Mach believed that sensation was the basis for all knowledge. Mach held very strict criteria for natural science, any phenomena being researched must be experiential to be verifiable. He rejected concepts such as absolute time and space. -
Mach number
"Ratio of the velocity of a fluid to the velocity of sound in that fluid." (Britannica) Mach numbers less then one indicate a subsonic flow, higher then one supersonic flow. This is specific to objects moving in a fluid. -
Mach's Principle
Inertia results from the relationship of an object with all the rest of the matter in the universe. He believed distance wasn't a factor to this effect. -
