Mach, Ernst (1838–1916)




Ernst Mach
Austrian physicist and philosopher whose name is commemorated in Mach numbers. His greatest influence was in philosophy where he rejected from science all concepts which could not be validated by experience. This freed Einstein from the absoluteness of Newtonian space-time (see absolute space and time), paving the way toward his theory of relativity, and helped inform the logical positivism of the Vienna Circle.
