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
Celsius 41.11 "Celsius 41.11" took place at the Loews theatre in Georgetown (Washington, D.C.) on September 28, 2004 and was attended by the author Jerome Corsi and the sister of the pilot whose plane crashed into the Pentagon on September 11, Debra Burlingame.
