Putting the New Materialist figure of diffraction to use in a set of readings – in which cultural texts are materially read against their contents and their themes, against their readers or against other texts – this volume proposes a criticalintervention into the practice of reading itself. In this book, reading and reading methodology are probed for their materiality and re-considered as being inevitably suspended between, or diffracted with, both matter and discourse. The history of literary and cultural reading, including poststructuralism and critical theory, is revisited in a new light and opened-up for a future in which the world and reading are no longer regarded as conveniently separate spheres, but recognized as deeply entangled and intertwined. Diffractive Reading ultimately represents a new reading of reading itself: firstly by critiquing the distanced perspective of critical paradigms such as translation and intertextuality, in which texts encountered, processed or otherwise subdued; secondly, showing how all literary and cultural readings represent different ‘agential cuts’ in the world-text-reader constellation, which is always both discursive and material; and thirdly, the volume materializes, dynamizes and politicizes the activity of reading by drawing attention to reading’s intervention in, and (co)creation of, the world in which we live.

This book provides the reader with the broad range of materials that were discussed in a series of short courses presented at Georgia Tech on the design, fabrication, and testing of diffractive optical elements (DOEs). Although there are not long derivations or detailed methods for specific engineering calculations, the reader should be familiar and comfortable with basic computational techniques. This text is not a 'cookbook' for producing DOEs, but it should provide readers with sufficient information to assess whether this technology would benefit their work, and to understand the requirements for using the concepts and techniques presented by the authors.

Diffraction patterns in quantum physics evidence the fact that the behavior of matter is the result of its entanglements with measurement, or as Karen Barad suggests, the entanglement of matter and meaning. In this sense, therefore, phenomena (including texts, cultural agents, or life forms) are the results of their relational, onto-epistemological entanglements and not individual entities that separately pre-exist their joint becoming. As such, ‘diffraction’ proposes a new understanding of difference: no longer a dualist understanding, but one going beyond binaries. Diffraction is about patterns, constellations, relationalities. From this angle, the book explores ‘diffraction’, which has begun to impact critical theories and humanities debates, especially via (new) materialist feminisms, STS and quantum thought, but is often used without further reflection upon its implications or potentials. Doing just that, the book also pursues new routes for the onto-epistemological and ethical challenges that arise from our experience of the world as relational and radically immanent; because if we start from the ideas of immanence and entanglement, our conceptions of self and other, culture and nature, cultural and sexual difference, our epistemological procedures and disciplinary boundaries have to be rethought and adjusted. The book offers an in-depth consideration of ‘diffraction’ as a quantum understanding of difference and as a new critical reading method. It reflects on its import in humanities debates and thereby also on some of the most inspiring work recently done at the crossroads of science studies, feminist studies and the critical humanities. This book was originally published as a special issue of Parallax.

This high level monograph for the optics research market explores a large number of novel interactive methods and algorithms for calculating the transmission function of phase diffractive optical elements. The text includes accounts of well-established methods and algorithms for calculating DOEs, but its major contribution is to include current methods and examine the theoretical and practical aspects of synthesising optical components. All the methods discussed in this book have been verified by their numerical simulation. A fast fourier transform algorithm presents computational basis of all the methods considered. A portion of the algorithms have received a comparative study in terms of their suitability for solving the same problem. For a number of the interactive algorithms a rigorous proof to their convergence is given.

Reimagining the scholarly book as living and collaborative--not as commodified and essentialized, but in all its dynamic materiality. In this book, Janneke Adema proposes that we reimagine the scholarly book as a living and collaborative project--not as linear, bound, and fixed, but as fluid, remixed, and liquid, a space for experimentation. She presents a series of cutting-edge experiments in arts and humanities book publishing, showcasing the radical new forms that book-based scholarly work might take in the digital age. Adema's proposed alternative futures for the scholarly book go beyond such print-based assumptions as fixity, stability, the single author, originality, and copyright, reaching instead for a dynamic and emergent materiality. Adema suggests ways to unbind the book, describing experiments in scholarly book publishing with new forms of anonymous collaborative authorship, radical open access publishing, and processual, living, and remixed publications, among other practices. She doesn't cast digital as the solution and print as the problem; the problem in scholarly publishing, she argues, is not print itself, but the way print has been commodified and essentialized. Adema explores alternative, more ethical models of authorship; constructs an alternative genealogy of openness; and examines opportunities for intervention in current cultures of knowledge production. Finally, asking why it is that we cut and bind our research together at all, she examines two book publishing projects that experiment with remix and reuse and try to rethink and reperform the book-apparatus by taking responsibility for the cuts they make.

Practice Theory and Education challenges how we think about ¿practice¿, examining what it means across different fields and sites. It is organised into four themes: discursive practices; practice, change and organisations; practising subjectivity; and professional practice, public policy and education. Contributors to the collection engage and extend practice theory by drawing on the legacies of diverse social and cultural theorists, including Bourdieu, de Certeau, Deleuze and Guattari, Dewey, Latour, Marx, and Vygotsky, and by building on the theoretical trajectories of contemporary authors such as Karen Barad, Yrjo Engestrom, Andreas Reckwitz, Theodore Schatzki, Dorothy Smith, and Charles Taylor. The proximity of ideas from different fields and theoretical traditions in the book highlight key matters of concern in contemporary practice thinking, including the historicity of practice; the nature of change in professional practices; the place of discursive material in practice; the efficacy of refiguring conventional understandings of subjectivity and agency; and the capacity for theories of practice to disrupt conventional understandings of asymmetries of power and resources. Their juxtaposition also points to areas of contestation and raises important questions for future research. Practice Theory and Education will appeal to postgraduate students, academics and researchers in professional practice and education, and scholars working with social theory. It will be of particular interest to those who wish to move beyond the limiting configurations of practice found in contemporary neoliberal, new managerialist and narrow representationalist discourses.
