You Dirk are wrong educated at home, and are incapable to understand the
problem. I don't like to measure the length but I like to see
what will see an observer in K1 if he uses the LT. Obviously if he uses the
Galilei transformation he obtains the same length as it is determined
in K2. Because you aren't imbecile you will see that if do not use any
coordinate system attached to the train, the length and the time do
not change (do not become relative notions), again observed from the
K1. Can you say what is that, that makes the mess? I believe that
imbecile is that who learned you that the length is shortening when is
used the LT. In reality the length remains constantly with the same
length but people like you are incapable to understand it.
