text: # List of Austrian inventions and discoveries
  
  Austrian inventions and discoveries are objects, processes or techniques invented or discovered partially or entirely by a person born in Austria. In some cases, their Austrianess is determined by the fact that they were born in Austria, of non-Austrian people working in the country. Often, things discovered for the first time are also called "inventions", and in many cases, there is no clear line between the two.
