  Special relativity postulates that inertial frames are equivalent.
Length contraction and time dilation follow directly from the coordinate
transformation that leaves inertial frames inertial. If you understand why
rotating in the x-y plane about a point on the stick changes the lengths
of the x and y projections but leaves l^2 = l_x^2 + l_y^2, invariant, then
you have no excuse for not understanding why rotating the same stick in
the x-t plane (a boost) changes the the x and t projections but leaves
t^2 - x^2 invariant. It's as simple as that. If you can't understand the
pythagorean theorem just because the one you used in high school was
limited to a special case, you need a different hobby. To understand
special relativity, you have to get used to the idea that there's more
to geometry than what you learned as a highschool freshman.

  If you actually knew what special relativity did say, you might be
embarrassed by the content of those articles you post so repetitiously.
