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.

"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.

Komisár Wallander rieši ďalší záhadný zločin... Opustená farma, krvavé jatky, starý muž, ktorého utýrali a ubili na smrť. Jeho žena leží pri ňom na zemi polomŕtva. Jedného chladného januárového rána o piatej hodine zavolajú vyšetrovateľa Wallandera na miesto činu. Myslí si, že je to rutinný výjazd. Keď však dorazí na farmu, nájde dve obete nezmyselného násilia. Tak to vyzerá na začiatku. Wallanderov život je v troskách, žena ho opustila, dcéra sa s ním nerozpráva a ani jeho starnúci otec nemá preňho pochopenie. Stále pracuje, zle sa stravuje, noci prepije sám v opustenom byte. Teraz však musí zabudnúť na svoje problémy a pustiť sa do boja s časom.

Ein Polizist, der krumme Dinger dreht, hält sich für besonders clever. Soviel Cleverness bricht ihm den Hals...

Geld macht zwar nicht glücklich, aber es beruhigt ungemein. Diese Überzeugung macht die drei Männer zu Komplizen. Sie sind bereit, jeden Preis dafür zu zahlen.Aber ihre Rechnung geht nicht auf. Denn daß Geld auch den Charakter verderben kann, das haben sie nicht einkalkuliert. Und für diesen Fehler müssen sie teuer bezahlen ... (Dieser Text bezieht sich auf eine frühere Ausgabe.)
