ABSTRACT
This chapter considers the possibilities of three kinds of differences for studies of technology, particularly for productively engaging across disciplines and project-ing towards future technology design. Differences also support the re-examining and re-informing of technology studies through drawing attention to the process of imagining design possibilities or project-ing. So how might differences be useful for interdisciplinary work when social scientists and computer scientists with different views on validity converge on description? The nature of the project-ing or analytical strategies is crucial to consider when answering this question. The process of project-ing towards engineering industrial, safety critical systems is quite different from project-ing towards creating playful domestic social technologies. Yet there is also the possibility of the imagining work of project-ing re-informing description through particular disciplinary foci and supporting questions about what kinds of validity are important in the face of the 'description informing design' mantra.
