I Judge Original Time & Length Special Relativity

Click For Summary
Original time and length in special relativity are determined by measuring proper time and proper length in an inertial frame of reference (IFR). The twin paradox illustrates that one twin, who remains in an IFR, ages more than the twin who changes frames, leading to different elapsed times due to their distinct paths through spacetime. While some explanations attempt to avoid mathematics, a basic understanding of linear algebra is essential for meaningful discussions about these concepts. The elapsed time on a clock corresponds to the "distance" traveled through spacetime, which varies based on the route taken. Ultimately, a minimum level of mathematical understanding is necessary to fully grasp the principles of relativity.

Set an IFR first. Proper time for the IFR is measured by clocks at rest. Measures at rest show proper length.

One twin stays in an IFR where time to meet brother again ages more. Another twin transfers IFRs, once at least, that makes his time to meet brother again ages less.

What do you mean by mathematical methods? Is high school maths ok or do you want absolutely no maths at all?
 
In relativity, it turns out that the elapsed time measured by your clock is a measure of "distance" traveled through spacetime. Just like with distance between points in space, the "distance" between two events in spacetime depends on the route taken. The twins took different routes between the departure and return events, so have different elapsed times.

I don't think any of that is provable without maths, but it's the correct explanation.
 
It is impossible to talk in a meaningful way about physics without a minimum of math. For the here discussed kinematical effects of the relativistic spacetime model you only need basic linear algebra.
