John Tyndall (/ ˈ t ɪ n d əl /; 2 August 1820 – 4 December 1893) was an Irish physicist.His scientific fame arose in the 1850s from his study of diamagnetism.Later he made discoveries in the realms of infrared radiation and the physical properties of air, proving the connection between atmospheric CO 2 and what is now known as the greenhouse effect in 1859.
Tyndallization is a process from the nineteenth century for sterilizing substances, usually food, named after its inventor John Tyndall, that can be used to kill heat-resistant endospores. Although now considered dated, it is still occasionally used.
John Hutchyns Tyndall (14 July 1934 – 19 July 2005) was a British neo-fascist political activist. A leading member of various small neo-Nazi groups during the late 1950s and 1960s, he was chairman of the National Front (NF) from 1972 to 1974 and again from 1975 to 1980, and then chairman of the British National Party (BNP) from 1982 to 1999.

The Tyndall effect is light scattering by particles in a colloid such as a very fine suspension (a sol). Also known as Tyndall scattering , it is similar to Rayleigh scattering , in that the intensity of the scattered light is inversely proportional to the fourth power of the wavelength , so blue light is scattered much more strongly than red ...
This article needs attention from an expert in Anthropology.The specific problem is: It is not clear exactly how big of a deal this idea is in anthropology, whether it really is a counterpart to economy-of-effort theory and compatibility with childcare, and an expert would probably be able to identify some sources (or have an old undergraduate textbook on hand) to provide solid grounding.
Spontaneous generation was taken as scientific fact for two millennia. Though challenged in the 17th and 18th centuries by the experiments of the Italian biologists Francesco Redi and Lazzaro Spallanzani, it was not discredited until the work of the French chemist Louis Pasteur and the Irish physicist John Tyndall in the mid-19th century.
The John Tyndall Correspondence Project, which is an international collaborative effort to obtain, digitalize, transcribe, and publish all surviving letters to and from John Tyndall, was initiated by Lightman [14] and funded by the National Science Foundation in 2009. [1]
