I don't understand why an x boost followed by a y boost is different from a y boost followed by an x boost.
Surely only the resultant velocity matters, and isn't time reversal a symmetry of SR?
Similarly, why is the matrix for three simultaneous boosts any different from the product of boosts in the x,y, and z directions?
Could someone clarify?
Thanks a lot!
