Toronto. We all (almost all) can remember Dr Harold Edgerton of M.I.T. and his famous speed light shots in the early days of electronic flash. These shots allowed us to see phenomenon that was too brief for the human eye to observe. One famous photo was his 1957 record of the milk drop coronet.
Few of us however, have heard of Arthur Mason Worthington, FRS. He was a British Physicist who pioneered high speed photography decades before Edgerton’s remarkable work in Boston. Worthington, a professor in fluid mechanics used an electric spark to create short duration illumination to record splashes photographically.
A tip of the hat to member George Dunbar for this reminder of the century plus experiment in speed light in Britain.
