to decide whether there is absolute knowledge to discover - or whether the universe is "ultimately what we say it is."

Daylight Science and Daylighting Technology
by Miroslav Kocifaj Richard Kittler Stanislav DarulaSunlight profoundly influences the Earth's atmosphere and biosphere. Nature fuels the evolution of all living things, their visual systems, and the manner in which they adapt, accommodate, and habituate. Sun luminance measurements serve as data to calculate typical changes in the daily, monthly, and annual variability characteristics of daylight. Climate-based sky luminance patterns are used as models in predicting daylighting calculation and computer programs applied in architecture and building design. Historically, daylight science and daylighting technology has prioritized photometric methods of measurements, calculation, and graphical tools aimed at predicting or evaluating the daylighting of architectural design alternatives. However, due to a heightened awareness of general health and well-being, sunlight exposure and freedom from visual discomfort while undertaking visual tasks are now equally prioritized. Therefore, in order to assure optimal environmental quality, daylighting technology must be based on sound science. Daylight Science and Daylighting Technology, by Richard Kittler, Miroslav Kocifaj, and Stanislav Darula, sketches the entire evolution of daylight science from atmospheric science through apt visual workplace psychophysics.
The Dazzle of the Digital: Unbundling India Online (Routledge Focus on Modern Subjects)
by Vivan Sharan Meghna BalThe Dazzle of the Digital is written in the context of digital technology’s inextricable link with progress and modernity in India, with the COVID pandemic in the backdrop. Digital technology such as smartphones and the internet exemplify the popular ideal of a modernity where the proliferation of data and information seamlessly translates into knowledge and value. The authors attempt to wrestle with this impulsive conflation of the digital with the modern, and argue that the former can sometimes retard progress rather than foster it. They provide examples from various spheres – ranging from public service delivery to private markets – to unpack the pitfalls of a blinkered view on modernity. The book presents an objective take on the potential of digital technology, written with the hope that it will prompt greater societal reflection on technology as a lever for advancement, at a time when the march of everything digital is inexorable.

DC-DC Converter Topologies: Basic to Advanced (IEEE Press)
by Gerry MoschopoulosDC-DC Converter Topologies A comprehensive look at DC-DC converters and advanced power converter topologies for all skills levels As it can be rare for source voltage to meet the requirements of a Direct Current (DC) load, DC-DC converters are essential to access service. DC-DC power converters employ power semiconductor devices (like MOSFETs and IGBTs) as switches and passive elements such as capacitors, inductors, and transformers to alter the voltage provided by a DC source into the necessary DC voltage as is required by a DC load. This source can be a battery, solar panels, fuel cells, or a DC bus voltage fed by rectified AC utility voltage. As the many components of DC-DC converters can be differently arranged into circuit structures called topologies, there are as many possible circuit topologies as there are possible combinations of circuit elements. Focusing on DC-DC switch-mode power converters ranging from 50 W to 10kW, DC-DC Converter Topologies provides a survey of all converter topology types within this power range. General principles are described for each topology type using a representative converter as an example. Variations that can be found that differ from the example are then examined, with a helpful discussion of comparisons when relevant. A broad range of topics is covered within the book, from simple, low-power converters to complex, high-power converters and everywhere in between. DC-DC Converter Topologies readers will also find: A detailed discussion of four key DC-DC converter topologies Description of isolated two-switch pulse-width modulated (PWM) topologies including push-pull, half-bridge, and interleaved converters An exploration of high-gain converters such as coupled inductors, voltage multipliers, and switched capacitor converters This book provides the tools so that a non-expert will be equipped to deal with the vast array of DC-DC converters that presently exist. As such, DC-DC Converter Topologies is a useful reference for electrical engineers, professors, and graduate students studying in the field.

De-Bug: Voices from the Underside of Silicon Valley
by Raj Jayadev and Jean MelesaineStories of the dot-com boom—from everyone but the techies. “A raw look into the lives of residents bearing the brunt of gentrification.” —HuffPostNo shuttle buses here: De-Bug, a new collection of true stories from the social justice organization of the same name, shows a side of working in Silicon Valley that you won’t read about in the business section. As tech moguls land the cover of Forbes, the South Bay’s working class is making ends meet as metal scrappers, factory workers, club bouncers, hairstylists, rickshaw drivers, ice cream cart pushers. The stories in De-Bug are poignant, often very funny accounts of bootstrapping in the land of angel investors and thought leaders. A construction worker predicts which of his customers are about to strike it rich and which are on the edge of bankruptcy based on the states of their swimming pools. A “secondhand hustler” travels the garage sale-flea market circuit in search of treasures to resell online. A temp worker at a medical device manufacturer sells his blood, at the company’s request, to test the equipment. These storytellers are frank when discussing their own flaws, but are equally up-front about the rigged system in which they operate.Disruptive in the truest sense of the word, De-Bug offers valuable insight into California’s latest boomtown.“Silicon Valley’s less-noticed denizens show an unexpected knack for grace, wit, and survival.” —Kentaro Toyama, author of Geek Heresy“If you truly want to know Silicon Valley, in all of its complexity, then De-Bug is a must-read.” —Tomás Jiménez, associate professor of sociology, Stanford University
De-Convergence of Global Media Industries: De-convergence Of Global Media Industries (Routledge Research in Cultural and Media Studies #47)
by Dal Yong JinConvergence has become a buzzword, referring on the one hand to the integration between computers, television, and mobile devices or between print, broadcast, and online media and on the other hand, the ownership of multiple content or distribution channels in media and communications. Yet while convergence among communications companies has been the major trend in the neoliberal era, the splintering of companies, de-convergence, is now gaining momentum in the communications market. As the first comprehensive attempt to analyze the wave of de-convergence of the global media system in the context of globalization, this book makes sense of those transitions by looking at global trends and how global media firms have changed and developed their business paradigm from convergence to de-convergence. Jin traces the complex relationship between media industries, culture, and globalization by exploring it in a transitional yet contextually grounded framework, employing a political economic analysis integrating empirical data analysis.
De-Extinction: The Science of Bringing Lost Species Back to Life
by Rebecca E. HirschIn the twenty-first century, because of climate change and other human activities, many animal species have become extinct, and many others are at risk of extinction. Once they are gone, we cannot bring them back—or can we? With techniques such as cloning, scientists want to reverse extinction and return lost species to the wild. Some scientists want to create clones of recently extinct animals, while others want to make new hybrid animals. Many people are opposed to de-extinction. Some critics say that the work diverts attention from efforts to save species that are endangered. Others say that de-extinction amounts to scientists "playing God." Explore the pros and cons of de-extinction and the cutting-edge science that makes it possible.
