Anders Celsius magnitude (a measure of brightness) of certain stars. This was the first attempt to measure the intensity of starlight with a tool other than the human eye. He made observations of eclipses and various astronomical objects and published catalogues of carefully determined magnitudes for some 300 stars using his own photometric system (mean error=0.4 mag). Celsius was the first to perform and publish careful experiments aiming at the definition of an international temperature scale on scientific grounds. In his Swedish paper "Observations of two persistent degrees on a thermometer" he reports on experiments to check that the freezing point is
Fujitsu Celsius was used to stitch together thousands of individual photographic images to create large-scale 360-degree panoramic images: an 80-gigapixel image of London was published in November 2010, stating: “using this excellent workstation allowed this record-breaking photo to be created a few weeks faster than would have been possible on any other available PC.” The 320-gigapixel photomosaic of London published in February 2013 was prepared on a Celsius R920 in three months' time.
