comment Why Lorentz Transformation in Special Relativity has to be like this?
@luksen: 1. indicates that the transformation must be linear; 2. indicates that the eigenvectors of that transform matrix must be (c, 1) and (-c, 1); 3. reveals the matrix (1, -u; -u/c^2, 1), but with an unknown factor; and 4. given by you finally provides the factor 1/sqrt(1-u^2/c^2). Wonderful!

@luksen: I think you have a good point. This should be the fourth postulation in my list.

No, it won't, you will temporarily rotate a little and stay still with your shoulders pushed, but you will immediately back to your orientation when you get back to your original pose.
