A concise history of how American law has shaped—and been shaped by—the experience of contagion“Contrarians and the civic-minded alike will find Witt’s legal survey a fascinating resource”—Kirkus, starred review “Professor Witt’s book is an original and thoughtful contribution to the interdisciplinary study of disease and American law. Although he covers the broad sweep of the American experience of epidemics from yellow fever to COVID-19, he is especially timely in his exploration of the legal background to the current disaster of the American response to the coronavirus. A thought-provoking, readable, and important work.” - Frank Snowden, author of Epidemics and Society From yellow fever to smallpox to polio to AIDS to COVID-19, |

epidemics have prompted Americans to make choices and answer questions about their basic values and their laws. In five concise chapters, historian John Fabian Witt traces the legal history of epidemics, showing how infectious disease has both shaped, and been shaped by, the law. Arguing that throughout American history legal approaches to public health have been liberal for some communities and authoritarian for others, Witt shows us how history’s answers to the major questions brought up by previous epidemics help shape our answers today: What is the relationship between individual liberty and the common good? What is the role of the federal government, and what is the role of the states? Will long-standing traditions of government and law give way to the social imperatives of an epidemic? Will we let the inequities of our mixed tradition continue? |

Sommario/riassunto |

"Quartz, unique in its chemical, electrical, mechanical, and thermal properties, is used as a frequency control element in applications where stability of frequency is an absolute necessity. Without crystal controlled transmission, radio and television would not be possible in their present form. The quartz crystals allow the individual channels in communication systems to be spaced closer together to make better use of one of most precious resources -- wireless bandwidth. This book describes the characteristics of the art of crystal oscillator design, including how to specify and select crystal oscillators. While presenting various varieties of crystal oscillators, this resource also provides microwave engineers with MathCad and Genesys simulations."-- |
