The Production and Distribution of Knowledge in the United States - Fritz Machlup - Bog - Princeton University Press - Plusbog.dk

The Production and Distribution of Knowledge in the United States marked the beginning of the study of our postindustrial information society. Austrian-born economist Fritz Machlup had focused his research on the patent system, but he came to realize that patents were simply one part of a much bigger "knowledge economy." He then expanded the scope of his work to evaluate everything from stationery and typewriters to advertising to presidential addresses--anything that involved the activity of telling anyone anything. The Production and Distribution of Knowledge in the United States then revealed the new and startling shape of the U.S. economy. Machlup''s cool appraisal of the data showed that the knowledge industry accounted for nearly 29 percent of the U.S. gross national product, and that 43 percent of the civilian labor force consisted of knowledge transmitters or full-time knowledge receivers. Indeed, the proportion of the labor force involved in the knowledge economy increased from 11 to 32 percent between 1900 and 1959--a monumental shift. Beyond documenting this revolution, Machlup founded the wholly new field of information economics. The transformation to a knowledge economy has resonated throughout the rest of the century, especially with the rise of the Internet. As two recent observers noted, "Information goods--from movies and music to software code and stock quotes--have supplanted industrial goods as the key drivers of world markets." Continued study of this change and its effects is testament to Fritz Machlup''s pioneering work.

Hot Molecules, Cold Electrons - Paul J. Nahin - Bog - Princeton University Press - Plusbog.dk

Hot Molecules, Cold Electrons - Paul J. Nahin - Bog - Princeton University Press - Plusbog.dk

An entertaining mathematical exploration of the heat equation and its role in the triumphant development of the trans-Atlantic telegraph cable Heat, like gravity, shapes nearly every aspect of our world and universe, from how milk dissolves in coffee to how molten planets cool. The heat equation, a cornerstone of modern physics, demystifies such processes, painting a mathematical picture of the way heat diffuses through matter. Presenting the mathematics and history behind the heat equation, Hot Molecules, Cold Electrons tells the remarkable story of how this foundational idea brought about one of the greatest technological advancements of the modern era.Paul Nahin vividly recounts the heat equation’s tremendous influence on society, showing how French mathematical physicist Joseph Fourier discovered, derived, and solved the equation in the early nineteenth century. Nahin then follows Scottish physicist William Thomson, whose further analysis of Fourier’s explorations led to the pioneering trans-Atlantic telegraph cable. This feat of engineering reduced the time it took to send a message across the ocean from weeks to minutes. Readers also learn that Thomson used Fourier’s solutions to calculate the age of the earth, and, in a bit of colorful lore, that writer Charles Dickens relied on the trans-Atlantic cable to save himself from a career-damaging scandal. The book’s mathematical and scientific explorations can be easily understood by anyone with a basic knowledge of high school calculus and physics, and MATLAB code is included to aid readers who would like to solve the heat equation themselves.A testament to the intricate links between mathematics and physics, Hot Molecules, Cold Electrons offers a fascinating glimpse into the relationship between a formative equation and one of the most important developments in the history of human communication.

The Bronx Nobody Knows - William B. Helmreich - Bog - Princeton University Press - Plusbog.dk

The Bronx Nobody Knows - William B. Helmreich - Bog - Princeton University Press - Plusbog.dk

A neighborhood-by-neighborhood guide to New York City’s northern borough, from the award-winning author of The New York Nobody KnowsBill Helmreich walked every block of New York City—some six thousand miles—to write the award-winning The New York Nobody Knows. Later, he re-walked most of the Bronx to create this one-of-a-kind walking guide to the city’s northern borough, from Mott Haven to City Island. Drawing on hundreds of conversations he had with residents during his block-by-block journey through this fascinating, diverse, and underappreciated borough, Helmreich highlights hundreds of facts and points of interest that you won’t find in any other guide. In the West Bronx, you’ll discover the spot where DJ Cool Herc is believed to have given birth to hip hop in 1973, at a party on Sedgwick Avenue overlooking the Harlem River. In Concourse East, once home to a vibrant Jewish community, you will learn about a beautiful, perfectly preserved, hidden synagogue. In Allerton, you will visit a family-run Italian bakery where the third-generation owner still makes his own cannoli and uses the original recipe for their famous rainbow cookies. In Pelham Parkway/Pelham Gardens, you will explore the city’s largest park, the stunning 2,700-acre Pelham Bay Park. And much, much more. An unforgettably vivid chronicle of today’s Bronx, the book can be enjoyed without ever leaving home—but it’s almost guaranteed to inspire you to get out and explore this captivating borough. Covers every one of the Bronx’s neighborhoods, providing a colorful portrait of their most interesting, unusual, and unfamiliar people, places, and thingsEach neighborhood section features a brief overview and history; a detailed, user-friendly map keyed to the text; photographs; and a lively guided walking tourDraws on the author’s walk through every Bronx neighborhoodIncludes insights from conversations with hundreds of residents
