In this class, you look at the energy momentum for a particle, for example, for a system.
00:06
The energy momentum, for example, in the frame, k and in k prime, in k, it has e, i think, one of the questions, px, and in this k prime is e prime, px prime, and p1 and pz are the same, because i think the transformation, i mean, these two can and k frame obviously move relative to each other on the x axis.

To 1 and z are the same by symmetry.
00:33
And to work out the relationship between this, you're just into play a lot of interest transformation.
00:37
But you have to realize that the lorenz transformation actually works on, put a speed of light here, c and speed up right here...
