George Frederick Charles Searle

George Frederick Charles Searle (* December 3, 1864 in Oakington, Cambridgeshire, † November 16, 1954 ) was a British physicist and lecturer.

In 1888 he began working in the Cavendish Laboratory under JJ Thomson. This work he continued in the next 55 years. At the University of Cambridge, he was from 1900 to 1935 worked as a Lecturer, a position that included both teaching and experimental research. In 1905 he became a member of the Royal Society. At Cambridge, he received his doctorate in 1912 for Doctor of Science. Searle was married to Mary Alice Edwards. It was also known its opposition to animal testing.

It was important to his work (1896, 1897) for the electromagnetic mass and the velocity dependence of the mass, Wober he realized that the body could not be accelerated beyond the speed of light, as this requires a great infinite amount of energy. Also coined the term the Heaviside ellipsoid, where he found out following Oliver Heaviside that electrostatic fields are contracted in the direction of movement. These trends were later partly in the mathematics of special relativity again.
