Tyndall
Proper noun A British physicist of Irish birth, John Tyndall, renowned for his significant experimental work in the 19th century. His research focused on the properties of gases, including their transparency, their absorption of radiant heat, and the transmission of sound through the atmosphere. He is famously credited with providing the first scientific explanation for why the sky appears blue during the day.
The word "Tyndall" is used almost exclusively as a proper noun to refer to the historical figure, John Tyndall, or to phenomena and effects named after him. * The Tyndall effect is the scattering of light by colloidal particles or particles in a fine suspension, which causes phenomena like the blue sky. * John Tyndall's lectures and writings helped popularize science in the Victorian era.
- Tyndallization: A historical, fractional sterilization method involving intermittent heating, named after John Tyndall's related work on spontaneous generation and heat resistance of bacterial spores.
- Tyndall beam: A visible beam of light passing through a colloid, made visible by the Tyndall effect, such as a sunbeam in a dusty room or the beam from a car's headlights in fog.
- Tyndall effect (noun): The physical phenomenon of light scattering.
- Tyndall scattering (noun): A more technical term for the Tyndall effect.
- Tyndallometer (noun): An instrument for measuring the concentration of particles in a gas or liquid by using the Tyndall effect.
