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.
Tyndall said in 1864, "a long series of experiments enables me to state that probably no two substances at a temperature of 100°C emit heat of the same quality [i.e. of the same spectral profile]. The heat emitted by isinglass, for example, is different from that emitted by lampblack, and the heat emitted by cloth, or paper, differs from both."
Named after John Tyndall, tyndallization [23] is an obsolete and lengthy process designed to reduce the level of activity of sporulating microbes that are left by a simple boiling water method. The process involves boiling for a period of time (typically 20 minutes) at atmospheric pressure, cooling, incubating for a day, and then repeating the ...
The party was led by John Bean, with Andrew Fountaine holding the position of Party President, and other leading members including John Tyndall, Colin Jordan (who served as Activities Organiser), Denis Pirie and Ted Budden. Leese's widow, who had given Jordan access to her home during his time as WDL leader, served as vice-president of the ...
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.
While the roots of the split between Tyndall and Jordan was considered to be the marriage of Jordan to Françoise Dior – who had previously been romantically involved with Tyndall [2] – Tyndall himself stated that the rift between the two men was a consequence of an ideological clash resulting from his rejection of Jordan's endorsement of straight Nazism and his own preference for a more ...
