Suggestions on getting this in audio form? I guess it requires transcribing the handwritten parts. The Chrome OCR fails there. Is there a better one? Sample: This implies that the universe is spatially homogeneous and isotropic since there is no direction defined in the 3- space orthogonal to Ua. In this universe we consider small perturbations of the motion of tl1e fluid and of the '.ifeyl tensore 1 Ne neglect products of small quantities and perform derivatives with respect to the undisturbed metric. Since all the quantities we are interested in with the exception of the scalars, µ, ~' e have unperturbed value zero, we avoid perturbations that merely represent coordinate transformation and have no physical significance. To the first order the equations (1) - (4) and (7) - (9) are
