"One of the most mesmerizing and exhilarating, yet alarming modern technology books…an extraordinary tale." —Gillian Tett, Financial Times Pinpoint tells the fascinating story of a hidden system that touches nearly every aspect of modern life. Tracking the development of GPS from its origins as a bomb guidance system to its present ubiquity, Greg Milner examines the technology’s double-edged effect on the way we live, work, and travel. Savvy and original, this sweeping scientific history offers startling insight into how humans understand their place in the world.

One of New York Magazine's best books on Silicon Valley! The true, behind-the-scenes history of the people who built Silicon Valley and shaped Big Tech in America Long before Margaret O'Mara became one of our most consequential historians of the American-led digital revolution, she worked in the White House of Bill Clinton and Al Gore in the earliest days of the commercial Internet. There she saw firsthand how deeply intertwined Silicon Valley was with the federal government--and always had been--and how shallow the common understanding of the secrets of the Valley's success actually was. Now, after almost five years of pioneering research, O'Mara has produced the definitive history of Silicon Valley for our time, the story of mavericks and visionaries, but also of powerful institutions creating the framework for innovation, from the Pentagon to Stanford University. It is also a story of a community that started off remarkably homogeneous and tight-knit and stayed that way, and whose belief in its own mythology has deepened into a collective hubris that has led to astonishing triumphs as well as devastating second-order effects. Deploying a wonderfully rich and diverse cast of protagonists, from the justly famous to the unjustly obscure, across four generations of explosive growth in the Valley, from the forties to the present, O'Mara has wrestled one of the most fateful developments in modern American history into magnificent narrative form. She is on the ground with all of the key tech companies, chronicling the evolution in their offerings through each successive era, and she has a profound fingertip feel for the politics of the sector and its relation to the larger cultural narrative about tech as it has evolved over the years. Perhaps most impressive, O'Mara has penetrated the inner kingdom of tech venture capital firms, the insular and still remarkably old-boy world that became the cockpit of American capitalism and the crucible for bringing technological innovation to market, or not. The transformation of big tech into the engine room of the American economy and the nexus of so many of our hopes and dreams--and, increasingly, our nightmares--can be understood, in Margaret O'Mara's masterful hands, as the story of one California valley. As her majestic history makes clear, its fate is the fate of us all.

The threat of an attack involving an unmanned system armed with a weapon of mass destruction is a present one. With two million drones projected to be flying US skies in 2020, unmanned aircraft systems in the air domain pose a significant challenge to the nation’s security. Other technological advancements, such as artificial intelligence, combined with unmanned systems, have transformed the threat’s very nature, yet the skies are not the only domain of concern. The technology is also developing rapidly in unmanned undersea and surface systems, expanding potential weapons of mass destruction delivery options. This publication is an examination of unmanned aerial systems (UAS), unmanned surface systems (USS), and unmanned undersea systems (UUS). The technological innovation that led to the global commercialization of UAS is underway with USS and UUS. Until recently, no known scholarly studies existed that examined the vulnerabilities of one sector of US critical infrastructure to attack by UAS until A Phenomenological Examination of US Nuclear Power Plants to Attack by Unmanned Aerial Systems was published late in 2020. According to the Nuclear Regulatory Commission (NRC), there had been fifty-seven UAS incursions over twenty-four US nuclear power plants in the past five years, representing one of sixteen sectors of US critical infrastructure (Gardiner 2016; Rogoway and Trevithick 2020; Hambling 2020). Federal departments and organizations have largely ignored the threat potential that UAS pose despite the strategic guidance laid out in the 2017 National Security Strategy of the US. The nation’s national security demands a close examination of the vulnerabilities and is immediately working to close those security gaps. This publication will focus on the emergency of new UAS capabilities and highlight the latest technologies, capabilities, and the significant national security threat implications that UAS, USS, and UUS platforms represent to US critical infrastructure.
