Talk:Brans-Dicke theory/to do

Tasks for expert:
 * better explanation of motivation for theory, especially variable gravitational "constant" and Dirac large number hypothesis,
 * explain Jordan "frame", Einstein "frame" [sic],
 * write and link to background articles on decomposition of metric tensor (see Carroll; see problem book for utility in comparing gravitational radiation in Brans-Dicke and other theories with gtr),
 * explain Faraoni critique (weak-field limit),
 * add material comparing exact solutions in most important cases (plane waves, static spherically symmetric perfect fluid balls) and add a good citation
