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]]:

{{cquote|1=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{{ref|LT1904|2}}:

:: $x^\prime = k\ell\left(x + \varepsilon t\right), t^\prime = k\ell\left(t + \varepsilon x\right), y^\prime = \ell y, z^\prime = \ell z, k = 1/\sqrt{1-\varepsilon^2}.$ }}

Notes

:{{note|LT1904|2}}Lorentz (1904) had written $x^\prime = k\ell x^{\prime\prime},$ $t^{\prime} = \ell t/k - k\ell wx^{\prime\prime}/c^2,$ $k^2 = c^2/\left(c^2-w^2\right)$ . Later in the paper he deduced that $\ell = 1.$ Lorentz's $x^{\prime\prime}$ was, in Poincaré's notation, equal to $x - wt.$ Eliminating $x^{\prime\prime}$ and putting $\varepsilon = -w/c$ yields the Lorentz transformations as Poincaré wrote them.
