| 21. | All of those experiments confirmed Lorentz invariance and special relativity.
|
| 22. | However, strict measurement invariance rarely holds in applied context.
|
| 23. | :The evidence here is the evidence that Lorentz invariance is valid.
|
| 24. | A theory that displays local gauge invariance is called a gauge theory.
|
| 25. | By gauge invariance, all points along these lines are physically equivalent.
|
| 26. | This violates Galilean invariance, a long-standing cornerstone of classical mechanics.
|
| 27. | Such geodesics are the generalization of the invariance of lightspeed in special relativity.
|
| 28. | The invariance of light speed is one of the postulates of special relativity.
|
| 29. | In classical music, Bach used the symmetry concepts of permutation and invariance.
|
| 30. | These desirable properties may be described as : validity, optimality and invariance.
