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 Rider on it. When the car is placed inside of it, it can be charged up and let loose at high speed. Later, "Mach Rider" was released as part of the "Nintendo Vs. Series" arcade variations. It was essentially a modified version of the Endurance Course from the original game. Each time the player completed a level, a bit more of an image was gradually revealed of a woman with a dagger appears next to Mach Rider's bike. While "Mach Rider" has not gained a true sequel, many elements from the game, such as the futuristic setting, incredible high speeds and
