We are surrounded by images as never before: on Flickr, Facebook, and YouTube; on thousands of television channels; in digital games and virtual worlds; in media art and science. Without new efforts to visualize complex ideas, structures, and systems, today"s information explosion would be unmanageable. The digital image represents endless options for manipulation; images seem capable of changing interactively or even autonomously. This volume offers systematic and interdisciplinary reflections on these new image worlds and new analytical approaches to the visual. Imagery in the 21st Century examines this revolution in various fields, with researchers from the natural sciences and the humanities meeting to achieve a deeper understanding of the meaning and impact of the image in our time.The contributors explore and discuss new critical terms of multidisciplinary scope, from database economy to the dramaturgy of hypermedia, from visualizations in neuroscience to the image in bio art. They consider the power of the image in the development of human consciousness, pursue new definitions of visual phenomena, and examine new tools for image research and visual analysis.
