"Einstein's theory of relativity holds several things sacred. One is the idea that if you rotate a particle or object, or boost it up to a high velocity, the laws of physics affecting the object should stay the same. This is called Lorentz invariance. "  http://www.aip.org/pnu/2002/split/578-2.html

"the symmetry that requires the laws of physics to be the same for all observers is known as Lorentz symmetry."  http://www.cfa.harvard.edu/Walsworth/pdf/PhysicsWorld_2004.pdf 

根据上面两段话,Lorentz invariance 和 Lorentz symmetry 是否一样? 就是爱因斯坦的相对性原理加光速不变?

"Special relativity postulates that all laws of physics are invariant under Lorentz transformations, which includes ordinary rotations and changes in the velocity of a reference frame.  Subsequently quatum field theories all incorporated Lorentz invariance in their basic strcture."  http://physics.princeton.edu/romalis/articles/Pospelov%20and%20Romalis%20-%20Lorentz%20Invariance%20on%20Trial.pdf    根据这段话,Lorentz invariance 是否就是 “all laws of physics are invariant under Lorentz transformations
