From the beginning of space astronomy, the extreme ultraviolet band of the spectrum (roughly defined as the decade in energy from 90-900 A) was deemed to be the "unobservable ultraviolet". Pioneering results from an EUV telescope on the Apollo-Soyuz Mission in 1975 forcibly demonstrated that this view was incorrect; but it required the all-sky surveys of the English wide-field camera and the extreme ultraviolet explorer to demonstrate the broad potential of this field. Over 700 EUV sources have now been detected. Over 150 researchers from 16 countries gathered to share results in this field at the International Astronomical Union Colloquium No. 152. Papers were presented on a wide variety of topics including cool star coronae, white dwarf atmospheres and evolution, neutron stars, the Iotorus, cataclysmic variable stars, active galactic nuclei, the interstellar medium, winds and atmospheres of early type stars, and EUV plasma diagnostics. Selected manuscripts from this meeting are provided in these conference proceedings.

The field of extreme ultraviolet astronomy will see two major satellite observatories to be launched in 1991, one by ESA (ROSAT mission), one by NASA (EUVE mission). These Proceedings discuss the potential for EUV Astronomy, results from recent missions, approved and possible future missions and new developments in EUV technology.

Computers are more and more becoming creative tools in music as well as in the visual arts and design. In the last few years, it has become clear that digital technology provides a platform for multimedia productions as well as a medium for new art forms. Computer Music and Computer Graphics & Animation have their own international forums. The need was felt, however, to bring together the diverse disciplines within art and technology in one international event - the First International Symposium on Electronic Art (FISEA). The Symposium attracted considerable interest and hundreds of papers and proposals were submitted, of which a selection were accepted. This book, also published as a supplement to the journal Leonardo, publishes 20 of these selected papers under the editorship of Wim van der Plas, Ton Hokken and Johan den Biggelaar. This richly illustrated issue on Electronic Art reflects the enormous international interest which FISEA generated and will further stimulate interest in applications of new technology in music, visual arts and design.
