User:Michael Hardy/templates within templates

Putting the "ref" template inside the "cquote" template can occasion technical difficulties. The solution below was proposed by user:Ligulem. Michael Hardy 00:07, 18 September 2006 (UTC)

Excerpt from Henri Poincaré:
The essential point, established by Lorentz, is that the equations of the electromagnetic field are not altered by a certain transformation (which I will call by the name of Lorentz) of the form:
 * $x^\prime = k\ell\left(x + \varepsilon t\right), t^\prime = k\ell\left(t + \varepsilon x\right), y^\prime = \ell y, z^\prime = \ell z, k = 1/\sqrt{1-\varepsilon^2}.$
