Advancement in Science

One advancement in science during this time period was the Germ Ttheory. The Germ Theory was a theory made by Louis Pasteur in the mid 1800s. By examining the fermentation process of alcohol, he discovered that microscopic organisms called bacteria were the cause of it. He also discovered that bacteria can be killed by heat. This dicovery led Pasteur to the process of pasteurization which killed germs in liquids like milk. Pasteur soon realized that bacteria caused disease. The Germ Thoery led to more lives being in saved in the operating room and to better sanitation in the cities.
