## Main Question or Discussion Point

If we have motion of system ##S'## relative to system ##S## in direction of ##x,x'## axes, Lorentz transformation suppose that observers in the two system measure different times ##t## and ##t'##.

[tex]x'=\gamma(x-ut)[/tex]

[tex]x=\gamma(x'+ut')[/tex]

Why we need to use the same ##\gamma## in both relations? Why not

[tex]x'=\gamma'(x-ut)[/tex]

[tex]x=\gamma(x'+ut')[/tex]

[tex]x'=\gamma(x-ut)[/tex]

[tex]x=\gamma(x'+ut')[/tex]

Why we need to use the same ##\gamma## in both relations? Why not

[tex]x'=\gamma'(x-ut)[/tex]

[tex]x=\gamma(x'+ut')[/tex]
