Talk:Lorentz–Lorenz equation

Lorenz in German is pronounced the same as Lorentz in Dutch... -- Myria 06:50, 9 Oct 2004 (UTC)

If LorenTz "derived the formula independently in 1870", he was obviously a bright lad! (As the linked Wikipedia article shows) he was only born in 1853.

Lorenz and his work are often confused with that of the more famous H A Lorentz. In this case, it *might* be a doubled attribution of a single derivation. Note the closeness of dates, 1869 and 1870. An alternative suggestion is that Lorenz (the older man, without a 't') first *publicized* the formula in 1869 (e.g. at a physics conference), and had it published the following year (e.g. in a journal). Further research could yeasay or naysay this.

(The article may be derived from "The Hutchinson Encyclopedia; September 22, 2003; 191 Words  ... the mathematical relationship between the refractive index and the density of a medium was published by Lorenz in 1869 and by Hendrick Lorentz (who discovered it independently) in 1870, and is therefore called the Lorentz-Lorenz formula .

A more natural explanation is that the mentioned dates are just wrong. The original publications seem to be the following: Both authors then published their findings in 1880 in Wiedemanns Annalen: --ulm (talk) 14:08, 28 May 2009 (UTC)
