The term
The Lorentz Transformation (aka
This was termed
Relativity shows how even though you and your surroundings may be
in motion, that motion isn't evident unless you can observe something
moving relative to you. In addition to Einstein's conceptions, the
term is also used for earlier explications of this concept, that
didn't take into account factors evident more recently when Einstein
tackled the problem, e.g., While Einstein's relativity gives up the concepts of absolute time, simultaneity, and distance, i.e., identical in all Frames Of Reference (i.e., the same no matter what your speed sand direction you are moving while you measure), it does have a minimal times and distances between events. **Proper Time**is a minimum possible time between two events, which a pair events have only if there is a*frame of reference*in which they are in the same place:*proper time*, is time measured in that frame.**Proper Distance**is the minimum possible distance between two events, which a pair events have only if there is a*frame of reference*in which they take place at the same time:*proper distance*, is distance measured in that frame. It may be referred to as**Proper Length**, e.g., if speaking of an object stretching from one event location to the other.
