WebA more modern interpretation of the physical content of the original principle of general covariance is that the Lie group GL 4 (R) is a fundamental "external" symmetry of the world. Other symmetries, including "internal" symmetries based on compact groups , now play a major role in fundamental physical theories. Webrotations was reviewed in Sec. 46.11. If S(x) is a scalar field and R specifies a rotation, then the rotated field S′ is given in terms of the original field Sby S′(x) = S R−1x. (19) See Eq. (46.85). This transformation law applies in particular to the wave function of a spin-0 particle, as explained in Sec. 15.2. See Eq. (15.13).
