What did Louis Pasteur's work show?

Answer 1

Louis Pasteur conducted a number of ground breaking experiments throughout his life. One was the disproving of the notion of spontaneous generation. Prior to this, there was the assumption that some life could spontaneously arise from nothing- such as the idea that maggots could appear from nowhere in a piece of rotten meat. In his experiment, Pasteur showed that while a piece of rotten meat attracted maggots, a piece of meat covered with a mesh just small enough to prevent flies from landing did not- indicating that flies had to deposit eggs for maggots to form. Also he developed the sterilization technique of pasteurization and invented a rabies vaccine.
