Re: The mathematical Poincaré-Lorentz transformations

Den 23.09.2024 14:51, skrev Richard Hachel:

Poincaré-Lorentz transformations transpose the present coordinates of a frame of reference R to the homologous coordinates in a frame of reference R'.

 x=12
y=9
z=0
To=-15

If the frame R'(t',x',y',x') move along the x axis in
the frame R(t,x,z,y) at the speed 0.8c,
Then the event with the coordinates
  t = -15 y, x = 12 ly, y = 9 ly z = 0 ly in frame R
Will have the following coordinates in frame R'
  t' = - 41 y, x' = 40 ly, y' = 9 ly, z' = 0 ly
Undefined entities:

d=15
t=0 (perception)
sin a= 0.6
cos a = 0.8
