Voluble is a dynamic space-time diagram of the solar system. Voluble is designed to help users understand the
relationship between space and time in the motion of the planets around the sun. Voluble is set in virtual reality to relate
these movements to our experience of immediate space. Beyond just the visual, understanding dynamic systems is
naturally associated to the articulation of our bodies as we perform a number of complex calculations, albeit
unconsciously, to deal with simple tasks. Such capabilities encompass spatial perception and memory. Voluble
investigates the balance between the visually abstract and the spatially figurative in immersive development to help
illuminate phenomena that are beyond the reach of human scale and time. While most diagrams, even computer-based
interactive ones, are flat, three-dimensional real-time virtual reality representations are closer to our experience of space.
The representation can be seen as if it was "really there," engaging a larger number of cues pertaining to our everyday
The Sloan Digital Sky Survey(SDSS) is a redshift factory producing more than 5000 spectra a night when conditions allow. In order not to fall behind the data acquisition, highly automated and accurate spectral reduction pipelines are needed to process the data. Also the varied nature of SDSS target selection: the main galaxy sample, the large red galaxy sample, the QSO sample, stellar targets, and serendipitous objects; requires the pipeline to be adept at handling the full range of astronomical spectra, from a redshift of 0 out to a redshift of 6. The SDSS spectra are of exceptionally high quality, allowing the pipeline not only to determine redshifts and broadly classify the spectra, but also measure line parameters, calculate spectral indices, velocity dispersions etc. The purpose of this summary is to give an overview of the workings of the pipeline and its outputs, and give some guidance in using those outputs.
