Ernst Mach of experimental physics concentrated on the interference, diffraction, polarization and refraction of light in different media under external influences. From there followed important explorations in the field of supersonic fluid mechanics. Mach and physicist-photographer Peter Salcher presented their paper on this subject in 1887; it correctly describes the sound effects observed during the supersonic motion of a projectile. They deduced and experimentally confirmed the existence of a shock wave of conical shape, with the projectile at the apex. The ratio of the speed of a fluid to the local speed of sound "v"/"v" is now called the Mach number. It
Mach Five kind of terrain (firm, icy, unsteady ground, and significant slopes). Control G = Homing robot (As in the original) When pressed, the Mach Five releases a remote control robot bird capable of transmitting footage back to the Mach Five from wherever it is. This function wasn't used in the film. In the 1959 movie "On the Beach" Dr Julian Osborne (played by Fred Astaire) races in a white number 5 Ferrari while wearing a white helmet and goggles—eerily similar to Speed Racer in the Mach Five. In the animated 2008 series, which takes place about 40 years after the events
