Book excerpt: Light and light based technologies have played an important role in transforming our lives via scientific contributions spanned over thousands of years. In this book we present a vast collection of articles on various aspects of light and its applications in the contemporary world at a popular or semi-popular level. These articles are written by the world authorities in their respective fields. This is therefore a rare volume where the world experts have come together to present the developments in this most important field of science in an almost pedagogical manner. This volume covers five aspects related to light. The first presents two articles, one on the history of the nature of light, and the other on the scientific achievements of Ibn-Haitham (Alhazen), who is broadly considered the father of modern optics. These are then followed by an article on ultrafast phenomena and the invisible world. The third part includes papers on specific sources of light, the discoveries of which have revolutionized optical technologies in our lifetime. They discuss the nature and the characteristics of lasers, Solid-state lighting based on the Light Emitting Diode (LED) technology, and finally modern electron optics and its relationship to the Muslim golden age in science. The book’s fourth part discusses various applications of optics and light in today's world, including biophotonics, art, optical communication, nanotechnology, the eye as an optical instrument, remote sensing, and optics in medicine. In turn, the last part focuses on quantum optics, a modern field that grew out of the interaction of light and matter. Topics addressed include atom optics, slow, stored and stationary light, optical tests of the foundation of physics, quantum mechanical properties of light fields carrying orbital angular momentum, quantum communication, and Wave-Particle dualism in action.

Available in PDF, EPUB and Kindle. Book excerpt: Compared to traditional electrical filaments, arc lamps, and fluorescent lamps, solid-state lighting offers higher efficiency, reliability, and environmentally friendly technology. LED / solid-state lighting is poised to take over conventional lighting due to cost savings—there is pretty much no debate about this. In response to the recent activity in this field, Fundamentals of Solid-State Lighting: LEDs, OLEDs, and Their Applications in Illumination and Displays covers a range of solid-state devices, technologies, and materials used for lighting and displays. It also examines auxiliary but critical requirements of efficient applications, such as modeling, thermal management, reliability, and smart lighting. The book discusses performance metrics of LEDs such as efficiency, efficacy, current–voltage characteristics, optical parameters like spectral distribution, color temperature, and beam angle before moving on to luminescence theory, injection luminescence, radiative and non-radiative recombination mechanisms, recombination rates, carrier lifetimes, and related topics. This lays down the groundwork for understanding LED operation. The book then discusses energy gaps, light emission, semiconductor material, special equipment, and laboratory facilities. It also covers production and applications of high-brightness LEDs (HBLEDs) and organic LEDs (OLEDs). LEDs represent the landmark development in lighting since the invention of electric lighting, allowing us to create unique, low-energy lighting solutions, not to talk about their minor maintenance expenses. The rapid strides of LED lighting technology over the last few years have changed the dynamics of the global lighting market, and LEDs are expected to be the mainstream light source in the near future. In a nutshell, the book traces the advances in LEDs, OLEDs, and their applications, and presents an up-to-date and analytical perspective of the scenario for audiences of different backgrounds and interests.

Download or read book Stakeholder Capitalism written by Klaus Schwab and published by John Wiley & Sons. This book was released on 2021-01-27 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reimagining our global economy so it becomes more sustainable and prosperous for all Our global economic system is broken. But we can replace the current picture of global upheaval, unsustainability, and uncertainty with one of an economy that works for all people, and the planet. First, we must eliminate rising income inequality within societies where productivity and wage growth has slowed. Second, we must reduce the dampening effect of monopoly market power wielded by large corporations on innovation and productivity gains. And finally, the short-sighted exploitation of natural resources that is corroding the environment and affecting the lives of many for the worse must end. The debate over the causes of the broken economy—laissez-faire government, poorly managed globalization, the rise of technology in favor of the few, or yet another reason—is wide open. Stakeholder Capitalism: A Global Economy that Works for Progress, People and Planet argues convincingly that if we don't start with recognizing the true shape of our problems, our current system will continue to fail us. To help us see our challenges more clearly, Schwab—the Founder and Executive Chairman of the World Economic Forum—looks for the real causes of our system's shortcomings, and for solutions in best practices from around the world in places as diverse as China, Denmark, Ethiopia, Germany, Indonesia, New Zealand, and Singapore. And in doing so, Schwab finds emerging examples of new ways of doing things that provide grounds for hope, including: Individual agency: how countries and policies can make a difference against large external forces A clearly defined social contract: agreement on shared values and goals allows government, business, and individuals to produce the most optimal outcomes Planning for future generations: short-sighted presentism harms our shared future, and that of those yet to be born Better measures of economic success: move beyond a myopic focus on GDP to more complete, human-scaled measures of societal flourishing By accurately describing our real situation, Stakeholder Capitalism is able to pinpoint achievable ways to deal with our problems. Chapter by chapter, Professor Schwab shows us that there are ways for everyone at all levels of society to reshape the broken pieces of the global economy and—country by country, company by company, and citizen by citizen—glue them back together in a way that benefits us all.

Download or read book Anthem written by Ayn Rand and published by Ayn Rand Institute Press. This book was released on 2021-07-07 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: About this Edition This 2021-2022 Digital Student Edition of Ayn Rand's Anthem was created for teachers and students receiving free novels from the Ayn Rand Institute, and includes a historic Q&A with Ayn Rand that cannot be found in any other edition of Anthem. In this Q&A from 1979, Rand responds to questions about Anthem sent to her by a high school classroom. About Anthem Anthem is Ayn Rand’s “hymn to man’s ego.” It is the story of one man’s rebellion against a totalitarian, collectivist society. Equality 7-2521 is a young man who yearns to understand “the Science of Things.” But he lives in a bleak, dystopian future where independent thought is a crime and where science and technology have regressed to primitive levels. All expressions of individualism have been suppressed in the world of Anthem; personal possessions are nonexistent, individual preferences are condemned as sinful and romantic love is forbidden. Obedience to the collective is so deeply ingrained that the very word “I” has been erased from the language. In pursuit of his quest for knowledge, Equality 7-2521 struggles to answer the questions that burn within him — questions that ultimately lead him to uncover the mystery behind his society’s downfall and to find the key to a future of freedom and progress. Anthem anticipates the theme of Rand’s first best seller, The Fountainhead, which she stated as “individualism versus collectivism, not in politics, but in man’s soul.”

Download or read book Why Should Anyone Be Led by You written by Robert Goffee and published by Harvard Business Press. This book was released on 2006-02-07 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Too many companies are managed not by leaders, but by mere role players and faceless bureaucrats. What does it take to be a real leader—one who is confident in who she is and what she stands for, and who truly inspires people to achieve extraordinary results? Rob Goffee and Gareth Jones argue that leaders don’t become great by aspiring to a list of universal character traits. Rather, effective leaders are authentic: they deploy individual strengths to engage followers’ hearts, minds, and souls. They are skillful at consistently being themselves, even as they alter their behaviors to respond effectively in changing contexts. In this lively and practical book, Goffee and Jones draw from extensive research to reveal how to hone and deploy one’s unique leadership assets while managing the inherent tensions at the heart of successful leadership: showing emotion and withholding it, getting close to followers while keeping distance, and maintaining individuality while “conforming enough.” Underscoring the social nature of leadership, the book also explores how leaders can remain attuned to the needs and expectations of followers. Why Should Anyone Be Led By You? will forever change how we view, develop, and practice the art of leadership, wherever we live and work.
