Abstract

The increasing use of computer simulations in science expands the scientific production of knowledge: theory, experiment, and now simulations. "Semiotik and Simulation" analyses the semiotical aspects of the numerical simulation and its visualisation. The main hypothesis is that the simulation in not only a new way of knowledge production it is also a new system of symbol production. Refering to Nelson Godmans "Languages of Art" this new system is characterised by iconic and letter based qualities. First an analyse of the use of letters for symbol production (formal languages and algorithms) and of the transformation of spatial fixed letters into the fluid medium of the computer is given. To transform letters and alphabets into a fluid medium means to code spatial qualities in a temporal and transitory way: the creation, storage, and presentation of signs fall apart; the scheme of symbols of the digitalised signs is not longer based on individual signs but on homogeneous conditions of a machine; signs receive a multimedia presentation, they can be shown as letters, pixels of an image, or sound; and the computer enables the technology of overwriting as a new function of digital signs. The digital alphabet consists of 265 signs, all discrete and digital distinct. In the way of Goodmans theory of symbols the digital alphabet is a system of symbols which follows the syntactical attitudes of written language but is not longer realised visually at most presented so. The digital signs allow the creation of the familiar system of written letters on the computer screen or print but allow also an new one: the simulation and its visualisation. Simulations use the technology of overwriting as recursive calculations and the multimedia presentation to show the calculated values as pixels of an image. The enormous capacity of computers produces a semiotical quantity of values and pixels which creates an increasing semiotical density of the visualisation. Density is a quality of iconic systems and the visualisation of simulation "simulates" the density of images. Using innovative 3-d-technologies of visualisation the results of simulations receive a plastic extension in our space of perception (e.g. molecular modeling). Therefore the symbol system of simulation can be used to create semiotical objects which expand the potential of knowledge production in science.
