Important table of logarithms and trigonometric functions by the Austrian soldier who taught mathematics at the Artillery School in Vienna. His seven figure log tables were based on those of Vlacq and were famed for their accuracy. The calculations were done with the help of soldiers who were given a gold ducat for every mistake they found. In September 1802 George, or Jurij, Vega was reported missing, and his body later was found in the Danube near Vienna; officially the death was an accident, but many suspected murder.
