The Measurement of Contraction

The theory of relativity is presented as one that cannot be understood
by most people.

That's called "projecting".

This aura of complexity and difficulty is maintained
by using ambiguity and vagueness in describing and defining the theory
and defending it with even more ambiguity and vagueness against logic.
But what is it really? Stripped of all esoteric language it simply
means that physical objects (we may call them frames) that are capable
of motion (cars, trains, planes, the earth, planets, stars) will
shrink along the axis parallel to the motion and have their clocks
slow down. The effects are in proportion to the velocity of the object
and are called length contraction and time dilation.

The "shrink" and dilation are not proportional to the velocity.
Peter, you've seen the formula for Lorentz "gamma". How you could
possibly think it's proportional to velocity?

SR is precise. Peter Riedt just doesn't know what the words mean,
not even words he uses.
