John Glen (physicist)

from Wikipedia, the free encyclopedia

John Glen (born November 6, 1927 in London ) is a British physicist who made significant contributions to the description of the dynamics of glaciers . His experimental work on the deformation of ice in the 1950s led to the formulation of a general law of flow for ice, Glen's law of flow, named after him .

Life

Glen was born in London in 1927 and studied engineering and then physics at Clare College , Cambridge . During his doctoral thesis he worked on the physical properties of ice and carried out laboratory experiments on ice deformation. After completing his doctorate at Cambridge University, after a short stay at the Atomic Energy Research Establishment in Harwell, he worked as a lecturer and later as a reader at the University of Birmingham . His greatest scientific contribution was conducting flow experiments with ice blocks in the laboratory at different temperatures and applied stresses , through which he found a relationship between deformation and stress known as Glensches law of flow .

He organized a series of symposiums entitled The Physics and Chemistry of Ice , was chief editor at the Journal of Glaciology from 1961–1984 and was a member of the editorial board until after his retirement . In 1972 he received the Seligman Crystal and in 2013 the Richardson medal from the International Glaciological Society . He is also one of only six honorary members of this society.
