Sommario/riassunto

The idea that the digital age has revolutionized our day-to-day experience of the world is nothing new, and has been amply recognized by cultural historians. In contrast, Stephen Robertson’s BC: Before Computers is a work which questions the idea that the mid-twentieth century saw a single moment of rupture. It is about all the things that we had to learn, invent, and understand – all the ways we had to evolve our thinking – before we could enter the information technology revolution of the second half of the twentieth century. Its focus ranges from the beginnings of data processing, right back to such originary forms of human technology as the development of writing systems, gathering a whole history of revolutionary moments in the development of information technologies into a single, although not linear narrative.  Treading the line between philosophy and technical history, Robertson draws on his extensive technical knowledge to produce a text which is both thought-provoking and accessible to a wide range of readers. The book is wide in scope, exploring the development of technologies in such diverse areas as cryptography, visual art and music, and the postal system. Through all this, it does not simply aim to tell the story of computer developments but to show that those developments rely on a long history of humans



creating technologies for increasingly sophisticated methods of manipulating information.  Through a clear structure and engaging style, it brings together a wealth of informative and conceptual explorations into the history of human technologies, and avoids assumptions about any prior knowledge on the part of the reader. As such the expert and the general reader alike will find it of interest.

Sommario/riassunto

This volume showcases state-of-the-art computational methodologies for the description and analysis of non-covalent interactions. Each chapter focusses on a specific approach, outlining a theoretical framework for the method in hand that is then illustrated by cutting-edge applications. A range of energy decomposition analyses and real-space topological and geometrical schemes are covered, providing a menu of approaches from which to draw insight into non-covalent interactions. The book serves as a comprehensive resource for computational chemists, as well as experimental chemists seeking to understand how computational techniques can be applied in their research.
