Arthur Mason Worthington

Arthur Mason Worthington CB, FRS (11 June 1852 in Manchester – 5 December 1916 in Oxford) was an English physicist and educator. He is best known for his work on fluid mechanics, especially the physics of splashes; for observing those, he pioneered techniques of high speed photography. He also proposed the slug as a unit of inertial mass, and the pound-foot as a dedicated unit of torque.

He was Science Master at Clifton College, Bristol (1877, 1880-1884) and then Headmaster at the Royal Naval Engineering College, Devonport.

In June 1893 he was elected a Fellow of the Royal Society. His candidacy citation read:

Head Master and Professor of Physics, Royal Naval Engineering College, Devonport. Distinguished as a physicist, especially for his researches on surface tension and on the stretching of liquids. Author of the following papers: - 'On the Forms assumed by Drops of Liquid falling Vertically on a Horizontal Plate' (Proc Roy Soc, 1876-1877); 'On the Spontaneous Segmentation of a Liquid Annulus' (ibid, 1879); 'On Pendent Drops' (ibid, 1881); 'On Impact with a Liquid Surface' (ibid, 1882); 'On the Horizontal Motion of Floating Bodies under the Action of Capillary Forces' (Phil Mag, 1883); On the Surface Forces in Fluids' (ibid, 1884); 'On the Error involved in Prof Quincke's Method of Calculating Surface Tensions from the Dimensions of Flat Drops and Bubbles' (ibid, 1885); 'A Capillary Multiplier' (ibid); 'On Tensional Stress and Strain within a Liquid' (Brit Assoc, Sect A, 1888); 'On the Discharge of Electrification by Flames' (Brit Assoc, Rept Electrolysis Comm, 1889); 'on the Mechanical Stretching of Liquids, an Experimental Determination of the Volume-Extensibility of Ethyl Alcohol' (read before the Roy Soc, Feb 4, 1892).
