WebNow let a photon move along the x-axis (and hence also along the x′-axis) and pass both origins when they coincide at t = t′ = 0. Then the x coordinate of the photon as seen by O is x = ct, and the x′ coordinate as seen by O′ is x ′= ct . Note that the value of c is the same for both observers. This is assumption (2). Web8. Right. Just linguistically, "invariant" is composed of "in" and "variant" and it just means "not change" - invariants don't change. "Form-invariant" (surely less common in fundamental physics!) means that "form doesn't change" for the same reason. The term "covariant" is linguistically "co" and "variant" which means "together change ...

WebLorentz covariance: operators in quantum field theory must be Lorentz covariant. How to apply these principles to the internal structure • For nucleon, one has the quark, gluon momentum, orbital angular momentum and spin operators either satisfy the canonical quantization rule or gauge invariance but no one satisfies both.
