This book is the first of its kind devoted to the key role played by light and electromagnetic radiation in the universe. Readers are introduced to philosophical hypotheses such as the economy, symmetry and the universality of natural laws, and are then guided to practical consequences such as the rules of geometrical optics and even Einstein's well-known but mysterious relationship, E = mc2. Most chapters feature a pen picture of the life and character of a relevant scientific figure. These ‘Historical Interludes’ include, among others, Galileo's conflicts with the Inquisition, Fourier's taunting of the guillotine, Neils Bohr and World War II, and the unique character of Richard Feynman.

All of science springs from the observation of nature.In this classic book, the late Marcel Minnaert accompanies the reader on a tour of nature's light and color and reveals the myriad phenomena that may be observed outdoors with no more than a pair of sharp eyes and an enquiring mind.

“Our voices scrubbed out and forgotten. There are those who research and write about sex workers who often forget we are human.” —Amy Lebovitch Shawna Ferris gives a voice to sex workers who are often pushed to the background, even by those who fight for them. In the name of urban safety and orderliness, street sex workers face stigma, racism, and ignorance. Their human rights are ignored, and some even lose their lives. Ferris aims to reveal the cultural dimensions of this discrimination through literary and art-critical theory, legal and sociological research, and activist intervention. Canadian cities are striving for high safety ratings by eliminating crime, which includes “cleaning” urban areas of the street sex industry. Ironically, sex workers also want to live and work in a safe environment. Ferris questions these sanitizing political agendas, reviews exclusionary legislative and police initiatives, and examines media representations of sex workers. This book has much to offer to educators and activists, sex workers and anti-violence organizations, and academics studying women, cultural, gender, or indigenous issues. Foreword by Amy Lebovitch.

It is common knowledge that if the Sun suddenly turned into a black hole, it would suck Earth and the rest of the planets into oblivion. Yet as bestselling author and astrophysicist Jeffrey Bennett points out, black holes don't suck. With that simple idea in hand, Bennett begins an entertaining introduction to Einstein's theories, describing the amazing phenomena readers would actually experience if they took a trip through a black hole. The theory of relativity also gives us the cosmic speed limit of the speed of light, the mind-bending ideas of time dilation and curvature of spacetime, and what may be the most famous equation in history: e = mc2. Indeed, the theory of relativity shapes much of our modern understanding of the universe, and it is not \"just a theory:\" every major prediction of relativity has been tested to exquisite precision and its practical applications include the Global Positioning System (GPS). Bennett proves anyone can understand the basics of Einstein's ideas. His intuitive, nonmathematical approach gives a wide audience its first real taste of how relativity works and why it is so important not only to science but also to the way we view ourselves as human beings.

With the publication in 1994 of Atomic, Molecular, and Optical Science: An Investment in the Future (the FAMOS report), the National Research Council launched the series Physics in a New Era, its latest survey of physics. Each of the six area volumes in the survey focuses on a different subfield of physics, describing advances since the last decadal survey and suggesting future opportunities and directions. This survey culminated in 2001 with the publication of the seventh and final volume, Physics in a New Era: An Overview. Since the publication of the FAMOS report, the developments in atomic, molecular, and optical (AMO) science have been amazing. Significant advances in areas such as cooling and trapping, atom and quantum optics, single-atom and single-molecule detection, and ultrafast and ultra intense phenomena, along with the emergence of new applications, made it clear that an update of the FAMOS report was needed. With support from the National Science Foundation and the Department of Energy, the Committee for an Updated Assessment of Atomic, Molecular, and Optical Science was formed. The committee's statement of task reads as follows: The committee will prepare a narrative document that portrays the advances in AMO science and its impact on society. This report highlights selected forefront areas of AMO science, emphasizing recent accomplishments and new opportunities, identifies connections between AMO science and other scientific fields, emerging technologies, and national needs, describes career opportunities for AMO scientists. To accomplish its task and at the same time reach a broad audience, the committee decided to present its report in the form of a brochure highlighting selected advances, connections, and impacts on national needs. An exhaustive assessment of the field, which will fall within the purview of the next decadal survey, was not the goal of the update. The committee would like to express its gratitude for the informative interactions it had with many scientists and policy makers. Many colleagues completed a questionnaire and suggested topics to be included in this report. The final selection of topics was made in accordance with the criteria set forth in the statement of task. While this report was still being written, the tragic events of September 11, 2001, occurred. AMO science and its applications have already played and will continue to play a central role in our nation's response to terrorist threats from conventional as well as chemical or biological weapons. Some of the technology discussed in this report in the chapter \"AMO Science Enhancing National Defense\" was used successfully for the U.S. military response in Afghanistan-the Global Positioning System (GPS) and laser-guided munitions are just two examples. AMO science will also enable the development of early detection techniques that will help to neutralize the threat from biological and chemical agents.

For nearly a decade, Brazil has surpassed Thailand as the world's premier sex tourism destination. As the first full-length ethnography of sex tourism in Brazil, this pioneering study treats sex tourism as a complex and multidimensional phenomenon that involves a range of activities and erotic connections, from sex work to romantic transnational relationships. Erica Lorraine Williams explores sex tourism in the Brazilian state of Bahia from the perspectives of foreign tourists, tourism industry workers, sex workers who engage in liaisons with foreigners, and Afro-Brazilian men and women who contend with foreigners' stereotypical assumptions about their licentiousness. She shows how the Bahian state strategically exploits the touristic desire for exotic culture by appropriating an eroticized blackness and commodifying the Afro-Brazilian culture in order to sell Bahia to foreign travelers.
