Early Work
A. A. Griffith took a first in mechanical engineering, followed by a Master’s Degree and a Doctorate from Liverpool University. In 1915 he was accepted by the Royal Aircraft Factory as a trainee, before joining the Physics and Instrument Department the following year in what would soon be renamed as the Royal Aircraft Establishment (RAE).
Some of Griffith's earlier works remain in widespread use today. In 1917 he and G. I. Taylor suggested the use of soap films as a way of studying stress problems. Using this method a soap bubble is stretched out between several strings representing the edges of the object under study, and the coloration of the film shows the patterns of stress. This method, and similar ones, were used well into the 1990s when computer power became generally available that could do the same experiment numerically.

Famous quotes containing the words early and/or work:
“The girl must early be impressed with the idea that she is to be “a hand, not a mouth”; a worker, and not a drone, in the great hive of human activity. Like the boy, she must be taught to look forward to a life of self-dependence, and early prepare herself for some trade or profession.”
—Elizabeth Cady Stanton (1815–1902)
“You are made
Rather to wonder at the things you hear
Than to work any.”
—William Shakespeare (1564–1616)
