VIENNA.- Combining the media of photography, sculpture, and drawing, the works of Hungarian-born artist Attila Csörgő offer viewers an ironic and humorous introduction to questions of science and technology. The results are often unexpected, amusing, or even poetical. In long-term experiments the artist explores branches of science such as kinetics, optics, or geometry to examine questions of perception; and on this basis he develops his theories about the construction of reality. His photographs capture sequences of motion or energetic processes, which appear as traces of light, making phenomena visible that, under normal conditions, are not or only barely perceptible to the human eye. While such processes rely on scientific and mathematic calculations, the artist frequently assembles his technological arrangements from everyday objects and materials. Element by element, his transparent systems sharpen our
