Most aspects of our private and social lives—our safety, the integrity of the financial system, the functioning of utilities and other services, and national security—now depend on computing. But how can we know that this computing is trustworthy? In Mechanizing Proof , Donald MacKenzie addresses this key issue by investigating the interrelations of computing, risk, and mathematical proof over the last half century from the perspectives of history and sociology. His discussion draws on the technical literature of computer science and artificial intelligence and on extensive interviews with participants. MacKenzie argues that our culture now contains two ideals of proof as traditionally conducted by human mathematicians, and formal, mechanized proof. He describes the systems constructed by those committed to the latter ideal and the many questions those systems raise about the nature of proof. He looks at the primary social influence on the development of automated proof—the need to predict the behavior of the computer systems upon which human life and security depend—and explores the involvement of powerful organizations such as the National Security Agency. He concludes that in mechanizing proof, and in pursuing dependable computer systems, we do not obviate the need for trust in our collective human judgment.

"Trading at the Speed of Light" by Donald MacKenzie explores the transformation of financial markets from face-to-face trading to high-frequency trading (HFT) driven by algorithms. It examines the efficiency HFT brings, alongside the competitive race for speed and its implications for global finance's future.

"Mackenzie has achieved a masterful synthesis of engrossing narrative, imaginative concepts, historical perspective, and social concern." Donald MacKenzie follows one line of technology—strategic ballistic missile guidance through a succession of weapons systems to reveal the workings of a world that is neither awesome nor unstoppable. He uncovers the parameters, the pressures, and the politics that make up the complex social construction of an equally complex technology.

This volume, edited by two of McKenzie's former students, brings together a wide range of his writings on bibliography, the book trade and the sociology of texts.

This book is written for general readers with an interest in science, and offers the tools and ideas for understanding how climate change will affect mountains of the American West. A major goal of the book is to provide material that will not become quickly outdated, and it does so by conveying its topics through constants in ecological science that will remain unchanged and scientifically sound. The book is timely in its potential to be a long-term contribution, and is designed to inform the public about climate change in mountains accessibly and intelligibly. The major themes of the book include: 1) mountains of the American West as natural experiments that can distinguish the effects of climate change because they have been relatively free from human-caused changes, 2) mountains as regions with unique sensitivities that may change more rapidly than the Earth as a whole and foreshadow the nature and magnitude of change elsewhere, and 3) different interacting components of ecosystems in the face of a changing climate, including forest growth and mortality, ecological disturbance, and mountain hydrology. Readers will learn how these changes and interactions in mountains illuminate the complexity of ecological changes in other contexts around the world.

Jednoho lednového mrazivého rána zazvoní inspektoru Wallanderovi telefon. Vypadá to na rutinní případ. Když však detektiv přijíždí na osamocenou švédskou farmu, objevuje krvavou lázeň. Starší muž byl mučen a ubit. Farmářova žena, škrcená zvláštním uzlem, umírá vzápětí v nemocnici. Před smrtí však stačí zašeptat „cizinec“. Jediné slovo, které rozpoutá vlnu násilí proti žadatelům o azyl z nedalekého uprchlického tábora. Události se chopí média a začnou hrát na národní strunu, což vyhovuje různým střetům, které zapříčiní laxní přístup státních orgánů. Netrvá to dlouho a jeden z nich skončí podpálením tábora a chladnokrevným zavražděním somálského uprchlíka. Má však komisař opravdu sledovat stopu cizinců? Vždyť bratr zavražděné ženy odhalil nové skutečnosti, které vyšetřování Wallanderova týmu komplikují. Tlak na komisaře se zvyšuje, je třeba jednat rozhodně, s chladnou hlavou a nenechat se vtáhnout do pasti všudypřítomné xenofobie. Série Wallander: https://www.pitaval.cz/serie/483-wallander
