    "Without water vapor, the Earth's surface would be held fast in the iron grip of frost."
    Tyndall began studies of Radiative properties of various gases. His experiments demonstrated that water molecules are the best absorber of heat and energy. He was able to conclude that water vapor is the strongest absorber and most important gas controlling the temperature of Earth's surface. https://earthobservatory.nasa.gov/features/Tyndall
  • Tyndall Effect

    Tyndall Effect
    The Tyndall effect is one of John Tyndall's most popular discoveries. The effect is the scattering of light as it passes through a colloid. Suspension particles reflect the light and make the beam of light visible to our eyes.
    Here is a link to a Khan academy video that does a great job demonstrating the effect

  • Belfast Address

    Tyndall addressed a "controversial" subject. He urged the world to study from a naturalistic view rather than a theological view. Many state this started the Science vs. Religion "war."
  • Spontaneous Generation

    Along with Pasteur, Tyndall was able to prove that no organisms were produced in pure air.
