What does the practical work of writing contribute to historical writing? What does it mean for historical knowledge that it is, inescapably, written? Henning Trüper explores quotidian practices of writing as constituting the working life of a historian, the Belgian mediaevalist François Louis Ganshof (1895-1980). The argument draws on a large variety of texts and writing situations, so as to discuss, across the fault lines of twentieth-century historiography, shifting patterns of methodological discourse; procedures of historicisation; the making of scholarly sociability in writing practice; and finally the actual writing of historical text. Ganshof the historian, whether as author, reader, teacher, student, polemic, diplomat, witness, or mere voice on the radio, remained bound to paperwork, an ensemble of small-scale routines and makeshift solutions that ultimately lacked a central steering agency. The nexus between historical knowledge and paperwork was indissoluble.

The measurement and characterisation of surface topography is crucial to modern manufacturing industry. The control of areal surface structure allows a manufacturer to radically alter the functionality of a part. Examples include structuring to effect fluidics, optics, tribology, aerodynamics and biology. To control such manufacturing methods requires measurement strategies. There is now a large range of new optical techniques on the market, or being developed in academia, that can measure areal surface topography. Each method has its strong points and limitations. The book starts with introductory chapters on optical instruments, their common language, generic features and limitations, and their calibration. Each type of modern optical instrument is described (in a common format) by an expert in the field. The book is intended for both industrial and academic scientists and engineers, and will be useful for undergraduate and postgraduate studies.

This book gives a comprehensive overview of all relevant elements in topography and their practical application. It elaborates on the classical representation of terrain on maps such as cartographic projections, together with their classification, scale, and geographical elements. It is richly illustrated with photographs, maps and figures, in which the theoretical explanations are clarified. Readers will become acquainted with the physical characteristics of the ground, i.e. tectonic and erosive shapes, the importance and classification of terrain, genetic (fluvial, abrasive, glacial, karst) and topographic types such as higher (mountains, hills, peaks) and lower terrain (valleys, fields). In addition, the book discusses cartometry and coordinate systems, orientation in space (geographic, topographic, tactical) including by means of maps, instruments and the night sky and elaborates new techniques and technologies such as aerial photogrammetric imagery, global navigation satellite systems and LiDAR. The book also includes methods for the practical execution of concrete measurement operations, such as determining position and movement on land with maps, compass and azimuth which makes it especially useful for practitioners and professionals, e.g., for landscape planning, military exercises, mountaineering, nature walks etc. As such it offers a valuable guide not only for undergraduate students but also for researchers in the fields of geography, geosciences, geodesy, ecology, forestry and related areas looking for an overview on topography. Uniquely, the book also features an extensive glossary of topographical terms.

This book has been written to provide research workers with an introd- tion to several optical techniques for new applications. It is intended to be comprehensible to people from a wide range of backgrounds - no prior optical or physics knowledge has been assumed. However, sufficient technical details have been included to enable the reader to understand the basics of the techniques and to be able to read further from the ref- ences if necessary. The book should be as useful to postgraduate students and experienced researchers as those entering the bioengineering field, irrespective of whether they have a technical or clinical background. It has been prepared with an awareness of the inherent difficulties in und- standing aspects of optics which, in the past, have precluded practical application. The contents address a broad range of optical measurement techniques which have been used in biomechanics, techniques characterized as n- contacting and non-destructive. Theoretical outlines and practical advice on gaining entry to the fields of expertise are complemented by biomec- nical case studies and key literature references. The aim is to present each technique, to appraise its advantages and capabilities and thereby to allow informed selection of an appropriate method for a particular app- cation. It is anticipated that research workers will be assisted in est- lishing new methodologies and gain first-hand experience of the techniques.
