Ernst Mach Ernst Mach Ernst Waldfried Josef Wenzel Mach (; ; 18 February 1838 – 19 February 1916) was an Austrian physicist and philosopher, noted for his contributions to physics such as study of shock waves. The ratio of one's speed to that of sound is named the Mach number in his honor. As a philosopher of science, he was a major influence on logical positivism and American pragmatism. Through his criticism of Newton's theories of space and time, he foreshadowed Einstein's theory of relativity. Ernst Waldfried Josef Wenzel Mach was born in Chrlice (), Moravia (then in the Austrian empire, now

Many flight simulators have replicated the Mach Loop in Wales, but a notable one is present in the FlightGear flight simulator, created by the FGUK community as an add-on for the simulator, providing the player with the challenge of guiding aircraft at high speed through rings that mark the route. In addition, the scenario has "start" and "finish" points, and each run in the Mach
