I remind for those who are passionate about relativity, or who just want
to understand how things work, because they are curious, I asked two small
problems today in order to open practical discussions on numerical
examples.
This allows you to visualize what you are talking about (rockets, bridges,
trains) with fun and user-friendly examples.
This makes it possible to reflect on the question in a more natural and
pleasant way than to stuff yourself with incomprehensible texts learned by
heart without really understanding them.
Texts like "there is a time jump by change of frame of reference", or "the
lengths contract" or "the andromedians will attack us, but we will be
warned thanks to a space-time diagram", I humbly admit not not understand
them.
It is very strange that I do not understand, whereas what I am writing, I
understand it very well. And he is even stranger than the others, who say
they understand "very well" what relativists write, do not understand what
I write, in simpler terms and with much less complex equations.
So I let the readers who want to have a little fun on the problems I give
to show their mastery of SR by clearly answering my small and simple
questions.

Einstine was a *kenseto* we have today. No math, no anything, but
importing. He stole his tensors.

Too bad that you have no clue about even the basics of it.

Therefore, you are not in a position to give people problems in this area to
solve, because you yourself do not know the correct answer (unless you
happened to cheat).

I Hope you are kidding.
