Fourier's discovery that almost any signal could be built out of basic sine waves, was years ahead of its time. The Fourier Series, and its later developments: the Fourier Transform and the Fast Fourier Transform, lie at the heart of so many of our electronic devices today. From the mobile phone sitting in your pocket, to early warning systems that keep aircraft engines running safely, Fourier is there, telling you which sine waves are present in your signal.
The standard approach to teaching complicated mathematical concepts in schools and universities relies more on mathematical analysis and the student's capability to manipulate equations, than on his or her intuition. A good diagram and a clear analogy are often worth a thousand words.
This book will guide you systematically, visually, and intuitively through each of the core concepts making up the Fourier Series; granting you the knowledge you need to confidently use one of the cornerstones of signal analysis.
Teaching History Today is about placing inquiry, primary sources, and literacy foundations of history instruction front and center in the education Readers can learn how to organize historical content into effective units, integrate the learning of content with development of skills, and gain expertise into engaging students collaboratively.
From the Internet to networks of friendship, disease transmission, and even terrorism, the concept--and the reality--of networks has come to pervade modern society. But what exactly is a network? What different types of networks are there? Why are they interesting, and what can they tell us? In recent years, scientists from a range of fields--including mathematics, physics, computer science, sociology, and biology--have been pursuing these questions and building a new science of networks. This book brings together for the first time a set of seminal articles representing research from across these disciplines. It is an ideal sourcebook for the key research in this fast-growing field.
The book is organized into four sections, each preceded by an editors' introduction summarizing its contents and general theme. The first section sets the stage by discussing some of the historical antecedents of contemporary research in the area. From there the book moves to the empirical side of the science of networks before turning to the foundational modeling ideas that have been the focus of much subsequent activity. The book closes by taking the reader to the cutting edge of network science--the relationship between network structure and system dynamics. From network robustness to the spread of disease, this section offers a potpourri of topics on this rapidly expanding frontier of the new science.Provides a concise up-to-date introduction to and overview of black nationalism in American history
This analytical introduction assesses contrasting definitions of black nationalism in America, thereby providing an overview of its development and varied manifestations across two centuries. Its aim is to evaluate historiographical debates and synthesize a broad range of scholarship, much of it published since the beginning of the new millennium. However, unlike some of that work, this book offers a critical perspective that avoids advocacy or condemnation of black nationalism by examining major black nationalist thinkers, leaders and organizations as well as discussing some lesser-known groups and figures, the nature of black nationalism's appeal and the position of women in and their contributions to black nationalism.
Key Features
Considers divergent definitions of black nationalism, providing an understanding of the nature of black nationalismOutlines historiography with an up-to-date assessment of key debates and leading scholarshipConsiders continuity, encouraging discussion of whether black nationalism was essentially unchanging or reflective of particular historical circumstancesLooks beyond leading figures to understand how, why and when black nationalism gained support
Mark Newman outlines the range of white responses to the Civil Rights Movement and analyses both northern and southern opinion. He examines the role of the federal government, the church and organized labor, as well as the impact of the Cold War. The book discusses local, regional, and national civil rights campaigns; the utility of nonviolent direct action; and the resurgence of Black Nationalism. And it explains the development, achievements and disintegration of the national civil rights coalition, the role of Martin Luther King Jr. and the contribution of many otherwise ordinary men and women to the movement.
The National Association for the Advancement of Colored People receives particular attention, with contrasts drawn between the national office and state conferences and local branches. In detailing and assessing the African-American struggle between the 1930s and 1980s, Newman widens the movement's traditional chronology, offering readers a broad-ranging history.Although much has been written about the golden days of radio, Entrepreneurs of Profit and Pride is the first book to examine the black radio industry. This book traces the development of black radio programming which began when the concept of black appeal first occured to certain entrepreneurs, a concept that played a pivotal role in the rise of cultural pride and soul. Through the case studies of three representative black radio stations, Newman reveals the evolution of programming practices dictated not only by pride but by profits gained through successful marketing. A unique feature of this book is the inclusion of business considerations into a cultural analysis of the medium.
The book begins with a discussion of how poor communications to black audiences in early network broadcasting led to the creation of black-appeal narrowcasting. The author probes the patterns of development in black programming and assesses the impact of that programming on soul consciousness. In addition, the book discusses individuals in the history of black radio, marketing to a minority audience, and the role of media in society as a seller of products and culture.
