Two remarkable discoveries - Deepstash

Two remarkable discoveries

  • Pasteur found that heating beverages to a temperature between 140F to 212F (60°C-100°C) killed bacteria in those liquids - a process known as pasteurization.
  • He also turned his attention to the development of vaccines. He used artificially weakened viruses as vaccines and went on to develop a vaccine for anthrax and rabies.

Pasteur provided the proof for the existence of the germ theory of disease and revolutionized the way we think about human health.

Before Pasteur, people believed the doctrine of "spontaneous generation" - that life spontaneously appeared from non-living matter.

This theory was used to explain why food spoiled and how infection developed. Pasteur disproved this theory.

Pasteurization
  • It is the process of applying low heat to kill pathogens and extend shelf life of food and beverage products.
  • The process does not eliminate bacterial spores, so it doesn't truly sterilizes products.
  • Pasteurization earlier use was to improve the flavor or food and beverages but not it's primarily for food safety.
  • It greatly reduces risk of food poisoning.

Wilhelm Rontgen

The German scientist was the first person to identify electromagnetic radiation in a wavelength that we today know as an x-ray.

The most common usage of x-rays includes detecting broken or fractured bones, heart problems, breast cancer, scoliosis, and tumors. X-ray machines are used to help save the lives of millions of people.
